Are polyester fabric outdoor bench covers prone to damage from ice-melting salts?

Polyester fabric outdoor bench covers are known for their durability and resistance to harsh weather conditions, but how do they hold up against ice-melting salts? These salts, commonly used in winter to prevent ice buildup, can be corrosive to certain materials. Fortunately, polyester is relatively resistant to salt damage due to its synthetic, non-absorbent nature. However, prolonged exposure or high concentrations of salt may eventually weaken the fabric over time. To extend the lifespan of your bench covers, rinse them periodically to remove salt residue and consider using a protective spray designed for outdoor fabrics. For optimal performance, choose high-density polyester covers with UV and water-resistant coatings. While not completely immune, polyester remains a reliable choice for winter protection compared to natural fabrics like cotton or canvas.
