Above 30 degrees paint temperature the cleaner flashes off before the dwell time is up — leaving dull streaks that only come off with polish.

In full summer sun, reach for the milder Pre-Foam efficient instead, which is far more forgiving with its 1-minute maximum dwell time.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003e1:30 for insects. 1:300 for high pressure.\u003c\/h3\u003e\n\u003cp\u003eDilution depends on how dirty the vehicle is and how you apply it. 1:30 to 1:50 for the pre-wash, 1:3 to 1:10 for heavily soiled wheels, 1:300 for self-service high-pressure units.\u003c\/p\u003e\n\u003cp\u003eFor the touchless pre-wash with a foam lance you work at 1:30 to 1:50. One litre of concentrate at 1:50 gives you 51 litres of ready-to-use solution — enough for roughly 20 to 25 cars in standard exterior care.\u003c\/p\u003e\n\u003cp\u003eThe foam lance should run at 0.8 to 1.2 litres per minute flow so the foam consistency is right and the cleaner clings to vertical panels long enough to do its job. Apply the pre-cleaner from the bottom up onto the cold, pre-wetted vehicle — that way you avoid run marks on unevenly dried panels. After 5 minutes dwell time at most (VDA Class A), rinse off thoroughly with the pressure washer.\u003c\/p\u003e\n\u003cp\u003eIn self-service wash bays, 1:300 is enough — that's the high-volume dilution and it cuts product use noticeably over a full year. For wheel cleaning you work at 1:3 to 1:10, sprayed straight onto the cold dry wheel, left to dwell for 1 minute at most, then rinsed. Important: don't use it on hot brake discs or warm wheels. The heat speeds up the reaction in an uncontrolled way and raises the risk of dulling on painted alloy wheels.\u003c\/p\u003e\n\u003cp\u003eFor wash tunnels with conveyor lines you typically run 1:100 to 1:200. Dwell time in the tunnel is usually 30 to 60 seconds, which still keeps you safely inside the VDA-B limit of 1 minute. The higher dilution cuts foam volume at the spray arch but keeps enough cleaning power thanks to the high active-ingredient concentration.

It also works reliably on baked-on brake dust on steel wheels and on alkali-resistant painted alloy wheels. The foam is functional — not the show foam you get from classic snow-foam products, but a working foam that clings to vertical panels.\u003c\/p\u003e\n\u003cp\u003eNow the honest read on the limits. First, the Vorreiniger B is not friendly to active ceramic coatings. Used regularly on coating-protected vehicles it breaks the coating down faster than a pH-neutral pre-wash foam does. For vehicles with an active coating, the milder Pre-Foam efficient is the better call. Second, don't use it on polished aluminium or chrome surfaces — despite the corrosion inhibitors, pH 13.1 can dull untreated light metals. The inhibitors protect anodised alloy, not bare alloy.\u003c\/p\u003e\n\u003cp\u003eThird: it is not paint-surface gentle in the sense of a hand-wash chemistry. If you look after your new car with the two-bucket method and a mild car shampoo, you don't need a Vorreiniger B in the garage. Its job starts where hand washing no longer cuts it — on heavily soiled vehicles, commercial fleets, utility vehicles and construction machinery.\u003c\/p\u003e\n\u003cp\u003eProtective gear is a must, not optional. Nitrile gloves and safety glasses when mixing and applying. On skin contact, rinse straight away with plenty of water and remove residue with mild soap.

Close it well after use and store it frost-free and dark.\u003c\/p\u003e\n\u003cp\u003eThe material compatibility of the Vorreiniger B has clear limits. Allowed: steel, anodised aluminium, alkali-resistant painted surfaces, glass and standard automotive plastics. Not allowed: polished light metals, bare chrome surfaces, coloured anodised layers (risk of discolouration) and matt-painted surfaces without a protective film.

If you supply express wash lines with extremely short dwell times, reach for the Pre-Wash B. If you need the strongest cleaner for baked-on oil and grease residue on engines and chassis, take the Copo Star BMP-T.

