What are the effects of de-icing salts on stainless steel outdoor bench legs?

De-icing salts, commonly used during winter to melt ice on sidewalks and roads, can have detrimental effects on stainless steel outdoor bench legs. While stainless steel is known for its corrosion resistance, prolonged exposure to de-icing salts can lead to pitting, rust, and surface degradation. The chlorides in these salts break down the passive oxide layer that protects stainless steel, accelerating corrosion.

To mitigate damage, consider using stainless steel grades with higher corrosion resistance, such as 316 stainless steel, which contains molybdenum for added protection. Regular cleaning with fresh water to remove salt residues and applying protective coatings can also help extend the lifespan of your outdoor benches. Proper winter maintenance is essential to preserve the appearance and structural integrity of stainless steel furniture in harsh climates.
