Exterior WASH
 

Just a simple ? What is a good product to use to wash Kool seal roof and fiberglass sides and end) caps.... 2000 21TD
I uses( Mean Green from Dollar General..Think its a (Diluted Simple Green) maybe its too harsh...Just wanted to kick around some others Favorites

I wouldn't worry too much about the detergent you use. I think Simple Green in water or a good automotive detergent such as Meguiars Gold Class would be fine. Some people have used pressure washers too - that's something I'd be careful with. If you have a pressure washer that can deliver a fairly gentle spray, it would be ok.

I use dish soap and haven't had any issues. They make a cleaner for rubber roofs but I think it's pretty high dollar.

This is what we were told to do before DH was going to coat our metal roof. Go to your local hardware store and purchase a product like soilax. It is a cleaner for walls that will not leave a film. You can buy a cleaner for your specific roof type. A spray product will last for many washings. We just use a car wash that has a little wax in it. Bought at Walmart. This is for the body of the trailer. I had a yellow streak and our body shop person told me to use oven cleaner. It removed the yellow. My guess it was from a rusty screw that may be under the roof to body strip.