Allow the cleaner to work for 2–5 minutes without letting it dry — in hot weather or direct sunlight, shorten the dwell time and keep the vehicle moist. Then rinse thoroughly with a high-pressure cleaner before proceeding to the shampoo wash. For maximum insect removal, use the cleaner in a more concentrated form on the front area (grille, bumper) and, if necessary, briefly work it in with a soft brush before rinsing.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eAlkaline Pre-Cleaner for Cars — How MultiClean Alkaline Works Chemically\u003c\/h3\u003e\n\u003cp\u003eMost organic contamination on vehicles — insect residue, pollen, bird droppings, fatty salts from road abrasion, oil film — are stable in the acidic to neutral pH range. A highly alkaline cleaner like \u003cstrong\u003eSONAX PROFILINE MultiClean Alkaline\u003c\/strong\u003e shifts the chemical equilibrium: esters and fatty compounds in organic contamination are broken down by saponification reactions under alkaline conditions, and protein structures in insect residues are denatured and dissolved. The result is not mechanical removal, but a chemical destabilization of the dirt — the bond to the paint surface is weakened without the need for mechanical action on the paint.\u003c\/p\u003e\n\u003cp\u003eImportant for correct assessment: Highly alkaline pre-cleaners are not \"universal cleaners\" for all situations. They are optimized for organic, alkali-soluble contamination. Mineral deposits such as water spots, lime scale, or rust inclusions (brake dust as iron particles) hardly react to alkaline attack — for these, acidic special cleaners are needed. MultiClean Alkaline is useful in a duo-wash concept: first alkaline pre-wash (organic contamination), then post-treatment with an iron remover or acidic cleaner (mineral deposits). Combining both steps results in a complete chemical cleaning, rather than just appearing clean.\u003c\/p\u003e\n\u003cp\u003eAlso important: Alkaline pre-cleaners must be completely rinsed off before proceeding to the shampoo wash — residues can react with certain sealants or wax coatings and temporarily reduce their adhesion. A thorough high-pressure rinse after the dwell time is sufficient to completely remove the cleaner. On freshly sealed vehicles (ceramic coating, paint sealant), use is only recommended on heavily soiled areas and not for regular weekly washing, to avoid unnecessarily stressing the sealant. For regular vehicle washing of a sealed vehicle, a mild, pH-neutral shampoo is recommended as the standard washing product instead.\u003c\/p\u003e\n\n\u003ch3\u003eProfessional Use of Pre-Wash — Step-by-Step Application\u003c\/h3\u003e\n\u003cp\u003eThe optimal application of \u003cstrong\u003eSONAX PROFILINE MultiClean Alkaline\u003c\/strong\u003e begins on a dry vehicle. Moisture on the paint surface immediately dilutes the cleaner and reduces its effective concentration before it even has time to act. Recommended method: Fill the cleaner, undiluted or at a low dilution ratio (1:3 to 1:10 depending on the degree of soiling), into a pump sprayer, a \u003ca href=\"\/en\/products\/sonax-profiline-foamsprayer-schaumspruher\"\u003eSONAX PROFILINE FoamSprayer\u003c\/a\u003e, or a foam cannon on a high-pressure cleaner and spray evenly onto the entire vehicle — from bottom to top, so the cleaner runs down the bodywork and sufficiently wets even the lower, more heavily soiled areas.\u003c\/p\u003e\n\u003cp\u003eObserve the dwell time: 2–5 minutes are sufficient for typical road grime. Do not let it dry — in direct sunlight or high temperatures, lightly moisten the vehicle intermittently or shorten the dwell time accordingly. After the dwell time, rinse thoroughly with a high-pressure cleaner, then proceed to the normal shampoo wash. Alternatively, MultiClean Alkaline can be used as a foam cleaner in a foam cannon — foam remains on the surface longer and extends the effective dwell time without additional effort. For particularly stubborn insect residues on the front of the vehicle, it is advisable to use a soft insect sponge or microfiber mitt after pre-washing, before rinsing — this is already significantly gentler than direct contact washing without prior chemical pre-wash.\u003c\/p\u003e\n\n\u003ch3\u003eInsect Remover for Professionals — When the Alkaline Pre-Cleaner Shows Its Strengths\u003c\/h3\u003e\n\u003cp\u003eMultiClean Alkaline particularly shows its strengths in the summer season when insects become a real cleaning problem. Insect residues consist of proteins, acids (formic acid, acetic acid), and fatty substances — a chemically complex mixture that \"bakes\" onto paint surfaces if it sits for more than a few hours. The acids contained, in particular, can cause paint damage if insects are not removed promptly in hot weather. The highly alkaline formula neutralizes these acids and simultaneously dissolves the protein structures — making the pre-cleaner an effective tool against insects that minimizes mechanical stress during washing.\u003c\/p\u003e\n\u003cp\u003eA simple rule of thumb applies: The fresher the insect residues, the less dwell time the cleaner needs. Fresh residues can be almost completely dissolved within 2–3 minutes of dwell time and then rinsed off without contact. For older, dried-on residues — which in practice occur on vehicles not washed for several days after a highway drive — a second treatment or a brief mechanical rework with a soft insect sponge may be necessary. This is not a weakness of the cleaner, but a chemical reality: Proteins that have been \"baked\" by heat and UV radiation for days require more time or mechanical assistance to be fully dissolved.\u003c\/p\u003e\n\u003cp\u003eIn addition to car bodywork, its use on motorhomes, vans, and commercial vehicles is particularly useful: Due to their size and mileage, these vehicles often have a much higher dirt load than normal cars, and the possibility of touchless pre-washing significantly saves time and effort in this area. Professional detailing businesses use the pre-cleaner as an integral part of their washing routine — as the first step before high-pressure or foam application begins. This not only increases cleaning quality but also extends the lifespan of wash pads and mitts because they come into contact with significantly less coarse dirt.\u003c\/p\u003e\n\n\n\u003ch3\u003ePre-Cleaner Comparison — MultiClean Alkaline vs. MultiStar and MultiClean Acid\u003c\/h3\u003e\n\u003cp\u003eIn the SONAX PROFILINE range, there are three cleaners that appear similar at first glance but are designed for different tasks.

Both variants contain the same concentrated formula — the optimal dilution depends on the degree of soiling and the application method.

Professional vehicle detailers who use a structured multi-step method (touchless pre-cleaning + foam wash + hand wash) and prioritize paint protection. Hobby detailers who are looking for an effective remedy against stubborn pre-soiling after long-distance drives or during insect season, without having to resort to aggressive chemicals. Vehicle owners with dark or sensitive paint where wash scratches become particularly visible and therefore the mechanical cleaning load should be minimized. And anyone who wants to optimize their washing process: Consistent pre-washing protects the vehicle, washing utensils, and saves time in the long run.\u003c\/p\u003e\n\u003cp\u003eAs a practical workflow for the next car wash: Park the vehicle in the shade, apply MultiClean Alkaline with a foam sprayer or foam cannon, let it work for 3–4 minutes, rinse thoroughly with a high-pressure cleaner. Then apply a \u003ca href=\"\/en\/products\/sonax-profiline-actifoam-energy-reinigungsschaum\"\u003eSONAX PROFILINE ActiFoam Energy\u003c\/a\u003e as a foam wash in the second step and let it work, before starting the hand wash with a wash mitt and pH-neutral shampoo. This three-step approach (alkaline pre-wash → foam → hand wash) is the standard of professional detailing businesses and makes a visible difference in surface quality over time for frequently used vehicles.\u003c\/p\u003e","brand":"SONAX","offers":[{"title":"5 liters","offer_id":53622519365967,"sku":"D1-SNX-6295000","price":28.98,"currency_code":"EUR","in_stock":true},{"title":"1000 ml \/ 1 liter","offer_id":57340506472783,"sku":"D1-SNX-6293000","price":8.64,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/sonax-profiline-multiclean-alkaline-vorreiniger_5-liter.png?v=1731053233"},{"product_id":"sonax-profiline-multiclean-acid-kraftreiniger-sauer","title":"PROFILINE MultiClean \"Acid\" Power Cleaner (Acidic)","description":"\u003ch2\u003eAcidic Power Cleaner for Stubborn Mineral Deposits — SONAX PROFILINE MultiClean Acid\u003c\/h2\u003e\n\n\u003cblockquote\u003e\n  \u003cp\u003e\u003cem\u003eWhat does SONAX PROFILINE MultiClean Acid achieve?

