What are the effects of saltwater spray on canvas outdoor bench durability?

Saltwater spray can significantly impact the durability of canvas outdoor benches, especially in coastal environments. The high salt content in ocean mist accelerates fabric degradation, causing fading, stiffness, and eventual weakening of fibers. Prolonged exposure leads to mold growth, corrosion of metal frames, and reduced structural integrity. To extend bench life, choose marine-grade canvas, rinse regularly with fresh water, and apply protective treatments. Proper storage during storms and off-seasons also helps mitigate saltwater damage. Understanding these effects allows for better maintenance of outdoor furniture in seaside locations.
