WHY is a dishwasher bad for my Calphalon???
I understand that Calphalon anodized aluminum pots should not go in the dishwasher. Since a houseguest unknowingly put one of my in a few years ago, I've seen firsthand how it turns white. What I don't understand is WHY??? the stuff is otherwise pretty indestructible and I use all sorts of harsh abrasives on it, cleaning my roasting pan with comet or barkeeper's friend all the time.
