Rubadubdub Time for a Roof Scrub!
If we wash the roof of our 2008 Fleetwood with the Beast Wash, will it affect the protective coating on the sides of the unit?
It can, depending on the type and condition of your sidewalls. Do not mix to strong or use full strength. It’s also very important to be sure your side walls are wet and that you do not let Beast Wash or any product dry on the side of your unit. I recommend using a power washer once a year to wash your roof. This really helps get the oxidization, 1500 psi should be enough. I would never wash a roof on a sunny day. A wet, nasty, ugly day is best. Not during a thunderstorm unless you want a shocking experience!
