Acids are never a good way to clean any metal cookware, causes
microscopic pitting that will cause metal to decay from the inside,
same as dental caries.

I never heard of "brass-bottomed" pots or any brass pots unless you're
talking spitoons.

That's not true, surface condition has nothing to do with 'heat
transmission'. A dark (and rough) surface *absorbs* heat better,
a light shiny surface reflects heat away... remember that next you use
aluminum foil, it's purposely manufactured with a smooth shiney
surface on one side and a dull rough surface on the opposite side,
it's made that way for reasons that are understood by those who know
how to cook... most people cook with aluminum foil back asswards. Most
people have no idea how to maintain metal cookware, smooth and shiney
is the worst condition possible... smooth shiney exteriors reflect
heat away, smooth shiney interiors cause foods to stick.
