Cleaning Black Streaks off of white Trailer

Reliable RV Cleaner works like a charm. Been using it for years. Spray it on, wipe it off, no more streak. Every streak, any streak. You should wax after, but it won't hurt the finish and is made to do the whole trailer if you wish.

Catch them early and they're pretty easy with most anything. Let the sun bake them and it's not easy. Steak remover works for me but not easily

We use Awesome from the Dollar store on our aluminum siding with good results.

Orange Awesome from the Dollar Tree and a good long handled brush. We have the one that belonged to my father but I assume they still make them. You can reach the top of the trailer with it.

Thanks
