On behalf of my mom...she was just wondering about some discoloration. She had a stainless-steel quart pot (Ikea, I think) that she uses mostly for boiling vegetables. It's nine months old. The inside of the pot has gotten discolored, (the last thing she boiled in it was carrots) and was just wondering if the discoloration was from natural aging or something else i.e. the cookware itself. Any insight appreciated!
