Outdoor fabrics exposed to marine environments often accumulate sea salt spray, which can degrade material quality over time. To effectively remove salt residue, start by rinsing the fabric with fresh water to dissolve surface salt. For stubborn deposits, mix a solution of mild detergent and lukewarm water, gently scrubbing with a soft brush. Avoid harsh chemicals, as they may damage fibers. Rinse thoroughly and allow the fabric to air-dry completely. For long-term protection, consider applying a fabric protector designed for marine conditions. Regular maintenance prevents salt buildup and extends the lifespan of your outdoor textiles.
