Hi,

We have a TJ MAX bought Calphalon Anodized aluminum saucer pan that has
been put through dishwasher serveral times lately. I noticed large
area of discoloration both inside and out and some area simply shows
the underneath shining aluminum. When I rub my finger against the
surface, I see black/grey stuff coming off it.

I only found out online today that dishwashing a calphalon like that
is a big no no, since the pan did not have any packaging or instruction
pamphlet when we bought it from TJ Max. I dont really care about the
warrenty at this stage and just want find out: What exactly is this
black/grey stuff coming off the pan? Is it harmful to health?

Any information is appreciated.

Thanks.
