I normally just use the water hose and a nozzle. I spray a while scrub a while. Yesterday we had a good day of playing in the mud, and my yellow foreman was brown. I stood it up on the back rack and used the pressure washer on it. The pressure washer cut my clean up time down from about an hour to about ten minutes. Does anyone know of any problems I might encounter by using a pressure washer on it, or by standing it up on it's back rack for a prolonged period of time? I just turn the fuel off put it in gear, lock the parking brake, grab the front bumper and flip it up, once the back rack touches it will stand by itself if the ground is level.
