I've had good luck using hydrogen peroxide to remove mildew from painted
surfaces - don't know how it's co-exist with the fabric your 'yak's made of,
tho....

I have a foldable kayak with a interior wood frame. Having left water
in the boat for too long, a number of pieces have what looks like
mildew stain and some minor rotting. The integrity of the pieces are
fine and I am not concerned with the aesthetics. I would like to
refinish the pieces with spar varnish but I am wondering if I need to
get the mildew stains out and how to do that. A light sanding smooths
out the pot marks but doesn't get the stains out. Any suggestions??
