I own a 2010 Puma 26RLSS (Aluminum sided) TT.
About a week ago, I was giving the TT a good wash. (I live in the south, so it's the climate isn't too cold for this task.) I had some black streaks that the Gel Gloss Wash/Wax wouldn't get off, so I bought Thetford Black Streak Remover and they came off like a champ. EXCEPT...
In two areas (hand-size) it appears as though the black streak remover discolored my white aluminum siding. It's streaky and a light bluish-purple color. The finish is still smooth (doesn't appear to eaten through the pain), but I can't seem to get the stain out.
Any advice? How hard can I scrub? Should I scrub? I've googled this to death, and I can't seem to find any guidance on how to address this blemish.
I'll try to post a picture tomorrow.
