A stainless steel pan is a great kitchen tool for so many favorite dishes. From searing the perfect steak to simmering a spaghetti sauce, stainless steel pans represent a superior choice.
However, these indispensable kitchen tools are not without head-scratching issues.
Read on to learn how to prevent and fix the most common problem with stainless steel pans: discoloration.
While not dangerous to your kitchenware or those eating your food, discoloration on stainless steel pans is unpleasant.
Like many of our prized pans, stainless steel perfection doesn’t last.
A few different cooking situations can cause stainless steel pan discoloration. Many of these are from the natural side effects of cooking.
If your water has high levels of calcium, white deposits may remain in your stainless steel pans. This residue is stubborn to remove, but not impossible.
Like many of the types of discoloration on this list, calcium build-up is not harmful.
These white deposits on your cookware are unsightly. However, the residue will not affect the food.
It is common for food residue to collect in a stainless steel pan. In fact, even more so than other cookware materials like non-stick or surfaces coated with enamel.
The proper amount of oil is crucial when using a stainless steel pan. Knowing a few basics on how to cook with stainless steel is important to prevent black, sticky build-up.
While food residue may not be directly harmful, it should be removed. Leaving residue behind will affect the flavor of future meals you prepare in your stainless steel pan.
Pitting in your stainless steel pans is the corrosion of the surface.
Pitting is often caused by boiling salted water in your stainless steel cookware. Pits appear as small, black circles.
These pits are irreversible and will gradually eat through the pans. Pitting is frequently the precursor to rust. Pitting is one of the more harmful discolorations possible in stainless steel.
The rainbow-colored, oil slick-esque drips and rings can easily appear in the shallow bottom of your pan.
These look wrong and scary, but it is a totally normal and preventable phenomenon.
The answer to stainless steel pan discoloration is simple: science! Normal chemical reactions occur when oxygen, heat, and chromium, a common ingredient in stainless steel, combine.
Chefs call this rainbow film “heat tint.” It is completely natural for your stainless steel pan’s chromium layer to thicken. This produces the rainbow film, which chefs call a “heat tint”.
Chromium is used precisely because it prevents rust or corrosion. This strong metal substance shows off this power through the appearance of this mysterious, colorful film in your pans.
Chromium could be omitted from the stainless steel recipe. But then the harmless stains collecting in your pan would become rust. In a way, this film is a bit of a kitchen hero!
This discoloration is a natural scientific process and cooks should not fret about these rainbow visitors in your pans. Heat tint does not affect the food’s flavor or the pan’s performance.
Stainless steel cookware is a wise choice for many recipes. This resilient, heavy-duty material will last for many years.
However, stainless steel and chromium are not without special quirks.
Stainless steel pan discoloration is a normal side effect of cooking. Every time you fire up that skillet for a perfect salmon sear, the heat tint isn’t far behind.
However, there are ways you can prevent stainless steel pan discoloration.
These tips will assist you both before and after purchasing your next stainless steel pan.
As discussed above, oxidation of chromium, stainless steel cookware’s essential ingredient, causes discoloration.
Oxidation only occurs when high heat is introduced to the situation.
To prevent heat tint, grab stainless steel pans for low-heat cooking.
Simmering a big sauce in a large skillet on the stove is an example. This application assists with maintaining gleaming pans.
However, stainless steel pans beautifully conduct and hold heat. This makes them a wonderful choice for searing, even though it requires high heat.
In the next section, we will address fixing heat tints and other discolorations. So don’t feel like you can never use stainless steel pans in high-temperature cooking situations.
Another suspect in those rainbow stains on your stainless steel pans is harsh chemicals. Cleansing agents with chlorine or bleach can cause these stains or harmful pitting.
We also do not recommend placing this cookware in the dishwasher.
The combination of very high heat and strong chemicals in dishwashing detergent is terrible for stainless steel pans.
Inexpensive stainless steel pans are alluring, but the lower price comes at a price.
Manufacturers reduce the cost of cookware by producing thin cookware with less chromium.
As we mentioned above, chromium is the essential ingredient in stainless steel pans.
Chromium contributes to the long-term resiliency of the pans. This substance mainly reduces rust damage.
Cheaper stainless steel pans discolor more quickly and can even rust. By investing in a higher quality pan, you take an important step in maintaining the gleaming finish on your cookware.
A common reason for pitting in stainless steel is salt. Boiling salted water in a stainless steel pot for pasta takes several minutes.
Using a pan regularly in this way can wear the surface away.
Instead of adding the salt to cold water and then boiling it, bring water to a boil first.
After the boil, then add salt.
This reduces the amount of time corrosive salt is in contact with the cookware.
Sometimes you have passed the point of prevention with your stainless steel. No problem! Many of the causes of stainless steel pan discoloration is normal cooking techniques.
Before we describe how to fix each of the discolorations described, there are a few basic guidelines. Stainless steel has a few important rules to avoid irreversible damage.
First, never use steel wool or a wire brush for cleaning stainless steel. These materials are much too abrasive.
Harsh chemicals like chlorine or bleach are also too severe for stainless.
Review how to identify the grain of stainless steel before cleaning. Avoid going against the grain of the cookware.
If you go against the grain, you won’t achieve the desired gleaming surface.
Whenever you clean a stainless steel pan, be sure to dry it completely after you are finished. If you don’t, calcium residue or heat tint can simply appear again right away.
Prepare a vinegar solution with one part vinegar to three parts water. Spray this solution on the area of the stainless steel pan with the heat tint.
Let this sit for a few minutes and rinse away.
Mix vinegar and water in equal amounts and apply to the white residue.
If the build-up is severe, let the cookware sit in the solution for ten minutes. Rinse the pan and dry completely.
Is your stainless steel pan’s bottom no longer silver, but now kind of dark brown?
This residue is the result of excess oil fusing into the cookware, especially cooking oils in aerosol sprays.
Remove this sticky surface by soaking the cookware in warm, soapy water. Then transfer the pan to the stovetop, brimming with the soap water. Bring this soap water solution to a boil.
After the water heats up, use a silicone spatula to scrape away at the residue. Be careful not to use a metal or rubber spatula for this task. Empty the pan and repeat the process as needed.

Restore the Shine
Make your stainless steel cookware look new again!
Sprinkle baking soda on the stainless steel surface and spray over it lightly with vinegar. Combine the mixture together with a cloth.
Next, drizzle a few drops of dishwashing soap over the surface.
Rub this into the other solution lightly, making small circles. Leave this solution on the surface for one hour before rinsing.
There are a few discolorations on this list that require cooks to purchase new cookware.
If the pan’s discoloration affects the performance of the pan or the food’s flavor, it is time to replace it.
If you experience pitting or any rust, we recommend buying a replacement pan. This discoloration is irreversible. Also, pitting and rust will eventually eat away the cookware entirely.
However, some of the discolorations mentioned are harmless and easily remedied. If you have a sticky, brown residue on the bottom of the pan or fused food, that is a quick fix!
