A concentrated, high-foaming vehicle presoak designed for use in both touch-free and friction car and truck wash facilities. It provides abundant foam for complete vehicle coverage and superior clinging time on surfaces. Its low pH formula makes vehicle paint glow brighter. Low pH Vehicle Wash will also reduce alkalinity to enhance the performance of drying agents and clear coat protectants. Its synthetic detergents rinse completely and freely to aid in the elimination of streaking. Contains no HF or ammonium bifluoride, so it is safer than other formulations.