On painted surfaces, only apply for a short period and rinse with plenty of water — acidic cleaners can attack clear coat and delicate surfaces if left on for too long. Protective equipment (gloves, safety glasses) is mandatory when handling acidic concentrates. As a systemic counterpart, we recommend \u003ca href=\"\/en\/products\/sonax-profiline-multiclean-alkaline-vorreiniger\"\u003eSONAX PROFILINE MultiClean Alkaline\u003c\/a\u003e for grease and dirt-related contamination — together, both power cleaners cover the entire pH spectrum of professional vehicle cleaning.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eAcidic Chemistry in Power Cleaners — How MultiClean Acid Dissolves Mineral Contaminants\u003c\/h3\u003e\n\u003cp\u003eThe active principle of the acidic power cleaner is based on the acid-base reaction: Mineral deposits such as calcium carbonate (limescale) and iron oxides (rust) are chemically basic or metallically bound. An acidic cleaner converts these compounds into their ionic form by donating protons — calcium carbonate becomes calcium ions (Ca²⁺) and carbon dioxide (CO₂), iron oxides become soluble iron ions. This is exactly the opposite of the original chemical bond and makes the deposits water-soluble and rinsable, without the need for mechanical force.\u003c\/p\u003e\n\u003cp\u003eThe strength of the acid in the concentrate is chosen to be effective enough to completely dissolve typical limescale and rust deposits within a reasonable contact time — and at the same time, through controlled dilution, it can be safely used on more sensitive substrates. This makes MultiClean Acid more versatile than specialized individual products formulated only for a specific type of contamination and a particular surface. The concentrate offers excellent value for money in professional use due to its versatility and dilutability.\u003c\/p\u003e\n\u003cp\u003eAn important chemical aspect of acidic cleaners is compatibility with various materials. Acid-resistant materials such as stainless steel, ceramics, glass, and many plastics are fully compatible with acidic cleaners. Aluminum and certain light metal alloys, on the other hand, react sensitively — acids can attack aluminum and cause it to become permanently dull or create an oxidative film. Painted surfaces are tolerant with short contact times and sufficient rinsing, but clear coat damage can occur with prolonged contact times or high concentrations. Adherence to recommended contact times and dilutions is therefore not optional, but a fundamental part of safe application.\u003c\/p\u003e\n\n\u003ch3\u003eCorrect Application of MultiClean Acid — Dilution, Contact Time, and Workflow\u003c\/h3\u003e\n\u003cp\u003eApplying the acidic power cleaner requires precise procedures and a dilution rate adapted to the degree of contamination and the surface. For light limescale stains and regular rim cleaning, a dilution of 1:10 to 1:20 (1 part concentrate to 10–20 parts water) is recommended. For medium contamination such as cement film or heavier limescale deposits on tiles and hard surfaces, 1:5 to 1:10. For heavy deposits such as long-dried rust or massive limescale infestation, a dilution of 1:2 to 1:5 or undiluted application may be necessary — here, increased caution is required, and contact with sensitive materials should be avoided.\u003c\/p\u003e\n\u003cp\u003eWorkflow: Moisten the surface with water beforehand to increase the porosity of the substrate and slow down the runoff of the cleaner. Apply the diluted MultiClean Acid generously — spray directly onto horizontal surfaces, apply with a sponge or brush onto vertical surfaces. Contact time 1–5 minutes, depending on the degree of contamination and dilution rate — visible foaming or bubbling reaction during the contact time is a sign that the acid is reacting with the mineral deposits and dissolving them. After the contact time, rinse thoroughly with plenty of water — completely remove rinse water and residues of the acidic cleaner, especially on metal surfaces, which can corrode if acid residues remain.\u003c\/p\u003e\n\u003cp\u003eAfter cleaning with the acidic power cleaner, it is recommended to rinse with a neutral or slightly alkaline solution to completely neutralize any acid residues — especially on rims and metal surfaces that are also to be sealed or cared for after cleaning. For freshly cleaned rims, \u003ca href=\"\/en\/products\/sonax-profiline-ceramiccoating-cc-rim-felgenversiegelung\"\u003eSONAX PROFILINE CeramicCoating \"CC\" Rim\u003c\/a\u003e is suitable as a durable protection that significantly slows down future limescale and brake dust deposits and facilitates subsequent cleaning.\u003c\/p\u003e\n\n\u003ch3\u003eAreas of Application — Typical Contaminants and Surfaces for the Acidic Power Cleaner\u003c\/h3\u003e\n\u003cp\u003eThe acidic professional power cleaner covers a wide range of applications where mineral or acid-soluble contaminants are the main problem. Rim cleaning is one of the most common areas of application: While brake dust does not have a direct affinity for acidic cleaners, limescale deposits from wash water and mineral coatings on rim surfaces are effectively dissolved by the acidic power cleaner. On steel rims and stainless steel rims, use is problem-free — on aluminum rims with increased acid sensitivity, the dilution should be increased and the contact time shortened.\u003c\/p\u003e\n\u003cp\u003eCement film on vehicles and glass surfaces is a common problem for vehicles used near construction sites or during road construction. The white, hard film of cement dust that settles on paint and glass is alkaline and is effectively dissolved by the acidic power cleaner — on glass surfaces (e.g., windshield), application with sufficient rinse water is problem-free and leaves a clear, clean pane. Mineral water spots and limescale rings caused by well water or highly calciferous wash waters are also a classic area of application — MultiClean Acid is the more concentrated professional tool in this segment compared to the \u003ca href=\"\/en\/products\/sonax-profiline-waterspot-remover-wasserfleckenentferner-kalkentferner\"\u003eSONAX PROFILINE Waterspot Remover\u003c\/a\u003e designed for individual care.\u003c\/p\u003e\n\u003cp\u003eIn the area of vehicle underbody cleaning, the acidic power cleaner is effective against limescale and mineral deposits that settle in the underbody — however, combining it with an alkaline pre-cleaner for grease and oil-based contaminants is useful before the acidic cleaner is used for mineral components. Workshop floors, lifting platforms, and sanitary facilities in detailing shops, where limescale and mineral deposits build up, can also be effectively cleaned with the diluted power cleaner — an economical dual use of the large 5-liter container.\u003c\/p\u003e\n\n\u003ch3\u003eAcidic vs. Alkaline Power Cleaner — The Right Choice for Every Type of Contamination\u003c\/h3\u003e\n\u003cp\u003eThe SONAX PROFILINE MultiClean system consists of two complementary power cleaners that together cover the entire spectrum of professional vehicle and surface cleaning. \u003ca href=\"\/en\/products\/sonax-profiline-multiclean-alkaline-vorreiniger\"\u003eSONAX PROFILINE MultiClean Alkaline\u003c\/a\u003e is the alkaline pre-cleaner for grease, oil, and dirt-related contamination — road film, insects, tar, tire abrasion, and organic adhesions are effectively dissolved by the alkaline formulation. MultiClean Acid, on the other hand, is designed for the complementary cleaning area: mineral, calcareous, and rust-related deposits that do not react to alkaline cleaners.\u003c\/p\u003e\n\u003cp\u003eThe rule of thumb: Alkaline cleaner first (road film, grease, organic dirt), acidic cleaner in the second step (limescale, rust, mineral deposits). In practice, many vehicle contaminations are of a mixed nature — a dirty wheel contains both brake dust (metallic\/oxidic), road film (organic), and limescale deposits (mineral). The optimal cleaning result is achieved by sequential application of both cleaners: Alkaline for the initial coarse dirt, Acid for the remaining mineral residues.\u003c\/p\u003e\n\u003cp\u003eCompared to specialized individual products like rim cleaners or descalers, the MultiClean concentrates offer the economic advantage of flexibility: one product, adjustable by dilution, for many different cleaning intensities and surfaces. For detailing shops with different customer vehicles and varying contamination profiles, the systematic MultiClean duo is more economical than a variety of specific individual products — and at the same time significantly reduces storage effort.\u003c\/p\u003e\n\n\u003ch3\u003eBuying SONAX PROFILINE MultiClean Acid — Container Size and Usage Calculation\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eSONAX PROFILINE MultiClean Acid\u003c\/strong\u003e is exclusively available in a 5-liter container, clearly positioning it as a professional product: The container size and concentrate format are designed for continuous professional use, not for occasional private use. At a dilution of 1:10, 5 liters of concentrate yield 50 liters of ready-to-use cleaner — enough for hundreds of rim cleanings or dozens of full vehicle detailings with limescale removal. Even at dilutions of 1:5 for heavier contamination, the container lasts for many cleaning operations.\u003c\/p\u003e\n\u003cp\u003eFor professional detailing shops that clean several vehicles daily and regularly encounter mineral contamination, the 5-liter concentrate is the most economical purchasing decision. The price per liter of ready-to-use cleaner is significantly below the market price for ready-diluted cleaners in consumer containers, depending on the dilution ratio. The investment in the concentrate typically pays off after just a few weeks of regular use compared to using individual ready-to-use cleaners.\u003c\/p\u003e\n\u003cp\u003eAs a systematic addition, we recommend combining it with SONAX PROFILINE MultiClean Alkaline — together, both products form the complete cleaning system for all types of contamination encountered in professional vehicle detailing. Detailing shops that use the MultiClean duo as a fixed cleaning system benefit from a standardized procedure that can be adapted for all vehicle types and contamination profiles and delivers consistently good results.\u003c\/p\u003e\n\u003cp\u003eImportant for businesses that regularly use the concentrate: The product should be stored cool and dry; direct sunlight and frost should be avoided. Seal the container tightly after removal to prevent changes in concentration due to evaporation. In professional use, it is recommended to prepare daily quantities in separate containers — this ensures that freshly diluted cleaner is always used, maintaining consistent cleaning performance. With these simple handling rules, the 5-liter concentrate is a permanently economical and effective component of the professional cleaning

