Mold on the bottom side of the canvas top

[relentless1996]

I have a 370 Sundancer with tan canvas. I have mold on the bottom side and its a problem to clean off.
Any ideas form the group what product works then best.

I've used crazy clean with a magic eraser

If it's regular Sunbrella, scrubbing with white vinegar and Spray 9 has very effective for me.

If it is the rubber-lined water proof Sunbrella, I'm found it very difficult to get the mildew stains out of it. Spray 9 has reduced them but not removed them.

Either way, use the white vinegar with your cleaner of choice. It kills the mildew and it's spores.

Spray 9?

Star Brite mold and mildew remover worked for me

Best cleaner to have on a boat IMO. My uncle was a distributor for Knight Chemical and turned me onto it back in the '80s. Its the only cleaner of its type I use, at home, at work and on the boat.

We have Sumbrella & had the same issue. We used Kanbera gel to kill the mold & Dow bathroom cleaner to clean the dead mold. No spots left either. Did it late last summer, hasn't been back yet. Left the Bimini up all winter.

I used 3M mildew stain remover today with remarkable results. I love it when a product works as advertised. Effortless spray on wipe off.

+1. 1 cup bleach, 1 cup mild detergent and a gallon of water.

I used Amazing Roll Off on my underside and it did a good job.

I used Simple Green (purchased from Wal-Mart not the expensive stuff from West Marine) and a magic eraser for the tough stains. Wiped off with a clean damp cloth - looks like new.

Star bright mildew remover worked with no problem. Had mildew on my cover for over 4 years on my 240. Decided to take care it one day using the star bright stuff I had on my boat from an earlier cabin leak. Came off looking like new.
