Koch Chemie Vorreiniger B Foaming Pre-Cleaner:

Koch-Chemie Vorreiniger B is a highly concentrated, phosphate-free, alkaline, high foaming pre-cleaner for car and truck pre-washing. The combination of high-quality complexing agents and special surfactants dissolves even stubborn incrustations such as insects, bird droppings, environmental and rim dirt extremely quickly. Therefore, Vorreiniger B is ideally suited in particular for heavily frequented car washes and for non-contact high-pressure washing. Special corrosion inhibitors ensure high material compatibility with regard to sensitive components such as anodised aluminium. Also suited for copolymer de-waxing. Optimally suited as well for biological service water treatment plants.
