Some readers have told us about products they use. Some of their comments are:
Turpentine or finger nail polish remover.
There is a product at the hardware store called “goo gone”. Self explanatory.
Try Lestoil. It removes tar, so sap should be a non-issue.
The guy at the GM dealer who details the cars said use alcohol. Then re-wax because the wax has also been removed and the sap will stick more NEXT time.
We have not tried any of these solutions so we do not know if they will work at removing tree sap or not. Keep in mind that all these products will remove wax along with the sap. After using them rewax that area.
