How do plastic outdoor chairs handle exposure to automotive exhaust fumes?

Plastic outdoor chairs are designed to withstand various environmental factors, including exposure to automotive exhaust fumes. Most high-quality plastic chairs are made from UV-resistant materials like polypropylene or polyethylene, which help prevent degradation from pollutants and sunlight. While occasional exposure to exhaust fumes may not cause immediate damage, prolonged contact can lead to discoloration or surface weakening over time. To maintain durability, regularly clean chairs with mild soap and water to remove chemical residues. For areas with heavy traffic or frequent exhaust exposure, consider chairs labeled as "high-density" or "industrial-grade" for better resistance. Proper storage during extreme conditions can also extend their lifespan.
