Koch Chemie Precleaner B (Vb) - Pre-Wash 5L

Preliminary Cleaning Agent

Highly concentrated alkaline cleaner for preliminary cleaning, phosphate-free and creating an intense foam, suitable for washing personal and commercial vehicles.

Special anti-corrosion inhibitors ensure high material compatibility with sensitive components, such as anodized aluminum. It is also optimal for biological treatment of service water. Rapid separation and testing in accordance with the ÖNORM 5106 standard (tested concentration of 0.05% by weight). Class A compliance with VDA standards.
