An acid-free, viscous wheel cleaner from Koch-Chemie's workshop line that visibly dissolves brake dust and flash rust chemically via a red-violet colour change. Works on alloy painted, alloy polished, chrome and steel. Not for baked-on tar or bitumen spots.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp id=\"speakable-definition\"\u003e\u003cstrong\u003eThe Koch-Chemie Magic Wheel Cleaner\u003c\/strong\u003e — usually just called \"MWC\" in-house — is an acid-free wheel cleaner from Koch-Chemie's workshop line. The active ingredient ammonium mercaptoacetate, a salt of thioglycolic acid, reacts with the iron(III) compounds in brake dust and lifts them off the wheel surface as a red-violet complex. The colour change isn't a marketing gimmick but the chemical reaction itself: where you see violet, iron is being converted right then and there. With a pH of 5–6 the formula stays gentle on painted and polished alloy wheels, chrome and steel. The high viscosity of 50 mPa·s means the product clings to vertical wheel faces instead of running straight off — so you get the full dwell time on the surface.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRed-violet colour change as a reaction indicator.\u003c\/strong\u003e No guessing how long to wait. You see in real time where iron particles are reacting and when the reaction is done. That kills two classic mistakes: rinsing too early (cleaning unfinished) and leaving it on too long (product saturates and dries on).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSyrup-like viscosity for vertical cling.\u003c\/strong\u003e At 50 mPa·s the Magic Wheel Cleaner is thick enough to stay in the spokes and on the wheel flank without dripping straight to the ground. That sets it apart from watery wheel cleaners where half the product would run off unused.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOne cleaner for your whole wheel collection.\u003c\/strong\u003e Alloy painted, alloy polished, chrome and steel — the pH of 5–6 is mild enough to use even on high-gloss polished forged wheels. On anodised or matte-coated wheels, test on a hidden spot first.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDay-to-day from Detailing1:\u003c\/strong\u003e Always spray onto a cold, dry wheel — never in direct sun, never onto warm brakes after a drive. Warm surfaces let the gel dry on, and that leaves residue you then have to brush off. On heavily soiled wheels after months without cleaning, two short passes beat one long one: the active ingredient is chemically saturated after about 5 minutes. Just let it dwell twice for 3 minutes each and rinse in between.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eCold wheel. Spray. Wait 2 to 5 minutes.\u003c\/h3\u003e\n\u003cp\u003eSpray the Magic Wheel Cleaner onto the cold, dry wheel — cover spokes, barrel, the rim edge and the wheel bolts evenly. Thanks to the syrup-like consistency the product clings vertically without you having to change how you work. Best to work bottom to top so you don't cover faces you've already wetted.\u003c\/p\u003e\n\n\u003cp\u003eAfter 30 to 60 seconds the colour change kicks in: first on spots with a lot of brake dust, then across the whole face. Red-violet streaks show you exactly where iron particles are being converted. After 2 to 5 minutes' dwell time the reaction is done — waiting longer gets you nothing, because the active ingredient is saturated after about 5 minutes. A common mistake is leaving the product on for 10 minutes hoping for better results. The opposite happens: the solution starts to dry on and leaves streaks.\u003c\/p\u003e\n\n\u003cp\u003eFinish by rinsing off with a strong jet of water from the pressure washer or garden hose, top to bottom. With heavy brake dust between tight spokes a \u003ca href=\"\/en\/collections\/zubehoer-felgenpflege\"\u003ewheel brush\u003c\/a\u003e can help spread the dissolved material — but not for scrubbing, just for touch-up. If you clean weekly to fortnightly, one pass usually does the job.\u003c\/p\u003e\n\n\u003cp\u003eA note on dosing: 500 ml lasts for about 10 full vehicle cleans. Per wheel, 40 to 50 ml is plenty. That works out to EUR 1.25 per full application — far more economical than the bottle price suggests, once you weigh it against the time spent mechanically scrubbing with less effective cleaners.\u003c\/p\u003e\n\n\u003ch3\u003eIt dissolves iron particles. Not tar.\u003c\/h3\u003e\n\u003cp\u003eThe Magic Wheel Cleaner is built precisely for one job: dissolving brake dust and flash rust chemically. The reaction between ammonium mercaptoacetate and the iron(III) ions in brake dust is the mechanism — anything that isn't iron doesn't get touched. That explains the colour change as a diagnostic tool: no colour means no iron, and no effect in that case isn't a shortfall of the product but the right answer to the dirt.