What you need to know about the discoloration of stainless steel when heated?
Although it will not have any effect on your food, it can be unsightly and annoying.
Our pots and pans mean a lot to us. I mean, when we spend so much time with them
in the kitchen, how can they not?
We always hope that they will always shine like new, but this is usually impossible.
But that doesn't mean we haven't tried the method of cleaning the bottom of the pot
and the scorched pot bottom is a technique we have happily tested.
But what about the strange discoloration of stainless steel due to heat?
Fortunately, the strange iris on your cookware is easy to repair.
What happened to the rainbow stains on the stainless steel pan?
If you have encountered this strange colored film on a stainless steel pan, you are not alone.
It all boils down to science!
The rainbow stain on stainless steel is what we call "heat tint."
Stainless steel contains a small amount of chromium in it to help resist corrosion and rusting.
...
Basically, when stainless steel is heated to high temperatures, the oxidized layer can
thicken, causing a rainbow tint.
It's 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.
How to remove stains?
Yes, your pots are totally safe with the rainbow residue.
However, it may still be a bit too unsightly for your clean kitchen taste.
That’s OK—we’ve got the solution.
As you may already know, the answer is…vinegar!
We basically use vinegar to clean everything.
Take some diluted white vinegar and scrub with a non-abrasive sponge.
Then after putting the vinegar into the stainless steel cookware thoroughly,
you only need to rinse and dry it.
The acidity of the vinegar will break down the oxidized rainbow layer, making your
stainless steel cookware look silvery best.
