I’m the official pot-scrubber in our household. I have a question on how clean one should scrub the outside of stainless and copper pots and pans and whether this is merely an aesthetic choice.
I note that cast iron cookware shouldn’t be scrubbed at all.
Does keeping the outsides of stainless and copper pots and pans serve any purpose other than aesthetics? For example: might heat transfer be better if the bottoms were shiny instead of blackened?
