  If the pine pitch is someplace other than your hands, apply the peanut butter there, but this method works best when it's your hands that are dirty.   
Get a jar of peanut butter. Get a tablespoon. Pull out a gob of peanut butter and place it directly on your palms with the tablespoon. Rub your hands together. Wait for thirty seconds. Wash the peanut butter and pitch off with water.
