Pine tree sap is a gooey substance you may come into contact with if you spend a lot of time outdoors. It can be hard to get off of your clothes, so treat the stains from pine tree sap as soon as possible. Because the sap has both an oily, waxy component as well as a pigment, treat the stain with a stain remover as well as bleach to successfully remove it.
Apply a prewash stain remover to the sap-stained areas of your clothing.
Pour a small amount of liquid washing powder onto a clean cloth and rub it into the stain. Scrub the stain with hot water. This will help remove the oily part of the sap.
Put the garment in your washing machine in warm water. Use the warmest water that is safe for the fabric according to the label instructions. Use the recommended amount of colour-safe bleach for the size of the laundry load.
Remove the garment from the washing machine to see if the stain has been removed. If not, rub a small amount of rubbing alcohol on the affected area. Wash again. Do not dry the garment until the stain is removed.
