Abstract: The process for rapidly washing vehicles accumulates one or more of the requisite cleaning liquids under pressure prior to their use and subsequently rapidly releases them to wash the vehicle. Inherent in the process is the forceful impingement of water upon a vehicle to scour dirt therefrom. The impingement water is released at a high flow rate through a multitude of nozzles arrayed and directed so that selected exterior surfaces of the vehicle are rapidly and forcefully impinged upon. Other requisite liquids may also be applied at high flow rates, thus substantially reducing the time needed to wash a vehicle and improving the economy of operation.

Abstract: The process for cleaning the exterior surfaces of vehicles utilizes pressure vessels to store the cleaning liquid, usually water, under high pressure. The cleaning liquid is then released at a high flow rate for only a few seconds, thus reducing the time needed to wash a vehicle. The cleaning liquid is released through a multitude of nozzles arrayed and moved in such a manner that all exterior surfaces of a vehicle are impinged by the liquid. The arrayed nozzles are suspended from stationary frames, one on each side of the vehicle, in such a way that the array is moved horizontally, parallel to the long axis of a vehicle to assure complete coverage and scouring of the vehicle. Additionally, the end sections of the nozzle arrays may be pivoted so as to better impinge the front and rear surfaces of a vehicle. Tn the preferred embodiment, the stationary frames aforementioned are so fabricated as to form the primary pressure vessels used for liquid storage.
