While rubbing alcohol is the fastest and easiest way to remove tree sap from clothes, the oils in peanut butter or cooking oil, like olive oil, can also break down sap, believe it or not!
Use a dull knife to scrape off as much sap as possible. Apply a small amount of peanut butter or cooking oil to the sappy spots, and work it in with your fingers or a clean rag.
Pre-treat the stains with your favorite natural laundry detergent, then wash your clothes as usual in the washing machine.