Q²M Iron remains as a gel on the surface, thus extending the effective dwell time. The nearly neutral pH of 6 makes the product safe for clear coats, ceramic coatings, all types of rims, and glass – with a correct maximum dwell time of 2 minutes.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMandatory step before polishing and coating.\u003c\/strong\u003e Iron particles are in the clear coat, not on the clear coat. Polishing only displaces them, but does not remove them. Q²M Iron chemically dissolves the particles from the paint surface before you polish or apply a coating. Without this step, you seal the contamination under the coating – with the risk of long-term damage to the clear coat.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003ePractical Tip from Detailing1:\u003c\/strong\u003e GYEON specifies a maximum dwell time of 2 minutes – significantly shorter than many competitors. Stick to this. The active ingredient reaches its saturation limit after 2 minutes: longer dwell time does not provide additional cleaning performance, but increases the risk of residues on the surface. For heavy contamination, a second pass is always more effective than an extended dwell time on the first. Always apply to washed, wet paint – never to dry or hot surfaces, never in direct sunlight.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eSpray on. 2 Minutes. Rinse off.\u003c\/h3\u003e\n\u003cp\u003eGYEON Q²M Iron is sprayed onto the wet paint after pre-washing and reacts visibly with the iron particles on the surface within 30-60 seconds. You need about 150 ml per vehicle for moderate contamination – that's three to four complete vehicle cleanings from the 500 ml bottle.\u003c\/p\u003e\n\n\u003cp\u003eWork from top to bottom: roof, hood, side panels, then bumpers and sills. The lower areas are more contaminated because they are directly exposed to brake dust from the front axle. When the color change to violet begins, the reaction has started. After a maximum of 2 minutes, rinse off with a strong jet of water – do not wait longer.\u003c\/p\u003e\n\n\u003cp\u003eFor wheel arches and hard-to-reach areas on the sills, you can spread the product with a soft brush or applicator. Do not scrub – just spread. The chemical reaction does the work. For new cars delivered by rail, expect two passes: iron contamination from rail abrasion is significantly higher than from normal road traffic.\u003c\/p\u003e\n\n\u003cp\u003eOne detail that GYEON does not explicitly communicate: Q²M Iron must not be diluted with water. The reason is simple – tap water contains trace amounts of iron, and the active ingredient would react immediately with these traces instead of working on the paint surface. This is also why it is recommended to work on wet paint: the water on the paint is already applied and does not dilute the product, but helps to distribute it evenly.\u003c\/p\u003e\n\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/gyeon-q2m-iron-anwendung-farbumschlag.jpg?v=1776067914\" alt=\"GYEON Q²M Iron application with violet color change on black paint\" loading=\"lazy\" width=\"1200\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eIron rust dissolves Q²M Iron. Tar does not.\u003c\/h3\u003e\n\u003cp\u003eQ²M Iron reacts exclusively with iron compounds – brake dust, rail abrasion, industrial emissions. Organic contaminants such as tar, tree sap, insect residues, or bird droppings do not show a color change and are not dissolved. This is not a defect, but chemistry: thioglycolic acid binds iron, not carbon.\u003c\/p\u003e\n\n\u003cp\u003eThe color change is more than a visual effect – it is a diagnostic tool. Strong violet discoloration means high iron contamination. If an area remains colorless, there is no iron rust there, but possibly tar or organic dirt. This information helps you to choose the next cleaning step specifically: where Q²M Iron does not react, a \u003ca href=\"\/en\/products\/gyeon-q2m-tar-redefined-harzentferner-teerentferner\"\u003etar remover\u003c\/a\u003e based on solvents is needed.\u003c\/p\u003e\n\n\u003cp\u003eFor complete chemical decontamination, you therefore need two products: Q²M Iron for inorganic contamination (iron) and tar remover for organic (tar, resin, adhesive residues). The order is secondary – both products work on different types of contamination and do not affect each other. This is followed by mechanical decontamination with \u003ca href=\"\/en\/products\/gyeon-q2m-claylube-redefined-gleitmittel-reinigungsknete\"\u003ecleaning clay\u003c\/a\u003e for anything that has not been chemically dissolved.\u003c\/p\u003e\n\n\u003cp\u003eWhere Q²M Iron reaches its limits: For vehicles that have been in road traffic for longer than 6 months without decontamination, the iron particles have penetrated so deeply into the clear coat that even two passes will not dissolve everything. In this case, subsequent polishing helps to mechanically remove the remaining inclusions.\u003c\/p\u003e\n\n\u003cp\u003eQ²M Iron removes the free and surface-near particles – the deeply embedded ones are a job for the polishing machine. Even against burnt-on brake dust on rims that has eaten in for months, Q²M Iron, designed for the overall paint, is not the first choice – for this, there is the more concentrated Iron WheelCleaner.\u003c\/p\u003e\n\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/gyeon-q2m-iron-ergebnis-violette-reaktion.jpg?v=1776067919\" alt=\"GYEON Q²M Iron violet color change on paint surface as close-up\" loading=\"lazy\" width=\"1200\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eBefore every polish. Without exception.\u003c\/h3\u003e\n\u003cp\u003eQ²M Iron belongs in every detailing workflow between washing and polishing – whether for full detailing in the workshop or for thorough garage care on the weekend. The complete decontamination sequence: Wash, chemical decontamination (Iron + Tar), mechanical decontamination (clay), then polishing and coating. Those who skip this step polish iron particles into the clear coat instead of removing them.\u003c\/p\u003e\n\n\u003cp\u003eThe reason is physical: iron particles are harder than clear coat. When you drive a polishing machine over contaminated paint, the polishing pad presses the particles deeper into the material instead of abrading them. The result initially looks good because the polish smoothes the paint around the particles. But under the new surface, the iron inclusions remain – and continue to oxidize there for weeks. Q²M Iron before polishing is therefore not a recommendation, but damage prevention.\u003c\/p\u003e\n\n\u003cp\u003eQ²M Iron is also useful for regular care between detailing sessions: applied to washed paint every 2–3 months, it prevents the accumulation of iron particles and keeps the paint surface decontaminated. This is particularly important for vehicles with ceramic paint protection: the coating layer protects the clear coat, but iron particles also settle on the sealant and can attack it in the long term.\u003c\/p\u003e\n\n\u003cp\u003eAfter the Iron treatment, it is recommended to refresh the sealant – either wet with a wet sealant or dry with a spray coating. This is the complete care workflow in under 20 minutes: wash, Iron, rinse, seal. A typical sulfur smell during application is normal and indicates the active reaction of the active ingredient with the iron oxides – it dissipates completely after rinsing.\u003c\/p\u003e\n\n\u003cp\u003eThe three container sizes cover different application scenarios: 500 ml for 3–4 vehicles for regular washing, 1 liter as the standard size for the ambitious home user, 4 liters for detailers and workshops with several vehicles per week.\u003c\/p\u003e\n\n\u003cp\u003eAt approx. €6 per application (500 ml bottle, approx. 150 ml per vehicle), Q²M Iron is not a luxury product, but standard equipment for anyone who wants to preserve their paint long-term. If you want to lower the price per liter, opt for the 4-liter container size: €102 for 4,000 ml results in €25.50 per liter compared to €36 for the 500 ml bottle.

