Here's some other alternatives
Hair or hands: gently rub baby oil, vegetable oil, mink oil, Skin So Soft, Goo Off or peanut butter on the sap. Give the oil 5 to 10 minutes to loosen the sap and wash with warm sudsy water. Repeat if needed. A nonabrasive hand cleaner from an automotive store called Go Jo also does a good job on tree sap as well as oil and grease. Rub in and give it 15 to 30 minutes to work then thoroughly rinse with vinegar and water.
Automobile: Using a petroleum distillate on a car will remove the sealant. Use baby oil or vegetable oil first and give it an hour to loosen the sap. Repeat if needed. If this does not remove the sap then use mineral oil. Rinse immediately using a damp soft cotton cloth and a squirt of liquid dish soap added. Then rinse with a vinegar and water solution followed by plain vinegar.
Clothing: Often times the oil from peanut butter will remove tree sap. Dab on a good bit of it giving it an hour to loosen the sap. Repeat if needed. If that doesn't work then use DeSolvIt found at various department stores. Always test a spot first.
Furniture or decks: same as clothing.
