Re-treating the fabric
As part of the finishing process, Sunbrella fabrics are treated with a fluorocarbon finish, which enhances water repellency. This finish is designed to last for several years, but must be replenished after a thorough cleaning. Based on test results, Glen Raven recommends 303 High Tech Fabric Guard™ as the preferred re-treatment product for Sunbrella fabrics.
Fabrics should be re-treated after thorough cleaning or after five years of use. For more information on re-treatment products, please visit 303products.com.
*Synthetic fabric heat settings normally do not exceed 150°F/66°C.
Applying 303 High Tech Fabric Guard
303 should be applied to Sunbrella fabrics after each thorough cleaning, which typically removes the original finish and reduces the fabric’s water repellency.
Clean Sunbrella fabric, using one of the cleaning methods.
Allow Sunbrella to completely air dry.
Apply 303 Fabric Guard in a well ventilated area following instructions on the container.
Apply 303 in a thin, even coat and allow fabric to dry completely.
Apply a second thin, even coating of 303. (Two light coatings are more effective in restoring fabric water resistance than a single heavy coating.
A 15-ounce bottle provides coverage of up to 50 square feet of fabric.)

Professional awning cleaners
You may have access to professional awning cleaning firms. In evaluating the services of a professional firm, you should inquire about a firm’s experience in working with Sunbrella fabrics and knowledge of cleaning and re-treatment requirements. DO NOT dry clean Sunbrella fabrics.
Protect the area around the Sunbrella fabric when using a bleach solution – bleach may discolor non-Sunbrella fabrics. Always rinse Sunbrella thoroughly to completely remove bleach.
Sunbrella air dries very quickly. Machine drying is not necessary.
If fabric has some wrinkling, use an iron, if necessary, but only on the synthetic* setting. As some irons exceed the recommended 100°F/38°C temperature on the synthetic setting, test a small inconspicuous area before ironing entire piece.
DO NOT use a steamer or iron set to steam setting.
Use of bleach and/or advanced age of the fabric application may impact the deterioration of the sewing thread and other non-Sunbrella components.
