WD-40: Spray a generous amount of WD-40 directly onto the dried tree sap. Let it sit for a few minutes to allow the WD-40 to penetrate and loosen the sap. Then, use a soft cloth or paper towel to gently wipe the sap away. Avoid using abrasive materials that could scratch the window.
Rubbing alcohol: Apply a small amount of rubbing alcohol to a clean cloth or paper towel. Gently rub the alcohol onto the tree sap, working in small circles. This should help to dissolve the sap and make it easier to remove. Be sure to test a small area first to make sure the alcohol does not damage the window tint or paint.
Goo Gone: Goo Gone is a commercial product specifically designed to remove stubborn sticky substances like tree sap. Follow the instructions on the product label and spray Goo Gone onto the sap. Let it sit for a few minutes and then wipe it away with a soft cloth.
Mineral spirits: Mineral spirits are a solvent that can be used to remove dried tree sap. Apply a small amount of mineral spirits to a soft cloth and gently rub it onto the sap. Use caution when using mineral spirits as they can be flammable and potentially harmful if ingested or inhaled.
Razor blade: If the tree sap is particularly stubborn, you may need to use a razor blade to carefully scrape it off. Hold the razor blade at a 45-degree angle and gently scrape away the sap. Be careful not to scratch the window.
After removing the tree sap, clean the window with a mild detergent and water to remove any residue.
