Cleaning Old Calphalon??
I've accumulated several old (used) Commercial Cookware
saute pans (original Calphalon, I believe). Some have
really minor scratches and stains that have ben difficult
to remove using the usual methods. This stuff is NOT
non-stick, just plain old hard annodized aluminum cookware.
The stains cannot be "felt" -- they seem kinda part of the
patina. I've been trying soft-scrub cream and powdered
cleansers with a fiber-backed sponge with some success,
but I'd like to try something stronger.
