  • Someone above mentioned oxidized paint---Years ago I had a DP like that and someone mentioned using Red Max floor wax on it. Had to be careful to not have any bubbles but after going over it 3 times it shined like new. I did it each spring and it left here looking like new and included a gallon of that wax. I think it has a different name now days.
  • Thanks folks, the Rainex seems to be what the companies spray on as they wash the rigs in the RV parks. Will try that too.
  • I use Rainex car wash on cars and RV. Seems to, as advertised, reduce water spotting. Will follow up, but not every time with Wash Wax All.
  • Thanks all for the suggestions and opinion.i think I will run to Walmart or Costco and pick up some carwash soap and zip wax.

    Whatever is on sale at WalMart, Sam's or Costco.
  • What rV are you washing/waxing? If it's a unit with oxidiation on the fiberglass you will need more than soap and wax.
  • For years we used dish soap on our vehicles and thought it was great. Then we did a consult with a paint manufacturer before having our RV painted in Mexico. Turns out the best paints are high in lipids. What is dish soap designed to remove??? Fat!!!

    We changed to cheap car wash soap and it is good stuff.

    Wax is the kind of thing to research on line, with things like Consumer Reports. Until we sold ours in the last couple of years, every winter, while we were here in Mexico, I'd hand wax every inch of the RV. I'd choose a small chunk every few days, wash it, and wax it with Turtle Wax. Cheap, readily available and when I did it the next year, you could still tell the wax was present.

    It also depends upon how much energy you will actually expend putting on wax. If you tend to hate the job, buy a car wash with wax in it!

    We had a fully painted metal roof, so it got waxed too. By doing literally all of it, any little problems could be seen and taken care of.

    So, yes, use car wash, not dish soap, and do your homework on the wax. All just my opinions.
