Acid Car Wash Shampoo A. Concentrated acid shampoo for gantry car washes and tunnel car washes with conventional process-water treatment. The combination of mild acids and foaming surfactants guarantees gentle but thorough cleaning of vehicles, bonds to water-hardening elements, prevents limescale, and neutralises both the vehicle surface and the alkaline process water from the precleaning stage. Boosts self-cleaning and therefore the service life of brushes. Selected surfactants provide optimum preparation for drying. Encourages rapid sedimentation of dirt. Limited suitability for biological process-water treatment systems due to phosphate content. Quick-separating in accordance with ÖNORM 5105.
