Sap from pinetrees can transfer to your clothing, creating an unattractive and sticky mess. You can toss some items into the washer to remove sap, but you must treat wool garments with care. Removing the sap won't do you much good if you ruin the wool item you are attempting to clean. You can remove sap from wool blankets, sweaters, jackets and even yarn with common household supplies.
Spread the wool item on a flat work surface and locate the sap stain.
Saturate a cotton ball with vegetable oil. Place the cotton ball on the sap stain and leave it there for five minutes. Use a fresh cotton ball to wipe away the oil and the sap. If the sap is gone, allow the spot to dry, then resume normal use.
If the oil does not remove all signs of sap, saturate a cotton ball with hand sanitizer and dab at the sap. Hand sanitizer will almost instantly remove all but the most stubborn sap stains. If the sap is gone completely, resume normal use.
Saturate a fresh cotton ball with non-acetone nail polish remover. Dab at the remaining sap to dissolve. Allow the area to air dry to allow the scent to dissipate before wearing or storing the item.
