There are several ways to remove rust from those carbon steel pans. Let's look at the three most popular ways to get rid of those rusty stains.
Methods cleaning carbon steel rust
Vinegar Method
If you have interior rust that is stubborn, consider the vinegar method. This method can remove existing rust and help prevent any additional build-up in the future. You need to bring equal parts of vinegar and water to a boil over medium heat. Rice vinegar often works the best for this job. Pour the mixture into the pan and then scrub. You will want to rinse with hot water and soap. Unfortunately, vinegar will strip away all of that build-up seasoning on your carbon steel, so you must re-season the pan.
Below are the simple steps you need to take to remove rust from a carbon steel skillet when using vinegar.
- Fill your sink with 50% water and 50% distilled vinegar
- Soak your carbon steel skillet for one hour. If necessary, you can soak the pan for five hours.
- After letting the skillet soak, sprinkle it with baking soda to neutralize the acid.
- Next, aggressively scrub the pan with a metal scouring pad.
- Once done, rinse the pan with warm water until the rust is gone.
- If rust is still on the pan, let it soak in the 50/50 solution for another hour and scrub it more with the metal scouring pad.
- Lastly, dry the pan with a paper towel when the rust is gone.
Now, you’re not done yet! Next, you want to place the carbon steel skillet on high flame for five minutes to completely dried the pan. Another option is to place the carbon steel skillet in the oven for five to ten minutes at 350 degrees.
If you still notice some small rust spots, it’s normal. You can wipe it with oil to help the rest of the rust come off. But don’t just use any oil. Carbon steel becomes soft, wears down, and tears more easily when lubricated with vegetable oil and shortening.
Instead, you want to use 100% pure flax seed oil. First, ensure the flax seed oil is not mixed with any other cooking oil; it has to be 100% pure.
Yes, it is a low-smoke point oil, but it’s also a drying oil. The low smoke point allows the seasoning to polymerize within the cast iron.
This molecular bonding occurs during polymerization for seasoning to adhere to the skillet. Also, the oil protects the carbon steel surface, making it smooth and hard.
Salt Scrub Method
You have to place coarse salt on the rust and use some cooking or vegetable oil. Scrub the salt and oil into the rust with a soft cloth or paper towel. Use a small circular motion to remove any traces of rust. After that, you will want to re-season the pan. However, if the rust was a minor problem, you can just clean, dry, and store the cookware.
Scouring Method
Once you have scrubbed off the rust, make sure to fully dry your carbon steel with a soft, dry cloth. If you have removed some of the seasoning, you might have to re-season the cookware.
How to season a carbon steel skillet
After you remove the rust and oil it down, you want to re-season the pan to help restore it to its former glory. Follow these steps below to season your carbon steel skillet:
- First, wipe the pan down with a paper towel.
- Then, add a tablespoon of flaxseed oil. Be sure to coat the whole pan; this includes the walls, sides, handle, and bottom.
- Now, take a fresh paper towel and rub the extra amount of oil off.
- Upside-down, place the carbon steel skillet in the oven.
- Turn the oven on at 500 degrees Fahrenheit and let the pan stay there for an hour.
- Once done, let the skillet cool off inside the oven.
It should take an hour for the pan to cool off fully; you should be able to reach in and grab the pan with your bare hands. You should repeat the process if you want good seasoning for your pan. For perfect seasoning, you can do the cycle three more times.
But why would you want to do it this many times? A good seasoning will keep your skillet in top-notch shape for years to come. Also, it’ll give the pan nonstick qualities, making cooking a breeze when you use it.

Preventing rust on carbon steel
When it comes to carbon steel, it can rust if the cookware is left in a moist environment, especially for an extended amount of time. Due to the presence of iron in the carbon steel's alloy, the oxidation process leaves rust on the cookware. Fortunately, most carbon steel cookware owners don't have to worry about rust unless exposed to water for a long time. After that exposure, you might find rust on the pot or pan.
To prevent rust from forming, take precautions with your cookware. After you use the pan, make sure to remove any traces of water from the cookware. You can accomplish this by either drying the pan by hand or putting the pan on the stove. When placing the pan in the oven, always do that over low heat. Keep it in the oven until all of the remaining water has evaporated.
Lightly coat the hot pan with cooking oil to create a very thin layer if you want to season the pan. Remove the pan from the oven and allow it to cool. After that, wipe away any excess oil and store it until you are ready to use it. With that protective oil coating, it can make a difference in preventing rust.
The above preventive steps don't always stop the development of rust on the pan, especially if it is humid or used outdoors. Under those conditions, you might need to take a few extra steps to protect it from any environmental moisture. Remember that when you season your pan, it can decrease the amount of surface iron that could rust.
Now that you know how to prevent rust on your pans, what can you do for existing rust? If you already have rust on your pans, don't worry. You can easily remove rust from your carbon steel cookware with some elbow grease.
Final word
Rust can make your pans look unsightly. In addition to that, you don't want to cook with rusty cookware. Removing carbon steel pan rust is a job that you can easily accomplish at home with a few ingredients. After a few steps, you can get your cookware looking and performing at its best.
