Koch Chemie Vorreiniger B is a highly concentrated, phosphate-free alkaline precleaner developed for powerful vehicle pre-washing. Its advanced blend of high-quality complexing agents and specialized surfactants quickly dissolves stubborn contaminants, including insects, bird droppings, road film, environmental dirt, and brake dust.
Designed for professional car washes, commercial vehicle cleaning, and non-contact high-pressure washing, Vorreiniger B generates rich, stable foam that maximizes cleaning performance while remaining gentle on compatible vehicle surfaces. Special corrosion inhibitors provide excellent material compatibility, including anodized aluminum and other sensitive components.
The formula is also suitable for copolymer dewaxing and is compatible with biological water treatment systems. It is quick-separating, tested according to ÖNORM 5106 standards, and complies with VDA Class A and Class B requirements for professional vehicle cleaning.
