A mate of mine lost his mast to the bottom of the Swan River with his jib and main, was in fine mud for a couple of weeks, he used a karcher and they came up a treat. That said obviously there were no rust stains.
Probably soft sails. The problem with a pressure cleaner is it would possibly ruin a hard or heavily resin filled sail. Commercial sail cleaning companies use a tumbler style washer which can have the same effect. Best bet is to treat the sails gently.
