Koch Chemie Vorreiniger b High Foaming Pre Cleaner 10L

Koch Chemie Vorreiniger b High Foaming Pre Cleaner is the strongest alkaline cleaner in the range for extreme soiling such as insects, bird droppings, environmental and wheel rims. Anyone who wants to remove the heaviest dirt in a way that is gentle on the paintwork but effectively needs a strong product.

This dirt is loosened extremely quickly with the help of the strongly alkaline and foam-rich active formula. Therefore, the pre-cleaner b is an ideal candidate for heavily used washing systems in order to achieve perfect cleaning results as quickly as possible.

Special corrosion inhibitors ensure high material compatibility with regard to sensitive surfaces such as anodised aluminium.

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, it's not always achievable, so we've also listed what options are suitable for occasional use after longer periods between washes.
