The system for cleansing exterior surfaces of vehicles has horizontal arrays of plural zero degree solid stream nozzles in spaced relationship along the linear length of the arrays. The zero degree nozzles are at an angular orientation with respect to the linear length of each array such that the solid streams emitted from them are form 40 DEG up to about 80 DEG from the linear length. Each array is equipped with elements for oscillating the array in a direction transverse to the linear length thereof. The system includes elements for effecting relative linear motion, lengthwise between a vehicle undergoing treatment and the horizontal oscillatable arrays, with each array laterally parallel to a side of the vehicle. Ends of a vehicle as well as sides can be cleaned with the angularly impacting solid streams from the arrays during the relative linear motion even though the arrays are laterally parallel to the length of the vehicle.
