WHY is a dishwasher bad for my Calphalon???

xavier Oct 30, 2006 12:38 PM

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.

    All aluminum pans should not go in the dishwasher as the detergent is heavily chlorinated and acts as a corrosive on the metal. Stainless steel does well in the dishwasher, but most other cookware materials don't.

    To restore the finish on your pan, try Calphalon's Dormond cleaner.

      I think it's not so much that it's chlorinated as caustic. The high pH and aluminum don't get along well.

        Yes, you are right Ted. It's been too many years since my stewarding days :).

          No biggie. Chlorine would do in the stainless, too.
