Is there a 'best' way to clean these pots. I have had my set for at least 10 years. They're great, but I sometimes can't seem to get them totally clean; especially the outside bottoms of the pots. Just use whatever dish cleaner I have like Ajax or whatever.
Also, a guest put the lids in the dishwasher and I ran it without realizing they were in there. They now have a whitish type of finish on them. Anything that can be done about that?
