What are the effects of acid rain on polyethylene and PVC outdoor ottomans?

Acid rain can significantly impact polyethylene and PVC outdoor ottomans, leading to material degradation over time. Polyethylene, while generally resistant to moisture, may experience surface erosion and color fading when exposed to prolonged acid rain. The acidic compounds can weaken the polymer chains, making the material brittle and prone to cracking.

PVC ottomans, though more chemically resistant than polyethylene, are not entirely immune. Acid rain can cause discoloration, surface pitting, and a loss of gloss in PVC. In severe cases, the plasticizers within PVC may leach out, reducing flexibility and increasing the risk of fractures.

To mitigate damage, consider applying protective coatings or storing ottomans indoors during heavy acid rain periods. Regular cleaning with pH-neutral solutions can also help preserve their appearance and structural integrity. Both materials remain popular for outdoor use, but understanding their vulnerabilities ensures longer-lasting furniture.
