A silicone oil-free rubber and plastic care product for vehicle interiors that darkens floor mats, pedal rubbers, and cargo area linings to a satin finish without leaving a slippery surface. Not intended for glossy dashboards or permanently weathered exterior plastic parts.\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 product from Koch-Chemie that cleans, nourishes, and darkens rubber and plastic surfaces in the vehicle interior to a matte finish. Because the formulation contains no silicone oils, the treated surface remains grippy—a crucial point for pedal rubbers and floor mats, where slipperiness is not a cosmetic problem but a safety risk. After treatment, the mats appear fresh and dark, without the typical plastic sheen of 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 dirty rubber mat\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSilicone-free and therefore non-slip.\u003c\/strong\u003e Commercial silicone oil-based cockpit sprays leave a smooth film on rubber floor mats. When braking, the foot slides on the mat, and the shoe loses grip on the pedal rubber. Gummifix works without silicone oils and maintains the natural grip structure of the surface—the difference is noticeable in the first emergency stop, not just measurable in the lab.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSatin-matte darkening instead of plastic sheen.\u003c\/strong\u003e The formulation refreshes color depth and structure without lacquering the surface. Rubber mats look like they did the day they were bought, plastic footwells appear fresh instead of reflective. This is the look workshops and detailers use for used cars before sales photos are taken—enhancing without overdoing it.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOne liter is enough for 20 to 30 sets of mats.\u003c\/strong\u003e For a complete set of four mats, you need 30 to 50 ml of product. The 1-liter canister thus covers one to two years of regular care, while the 10-liter canister is the industry standard for workshops and fleet operations. Approximately €0.35 in material costs per mat set from the 1-liter container—and even significantly less from the 10-liter canister.\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 The most common mistake with Gummifix is applying it too thickly. The product does not penetrate the surface like a coating; it dries on it—too much material means a greasy film instead of satin-matte depth. Spray a thin mist, spread evenly with a microfiber cloth, and let it dry completely for at least 30 minutes before returning the mats to the car. If you put the mats back wet, you'll get exactly the slippery surface that the silicone-free formula is supposed to prevent.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eClean mat. Thin layer. 30 minutes drying.\u003c\/h3\u003e\n\u003cp\u003eGummifix is sprayed or applied with a sponge onto a clean, dry surface—not on damp or freshly shampooed rubber. Residual moisture dilutes the product and prevents uniform absorption by the surface.\u003c\/p\u003e\n\n\u003cp\u003eBefore treatment, remove the mats from the car, shake them out, degrease them with APC or a \u003ca href=\"\/en\/collections\/kunststoffpflege\"\u003eplastic cleaner\u003c\/a\u003e, and rinse them thoroughly. Only when the surface is visibly clean and dry does treatment make sense. Eight to ten sprays per mat, spread briefly with a microfiber cloth—for heavy soiling, it's better to treat it thinly twice than thickly once.\u003c\/p\u003e\n\n\u003cp\u003eThe same logic applies to pedal rubbers on a smaller scale: three to four sprays per pedal, spread with a fingertip on a microfiber cloth, and let it air dry. Most pedal rubbers have a fine profile that quickly clogs with dust and rubber abrasion—here, Gummifix not only enhances the color but also cleans as it's spread.\u003c\/p\u003e\n\n\u003cp\u003eDrying time is the adjustable parameter most often skipped. At 20 °C room temperature, complete airing takes 30 to 60 minutes; it's faster in the summer sun and significantly longer in a cold garage in winter. As a rule of thumb: if the mat no longer feels damp to the touch and doesn't leave a film on your glove, it can go back into the car. When in doubt, air it for an hour longer, not five minutes shorter.\u003c\/p\u003e\n\n\u003cp\u003eWorking directly from the 1-liter canister is possible but too imprecise for fine pedal rubbers or seat consoles. A spray bottle with a fine-mist adjustable head makes the difference between precise dosing and soaking—especially since pedal rubbers are small areas that can easily receive too much product.\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 spray head Star is 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 application area for Gummifix is horizontal surfaces in the footwell and cargo area: rubber floor mats, plastic footwells, pedal rubbers, cargo area linings, and door sill trims. On these surfaces, the satin-matte darkening shows its strengths—a fresh look without the artificial shine that looks unnatural in the footwell.