I upgraded my prior Calphalon cooking set to their newer hard-anodized line; handles stay cool vs. what I had prior from 10 years ago. They recommend Barkeeper's Friend and included a small sample of it with my purchase at Macys. Anyone have any better ideas? I didn't like how it got stale smelling after awhile...not what I need in a cleanser. Is Comet OK as it was with the older Calphalon hard anodized line?
