Vinyl Boat Seats and Mildew

[davans]

i need a little help. We pulled our Supra boat out of the boathouse and pulled it home during the draw down at Sinclair. It is a new, quite expensive boat. Put the cover on it and parked it in the yard. Went to air it out and get it ready to winterize a few weeks ago and found mildew growing on the seats. It is not cleaning up with our normal cleaners.
Does anyone know what we can use to clean it up without destroying the seats?

Remove the seats if possible. Rinse with clean water, then scrub with baking soda. Then rinse/scrub with a 50/50 mix of white vinegar and water. Let air dry in the sun.
DO NOT USE BLEACH! Bleach is a base and will damage the vinyl

Good luck, I had to have my upholstery recovered on our pontoon.

We tried a baking soda / vinegar mix with poor results. I'll give it another try and follow up with the 50/50 mix. Thanks for the advise.

These have worked great until we got the mold.

I've fought that battle and lost. There's a couple of cleaners from the likes of boat US that work on light mildew, but basically once it's in there deep you're pretty much done.
