The only solution that Sunbrella and other fabric manufacturers recommend for restoring materials' lost water repellency is 303 Fabric Guard. By producing a strong barrier, 303 Fabric Guard significantly improves water and stain resistance, guarding against stains that are based on both water and oil. Apply it on Dacron sails, awnings, boat covers, and fabric chairs, among other surfaces. For many years to come, keep all of your favorite textiles clean and crisp.