\u003c\/p\u003e\n\n\u003cp\u003eAs a secondary use, the Magic Wheel Cleaner also works on paint as a flash-rust remover — especially handy on vehicles parked under industrial fallout or next to railway tracks. Fine iron particles settle there on the clear coat and react with the MWC formula just like they do on the wheel. Used before polishing, it boosts the adhesion of any following wax or ceramic coating, because the paint surface is genuinely contamination-free.\u003c\/p\u003e\n\n\u003cp\u003eWhere the MWC isn't the right product: baked-on tar, bitumen spots and oily soiling don't react with thioglycolate salts. For that you need a solvent-based tar remover. On badly neglected wheels with months-old brake dust that has worked its way into the pores, the stronger \u003ca href=\"\/en\/products\/koch-chemie-reactive-wheel-cleaner-rwc\"\u003eKoch-Chemie Reactive Wheel Cleaner\u003c\/a\u003e can be the better call — its acid system is more powerful, though not suited to every wheel material. The choice is clear: when safety on chrome and polished wheels matters, MWC. When you need maximum cleaning power and you're working with alloy painted and steel, RWC.\u003c\/p\u003e\n\n\u003cp\u003eA second case where no wheel cleaner in the world will help anymore: when the wheel is already visibly corroded or the clear coat has flaked off. At that point cleaning isn't the issue anymore — paint refurbishment is. The Magic Wheel Cleaner is a care product, not a restoration product.\u003c\/p\u003e\n\n\u003ch3\u003eYour standard for the regular wheel workflow\u003c\/h3\u003e\n\u003cp\u003eThe Magic Wheel Cleaner is the right call for anyone who keeps their wheels on a regular schedule and wants a product where they don't have to think about material compatibility. One product, one step, all wheels done. That's workshop logic — and that's exactly what the MWC is formulated for.\u003c\/p\u003e\n\n\u003cp\u003eIt really plays its strengths when you look after several vehicles with different wheel types or work on a fleet. Instead of three cleaners for three wheel types, one does it. It's weaker on extremely baked-on brake-dust residue from high-performance brake setups, or on wheels that haven't been cleaned for months. In both cases a second pass or a more aggressive product makes more sense than extending the dwell time.\u003c\/p\u003e\n\n\u003cp\u003eAs a complete solution the Magic Wheel Cleaner works best paired with a \u003ca href=\"\/en\/collections\/vorreinigung\"\u003epre-cleaner\u003c\/a\u003e like Koch-Chemie Vorreiniger B, applied as foam over the whole wheel before the MWC goes into the spokes. Finish with a \u003ca href=\"\/en\/collections\/reifenpflege\"\u003etyre dressing\u003c\/a\u003e on the flank — and the complete wheel workflow comes in at around 15 minutes per vehicle, if you stay on it every two weeks. That's the most common combo our customers buy: Vorreiniger B + Magic Wheel Cleaner. A precise, repeatable routine that works without scrubbing.\u003c\/p\u003e\n\n\u003cp\u003eHead to head with the acid-free classic SONAX FelgenBeast, the Magic Wheel Cleaner comes out ahead on two counts: the higher viscosity means longer contact time on the wheel, and the workshop formula is dosed stronger for commercial use. The FelgenBeast has a milder smell, though — if you work in a closed garage you'll definitely notice that. The Magic Wheel Cleaner is the workshop standard. The FelgenBeast is the garage all-rounder. Both do their job reliably; the question is which one fits your working environment.\u003c\/p\u003e","brand":"Koch-Chemie","offers":[{"title":"500ml","offer_id":48503670374735,"sku":"D1-KCX-425500","price":13.49,"currency_code":"EUR","in_stock":true},{"title":"2x 500ml","offer_id":49725159276879,"sku":"D1-KCX-425500_2","price":29.38,"currency_code":"EUR","in_stock":true},{"title":"3x 500ml","offer_id":49725159342415,"sku":"D1-KCX-425500_3","price":43.62,"currency_code":"EUR","in_stock":true},{"title":"10 liters","offer_id":48503670407503,"sku":"D1-KCX-425010","price":123.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-magic-wheel-cleaner-saeurefreier-felgenreiniger.jpg?v=1776410618"},{"product_id":"koch-chemie-motorplast-mp-motorkonservierung","title":"Motorplast \"Mp\" Engine Preservation","description":"\u003ch2 id=\"speakable-headline\"\u003ePreserve the engine bay instead of just sprucing it up for a minute\u003c\/h2\u003e\n\n\u003cblockquote id=\"speakable-summary\"\u003e\n  \u003cp\u003e\u003cem\u003eWhat is Koch-Chemie Motorplast?

