Winnebago says "granulated household cleaner mixed in a solution with water." (what "solution" with granulated cleaner wouldn't use water?)

" Regardless of the type of rubber roof you have, NEVER use any cleaners or conditioners that contain petroleum solvents, harsh abrasives or citrus ingredients. These types of cleaners can cause permanent damage to rubber and vinyl surfaces. The first indication of rubber roofing coming in contact with petroleum products is a bubble forming. The thickness of the rubber is compromised and chances are it will never adhere to the roof decking again."

For this very reason, I use only RV rubber roof cleaner and conditioners and don't take chances with anything else. Yea, it's more expensive than Spic-N-Span, but it's also made to put back into the rubber those elements that mother nature strips away.
