Vehicle washing method

Abstract

A vehicle washing system includes an arch frame that moves on rails over and along the length of a vehicle. A rack support arm is rotatively connected to a horizontal cross member of the frame and a rack with vertically depending cleaning strips is connected to the support arm. Prior to activation, the vertically depending cleaning strips are located on the side(s) of the frame so that an unobstructed vehicle entry and exit way is provided. Once activated, the cleaning strips are rotated into position in contact with the vehicle. Thereafter, the rack support arm is reciprocated to move the strips back and forth across the vehicle as the frame moves. A dual-rod cylinder provides movement of the rack support arm into an active position with the cleaning strips in contact with the vehicle and also provides the reciprocating action. A rocker panel cleaning assembly is provided to clean the sides of the vehicle as the frame moves and the rack support arm reciprocates.
