Commercial grade, large vehicle washers are utilized by many sectors of the transportation industry as a component of regular fleet maintenance. Vehicle washes can help extend the functional life of vehicles. Whether operators are removing road salt from winter trips, or knocking away grit from freshly paved roads, routine fleet cleaning can prevent build up and slow down the process of oxidation, or rusting. Large vehicle washers come in a variety of forms including touch-free, traditional roller, and undercarriage systems. Touch-free systems are easier on paint finishes as high-pressure nozzles are used over direct contact brushes.
