RV washing with a pressure washer. A few tips from my experience of over 25 years and 1000s and 1000s of washed trailers. I did this at campgrounds all over Wi. Use a wide tip 40 or 60 degrees. Stay at least 1 foot away from surface Use a back and forth pattern. Apply soap from bottom to top. Wash from bottom to top and then rinse top to bottom. Do not use a caustic truck wash chemical as these soaps will migrate into a Fileon type fiberglass exterior and change the color on your trailer. Run as far and as fast as you can from any Airstream trailer unless you want to buy it. A hot water washer works better than a cold water unit. Take your time. In over all my years I never had an insurance claim. The easiest way to wash your trailer is to have a mobile company come to you. Show them where the trailer is, sit on a chair, grab a cold one and watch the process. Cost will run any where from 50.00 on up depending on length. NOTE No trailer will come completely clean without some scrubbing to activate the dirt and soap. Use a soft truck wash type brush.
