Mildew

Ok, I have a 94 Itasca, W/fiberglass side panels. Has picked up
mildew from where I store it. Spent 4 hours washing and can still see the stuff. What works on getting mildew off, without killing yourself.

On a former motor home, we used a strong solution of Oxiclean. We made a paste out of it and put it on with a brush and let it set for about and hour then scrubbed it off and rinsed liberally.

That was on the molding which turned very black with mildew, on the entire sides, a strong solution (not quite paste, more like thick soup) with a rag may work better
