Ever noticed those ‘rainbow stains’ at the bottom of your stainless-steel pots and pans? Have you tried to get them out by scrubbing so hard that your hands hurt, and you still fail? Is it the quality of your pots and pans? Or maybe your dishwasher is not doing its job well? Let’s address your doubts around this kitchen mystery.
What Are They?
These mystery rainbow stains are called ‘heat tints’ and are caused by the material’s exposure to oxygen. Stainless steel contains traces of chromium – a metal that helps protect your pans from corrosion and rusting. When chromium is exposed to air and heat, a thin, almost transparent, and slightly rainbow-coloured protective layer appears on your pan, like a little science gimmick.
Are They A Health Hazard?
This multi-coloured marvel/ eye-sore (depending on the way you see it) is super innocent and harmless and has nothing to do with the quality of your utensils or cleaning methods. These stains do not come in the way of functionality. You can continue using them for simmering, boiling, searing, frying and sautéing. It won't affect the quality or the flavour of the food.
How Do You Get Rid Of Them?
Before we get into this let me be clear – you do not need to get rid of the stains. The utensil will still work perfectly, and it's completely safe to use. But if you are used to everything around you being spotless, there’s a way.
1. Spray a mixture of white vinegar and water in a 1:1 portion on the pan.
2. Make sure you cover all the stains and keep them aside for 10 to 15 minutes.
3. Use a non-abrasive sponge to wipe away the rainbow stains.