You spray it on as a pump mist over the pre-cleaned, still-wet engine bay, where it pushes out the residual water and cross-links after 6 to 8 hours into a dirt-repellent, wafer-thin layer. Unlike classic engine-shine sprays, Motorplast skips propellants and silicone, which is what clears it for use in body shops (no painter's fisheyes) and on Mercedes-Maybach models (official factory approval).\u003c\/p\u003e\n\n\u003cp\u003eThe look stays deliberately satin-matt rather than high-gloss — the surface keeps its original character, the protection is physically there without the engine looking like it has just been oiled up.

Lay down puddles instead of a fine mist and you stretch the drying time well past the usual 6 to 8 hours, the polymer cures unevenly and leaves milky edges or tacky spots. The clean routine: let the engine cool to hand-warm, pre-clean with \u003ca href=\"\/en\/products\/koch-chemie-green-star-gs-universalreiniger\"\u003eGreen Star\u003c\/a\u003e at 1:10, rinse off with a soft water jet, mist Motorplast thinly into the still-wet bay, close the bonnet and let it sit overnight. Tap any leftover pools the next morning with a dry microfibre cloth. It's self-levelling — no working in with a pad needed.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eSpray it on wet. Bonnet shut. Dry overnight.\u003c\/h3\u003e\n\n\u003cp\u003eYou spray Motorplast onto the pre-cleaned, still-wet engine bay because the residual water carries the polymers right into the tight gaps before the product itself pushes it back out. That's pro technique straight from the Daimler factory-norm test, not a marketing slogan.\u003c\/p\u003e\n\n\u003cp\u003eBefore you apply, let the engine cool down — hand-warm is ideal, boiling hot is not. On a block sitting at 130 °C oil temperature after a motorway run, the water-glycol-ether mix flashes off instantly and burns the polymers into the plastic as streaks. The officially approved heat window is 250 °C component temperature — that's for the cured film, not for the moment you apply it.\u003c\/p\u003e\n\n\u003cp\u003eFor a mid-size car, reckon on 50 to 200 ml. Work sparingly from about 20 cm away with the spray head and go systematically from back to front — valve cover, fuse box, then intake manifold, then the visible hoses and seals. You can reach awkward spots with a Cyclone or Tornador gun at 4 to 6 bar; in the home garage the supplied spray head does the job. Keep the mist away from open intake tracts and mass airflow sensors — those hot-wire sensors react badly to polymer coatings.\u003c\/p\u003e\n\n\u003cp\u003eOnce it's on, close the bonnet and let it sit 6 to 8 hours, ideally overnight. Day-one test: check the next morning whether any pools or drips are still holding. If so, tap them with a dry microfibre cloth — don't rub. The film is self-levelling and needs no mechanical spreading.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-motorplast-mp-motorkonservierung_anwendung.png?v=1777464474\" alt=\"Koch-Chemie Motorplast Mp being sprayed onto a wet engine bay Detailing1\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003ePlastic, rubber, ancillaries. Never the drive belt.\u003c\/h3\u003e\n\n\u003cp\u003eMotorplast is approved for the typical engine-bay materials: PA, PP and ABS plastic covers, EPDM rubber hoses, seals and metal ancillaries in aluminium or steel. On these substrates the permanently elastic polymer film forms, holding off dirt build-up by months and slowing road-salt corrosion.\u003c\/p\u003e\n\n\u003cp\u003eThe hard limits are friction- and safety-critical. Drive belts, V-belts and pulleys are off-limits — the polymer layer cuts the grip friction, the belt slips and worst case the alternator drops out. For the same reason, keep it off brake components, brake disc faces and the pedals. On body paint, overspray leaves streaks and is pointless there anyway — Motorplast is no paint sealant. Any mist that lands on an inner wing or bumper edge, wipe it off straight away with a damp microfibre.\u003c\/p\u003e\n\n\u003cp\u003eIf too much product did end up in the bay and milky streaks have formed, a stripping routine with an alkaline cleaner sorts it: spray \u003ca href=\"\/en\/products\/koch-chemie-green-star-gs-universalreiniger\"\u003eGreen Star\u003c\/a\u003e on generously at 1:10, foam it up with a soft detailing brush, rinse off. The cross-linked polymers break down under the APC and the film comes off without residue. After that you can lay on a second, thinner coat of Motorplast.