It's a pan I inherited and did not know it was not dishwasher safe. After a couple of cycles in my dishwasher, the black outside coating has started to come off. The cooking surface and the handle still look fine. I called All-Clad customer service, but the woman I spoke to was unable to answer my questions. She suggested I send it to them so they can look at it, but I would rather not.
So, here are my questions:
Has this happened to anyone? Is the pan still good, or have I ruined it? What is the function of that black coating? Other than washing away the black outside layer, is there any other reason I shouldn't put it in the dishwasher?
