I love the stuff, sponge it on, watch the stains turn white like magic, then spray off with a hose. Scrubbing with the sponge on any stubborn spots usually gets everything off. Then I use some wash and wax and it looks beautiful again.

Yes, Oxalic acid IS one of the acids in On & Off...the one shown in the link is formulated specifically for use on FIBERGLASS...DON'T get it on painted surfaces or aluminum trailers...