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-motorplast-mp-motorkonservierung_detail.png?v=1777464492\" alt=\"Koch-Chemie Motorplast Mp permanently elastic protective film on a plastic cover\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eSpring and autumn. Twice a year is plenty.\u003c\/h3\u003e\n\n\u003cp\u003eThe typical rhythm for Motorplast is twice a year — once in spring after the salt season and once in autumn before winter sets in. In between, dusting the plastic covers with a microfibre cloth is enough. Detailing shops slot the product into their winter-check packages, because 5 minutes of work buys 6 months of corrosion protection.\u003c\/p\u003e\n\n\u003cp\u003eThe 500 ml spray bottle is the right call for a single car or for hobbyists getting seasonal vehicles like convertibles or classics ready for spring. Per treatment 50 to 100 ml — so the bottle carries you across several seasonal cycles. For multi-car households or commercial detailers the 5 litre canister pays off: noticeably lower price per litre, just decant it into a separate \u003ca href=\"\/en\/collections\/koch-chemie\"\u003eKoch-Chemie\u003c\/a\u003e cylinder bottle with a spray head. 20 and 200 litre containers are pure industrial variants for workshop groups and OEM supplier chains.\u003c\/p\u003e\n\n\u003cp\u003eStorage is fussier than with many other detailing products: Motorplast keeps at +5 °C to +25 °C, frost-free and out of the sun. Frost breaks down the polymer emulsion and the product won't spray cleanly afterwards. It's fine in the garage or the stockroom — just don't let it overwinter in the boot.\u003c\/p\u003e\n\n\u003cp\u003eApply Motorplast properly once — cold engine bay, wet pre-clean, thin mist, bonnet shut overnight — and you get an engine bay that looks the same after winter as it did before. That's the Detailing1 standard: not shine in the shop window, but an engine that still runs like new after three winters.

Spray straight onto the glass towel, not the panel, so you don't fling drops onto the dashboard or door card. Neat is also the move for the inside of the windshield, where outgassed plastics build a paper-thin film that diluted mix only half-dissolves. You spot that layer by the streaky glare in backlight even after you've just cleaned.\u003c\/p\u003e\n\n\u003cp\u003eDilution mistake we see often: concentrate first into the empty bottle, then water — that order builds a foam crown you'll be rinsing for minutes.

So Glas Star handles both inside and outside glass — most interior-only cleaners can't say the same.\u003c\/p\u003e\n\n\u003cp\u003eOn the inside of the rear screen, most cleaners struggle because the embedded heating elements act like edges. Glas Star runs smoothly over the wires thanks to the glide aid and won't streak there — as long as you wipe in one direction with a \u003ca href=\"\/en\/products\/koch-chemie-pro-glass-towel-230gsm-mikrofaser-glastuch\"\u003eglass-specific microfibre\u003c\/a\u003e, not in circles.

Cut to at least 1:3 and keep clear of the edges. On anti-fog coated interior glass (some OEM windshields from 2020 onward), neat Glas Star can streak — patch-test on a 5×5 cm spot first.

Mobile detailers and shops almost always grab the 10 or 20-liter variant. Versus ready-to-use 750 ml spray bottles, you save around 80% in packaging and 60% in cost for the same number of applications.\u003c\/p\u003e\n\n\u003cp\u003eFor private use, the 1-liter bottle usually rides three to five years. Mix once, store the spray bottle frost-free in the garage, and your interior cleans for the next season are queued up. The variant with the spray-head set is the easy-entry option — concentrate plus a matching HDPE spray bottle with a Canyon spray head in one order, no separate sourcing needed.\u003c\/p\u003e\n\n\u003cp\u003eIn the Detailing1 workflow, Glas Star follows the \u003ca href=\"\/en\/collections\/glasreiniger\"\u003ewheel and paint cleaning block\u003c\/a\u003e, otherwise the overspray from other cleaners lands back on the freshly cleaned glass. Inside, the windshield gets done last — after cockpit and dash have been dusted with microfibre — otherwise loose particles ride the air current and you're starting over.

