What are the effects of tree sap on cast iron outdoor bench finishes?
Tree sap can have several negative effects on cast iron outdoor bench finishes. Over time, the sticky substance can penetrate the protective coating, leading to discoloration, staining, and even rust formation. The acidic nature of some tree saps may accelerate corrosion, especially if the bench's finish is already compromised. To prevent damage, regularly clean sap deposits with a mild soap solution or specialized cleaners. Applying a high-quality sealant or wax can also help protect the cast iron surface. For severe cases, sanding and refinishing may be necessary to restore the bench's appearance and durability. Proper maintenance ensures your outdoor furniture remains beautiful and functional for years.
