Hello Houzzers,
I have seven Sunbrella cushions on my deck that I have had for many years. They were starting to get dirty and some mildrew. I took the covers off and washed with bleach. They washed beautifully. I looked online and saw that Sunbrella recommends 303 High Tech Fabric Guard. I put two coats on all cushions. This product had excellent reviews. It rained the other night and all cushions are FULL of water. ???? I never had this problem with them before I washed and treated them! Does anyone have any ideas? I wrote the company but didn't get a response. Thank you in advance!
