ABSTRACT:
An automotive wheel washer comprising a circular conduit having a diameter of approximately 12 to 20 inches and further provided with a plurality of circumferentially spaced nozzles which direct cleaning fluid and chemicals laterally of the wheel washer and toward the adjacent wheel in an inwardly converging fashion. An additional 360° center nozzle produces an outwardly diverging spray pattern which, in combination with the plurality of spaced outer nozzles, is effective to cause direct application of cleaning chemicals to all surfaces of a wheel and reduce the shadowing effect caused by intricate wheel structure patterns. Foaming is created by a porous material in a foaming chamber serving as a common inlet to all nozzles and further having a high pressure air inlet. The circular conduit may be made of plastic or stainless steel or any of a number of essentially equivalent materials.
