Suitable for use in car wash facilities for passenger cars and commercial vehicles, the VehiclePro Brush Shampoo RM 811 Classic reliably removes grease, oil, emissions, and typical road dirt. It efficiently supports the glide of the brushes, simultaneously reduces their re-soiling, and thus maintains functionality. Additionally, RM 811 Classic can also be used as an active foam and is gentle on paint surfaces. This concentrated brush shampoo allows for the cleaning of up to 100 passenger cars per liter, is compatible with subsequent wax products, and prevents potential streaking on the paint. The surfactants contained in the formulation are biodegradable according to OECD standards. Furthermore, it separates oil and water quickly in oil separators.
