How to Removed Hardened Pine Tar From an Auto

Pine tree sap should be removed from your car as soon as possible. Pine tree sap contains terpenes, a major component of turpentine. The longer the sap is on the car, the more chances it has to damage your car's finish. Pine tree sap will harden over time, making removal even more difficult. Trying to remove a hardened spot of pine tree sap runs the risk of removing some of the car's paint, as well. Soften the pine tree sap before attempting to remove it to help prevent further damage.

Things You'll Need

  • 1 quart pan
  • Water
  • Plastic razor or old credit card
  • Mayonnaise
  • Cleaning rags
  • Acetone-free nail polish remover
  • Cotton swabs
  • Isopropyl alcohol
  • Baking soda
  • Car wax
  • Fill the quart pan with water. Heat the water on a stove until the water is very warm, but not steaming hot or boiling.

  • Carefully pour some of the warm water on the spot of hardened pine tree sap.

  • Scrape off as much of the softened sap using a plastic razor as can be easily removed. If the sap is still too hard to remove, pour more warm water on it until it has softened enough to scrape off.

  • Clean the remaining pine tree sap from the car by applying a small amount of mayonnaise on the sap. Wait for 10 minutes and then remove the mayonnaise and sap with a rag. This method is the least risky for use on a car.

  • Remove the pine tree sap residue with acetone-free nail polish remover, if it was not completely removed by the mayonnaise. Dip a cotton swab in the nail polish remover, and then rub it gently on the sap residue until the residue is gone.

  • Apply isopropyl alcohol to a cotton swab. Rub the spot of pine tree residue until it has been removed. This method can be used if the residue was not removed by the nail polish remover.

  • Wash the cleaned area with a solution of baking soda and water to neutralize any remaining solvents.

  • Apply car wax to the area that had been cleaned.
