Koch Chemie Gummifix is a professional rubber and plastic care product engineered specifically for interior surfaces where slip resistance matters. Unlike standard dressings that leave a greasy coating, Gummifix is silicone-free and non-greasy, restoring rubber and plastic surfaces to a clean, natural as-new appearance without creating a slippery surface that would be unsafe on floor mats, pedal covers, and other high-contact interior areas.

Ideal for rubber floor mats, plastic floor surfaces, door seals, trunk liners, and any interior rubber or plastic area in cars, vans, buses, and commercial vehicles where you want the surface to look restored and cared for without compromising grip or safety. Professional-grade formula trusted by fleet detailers and commercial vehicle operators who maintain large numbers of vehicles regularly.

If you are looking for a non-slip rubber restorer for car interiors, a silicone-free rubber and plastic dressing for floor mats and pedal areas, or a professional Koch Chemie rubber care product that restores appearance without creating a slippery surface, Gummifix is the purpose-built solution for this specific application. Available in 1L and 5L.

Koch Chemie Gummifix Usage

Gummifix is Koch Chemie's rubber conditioner and restorer — brings weatherstripping, door seals, and window rubber back to supple life. Prevents winter freezing.

• Application: Wipe onto clean rubber seals with a microfiber or applicator. Wipe off excess.
• Winter prep: Apply before temps drop below 32°F — keeps door seals from freezing shut.
• Coverage: 1L lasts through many vehicles — a little goes a long way.

Frequently Asked Questions

Does Koch Chemie Gummifix really keep car doors from freezing shut in winter?

Yes — it's one of the most common use cases in Midwestern US and German markets. The product conditions rubber to stay supple below freezing and prevents moisture from bonding seal to frame. Apply in fall before first freeze for best results.

How often should I apply Koch Chemie Gummifix?

2-3 times per year is usually enough. Once in spring (after winter damage), once in fall (winter prep), and optionally mid-summer if you're in heavy UV. It doesn't wash off in car washes.

Is Koch Chemie Gummifix safe on convertible tops?

It's formulated for rubber — not fabric convertible tops. For convertible top rubber seals (around the window frames), yes. For the fabric top itself, use a dedicated top cleaner and protectant.