\u003c\/p\u003e\n\n\u003cp\u003eThe product also works reliably on rubber seals, door rubbers, and trunk seals—it keeps the seals supple and prevents hairline cracks due to drying out, especially after UV exposure in summer. Applying it to the seals once per season is sufficient, twice a year is enough for vehicles that are often parked outdoors.\u003c\/p\u003e\n\n\u003cp\u003eHowever, Gummifix is not the first choice for tire sidewalls and permanently weathered exterior rubber parts—the durability under weather conditions is about two to three washes, then the product starts to wash off. For tires, there are dedicated tire care products with longer durability and UV protection, and for exterior plastics such as bumper attachments or wheel arch covers, we have \u003ca href=\"\/en\/products\/koch-chemie-plast-star-pss-premium-kunststoffpflege-siliconoelfrei\"\u003eKoch-Chemie Plast Star\u003c\/a\u003e in our range—also silicone oil-free, but with higher weather resistance.\u003c\/p\u003e\n\n\u003cp\u003eWhere Gummifix is not the right product: glossy dashboards, cockpit plastics on the dashboard, and door panels. There, you usually want a slight sheen, not matte darkening. For this, \u003ca href=\"\/en\/products\/koch-chemie-top-star-ts-innenraum-kunststoffpflege\"\u003eKoch-Chemie Top Star\u003c\/a\u003e is the alternative—the same brand with a silky-glossy finish instead of matte darkening.\u003c\/p\u003e\n\n\u003cp\u003eIf safety on pedals and mats is your priority, use Gummifix. If you want shine on the dashboard, opt for Top Star. Having both in the garage costs less than a workshop visit and covers 90 percent of interior care—for the remaining 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 vehicle 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 its range—the same product category, three different tasks. This classification saves you from the wrong purchases we often see in support when customers confuse the three abbreviations.\u003c\/p\u003e\n\n\u003cp\u003eGummifix—abbreviation Guf—is the matte, non-slip variant for floor mats and pedal rubbers. Koch-Chemie Rubber and Plastic Care Gkg produces a distinct high gloss and is intended for visible exterior parts such as bumper plastics or wheel arch covers—where gloss is desired. The Gkv is the third level with an additional vinyl component for boat covers, convertible tops, and vinyl flooring—more specialized, usually too much product and too expensive per application for everyday vehicles.\u003c\/p\u003e\n\n\u003cp\u003eOur application profile from 10 years of practice: Gummifix for everything that is touched by shoes when getting in and out. Gkg for visually visible exterior plastics that should shine. Gkv for special materials like marine applications. If you only want one product on the shelf and primarily care for the footwell, Gummifix is the right choice.\u003c\/p\u003e\n\n\u003cp\u003eThe 1-liter canister lasts for one to two seasons for one vehicle, the 10-liter canister is the industry standard for workshops, car dealerships, and fleets with 20 to 50 vehicles. Between the two container sizes are the two- and three-packs of the 1-liter container, which prepare for the step up to the 10-liter canister without having to immediately jump to commercial quantities.\u003c\/p\u003e\n\n\u003cp\u003eA Detailing1 insight you won't read from the manufacturer: Gummifix is also the ideal product after steam cleaning the interior. After steam cleaning, rubber floor mats are extremely open-pored and absorb care particularly well—a single thin application then provides a depth and durability that would require three applications without prior preparation. If you steam clean your mats once a year and then treat them immediately, you'll have mats that still look like they did after six months, even after three years.\u003c\/p\u003e\n\n\u003cp\u003eThe second insight concerns the combination with interior textile coating: if you have carpet floor mats in your car and rubber floor mats as a winter option, treat the rubber mats thoroughly with Gummifix once in the spring before they disappear into the basement. The product prevents drying out and brittleness over the summer—in autumn, the mats return to the car and look like they did the day you stored them. No chalking, no white streaks, 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 compared\" loading=\"lazy\"\u003e\u003c\/p\u003e\n","brand":"Koch-Chemie","offers":[{"title":"1000ml","offer_id":48463594979663,"sku":"D1-KCX-48001","price":9.67,"currency_code":"EUR","in_stock":true},{"title":"2x 1000ml","offer_id":49723985854799,"sku":"D1-KCX-48001_2","price":18.95,"currency_code":"EUR","in_stock":true},{"title":"3x 1000ml","offer_id":49723985887567,"sku":"D1-KCX-48001_3","price":28.13,"currency_code":"EUR","in_stock":true},{"title":"10 liters","offer_id":48463595012431,"sku":"D1-KCX-48010","price":85.91,"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.co\/en\/products\/koch-chemie-gummifix-guf-gummipflege-kunststoffpflege","provider":"Detailing1","version":"1.0","type":"link"}
