Koch Chemie Vorreiniger B (Vb) - Pre-wash 11KG

Pre-cleaner

Highly concentrated alkaline pre-cleaning agent, phosphate-free and generating intense foam, for washing personal and commercial vehicles. A combination of high-quality complexing agents and special surfactants quickly dissolves tough dirt such as insects, bird droppings, environmental grime, and wheel contaminants, making this product particularly suitable for use in busy car wash facilities and contactless high-pressure washers. Special anti-corrosion inhibitors ensure high material compatibility with sensitive components, such as anodized aluminum. It is also optimally suitable for biological treatment of utility water.
