Perhaps a chef who has lots of experience with cookware might know when to or when not to replace a stainless pot.
I use the pot for cooking great northern beans and it has been used for maybe 60 years. It is a 4 quart Revere Ware stainless steel sauce pot with a copper bottom. I use a 3M scouring pad to clean. After cooking there is some dark discoloration and I can feel residue there but the 3M pad gets it shiny clean.
What prompts me to ask is that I have to clean it every time I cook the beans and that used not be the case so I thought I would ask before thinking about replacing it.
The same pot on Amazon used is over 100 dollars since they are no longer made and it could be worse than mine so it behooves me to at least ask.
