Washing your vehicle at a self serve car wash can save you some money over washing it at an automatic drive thru car wash. To use a self serve car wash you'll need to deposit your coins into the coin mechanism, select your options for what type of wash you want and once the spray nozzle starts to spray soapy water use it to spray your car clean.
