From Sunbrella manufacturer Glen Raven, here is a link to information about caring for and cleaning Sunbrella products. The page offers information, videos, and *.pdf documents about maintaining upholstery, marine, and awning fabrics. For stain removal on Sunbrella, check out the stain removal tips page.
After a thorough cleaning, Glen Raven recommends 303 High Tech Fabric Guard as the preferred re–treatment product for Sunbrella fabrics. Its available for purchase at our shop.
