Stainless steel cookware is a true thing of beauty and they're great for sauteing, broiling, boiling, and you can even use them in the oven. This versatility is what makes them a kitchen staple, yet extra care to maintain their shine is needed.
Most stains on a stainless steel surface are handled easily by wiping out the excess oil with a spatula or paper towel. Do this before deglazing the pan with hot water while it's cooling to avoid thermal shock.
Experts suggest that you should not use the dishwasher and instead opt for submerging cookware in boiling water with soap or baking soda to loosen grime. The last step will be a splash of white vinegar and a sponge to remove any stains.
If there are any of those pesky hard water stains you can combine boiling water and white vinegar to soak the cookware. This works because vinegar (acetic acid), reacts with elements like calcium found in hard water stains by converting them chemically so they can dissolve into the water.
