A silicone-oil-free rubber and plastic care for your car interior that darkens floor mats, pedal rubbers and boot liners to a soft satin finish without leaving a slippery surface behind. Not meant for glossy dashboards or outdoor plastic trim that takes the weather all year.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp id=\"speakable-definition\"\u003e\u003cstrong\u003eKoch-Chemie Gummifix\u003c\/strong\u003e is a silicone-oil-free care from Koch-Chemie that cleans, feeds and matte-darkens rubber and plastic surfaces inside the car. Because there are no silicone oils in the formula, the treated surface stays grippy — a make-or-break point on pedal rubbers and floor mats, where slipperiness isn't a cosmetic problem but a safety risk. After treatment the mats look fresh and dark, without the typical plastic shine you get from cheap cockpit sprays.\u003c\/p\u003e\n\n\u003cp class=\"d1-scene-image\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-gummifix_hero.png?v=1776195706\" alt=\"Koch-Chemie Gummifix Guf in the warehouse entrance with a dirty rubber mat\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSilicone-free, and grippy because of it.\u003c\/strong\u003e Run-of-the-mill cockpit sprays built on silicone oil leave a slick film on rubber floor mats. Brake hard and your foot slides on the mat, your shoe loses grip on the pedal rubber. Gummifix works without silicone oils and keeps the natural grip of the surface — you feel the difference in the first emergency stop, not just on a lab readout.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSatin darkening instead of plastic shine.\u003c\/strong\u003e The formula brings back colour depth and texture without lacquering the surface. Rubber mats look like the day you bought them, plastic footwells look fresh rather than mirror-like. This is the look detailers and reconditioners reach for on used cars before the sales photos go up — sharpen it up without overdoing it.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOne litre covers 20 to 30 sets of mats.\u003c\/strong\u003e You need 30 to 50 ml of product per full four-mat set. So the 1 L canister covers one to two years of regular care, while the 10 L canister is the trade standard for workshops and fleets. That works out to about EUR 0.35 in material per set of mats from the 1 L container — and a fair bit less from the 10 L canister.\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 The most common mistake with Gummifix is laying it on too thick. The product doesn't soak into the surface like a coating, it dries on top — too much material means a greasy film instead of satin depth. Spray on a thin mist, spread it evenly with a microfibre cloth, and let it flash off completely for at least 30 minutes before the mats go back in the car. Put the mats in wet and you get exactly the slippery surface that going silicone-free was meant to avoid.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eClean mat. Thin coat. 30 minutes to dry.\u003c\/h3\u003e\n\u003cp\u003eYou spray Gummifix onto the clean, dry surface or wipe it on with a sponge — not onto wet or freshly shampooed rubber. Leftover moisture dilutes the product and stops the surface from taking it up evenly.\u003c\/p\u003e\n\n\u003cp\u003eBefore you treat them, the mats come out of the car, get shaken out, degreased with APC or a \u003ca href=\"\/en\/collections\/kunststoffpflege\"\u003eplastic cleaner\u003c\/a\u003e and rinsed clear. Only once the surface is visibly clean and dry does the care make any sense. Eight to ten spray bursts per mat, spread it quickly with a microfibre cloth — with heavy soiling, go twice thin rather than once thick.\u003c\/p\u003e\n\n\u003cp\u003eSame logic for pedal rubbers, just on a smaller scale: three to four bursts per pedal, spread it with a fingertip on the microfibre cloth, let it flash off. Most pedal rubbers have a fine tread that quickly clogs with dust and rubber dust — here Gummifix doesn't just lift the colour, it cleans as you spread it.\u003c\/p\u003e\n\n\u003cp\u003eDrying time is the setting that gets skipped most often. At 20 °C room temperature, full flash-off takes 30 to 60 minutes, quicker in the summer sun, a lot longer in a cold winter garage. Rule of thumb: when the mat doesn't feel damp to the touch and you don't leave a film on your glove, it can go back in the car. When in doubt, air it an hour longer, not five minutes shorter.\u003c\/p\u003e\n\n\u003cp\u003eWorking straight from the 1 L canister does work, but it's too imprecise on fine pedal rubbers or seat consoles. A spray bottle with an adjustable fine-mist head is the difference between dosing and a full bath — pedal rubbers especially are small areas that cop too much product head-on.\u003c\/p\u003e\n\n\u003cp class=\"d1-scene-image\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-gummifix_anwendung.png?v=1776198289\" alt=\"Koch-Chemie Gummifix with a Star spray head being sprayed onto a rubber floor mat\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eMats and pedals yes. Dashboard no.\u003c\/h3\u003e\n\u003cp\u003eThe core job for Gummifix is the horizontal surfaces in the footwell and boot: rubber floor mats, plastic footwells, pedal rubbers, boot liners and sill trims. On these surfaces the satin darkening plays to its strengths — a fresh look without the artificial shine that looks out of place down in the footwell.