Tree sap is a sticky, resinous substance produced by trees to protect wounds and seal in moisture. It can be a nuisance to get on your hands, as it is difficult to remove and can be irritating to the skin.
There are a number of ways to remove tree sap from your hands. Some common methods include using rubbing alcohol, hand sanitizer, or vegetable oil. You can also try using a commercial product specifically designed to remove sap from skin.
