Why is aluminum outdoor seating prone to chalky oxidation over time?
Aluminum outdoor seating is a popular choice for patios and gardens due to its lightweight, durable, and rust-resistant properties. However, over time, it often develops a chalky white oxidation layer. This occurs because aluminum naturally reacts with oxygen in the air, forming a thin oxide layer that protects it from deeper corrosion. When exposed to moisture, UV rays, and environmental pollutants, this layer can degrade, leading to a powdery, chalky appearance.
Factors like humidity, salt air (in coastal areas), and acidic rain accelerate oxidation. Regular cleaning, protective coatings, and proper storage during harsh weather can help minimize this issue and extend the lifespan of aluminum furniture. Understanding these causes allows for better maintenance and preservation of outdoor seating.
