Are WPC benches prone to discoloration from air pollution?

WPC (Wood Plastic Composite) benches are popular for their durability and low maintenance, but many wonder if they are prone to discoloration due to air pollution. While WPC is resistant to many environmental factors, prolonged exposure to pollutants like smog, industrial emissions, or acid rain can cause gradual fading or discoloration over time.

Unlike natural wood, WPC benches are less likely to develop severe stains or uneven discoloration, thanks to their synthetic composition. However, in highly polluted urban areas, surface discoloration may occur. Regular cleaning with mild soap and water can help mitigate this issue.

To maintain the appearance of WPC benches, consider applying a UV-resistant sealant or placing them in shaded areas to reduce exposure to pollutants. With proper care, WPC benches can retain their aesthetic appeal for years, even in polluted environments.
