Koch Chemie GSF Gentle Snow Foam | pH 7.5 Neutral | Coating-Safe Pre-Wash
Koch Chemie Gentle Snow Foam (GSF) is a high-performance, pH-neutral pre-wash foam designed for safe and effective vehicle cleaning. Developed for enthusiasts and professional detailers, GSF delivers a thick, clinging foam that lifts dirt and road grime without compromising wax, sealant, or ceramic protection.
Built For
- Safe pre-wash removal of dirt and contaminants
- Enthusiasts and professional detailers
- Maintenance washes on protected vehicles
- Foam cannon, foam sprayer, and bucket wash applications
Customisable Cleaning Power
For heavier contamination, GSF can be boosted with Koch Chemie Green Star to create an active pre-wash foam. This increases cleaning strength for bug splatter, road film, and stubborn grime.
Note: Enhanced mixes may reduce protection layers and are best used for deep cleaning only.
