How can I clean and polish RV fiberglass that has lots of oxidation?

They make cleaners and polish for RV's. Check out an RV place or even a boat dealer for what would be recommended for fiberglass RV's.

Maggie, There is a special fiberglass cleaner, just for fiberglass. You can purchase it at Home Depot or Lowe's. This is a cream like Soft Soap, that you apply in the same way. Read the directions, and I don't know the name of the cream. Aloha!

If you live in Indiana, there is a product available called "Bypas" that is used in groceries to clean blood out of the meat counters. It is amazingly good to wipe down RV siding (my parents used it for well over 15 yrs while working on the road). Wish it was available elsewhere!! Costs less than $5 usually and comes in 16 oz.

Hello Maggie this 3m product made our boat look like new! Check out reviews and QA to see if it might help your situation,

Hope this helps.