Tree sap contains terpenes and resin acids that cross-link with UV radiation and become increasingly harder over time. Mechanical removal without a suitable solvent inevitably causes scratches – the contamination is harder than the paint surface and would act like sandpaper.\u003c\/p\u003e\n\u003cp\u003eThe right product first chemically dissolves the contamination, reduces its adhesion, and then makes it accessible for mechanical blotting. GYEON Q²M Tar is formulated precisely for this – the solvent component penetrates the tar or resin layer, dissolves the bond to the paint surface, and enables gentle, scratch-free removal.\u003c\/p\u003e\n\n\u003ch3\u003eStep-by-step application\u003c\/h3\u003e\n\u003cp\u003eBefore treating with Q²M Tar, wash the vehicle normally to remove loose surface dirt. Leave the affected area dry or slightly damp – depending on product instructions. Spray Q²M Tar directly onto the contamination and let it dwell for 1 to 2 minutes. Dab with a clean, soft microfiber cloth, do not rub – this absorbs the dissolved contamination without spreading it on the surface.\u003c\/p\u003e\n\u003cp\u003eFor stubborn residues, repeat the process. Never apply excessive mechanical pressure – Q²M Tar is formulated so that patience and chemistry do the work, not brute force. After treatment, thoroughly rinse the area and clean with a shampoo to completely remove solvent residues.\u003c\/p\u003e\n\n\u003ch3\u003eQ²M Tar in the decontamination process\u003c\/h3\u003e\n\u003cp\u003eIn the professional decontamination workflow, Q²M Tar has a clear position: it follows regular washing and iron remover treatment, but specifically addresses organic contaminants that iron removers do not affect.

