It's time to pull the boat out of the water, bring it home for a few days, and do the spring cleaning. As always, being covered and used sparingly over the winter has left the seats with a little mildew.

Question: Does anyone have good experience with any product that will actually prevent or reduce the occurance of mold and mildew on vinyl?
This product works for me. You have to leave your topside exposed for a
month, or so, and cover it later. It will keep working for several
months before you need to re-apply it.

This works well for a quick clean but it is tougher on the fabric and
stitching:
