Is it normal for stainless steel pans to discolor?
Overheating or allowing cookware to boil dry can cause yellow, brown, dark purple, blue or rainbow tints on the stainless steel surface. Although harmless, these tints can spoil the appearance of the pan. To remove this discoloration, use a products like Barkeepers Friend® and a non abrasive cleaning pad.
How do you clean discolored stainless steel pans?
What causes discoloration on stainless steel?
The oxide layer is what makes stainless steel what it is. Some abrasive chemicals that can endanger your stainless steel are salt, chlorides, and bleach. These can cause your stainless steel items to discolor rapidly.
How do you restore a discolored stainless steel finish?
If harder stains or rust remains, sprinkle baking soda or another non-abrasive scrub cleaner on a soft, damp cleaning cloth, mixed with liquid soap. Clean problem areas gently, going with the grain of the stainless steel. Spray the surface with vinegar-water mixture or glass cleaner and wipe again.
At what temperature does stainless steel discolor?
Different colors occur when Stainless steel is exposed to temperatures ranging from 700 to 1200 degrees Fahrenheit.
Why does my stainless steel pan look rainbow?
When chromium and air mix, a protective layer is formed on your pan. More simply put, when Stainless Steel is heated to high temperatures, the oxidized layer can thicken, which causes a rainbow tint.
How do you fix discolored metal?
Mix equal parts warm water and white vinegar. Use a toothbrush to scrub the tarnish off the metal with the mixture. Combine ½ cup of vinegar, 1 teaspoon of salt, and ¼ cup of flour for stubborn tarnish. Apply the paste and let it sit for 10 minutes before washing it off.

Does stainless steel change color with heat?
With the use of a blowtorch or gas burner (not included), steel and stainless parts can be colored by heating up to different temperatures: On Stainless, color changes start at approx. 550 F for a pale yellow and continue to change until a dark blue will occur at approx. 1100 F.
What happens when you overheat stainless steel?
The type of change is very dependent on the metal being overheated. A hardened steel that is subjected to overheating may have a serious loss of hardness and strength. This is because overheating changes the microstructure of steel. Overheating can cause changes to the mechanical properties of other metals as well.
What color does stainless steel turn when heated?
Steel turns blue because of a thin oxide layer that forms on the surface of the metal. The thin film interferes with light waves, which enhances some wavelengths while reducing others.
How do I remove rainbow color from metal?

Why does stainless steel discolor heated?
The surface discoloration on stainless steel after grinding or welding is surface oxidation. At elevated temperature, the metal comprising the stainless steel will combine with oxygen to form an oxide layer on the metal surface. The color of the “stain” is a function of the layer thickness.
