I know - me bad!
I have an entire set of Calphalon cookware, the majority is the hard anodized commercial pieces that came out in the early 80's. I have never had a problem with any of the pieces. I recently purchased a new Calphalon hard anodized 3-1/2 Qt. pot. I was in a hurry one night and I put it in the dishwasher. It came out with this white hazy looking film all over the outside and inside. A green scrubby didn't remove it. Have I ruined my pot?
P.S. I don't think the Calphalon made today is near the quality of the old stuff.
