This works great. Just spray it on those stubborn mildew stains on you boat seats and wait. It clears up right before your eyes. Wipe it clean with wet rag, dry it and then don't forget the conditioner to keep the seat perfect for the life of you boat.

Works Great on my Boat!!

When it is time for spring cleaning on my boat I always use RMR-86M. It removes all mildew stains from my cushions and other areas on my boat. I've tried alot of other cleaner over the last 10 years and this one works this best in the marine environment!!!!

86 your Mildew stains

I tried everything on my RIB to get rid of the mildew freckling. Nothing worked except RMR-86M. I am so happy someone suggested it. I was so doubtful, because of so many fails. I couldn't believe it when they disappeared.
