Mr. Clean markets a car/truck washing system that works great for about $25 and is available at Walmart, etc. It's a gun that screws on a garden hose and has a compartment to fill with their soap and another compartment that holds a filter. You first rinse down the vehicle with plain water (it has a knob to switch from plain to soapy to final rinse water) then swith it to soap - it sprays soapy water - wipe it down with a sponge, then rinse with plain water, then switch to the final rinse water. Leave the vehicle to dry - it drys fast and without any water spots, etc. We love it!! It cuts down on the time and work to wash a vehicle(s).
