Won't Clean

Yellowing can sometimes be floor wax someone used on the rv. it yellows in the sun, a strong ammonia solution and a brush can help remove that.

I have good luck with Simple green and 303

If it's the sun side, look closely, you're probably seeing the fibers of the fiberglass. After many years of being hit by the sun, the fiberglass is just not repairable. If you've tried many products already, yo will not improve the look. The best you can do is to keep it waxed and shiny. The color won't come back.

I used a mr clean eraser on my old MoHo. worked like a charm.

Try tilex once and get back to me, the bleach in it instantly removes all that with a brush, leaving a clean surface on fiberglass and the plastic on the roof. the result is dramatic.

We got our Winnebago used and has the same stuff but the edges of the decals are going bad. When boat place said to wet sand it but that would tear up the decals. We tried beekeepers, 3 different cleaner waxes, rubbing compound, and polishing compound. Some with a buffer and some without. The part I washed and then scrubbed with 00 steal wool and then waxed looks best but like said above it will take a lot of elbow grease to do the whole thing.

No wax, rubbing compound, etc. is going to remove the black mold/mildew. The fiberglass surface is not smooth like gelcoat on a boat. The stains are imbedded down in the fiberglass. Steel wool or wet sanding the surface to make it smooth is one way but it's a ton of work. As I said earlier, Zep mold/mildew stain remover cleans it right up. Then a coat of wax so it can't form again. Our MH doesn't look like it has full paint but it sure looks a lot better.

TR3 wax / polish / restorer (comes in a can and is a thick liquid paste). Been around for years and will do an amazing job on your gelcoat and fiberglass. It is available at most auto supply stores. Does require rubbing on and rubbing off but does not require very heavy effort to apply.

Tilex, you will be amazed

And before you do that, go to WalMart and get a bottle of "Formula 409". It sure SMELLS like the same stuff.....and I suspect that it IS.....at about half the price or less.
