A degreaser actually did the trick. Looks much better now.

Hmm, maybe I should have put this in Washing/decontamination? I am really just not sure what to do with the matte finish.

So my dad has a black RV that has some matte black paint (not vinyl graphics) on the lower potion of the RV. The Fiberglass upper is glossy black (the whole thing is fiberglass). The upper portion was waxed and after a rain the bottom portion got a wax like coating on it that is streaky from where it washed down from the top. A large portion of the bottom now has a milky colored coating on it. I ordered him some Chemical Guys Matte soap (‎CWS_995_16) to try but no luck. Any suggestions on what to do to correct the issue?
