Ok, I messed up. Forgot to move a blanket from the rear seat after some oil had dripped onto it. Got back today and found some oils stains on the rear seat vinyl. Tried a little Dawn, Goo Gone, Simple Green and Dollar Store Carpet Cleaner on it. Nothing worked. Anyone have any special concoctions to clean vinyl?

If its white, try some soft scrub with bleach. After that just time and sunlight and it will probably bleach out.
Don't keep trying a bunch more chemicals.

Vinyl is light grey. Hadn't thought of soft scrub. Will give it a try next week when I get up to the boat. Thanks.

+1 Soft scrub. Had some pvc tubing I used to hold up cover, fall onto white vinyl seats. The red stamping on the tube dyed the vinyl, "Made in USA" (both were), used everything you tried above, Soft Scrub was the only thing that seemed to take most of it out. The Sun and time did the rest, entirely gone in a few days on the water.

I love soft scrub. It does have bleach so use and try sparingly and don’t let it sit on the stitches as it will eat them. it doesn’t affect the colors on my stuff at all. Rinse well and condition afterwards.

Hate to say it but the best chemical is nothing...leave the boat out in the sun for a while. UV does wonders for getting rid of oil stains. We’ve had a lot of luck

Thanks for the tips. Will try them out and report back after.

Little bit of acetone or laquer thinner on a rag dab it on to get residue off. Sun does the rest.
