Abstract: A rollover type car wash and rinse machine which uses permeate from a reverse osmosis unit for a final rinse operation. The machine is operator controlled to wash and initially rinse cars with a spray arch using raw water and concentrate from the reverse osmosis unit. A final rinse can then be performed with a second spray arch using permeate alone, and only after a wash and initial rinse has been performed.

Abstract: A machine and method for preparing the surface and waxing vehicles. The machine has an improved head construction comprising a plurality of pads of a heavy wool and Orlon fabric fastened at their inner ends to a rotating shaft and slit inwardly on 21/2 inch centers from their outer edges for a distance of 12 inches. The strips formed each overlap two strips on each adjacent sheet. Wax is applied to the surface at 185-190 rpm while traversing the vehicle at 5.5 - 6.0 feet per minute. A first traversal end to end and return with the wax still moist cleans the surface grime and oxidized paint off. A second traversal end to end and return then buffs dried wax to a high gloss finish.
