Abstract: A method of washing a vehicle with a gantry-type apparatus in only two passes uses the first pass to apply a pre-wash solution while subsequently brushing the top and sides of the vehicle and a second pass to initially brush the sides of the vehicle, then apply a spot-free rinse solution to the vehicle, then brush the top of the vehicle and subsequently apply a drying agent alone or mixed with a spot-free rinse. When the drying agent is applied alone, a spot-free rinse is applied separately and subsequent to the application of the drying agent.
