2What’s with the Rainbow Stains on Stainless Steel Pots?
If you’ve ever come across this odd, colorful film on your stainless steel pots, you’re not alone. It’s all down to science! Stainless steel pots often contain chromium, a sturdy metal, which helps keep them from rusting or corroding. Mix oxygen and chromium, and you’ve got yourself a little rainbow show all to yourself. It’s basically a thin protective layer that changes color when combined with air and high heat. But don’t worry…it’s completely safe.