Not with correct application and thorough rinsing afterwards. The solvent component is chosen to dissolve tar and resin, but does not permanently attack cured SiO₂ layers. Nevertheless, always thoroughly wash coated surfaces after Tar treatment and, if possible, refresh with a quick detailer.\u003c\/p\u003e\n\u003cp\u003eFor very freshly applied coatings (within the first 48 hours), it's better to avoid Q²M Tar and work selectively with a neutral isopropanol-water mixture. For fully cured coatings, Q²M Tar can be used without hesitation.\u003c\/p\u003e\n\n\u003ch3\u003eQ²M Tar in the overall picture of paint care\u003c\/h3\u003e\n\u003cp\u003eTar and resin are often the invisible causes of paint problems that at first glance look like polishing errors or coating failures.

The product chemically loosens insect residues and road film, so that no mechanical pressure is necessary during the subsequent washing – this significantly reduces the risk of scratches during contact washing.\u003c\/p\u003e\n\n\u003cp\u003eSpray the product evenly onto the dry, cold surface – the front, bumper, windshield, mirrors, and A-pillars are typical insect zones. Work from bottom to top so that the product does not run off too quickly and the dwell time is evenly distributed.\u003c\/p\u003e\n\n\u003cp\u003eAfter 2–3 minutes, rinse off with a high-pressure cleaner or a strong jet of water from top to bottom. The dissolved insect residues flow away with the water without you having to touch the surface. Then wash normally with \u003ca href=\"\/en\/products\/gyeon-q2m-bathe-autoshampoo\"\u003ecar shampoo\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003cp\u003eImportant regarding timing: do not let it dwell for longer than 3 minutes. The surfactants in Bug\u0026amp;Grime are saturated after this time – a longer dwell time does not provide additional cleaning power but increases the risk of residue on the surface. This is especially true in summer at temperatures above 25 °C, when the product dries faster.\u003c\/p\u003e\n\n\u003cp\u003eFor stubborn, dried-on insect residues from days ago, a single pass will not remove everything. Apply a second pass and additionally agitate gently with a soft detailing brush. The brush distributes the product and brings fresh surfactants to the contamination – this is more effective than longer dwell time.\u003c\/p\u003e\n\n\u003cp\u003eFor spot treatment on the go, Bug\u0026amp;Grime also works without a high-pressure cleaner: spray directly onto the spot, let it dwell for 2–3 minutes, and gently dab it off with a damp microfiber cloth. Do not wipe over the insect residues, but dab off the softened material – this prevents scratches even without a water connection.\u003c\/p\u003e\n\n\u003cp\u003eAnother detail for use on glass: Bug\u0026amp;Grime works just as safely on windshields as on paint. Insects on the windshield are often a greater nuisance than on the hood because they impair visibility and wipers only smear the residues. Spray Bug\u0026amp;Grime onto the dry windshield, let it dwell, and rinse off – afterward, the windshield wipers will wipe streak-free again.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/anwendung-bug-grime.jpg?v=1776026163\" alt=\"GYEON Q2M Bug Grime being sprayed onto an insect-contaminated vehicle front\" loading=\"lazy\" width=\"1200\" height=\"800\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eHe removes insects. Not insect etchings.\u003c\/h3\u003e\n\u003cp\u003eBug\u0026amp;Grime reliably removes fresh and dried insect residues from the paint surface – that is its core competence. In addition, the cleaner removes road film, light tar splashes, and the typical summer film of pollen and dust on hoods and windshields.\u003c\/p\u003e\n\n\u003cp\u003eFirst limitation: insect etchings in the clear coat. If insect residues remain on the paint for days in the sun, the acids they contain chemically etch the clear coat. These etchings are physical damage to the paint surface – no cleaner can remove them.\u003c\/p\u003e\n\n\u003cp\u003eFor this, you need a paint polish to abrade the damaged clear coat layer and expose a fresh layer. Bug\u0026amp;Grime prevents such etchings by removing insect residues in time. If you clean within 24 hours after every highway drive, you will generally not find any etchings.\u003c\/p\u003e\n\n\u003cp\u003eIf you only act after a week, you have to expect paint damage – especially on dark vehicles that heat up more in the sun. Dark paint absorbs more heat, insect acids react faster, and etchings become deeper. Here, quick action is the best paint protection – a 500 ml bottle in the trunk costs €13 and can prevent polishing costs of €200 and more.\u003c\/p\u003e\n\n\u003cp\u003eSecond limitation: tar and tree sap. Bug\u0026amp;Grime is formulated for protein-based contaminations (insects, bird droppings, biofilm). Hydrocarbon contaminations such as tar, bitumen, and tree sap do not react to alkaline surfactants – for that, \u003ca href=\"\/en\/products\/gyeon-q2m-tar-redefined-harzentferner-teerentferner\"\u003eQ²M Tar\u003c\/a\u003e is the right product.

