What are the effects of tree sap on canvas outdoor bench fabric finishes?

Tree sap can have several negative effects on canvas outdoor bench fabric finishes. When sap drips onto the fabric, it can create sticky, hard-to-remove stains that may attract dirt and debris. Over time, the sap can penetrate the fabric fibers, causing discoloration and weakening the material. Additionally, some types of sap contain acids that may degrade the fabric's protective coatings, reducing its durability and water resistance. To minimize damage, it's important to remove sap promptly using gentle cleaning methods, such as rubbing alcohol or a mild soap solution. Regular maintenance and protective treatments can also help preserve the fabric's appearance and longevity.
