I think damage to anodized (hard oxidized) aluminum in a
dishwasher is probably due to the highly alkaline nature of some
dishwasher soaps which will dissolve aluminum oxide if only
slowly. Calphalon used to sell a slightly abrasive cleaner for
the pots which would remove persistent deposits if not
accidentally burned-on grease. I haven't seen the cleaner in a
while but it's no great loss since Bon-Ami cleaner seems to work
as well.

Incidentally, it's an observable fact that you *can* scratch
Calphalon pots with utensils :-(
