Any of you folks own a Silpat, or perhaps a knockoff? I own a couple knockoffs. The other day they were dirty, and I was also doing a load of laundry. I wondered "Why can't I just throw this thing in with my dish towels and the like?" It seemed to wash fine. I just hung it up to dry. I've done it again once since then, still with no apparent ill effects. Have any of you folks tried this? I wonder if they would tolerate small amounts of bleach in the wash?