As a pre-wash before every summer wash, the insect remover significantly reduces the risk of scratches. Particularly relevant for vehicles with ceramic coating or fresh polish, where every micro-scratch becomes visible.\u003c\/p\u003e\n\n\u003cp\u003eIn the Detailing1 washing workflow, Bug\u0026amp;Grime comes first: Bug\u0026amp;Grime on the front → \u003ca href=\"\/en\/products\/gyeon-q2m-foam-schaumreiniger\"\u003eQ²M Foam\u003c\/a\u003e as pre-foam on the entire vehicle → main wash with Q²M Bathe or Q²M Bathe+ → optionally Q²M WetCoat as a wet sealant. Four steps, under 30 minutes, the front is clean without a single scratch.\u003c\/p\u003e\n\n\u003cp\u003eBug\u0026amp;Grime takes on the most difficult task in the workflow: dissolving protein-bound contaminations that the foam cleaner alone fails to address. Foam softens superficial dust and road grime, but dried insect proteins require the higher pH value of a dedicated insect remover. The difference is measurable: after a pre-wash with Bug\u0026amp;Grime, the wash mitt glides over the front without resistance during contact washing – without Bug\u0026amp;Grime, you feel every dried insect residue as resistance under the mitt.\u003c\/p\u003e\n\n\u003cp\u003eBug\u0026amp;Grime is less suitable as a replacement for a complete pre-cleaner. If you want to free the entire vehicle from road grime, it's better to use Q²M Foam as a pre-foam – it covers all surfaces and dissolves general dirt more efficiently than an insect remover. Bug\u0026amp;Grime remains the special tool for the front and all areas with insect infestation.\u003c\/p\u003e\n\n\u003cp\u003eIf you only occasionally remove insects and don't need a regular workflow: the 500 ml spray bottle fits in any driver's door and is ready for immediate use as a spot treatment. Spray directly onto the front after a highway drive, let it dwell, and rinse off at the nearest self-service car wash.\u003c\/p\u003e\n\n\u003cp\u003eThis is the simplest insurance against insect etchings in summer. For year-round use or multiple vehicles, the 4-liter canister is worthwhile: same formula, lower liter price of €15.50 per liter instead of €26 for the 500 ml bottle.

The product pH is around 2 and is formulated with lubricating oil carriers that prevent marring on the paint surface during application.\u003c\/p\u003e\n\n\u003cp\u003eThis approach fundamentally distinguishes Q²M WaterSpot from mechanical polishing. Limescale spots are removed purely chemically, without paint removal, without holograms, and without risk to thin clear coat layers. This is particularly important on OEM paints, where the clear coat layer is often only 40 to 60 µm thick and any polishing means measurable material removal. The oil component in the product is no coincidence, but a protective function: it encapsulates the dissolved mineral particles and prevents the acid solution itself from leaving micro-scratches when wiping.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_gyeon-q2m-waterspot-kalkfleckenentferner_hero.jpg?v=1776548035\" alt=\"GYEON Q²M WaterSpot spray bottle in front of vehicle with limescale spots on paint\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAcidic phosphoric acid active formula on paint and glass.\u003c\/strong\u003e The product pH of around 2 chemically dissolves calcium carbonate within 30 seconds.

