Cleaning black stains from slide seals

[chazworth]

I have done a search for the answer, but can't find. What product do you use to clean the black mildew stains from your slide seals and other rubber pieces on your campers? Nothing that I have tried so far has done more than lighten it a little bit. Thanks.

I use Westly's Whitewall Cleaner with a cut down scrub pad. You must keep it from drying and rinse well to avoid staining camper walls. Requires some good old fashion elbow grease Works better than every other product I've tried. Good Luck.