With fresh air on, the blower pulls dust out of the engine bay onto the glass while you're wiping — streaks are basically guaranteed.\u003c\/p\u003e\n\n\u003cp\u003ePros also flip the sun visors down, because an astonishing amount of spray ends up on them. When you're done and drive off, it runs back onto the freshly cleaned screen as drops. Neither trick lives in any data sheet, but they're the difference between \"okay clean\" and \"looks like a fresh hand-over.\"\u003c\/p\u003e\n\n\u003cp\u003eIf you work with the concentrate regularly, after a few months you build your own system: one dedicated spray bottle at one fixed ratio, a glass-only towel that never touches cockpit or paint, and a second towel for the dry-off. That separation stops silicone-oil residue from cockpit care creeping over the towel onto the next window, where it leaves the half-moon streaks that even a second clean barely takes off.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-glas-star-gla-glasreiniger-konzentrat_lineup.png?v=1776205730\" alt=\"Koch-Chemie Glas Star Glass Cleaner Concentrate lineup — 1L, 10L, and 1L with Canyon spray head\" loading=\"lazy\"\u003e","brand":"Koch-Chemie","offers":[{"title":"1000 ml \/ 1 liter","offer_id":48463561163087,"sku":"D1-KCX-44001","price":7.99,"currency_code":"EUR","in_stock":true},{"title":"1000ml + Canyon spray head CHS-3AN","offer_id":49154922414415,"sku":"D1-KCX-39104+CHS-3AN","price":12.98,"currency_code":"EUR","in_stock":true},{"title":"1000ml + Canyon Spray Head CHS-3AN + HDPE Cylinder Bottle","offer_id":49154922447183,"sku":"D1-KCX-39104+CHS-3AN+HDPE","price":16.97,"currency_code":"EUR","in_stock":true},{"title":"10 liters","offer_id":48463564079439,"sku":"D1-KCX-44010","price":56.99,"currency_code":"EUR","in_stock":true},{"title":"20 liters","offer_id":49602860613967,"sku":"D1-KCX-44020","price":97.49,"currency_code":"EUR","in_stock":true},{"title":"200 liters","offer_id":49602860646735,"sku":"D1-KCX-44200","price":982.99,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-glas-star-premium-glasreinigerkonzentrat.jpg?v=1710623027"},{"product_id":"koch-chemie-kcu-reifenschaum-reifenpflege-600ml","title":"Koch-Chemie Kcu Tyre Foam \"Rfs\" Tyre Care","description":"\u003ch2\u003e\u003cstrong\u003eKoch-Chemie Kcu Tyre Foam \"Rfs\" — Tyre Care\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe \u003cstrong\u003eKoch-Chemie Kcu Tyre Foam\u003c\/strong\u003e is the easy way to sort your tyre care fast.

Hot brake discs radiate well past 200 °C — if the cleaner hits that heat, the water in the dilution flashes off in seconds and you're left with highly concentrated potassium hydroxide standing on the paint, eating into the clear coat. Wait at least 15 minutes after parking up and wet it down generously.\u003c\/p\u003e\n\n\u003cp\u003eThe dilution follows the level of dirt: 1:10 is enough for weekly upkeep, 1:5 is the all-round figure for normal brake dust after two to four weeks of driving, 1:2 stays reserved for the extreme crusts on workshop vehicles. A pump sprayer with a foam nozzle like the \u003ca href=\"\/en\/products\/koch-chemie-foamer-bottle-schaumspender-150ml\"\u003eKoch-Chemie Foamer Bottle\u003c\/a\u003e or an iK Foam sprayer lays the solution down as a sticky wet foam that clings to the barrel and doesn't run off.

Longer does nothing: Awh isn't about reaction time, it's about chemistry. Leave it on too long and all you risk is drying-in, and dry edges on the clear coat are the result. If a spot isn't clean, top up the dose — don't let it dwell longer.\u003c\/p\u003e\n\n\u003cp\u003eFinish with a strong pressure jet top to bottom. Rinse the barrel and the spoke edges in a controlled way until no foamy veil runs off any more. Cold rinse water is a must: warm water speeds up drying-in inside the barrel, and a leftover cleaner film later pulls into the clear coat as a run mark. On the tyre sidewalls you can put the Awh straight to use — it lifts the brown antioxidant bloom (tyre-rubber blooming) at the same time and saves you the separate tyre cleaner.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-alkali-wheel-cleaner-awh-felgenreiniger-alkalisch_anwendung.png?v=1778768219\" alt=\"Daniel spraying Koch-Chemie Alkali Wheel Cleaner Awh 1:5 from the iK Foam Pro 2 Alk onto the wheel barrel\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eSteel and painted aluminium yes, polished wheels no\u003c\/h3\u003e\n\n\u003cp\u003eAwh is cleared for standard steel wheels and alkali-resistant painted or powder-coated OEM aluminium wheels.

On these surfaces the potassium hydroxide reacts with the metal in seconds. It oxidises the surface and leaves a milky, deeply etched patch — what's known as alkali burn.\u003c\/p\u003e\n\n\u003cp\u003eThis damage can't be washed off. The wheel is only saveable with hours of machine polishing at a specialist shop, and that runs into several hundred euros fast. In plain terms: on expensive multi-piece BBS RS wheels, on Porsche Fuchs wheels, on uncoated OZ forged wheels and on chrome lips, the sprayer stays in your hand. If you're not sure whether the wheel is anodised or painted, ask the manufacturer or test on an inconspicuous spot.\u003c\/p\u003e\n\n\u003cp\u003eFor exactly these sensitive wheel types, the pH-neutral \u003ca href=\"\/en\/products\/koch-chemie-magic-wheel-cleaner-mwc-felgenreiniger\"\u003eMagic Wheel Cleaner \"Mwc\"\u003c\/a\u003e or the reactive \u003ca href=\"\/en\/products\/koch-chemie-reactive-wheel-cleaner-felgenreiniger-750ml\"\u003eReactive Wheel Cleaner\u003c\/a\u003e is the right call.