The lubricating oil component dries in seconds, and you wipe off oil streaks instead of dissolved limescale. Always work in the shade, at a paint temperature below 25 °C, and never leave the product on for longer than 30 seconds. After wiping, follow with a second pass with an alcohol degreaser or pH-neutral wash to remove oil components — otherwise, you'll create a dirt-attracting surface.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eCool paint. 30 seconds. No longer.\u003c\/h3\u003e\n\u003cp\u003eOn warm paint or in direct sunlight, the lubricating oil component dries in seconds, and you wipe off oil streaks instead of dissolved limescale. Q²M WaterSpot requires a washed, dried, and cool surface — then the acid reaction starts evenly. Spray directly onto the limescale spots from a distance of about 15 to 20 centimeters, one to two sprays per panel (about 15 ml).\u003c\/p\u003e\n\n\u003cp\u003eThe maximum dwell time is 30 seconds, not a second longer. Then wipe off with a soft, clean microfiber cloth in one direction. A common misconception in practice is the idea that longer dwell time would better dissolve stubborn spots. The opposite is true: after 45 seconds, the phosphoric acid solution begins to dry, and the lubricating oil component no longer wipes off evenly.\u003c\/p\u003e\n\n\u003cp\u003eFor stubborn or slightly dried water spots, work in two passes: wipe off the first application after 30 seconds, then immediately spray a second layer on the same spot and wipe off after 30 seconds as well. The second pass takes place on the chemically pre-treated surface and dissolves residues that the first pass did not catch.\u003c\/p\u003e\n\n\u003cp\u003eFinally, rinse the treated area with clear water or wipe with a second microfiber cloth and some shampoo water. This post-cleaning is not optional, but an integral part of the workflow: Q²M WaterSpot leaves a thin oil film that attracts dust and pollen until it is washed off. For larger applications on multiple panels, direct transition to a full wash in our \u003ca href=\"\/en\/collections\/vorreiniger\"\u003epre-cleaner\u003c\/a\u003e category is worthwhile; for targeted stain removal, a damp second wipe is sufficient.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_gyeon-q2m-waterspot-kalkfleckenentferner_anwendung.jpg?v=1776548038\" alt=\"GYEON Q²M WaterSpot application on cool paint with microfiber cloth\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003ePhosphoric acid dissolves limescale. Waxes, unfortunately, too.\u003c\/h3\u003e\n\u003cp\u003eAnyone who maintains their vehicle with carnauba wax or spray wax loses their own protective layer with every WaterSpot application — the acidic pH of about 2 attacks every organic sealant. However, the product works reliably on evaporated hard and rainwater, chemically converting calcium and magnesium carbonates into water-soluble salts that can be wiped off the paint in one pass.\u003c\/p\u003e\n\n\u003cp\u003eThis is the real dividing line for the purchase decision. Silicate-based ceramic coatings from GYEON are chemically so stable that they can withstand contact with phosphoric acid at pH 2 for 30 seconds without damage — this is one of the advantages for which the coating was originally installed. Carnauba wax layers, synthetic sealants, and hybrid wax coatings cannot withstand this stress and are partially or completely dissolved.\u003c\/p\u003e\n\n\u003cp\u003eThe result is not paint damage, but a rebuilding of the protective layer. If you maintain your vehicle with a spray wax every three months, every WaterSpot application means: water spots gone, wax layer gone, reapply wax. This step is omitted with active ceramic coatings because the coating remains.\u003c\/p\u003e\n\n\u003cp\u003eThe clear limits: Burnt-in limescale spots after months of neglect are often no longer completely soluble chemically — calcium has worked its way into the clear coat there, and only a light finish polish will remove the rest. WaterSpot is considered safe for glass surfaces; for hardened water spots on the windshield, a specialized \u003ca href=\"\/en\/products\/gyeon-q2m-glass-plus-glasreiniger-versiegelung\"\u003eglass cleaner with sealant\u003c\/a\u003e or a glass polish is the cleaner tool.

Especially the south, Franconia, and large parts of Saxony-Anhalt with water hardness above 14 °dH produce these traces: the hydrophobic layer beads water, but does not always let it drain completely, and residual water dries at the lowest point of a drop. Q²M WaterSpot is the routine that stops these traces before they can only be polished out.\u003c\/p\u003e\n\n\u003cp\u003eThe product is also useful for anyone who lets their car dry outside after washing due to lack of a garage. If residual water evaporates in the sun, characteristic water spots remain that can no longer be removed with shampoo. Here, WaterSpot provides the chemical solution for which one would otherwise have to use polishing paste.\u003c\/p\u003e\n\n\u003cp\u003eWaterSpot is less suitable for care profiles with carnauba wax, spray waxes, or hybrid sealants as the primary protective layer. In this setup, each application dissolves the protective layer itself — the opposite of what one uses a wax for. For these users, a detailing clay is a better choice. The product is also unsuitable for freshly applied coatings: before the 7-day curing phase has expired, the coating can be partially damaged.\u003c\/p\u003e\n\n\u003cp\u003eRegarding the choice of container size: The 500 ml bottle is sufficient for about 30 applications with targeted use — the right start for private ceramic detailers with one to two vehicles. The 1-liter bottle pays off from the second vehicle or for commercial detailing. Store frost-free between 5 and 30 °C, durable for 24 months after opening.\u003c\/p\u003e\n\n\u003cp\u003eThe strongest lever from Detailing1 practice is the sequence — and most people do it wrong.

Q²M ClayLube is formulated for precisely this application: maximum lubricating effect, minimal residues, optimal claying temperature.\u003c\/p\u003e\n\n\u003ch3\u003eWhen should paint clay with Q²M ClayLube be used?\u003c\/h3\u003e\n\u003cp\u003eThe rule of thumb: After every complete vehicle detailing (1–2 times annually) and whenever the paint feels rough (the \"sandwich bag test\" – rough = contaminated). Typical indications are: after winter (road salt, brake dust), after stays near industrial plants (industrial fallout), before preparation or coating application.

Normal car shampoo can serve as a makeshift solution but has several disadvantages compared to Q²M ClayLube: It dries faster (less working time), does not form as uniform a lubricating film, and often leaves more residue. Q²M ClayLube is optimized for specific use with paint clay and delivers consistently better results – fewer scratches, cleaner surface, more pleasant work process. The investment in a good lubricant is more than justified given the risk of scratches from improper claying.\u003c\/p\u003e\n\n\u003ch3\u003eQ²M ClayLube in the complete decontamination workflow\u003c\/h3\u003e\n\u003cp\u003eIn professional detailing, Q²M ClayLube is an integral part of the decontamination step.

The result: a crystal-clear, absolutely clean paint surface that offers optimal adhesion for coatings and polishes. Without this step, coatings would adhere to contaminants – with all the negative consequences for durability and appearance.\u003c\/p\u003e\n\n\u003ch3\u003ePurchase Recommendation: Q²M ClayLube for complete paint preparation\u003c\/h3\u003e\n\u003cp\u003eGYEON Q²M ClayLube is an indispensable tool for any thorough vehicle detailing.

As soon as the active ingredient comes into contact with the ice, the ice begins to melt – the chemical reaction starts immediately and proceeds without external heat. The resulting film of water is removed by the wiper. At the same time, DeFrost leaves a thin protective film on the window that delays refreezing due to its lower freezing point temperature – a double protective function in one product.\u003c\/p\u003e\n\n\u003ch3\u003eDeFrost for All Vehicle Areas in Winter\u003c\/h3\u003e\n\u003cp\u003eQ²M DeFrost is primarily developed for windows but also works on other iced-over vehicle parts: door locks and door seals (no freezing), mirror glass, camera lenses and sensor covers, as well as door handles and trunk lids.
