If your stainless steel cookware looks like it may be reaching the end of its lifespan, we encourage you to give it a good cleaning first. More often than not, food, stains and burn marks accumulate on your stainless steel pots and pans because you're not cleaning them properly. Luckily, with a bit of research, learning how to care for your cookware correctly is easy.
If you've tried all of the above cleaning methods and your stainless steel cookware is still scratched, stained, dented, or rusted beyond repair. Then you'll want to replace it. This is especially so if your pots and pans have been scratched to where the material beneath is showing.
Stainless steel cookware with stains never looks great in a kitchen. If there are stains on your cookware that you've tried to remove and couldn't, the chances are your pan has overheated. To get these stains out for good, use vinegar and a dish brush to scrub at the stains gently. If you don't have vinegar on hand, use your pan for cooking something acidic like tomato sauce which may help improve the discoloration.
