Koch Chemie Vorreiniger b VB NTA Free is a highly concentrated, phosphate and NTA free, alkaline, high foaming pre-cleaner for car and truck pre-washing. In other words, Vorreiniger b VB is a Professional grade alkaline (high pH) Snow Foam Vehicle Prewash. 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 and is therefore ideally suited for heavily frequented car washes and for touch free high-pressure washing. At high dilutions, Vorreiniger b VB can be used as a strip wash.
Special corrosion inhibitors ensure high material compatibility with regard to sensitive components such as anodised aluminium. Vorreiniger b VB is also suited for copolymer dewaxing.
Koch Chemie Vorreiniger b VB is optimally suited as well for biological service water treatment plants. Quick-separating and tested in accordance with ÖNORM 5106 (test concentration 0.05% mass). VDA conform to class A: reaction time max. 5 min, max. application concentration 1:300. Class B: reaction time max. 1 min, max. application concentration 1:30.
Areas of use:-
Cars, commercial vehicles, construction machines, steel rims and alkali-resistant painted aluminium rims.

A General Application Guide.
The below graph is an indicator of what products are best suited as a maintenance pre-wash, depending on the protective products that are on the surface. It’s up to the user to decide on the amount of chemical energy required to safely remove as much contamination as possible. Even though the best course of action is to wash frequently, limiting the amount of chemical energy required is not always achievable, so we’ve also listed what options are suitable for occasional use after longer periods between washes.
Important to note that we recommend taking a holistic approach to your vehicles exterior and also preserving sensitive materials that are commonly overlooked such as plastic and rubber trim with the use of Plast Star PSS
