To remove tree sap from a car, start by washing the affected area with warm, soapy water or a high-quality car wash soap to soften the sap. If the sap is fresh and still sticky, this might be enough to remove it. For tougher sap spots, apply a sap remover product or use diluted rubbing alcohol (isopropyl alcohol), hand sanitizer, or a tar and glue remover specifically made for automotive use, but always test on a small area first. Avoid harsh chemicals like acetone, nail polish remover, or scraping with razor blades, as these can damage the paint. After treatment, rinse thoroughly and apply a protective wax or sealant to prevent future sap adhesion. Parking away from trees and washing sap off promptly helps prevent buildup and damage.
