Abstract
An automatic car wash with a high pressure wand moves the wand slightly back and forth when the wand is spraying to provide a direct spray at an angle to horizontal and lateral axis of the car. The high pressure wand is used only once during each car wash, the other fluids being applied by low pressure pipes and nozzles attached to an overhead gantry which moves from one end of the car to the other usually applying a different type of solution with each pass.