\u003c\/p\u003e\n\n\u003cp\u003eIt works reliably on rubber seals, door rubbers and boot seals too — it keeps the seals supple and stops them cracking from drying out, especially after UV exposure in the summer. Once a season on the seal rubbers is enough for that; twice a year is plenty for cars that spend a lot of time outdoors.\u003c\/p\u003e\n\n\u003cp\u003eOn tyre sidewalls and outdoor rubber that's permanently weathered, Gummifix isn't your first pick — its life under the weather is around two to three washes, then the care starts to wash off. For tyres there are dedicated tyre dressings with longer staying power and UV protection; for outdoor plastics like bumper add-ons or wheel-arch trims we stock the \u003ca href=\"\/en\/products\/koch-chemie-plast-star-pss-premium-kunststoffpflege-siliconoelfrei\"\u003eKoch-Chemie Plast Star\u003c\/a\u003e — also silicone-oil-free, but with higher weather resistance.\u003c\/p\u003e\n\n\u003cp\u003eWhere Gummifix is the wrong product: glossy dashboards, cockpit plastic on the dash and door cards. There you usually want a light shine, not matte darkening. The \u003ca href=\"\/en\/products\/koch-chemie-top-star-ts-innenraum-kunststoffpflege\"\u003eKoch-Chemie Top Star\u003c\/a\u003e is the alternative for that — same brand, with a satin-gloss finish instead of matte darkening.\u003c\/p\u003e\n\n\u003cp\u003eIf safety on the pedals and mats is your priority, grab the Gummifix. If you want shine on the dashboard, reach for the Top Star. Having both in the garage costs less together than a single shop visit and covers 90 percent of interior care — for the other 10 percent (leather, Alcantara, upholstery) you'll need dedicated products anyway.\u003c\/p\u003e\n\n\u003cp class=\"d1-scene-image\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-gummifix_ergebnis.png?v=1776193282\" alt=\"Floor mat after Koch-Chemie Gummifix treatment in the car footwell\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eGummifix or Gkg or Gkv\u003c\/h3\u003e\n\u003cp\u003eKoch-Chemie has three rubber and plastic care products in the range — same product category, three different jobs. This breakdown saves you the wrong buys we often see in support when customers mix up the three abbreviations.\u003c\/p\u003e\n\n\u003cp\u003eGummifix — abbreviation Guf — is the matte, grippy option for floor mats and pedal rubbers. The Koch-Chemie Gummi- und Kunststoffpflege Gkg produces a clear high gloss and is meant for visible exterior parts like bumper plastic or wheel-arch trims — where you actually want shine. The Gkv is the third tier with an added vinyl component for boat covers, convertible tops and vinyl flooring — more specialised, usually too much product and too pricey per use for everyday cars.\u003c\/p\u003e\n\n\u003cp\u003eOur usage profile from 10 years on the job: Gummifix for everything your shoe touches getting in and out. Gkg for visible exterior plastics that should shine. Gkv for special materials like marine applications. If you only want one product on the shelf and mostly look after the footwell, Gummifix is the right call.\u003c\/p\u003e\n\n\u003cp\u003eThe 1 L canister lasts one to two seasons on one car, the 10 L canister is the trade standard for workshops, dealerships and fleets with 20 to 50 vehicles. Between the two sizes sit the two- and three-packs of the 1 L container, which ease the step up to the 10 L canister price-wise without having to jump straight to a commercial quantity.\u003c\/p\u003e\n\n\u003cp\u003eA Detailing1 insight you won't read from the manufacturer: Gummifix is also the ideal product after an interior clean with steam. After steam cleaning, rubber floor mats are extremely open-pored and take care up especially well — a single thin coat then gives you a depth and staying power that would take three applications without the prep. Steam-clean your mats once a year and care for them straight after, and you'll have mats that still look after three years like they did at six months.\u003c\/p\u003e\n\n\u003cp\u003eThe second insight is about pairing it with how you handle interior textiles: if you've got carpet floor mats in the car and rubber floor mats as a winter set, give the rubber mats one solid treatment with Gummifix in spring before they go down to the cellar. The product stops them drying out and going brittle over the summer — in autumn the mats come back into the car looking like the day you put them away. No chalking, no white haze, no hardened edges.\u003c\/p\u003e\n\n\u003cp class=\"d1-scene-image\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-gummifix_lineup.png?v=1776195721\" alt=\"Koch-Chemie Gummifix 1L bottle and 10L canister side by side\" loading=\"lazy\"\u003e\u003c\/p\u003e","brand":"Koch-Chemie","offers":[{"title":"1000 ml \/ 1 liter","offer_id":48463594979663,"sku":"D1-KCX-48001","price":8.23,"currency_code":"EUR","in_stock":true},{"title":"2x 1000ml","offer_id":49723985854799,"sku":"D1-KCX-48001_2","price":16.44,"currency_code":"EUR","in_stock":true},{"title":"3x 1000ml","offer_id":49723985887567,"sku":"D1-KCX-48001_3","price":24.66,"currency_code":"EUR","in_stock":true},{"title":"10 liters","offer_id":48463595012431,"sku":"D1-KCX-48010","price":68.57,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-gummifix-gummipflege-kunststoffpflege.jpg?v=1710622833","url":"https:\/\/detailing1.lu\/en\/products\/koch-chemie-gummifix-guf-gummipflege-kunststoffpflege","provider":"Detailing1","version":"1.0","type":"link"}
