Brush-less Presoak is designed for use as a single step cleaning compound in touchless car wash systems. The high use dilution rate affords a superior economy tot he wash operator. It generates copious amounts of foam (when used with compressed air injection) at use dilution. Brush-less Presoak will remove road film from even the most tenacious of vehicles to clean. It will not damage vehicles when used as directed. Rinses free and spotless in cold or hot water. The cationic polymer chemistry goes to work to break the magnetic bond that holds dirt on the vehicle. Once the magnetic bond is broken, the dirt and road film simply washes away.
