Stains on seats

[Marcella]

We got our boat out of storage and our seats have black stains that look like they are where the cover was touching it. I can’t seem to get them off. Any suggestions?

Not sure if would do stains but have you tried Babe's Seat Soap?   I had great success with that cleaning things that nothing else would.

do you have a black cover?  There were issues with black covers causing what appeared to be staining where it was touching the vinyl.  Often times letting it sit in the sun would take care of it.

Try 4 hours direct sun light.

Direct sunlight.  They will lighten and go away