Laid down dry, the acid reacts too fast and bites into the surface harder than it needs to. A water pre-wet slows the reaction and spreads the concentrate evenly. The second common mistake: leaving it on too long. At pH -0.2, 30 to 90 seconds is plenty — after that the product belongs blasted off with a pressure washer. Letting it dry on causes material damage, not \"a little longer for more cleaning\".\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003ePre-wet, dilute 1:5, 60 seconds, rinse off\u003c\/h3\u003e\n\u003cp\u003eYou don't run the Fe neat. Standard dilution is 1:5 with water, up to 1:2 for extreme grime, up to 1:10 for light grime. That turns 11 kg of concentrate into 33 to 110 kg of working solution — one litre of ready solution costs between 0.72 and 2.40 EUR depending on the dilution.\u003c\/p\u003e\n\n\u003cp\u003eBefore you lay it down, hose the wheel down thoroughly with water. This pre-wet isn't optional. It slows the acid reaction, spreads the concentrate better and cuts the risk of streaking and spot material damage. Apply it with a low-pressure sprayer or brush from the bottom up, so run-off marks don't dry on. On vertical surfaces like wash-bay tiles, work in 1-metre lanes so the concentrate doesn't run over areas you've already done.\u003c\/p\u003e\n\n\u003cp\u003eThe order matters around the tyre. First mask the tyre sidewall or apply the dilution precisely — hydrochloric acid can bleach tyre markings. Then work the wheel itself, always from the same rotation position so no area gets missed. After rinsing, check it visually and only go for a second pass if there's grime still showing — with a properly dosed first pass that's rarely needed.\u003c\/p\u003e\n\n\u003cp\u003eDwell time is 30 to 90 seconds. As soon as you see a reaction (foaming, discolouration), work it straight away with the \u003ca href=\"\/en\/collections\/zubehoer-felgenpflege\"\u003ewheel brush\u003c\/a\u003e and rinse off thoroughly with a pressure washer. Several short passes beat one long one — the acid is saturated after 2 minutes max and does nothing but damage after that. PPE is a must: acid-resistant gloves, safety goggles, long-sleeved work gear. Rinse any splashes off your skin immediately with plenty of water.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-felgenreiniger-extrem-fe-felgenreiniger-sauer_anwendung.png?v=1776206205\" alt=\"Koch-Chemie Fe in use: low-pressure spraying onto a pre-wetted wheel\" loading=\"lazy\" width=\"900\" height=\"1200\"\u003e\n\n\u003ch3\u003eSteel wheel yes. Polished alloy no.\u003c\/h3\u003e\n\u003cp\u003eThe Fe is built for acid-resistant materials. Steel wheels, painted alloy wheels with intact clear coat, wash-bay tiles and commercial vehicles all qualify. Its cleaning power on baked-on brake dust from trucks, buses and construction machines is unmatched across the trade — no acid-free alternative comes close to that depth.\u003c\/p\u003e\n\n\u003cp\u003eThe chemistry is clear: hydrochloric acid dissolves iron oxide (Fe₂O₃) out of the brake dust and converts it into water-soluble iron chloride, which flows away with the rinse water. The same principle works on limescale (calcium carbonate), cement haze after building work and scale in wash bays. Inorganic grime dissolves in seconds; organic grime like tar, oil or insect residue isn't touched — that needs a solvent or surfactant cleaner.\u003c\/p\u003e\n\n\u003cp\u003eThe speed advantage is genuinely measurable. Acid-free wheel cleaners working via thioglycolate need 3 to 5 minutes of dwell time per pass and often two or three passes on baked-on brake dust. The Fe dissolves the same grime in 30 to 90 seconds in a single pass. In a detailing business with ten vehicles a day, that's a time saving of 60 to 90 minutes — costed as an hourly rate, the investment in the big pack pays for itself within a few weeks.