Some roofs are not meant to be cleaned. The oxidized material acts as a protectant. Wash it off and it will oxidize again and again until you have no roof left. Read your owners manual.
Dawn dish washing soap is good for cleaning but only if you wax afterwards. Otherwise, use an automotive soap to wash the RV between waxes. I wax mine twice a year.
