Tree sap is one of the most common causes of damage to vinyl boat seats. It can get on vinyl seats while the boat is uncovered or if a small portion of the cover comes loose, exposing the vinyl.
The real problem with tree sap is that it melts easily into the seats in the sun or hot weather, making it next to impossible to clean off. It is best to take preventative measures to keep tree sap off your boat whenever possible and to clean it off quickly if it does become a problem.
Keep tree sap off your boat seats
Keep your boat covered when not in use. It is also a good idea to do a thorough check of your boat when you pull it out of winterization. Tree sap has a sneaky way of getting in through even the tiniest of holes in your boat cover. Also, if you leave your boat uncovered for a while to dry out after use before covering to prevent mildew, do a quick inspection before you put the cover on.

It is best to use a citrus-based cleaner without bleach to clean tree sap off your vinyl seats. If that isn’t working, and you need something stronger, try using methyl hydrate.
