What You'll Learn
The Salt Scrub Method
Don't panic! Your carbon steel pan is not ruined! Minor rusting on the exterior or interior surface of your pan can happen when it is left in a humid or moist environment for an extended period of time. This is due to the presence of oxidizable iron in the alloy that forms carbon steel.
- Pour some coarse salt and cooking oil (like vegetable oil) onto the rust spot.
- Scrub the salt and oil into the rust with a paper towel or soft cloth using a small circular motion until the rust has been removed.
- Reseason the pan (unless the rust spot was minor, in which case you can clean, dry, and store the pan).
- Rinse the pan with hot soapy water.
- Fully dry your pan with a dry cloth before storing it.
If you have removed some of the seasoning, you might have to reseason the cookware.

The Scouring Method
Don't panic! Your carbon steel pan is not ruined forever. You can use the scouring method to get it looking brand new and rust-free.
Start by using a circular motion to scrub at the rust until it is fully removed. You can use these methods to remove rust from anywhere on the cookware, including the bottom of the pan.
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.
To re-season the pan, first, wipe the pan down with a paper towel. Then, add a tablespoon of flaxseed oil, coating the whole pan, including the walls, sides, handle, and bottom. Now, take a fresh paper towel and rub the extra amount of oil off. Place the carbon steel skillet upside down 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.

The Vinegar Method
Don't panic! Your carbon steel pan is not ruined. Minor rusting is normal and can be treated with a few simple steps. The vinegar method is a great way to remove heavy interior rust from your pan. Here's how to do it:
First, fill your sink with equal parts water and vinegar. Rice vinegar works best for this job. Soak your carbon steel pan in this mixture for one hour. If the rust is particularly stubborn, you can soak the pan for up to five hours. After soaking, sprinkle the pan with baking soda to neutralize the acid. This step is important to prevent flash rusting, which can occur due to the acidity of vinegar.
Next, it's time to scrub. Use a metal scouring pad and scrub the pan aggressively to remove the rust. Rinse the pan with warm water until the rust is gone. If there are still some rust spots, repeat the process by soaking the pan in the vinegar and water mixture for another hour, then scrub again.
Once the rust is removed, dry the pan with a paper towel. Place the pan on a high flame for five minutes to ensure it is completely dry. Alternatively, you can place the pan in the oven at 350 degrees Fahrenheit for five to ten minutes.
If you still notice some small rust spots, you can wipe the pan with oil to help remove the remaining rust. It is important to use the right type of oil for this step. Carbon steel becomes soft and wears down more easily when lubricated with vegetable oil or shortening. Instead, use 100% pure flax seed oil. This type of oil has a low smoke point, but it is also a drying oil, which will protect the carbon steel surface and make it smooth and hard.
Finally, you will need to re-season your pan. The vinegar will have stripped away the built-up seasoning, so it is important to re-season to restore your pan to its former glory.

Preventing Rust
- After using the pan, dry it by hand with a paper towel or a lint-free towel.
- Place the pan on the stove over low heat or in a warm oven until all remaining water has evaporated.
- Lightly coat the inside of the hot pan with a high smoke-point oil to form a thin layer. This protective coating can make a big difference in preventing rust.
- Remove the pan from the heat and allow it to cool.
- Wipe away any excess oil and store the pan until you are ready to use it again.
If you live in a humid area or plan to use your carbon steel pan outdoors, you may need to take additional precautions to protect it from environmental moisture. One way to do this is by seasoning the exterior of the pan, which will decrease the amount of surface iron that can rust.
Remember, water is the enemy of carbon steel, so always make sure your pan is completely dry before storing it away.

Re-seasoning the Pan
- Start by ensuring your pan is completely dry. Use a paper towel or a lint-free towel to wipe off any excess water.
- Place the pan on a stovetop burner or in an oven at low heat to evaporate any residual moisture.
- Lightly coat the pan with a thin layer of oil. Flaxseed oil is recommended as it is a drying oil with a low smoke point, allowing the seasoning to polymerize within the carbon steel. You can also use grapeseed oil or another neutral oil such as canola oil or vegetable oil.
- Buff the oil into the pan using a paper towel, ensuring that you remove any excess oil. The pan should look dry after buffing, as too much oil will result in a splotchy, sticky coating.
- Heat the pan on the stove at medium-high heat or in an oven at 500°F (230°C) for about 30 minutes. The pan will smoke heavily during this process, so ensure proper ventilation.
- Allow the pan to cool completely. It should change colour and darken as it cools, indicating that the seasoning has been successfully applied.
- Repeat the process if desired. A single seasoning layer will provide protection, but multiple layers will improve the non-stick properties of the pan and ensure its long-term durability.
By following these steps, you will restore your carbon steel pan to its former glory, providing a smooth, non-stick surface that is ready for your next culinary adventure.

Frequently asked questions
There are several ways to remove rust from carbon steel pans, including the salt scrub method, the scouring method, and the vinegar method. The salt scrub method is the least invasive and works well for small to medium-sized rust spots. The scouring method uses a coarse scrubber such as steel wool or an abrasive sponge to forcibly remove rust. The vinegar method is suitable for heavy interior rust and involves boiling a mixture of vinegar and water in the pan.
To prevent rust, it is important to ensure your pan is completely dry before putting it away. Wipe off excess water with a paper towel, then place the pan on a stovetop burner or in the oven to evaporate any remaining moisture. Lightly coating the pan with a high smoke point oil can also help prevent rust.
If your carbon steel pan starts to rust during cleaning, try using a paper towel with a little oil to rub the rust off. Then, season the pan.
It is recommended to use 100% pure flax seed oil or a high smoke point oil when removing rust from a carbon steel pan. Vegetable oil and shortening should be avoided as they can make the carbon steel soft and more susceptible to wear and tear.
After removing rust, it is important to re-season the pan to restore its non-stick qualities. This can be done by coating the pan with oil and placing it in the oven at a high temperature for an hour.
