A lot of campers who cleaned their roofs used Spic N Span powder said it worked the best. The year we bought our 1st camper you could not find it any more. Today local Home Improvement Store-Stine's had some on the shelf, a 27oz. box for 5.99. Their website also shows its available. Stine Home + Yard : The Family You Can Build Aroundâ„¢
Hope this helps a fellow camper.
For mildew stains, Tilex Mold & Mildew Remover works well, too. It can be hard on the finish on the sides of the camper, though, so it is imperative to keep the sides rinsed down as you go if you use it.
