You can take it to Custom Canvas in Montclair and see Ron. We take ours to him and looks brand new. I believe that's where GT sends his stuff as well.
We've always just used air to blow of the big dust and then a very light rinse with the hose, that way the sunbrella keeps it's treatment and will continue to bead water, i guess you could scotch gaurd the thing after washing it though. Cold Water Only!!!!!

Spray it down with fantastic or equivlant and throw it in a hot tub for a while, then hang out to dry!! Works great
