Started cleaning today and had lots of streaks on the sides. I tried cleaning a small section with CLR and the streaks came off with ease, Label says ok for vinyl siding but don.t know about the vinyl decals.
Vinyl house siding and vinyl decals are NOT the same thing!
CLR is a very caustic cleaner I would NOT use it on any part of an RV.
Instead of trying all these cleaners NOT intended for RV's and chancing permanently ruining the finish.....buy the products that have been tested and MADE for RV's. :C

remover that
safely
and effectively eliminates black streaks. Pick it up at any Walmart store.