\u003c\/p\u003e\n\n\u003cp\u003eWhere the Fe destroys on contact: polished aluminium with no paint protection, magnesium, chrome (attacked too, even lightly), zinc, marble, natural stone and all anodised surfaces. A pH of -0.2 is practically concentrated hydrochloric acid — this is industrial chemistry, not detailing care. Before the first use on any unknown surface, test a hidden spot, at least 5 cm² for 30 seconds, then rinse off thoroughly and check it visually.\u003c\/p\u003e\n\n\u003cp\u003eIf the wheels are polished, chromed or uncoated, grab the acid-free \u003ca href=\"\/en\/products\/koch-chemie-felgenblitz-saurefrei-fb-felgenreiniger\"\u003eKoch-Chemie Felgenblitz \"Fb\"\u003c\/a\u003e — it works through iron-binding agents instead of acid and is safe on all common wheel types. If the wheels are painted, carry little brake dust and you clean them regularly, an acid-free cleaner is enough too. The Fe only justifies itself when the brake dust is baked on and acid-free cleaners hit their limit.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-felgenreiniger-extrem-fe-felgenreiniger-sauer_ergebnis.png?v=1776206212\" alt=\"Koch-Chemie Fe result: clean wheel with water beading\" loading=\"lazy\" width=\"900\" height=\"1200\"\u003e\n\n\u003ch3\u003eShop, detailer, wash bay and depot\u003c\/h3\u003e\n\u003cp\u003eThe Fe is not a consumer product. It belongs in the shop, in the detailing bay and in the wash tunnel. Use it privately in your home garage and you're buying 11 kg of concentrate for a job an acid-free cleaner solves just as well in a 1-litre format — at far less risk to the wheel and to your own health.\u003c\/p\u003e\n\n\u003cp\u003eThe typical use cases are easy to name. Detailers with several vehicles a day need the fast, deep action on first-time clean-ups of neglected cars. Workshops with a tyre-change service use it during wheel swaps — above all in spring after the winter season, when road salt and baked-on brake dust sit together on the steel wheel.\u003c\/p\u003e\n\n\u003cp\u003eTruck and bus wash bays run it as their main cleaner against brake dust and road grime. Construction firms clean their vehicles of cement and limescale residue after a job. Building cleaners work with it on shop tiles, in maintenance halls and on industrial floor surfaces when limescale deposits, rust marks or cement haze need to come off.\u003c\/p\u003e\n\n\u003cp\u003eFor the buying decision it comes down to the pack. The 11 kg canisters are the right format for workshops with occasional need and detailers doing one or two vehicles a day — at 1:5 dilution they last for around 250 wheel sets. The 22 kg canister pays off for detailing businesses and smaller wash bays.\u003c\/p\u003e\n\n\u003cp\u003eThe 225 kg drum with pump system is the standard size for truck wash bays, large operations and building cleaners with daily use. The price per kg drops by about 12 percent from the 11 kg pack to the 225 kg drum — the bigger investment pays off from steady daily demand. If you're unsure which pack fits, start with the 11 kg canister and step up once you're going through three canisters a quarter.\u003c\/p\u003e\n\n\u003cp\u003eAs a complete setup you pair the Fe for the first clean with the acid-free Felgenblitz \"Fb\" for regular follow-up cleaning — that way you limit acid use to what genuinely can't be shifted acid-free. For tyre care afterwards, reach for a regular \u003ca href=\"\/en\/collections\/reifenpflege\"\u003etyre dressing\u003c\/a\u003e. Store in the original canister, frost-free, away from food, kept separate from alkaline cleaners (reaction risk).\u003c\/p\u003e\n\n\u003cp\u003eWithin the Koch-Chemie wheel cleaner family, the Fe sits at the top of the acidic line. If you need even more cleaning power and want to work with a three-acid blend, go for the \u003ca href=\"\/en\/products\/koch-chemie-triple-acid-star-ta-felgenreiniger\"\u003eTriple Acid Star \"Ta\"\u003c\/a\u003e.

