As a result of 10+ years of use, I have a very badly stained All-Clad copper core fry pan. The cooking surface is fine, all of the staining is on the outside.
I've had such good luck cleaning my Le Creuset with oven cleaner that I would like to try it on the All-Clad.
Is this a mistake?
And yes, I've tried Barkeeper's Friend on it. No bueno.
