The Ranger Stainless Steel Spray Wash Cabinets, Nos. RS-500DS and RS-750DS, are specifically designed to resist rust while washing away the grime from transmissions, engines and engine parts, industrial machinery, brake drums, wheels, and other components. The washers use high-pressure, multi-directional spray nozzles to deep clean vehicle parts while protecting the environment. While the RS-500DS is capable of degreasing a variety of vehicle components, in many shapes and sizes, the RS-750DS can take on heavy duty truck components. The larger interior size, increased load capacity, and more cleaning nozzles allow it to clean larger vehicle parts or fit more parts in at one time.
