I use the blue dawn on the roof as others have stated. For the sides I use Turtle Zip wash and wax. It cleans good and leaves the surface pretty shinny. Even though the product recommends you wipe it down with a rag after washing I never have. That is all I used for the first 7 years we owned the rig. Finally broke down last fall and applied a paste wax. Hope it's another few years before I get to do that again. As a disclaimer I must add that my unit was stored inside the first 6.5 years we owned it but was outside in the elements for about 500 days of that time. Jim
