General cleaning of your Sunbrella custom window treatment is similar to cleaning Sunbrella upholstery.
Never submerge your window treatment in any liquid.
To clean, use a low-suction handheld vacuum or gently dust with a soft, clean cloth or feather duster. For spills, blot with a dry, clean cloth, then clean with Sunbrella Clean™ Multi-Purpose Fabric Cleaner or a mild soap-and-water solution.
