What will clean tree sap stains off vinyl boat seats(Pecan tree)?

Question

Parked boat under a Pecan tree and the sap got all over my white seats and they look nasty.

Answer 1

Petroleum products work well.  Gasoline will take it off easily and won't stain the vinyl.

Answer 2

First I'd use something heavy duty like fantastic or 409. Once the bulk is off I'd try something like clorox cleaner with bleach. try a hidden test area first. Spray it on, let it sit a minute then wipe with a VERY wet towel before you rinse. I'd use the hose to do the final rinse or at least plenty of water. If you've still got sap or stains, after rinsing you might try something like soft scrub with bleach or comet powder, some elbow grease and one of those non stick pot scrubbers that wont scratch your vinyl. Good luck
