Are polyethylene sculptures resistant to damage from bird droppings or pollutants?

Polyethylene sculptures are widely used in outdoor art installations due to their durability and versatility. One common concern is whether they can resist damage from bird droppings or environmental pollutants. Polyethylene is a robust, non-porous material, making it highly resistant to staining and corrosion caused by bird droppings, acid rain, or other pollutants. Unlike metals or porous stones, polyethylene does not absorb moisture or chemicals, preventing long-term damage. Regular cleaning with mild soap and water can maintain its appearance. However, prolonged exposure to harsh pollutants may cause slight discoloration over time. For optimal longevity, applying a UV-resistant coating is recommended. Overall, polyethylene sculptures are a practical choice for outdoor art, offering excellent resistance to common environmental hazards.