We often get messages like \"the glass cleaner leaves streaks\". Usually the wiping happened on a warm pane in the sun, where the film flashes off before the cloth lifts it. Work on a cold pane in the shade and go by the two-cloth rule: lift the dirt with 1 damp cloth, then buff dry in straight passes with a dry glass cloth. More product doesn't clean better, it tends to leave edges.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eSpray it on neat, pull it off streak-free with two cloths\u003c\/h3\u003e\n\u003cp\u003eYou spray the Glass Cleaner \"Gc\" on neat from 20 to 30 cm onto the cold, shaded pane and pull it off with a dry microfibre glass cloth in straight passes. That way no film of water is left standing to flash off.\u003c\/p\u003e\n\u003cp\u003eOutside, the cleaner lifts bug splatter, pollen and the greasy road film. With a baked-on bug front, let the cleaner soak for about 30 seconds and only then pull it off, rather than scrubbing harder. That goes easy on the glass and on the wiper blades.\u003c\/p\u003e\n\u003cp\u003eInside, it's about the greasy film off-gassing from the dash and about nicotine. If you want to \u003cem\u003eclean your car windows from the inside\u003c\/em\u003e, spray sparingly onto the cloth rather than straight onto the glass, so no mist drifts onto a display or a vent. With a \u003ca href=\"\/en\/products\/the-rag-company-diamond-280-gsm-mikrofaser-glastuch\"\u003emicrofibre glass cloth\u003c\/a\u003e especially, the cloth quality decides whether the loosened dirt gets picked up or just smeared around.\u003c\/p\u003e\n\u003cp\u003eThe second, bone-dry pass over the finished pane lifts the last haze out. That's exactly the step most people skip, and that's exactly where you get the streaks you spot later in backlight. A good glide additive makes the difference here between any old cleaner and a real car glass cleaner.\u003c\/p\u003e\n\u003cp\u003eWhy the cold pane? The additive only works its glide as long as the film is liquid. On hot glass the water flashes off too fast, the cleaner grabs and the cloth just pushes the dirt around. In the shade or early in the morning you've got that window of time. Wash new microfibre cloths once without softener before they ever touch glass too, otherwise they carry sizing onto it that pulls streaks all by itself.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-glass-cleaner-gc-glasreiniger_anwendung.png?v=1780006597\" alt=\"Koch-Chemie Glass Cleaner Gc being sprayed on a car window and pulled off with a microfibre cloth\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eWhat the Gc is built for and what it isn't\u003c\/h3\u003e\n\u003cp\u003eThe Gc cleans glass, it doesn't seal it and it doesn't belong in the washer reservoir.

One verified customer puts it well: with stubborn dirt you need 2 to 3 passes rather than scrubbing under pressure. A short soak and another pull is gentler and quicker in the end, because you avoid scratches you'd have to polish out later.\u003c\/p\u003e\n\u003cp\u003eAnti-fog protection is something the Gc deliberately leaves out. It gets you clean, clear glass, but against fogging from the inside only an anti-fog treatment helps for the long run. Clean glass does fog up far more evenly though, and so far less of a bother than a greasy film.\u003c\/p\u003e\n\u003cp\u003eBeyond the car the Gc cleans mirrors, interior and exterior, motorcycle visors, instrument glass and smooth surfaces around the house like tiles or stainless steel. The only place to be careful is on matte anti-glare nav and instrument displays: there you always spray onto the cloth and work with little pressure, so the coating doesn't suffer. On clear glass and glossy plastic headlights it works with no restrictions.\u003c\/p\u003e\n\u003cp\u003eIn a smoker's car a tacky nicotine film settles on the inside glass, scattering the light and making everything look yellowed.

The commuter grabs the 1-litre bottle, the detailer the 10 or 20-litre container.\u003c\/p\u003e\n\u003cp\u003eGlass cleaners are in highest demand in spring: pollen and bug season drives demand about 40 percent over the quiet winter level. If you've got a bottle in the boot now, you clean the windscreen on the road instead of driving into the low sun with a pollen film and streaks.\u003c\/p\u003e\n\u003cp\u003eDay-to-day the difference shows in the details: no streaks in backlight, no haze on the inside glass that turns oncoming headlights into stars at night. If you drive a lot with the sun low or in the dark, you notice a streak-free pane straight away.\u003c\/p\u003e\n\u003cp\u003eThe Gc is fuss-free on cost: 1 litre ready-to-use lasts many weeks of commuter life depending on how much you spray, and decanting the 10-litre container into a spray bottle costs you far less per litre. Store the cleaner frost-free and the spray function stays reliable across the whole shelf life. An opened bottle in the car survives the summer heat better if it isn't left baking in full sun all the time.\u003c\/p\u003e\n\u003cp\u003eHow often you clean depends on your driving: if you commute daily, keep the windscreen clear inside about every 2 weeks and outside as needed with pollen or bugs. High-mileage drivers and detailers with several cars a day get the most out of the big container and a spray bottle fixed to the trolley. That turns reaching for the car glass cleaner into routine rather than the exception.\u003c\/p\u003e\n\u003cp\u003eThe one trick hardly anyone does and that stops most streaks: clean the inside first, then the outside, and pull horizontally inside, vertically outside. If a streak is left after cleaning, the direction tells you straight away whether it's on the inside or the outside, and you only fix it there. That saves you the third pass and the guessing.
