Cleaning Rust From Carbon Steel Pan: Easy Steps To Shine

Rust on your carbon steel pan can be unsightly and it's certainly something you don't want to see when you're about to cook. But don't worry, it's a common issue and there are several ways to remove it. In this article, we'll outline the steps you need to take to get your pan looking brand new and rust-free. We'll also provide tips on how to prevent rust from forming in the first place. So, whether you're dealing with a light coating or heavy interior rust, read on to learn how to tackle it.

How to Clean Rust from a Carbon Steel Pan

The Salt Scrub Method

Don't panic if you see rust on your carbon steel pan—it's typically easy to remove and your pan will perform just as well (or even better) once it's gone. The salt scrub method is a great way to get rid of rust stains, especially if they're small to medium-sized. Here's how to do it:

• Pour some coarse salt and cooking oil (vegetable oil works well) directly onto the rust spot.
• Scrub the salt and oil into the rust using a paper towel or soft cloth. Apply a small circular motion until the rust is removed.
• Reseason the pan, unless the rust spot was minor. In this case, you can simply clean, dry, and store your pan.

This method is the least invasive way to remove rust. It's gentle on your pan and is effective on small to medium spots of rust, as well as larger areas.

The Scouring Method

Step 1: Choose the Right Scrubber

Select a scrubber that is suitable for the amount and severity of the rust. For minor to moderate rust, a scouring pad or abrasive sponge may be sufficient. For more severe or stubborn rust, you may need to use steel wool or fine-grit sandpaper.

Step 2: Prepare the Pan

If your pan has any food residue or grease, wash it with hot water and soap before beginning the scouring process. Make sure to dry the pan thoroughly after washing.

Step 3: Start Scouring

Using your chosen scrubber, apply firm pressure and work in a small circular motion directly on the rusted areas. Continue scrubbing until the rust is fully removed. You can use this method to remove rust from anywhere on the pan, including the bottom surface.

Step 4: Rinse and Dry

Once you have removed the rust, rinse the pan with hot, soapy water to remove any residue from the scouring process. After rinsing, thoroughly dry your carbon steel pan with a soft, dry cloth. Ensure that all moisture is removed to prevent new rust from forming.

Step 5: Re-season the Pan

Depending on the severity of the rust and the abrasiveness of the scrubber you used, you may need to re-season your carbon steel pan after scouring. Re-seasoning will help restore the pan's non-stick qualities and protect it from future rust.

By following these steps, you can effectively remove rust from your carbon steel pan using the scouring method. Remember to take precautions when working with abrasive materials and always work in a well-ventilated area.

The Vinegar Method

First, bring the mixture to a boil over medium heat. Then, pour it into the pan and scrub. Rinse the pan with hot water and soap. The vinegar will strip away the pan's seasoning, so it is important to re-season the pan after this process.

• Fill your sink with a 50:50 solution of water and distilled vinegar.
• Soak the carbon steel pan for one hour. If necessary, you can soak the pan for up to five hours.
• Sprinkle the pan with baking soda to neutralize the acid.
• Aggressively scrub the pan with a metal scouring pad.
• Rinse the pan with warm water until the rust is gone. If rust persists, repeat the soaking and scrubbing process.
• Dry the pan with a paper towel.
• Place the pan on a high flame for five minutes to ensure it is completely dry. Alternatively, place the pan in an oven at 350 degrees Fahrenheit for five to ten minutes.
• If small rust spots remain, wipe the pan with 100% pure flax seed oil. Do not use vegetable oil or shortening, as these can cause the carbon steel to wear down more easily.
• Re-season the pan.

Preventing Rust

Rust is the last thing any home cook or professional chef wants to see on their cookware. But fear not, there are several ways to prevent rust from forming on your carbon steel pans.

Firstly, it's important to understand why carbon steel rusts. Carbon steel contains iron, which oxidises when exposed to water for extended periods, causing rust. This is more likely to occur in humid environments or when the pan is left to air dry.

To prevent rust, always ensure your carbon steel pan is completely dry after use. You can do this by drying the pan by hand or placing it on the stove over low heat until all the water has evaporated.

Once the pan is dry, lightly coat the inside with a high smoke point oil, creating a thin protective layer. Then, remove any excess oil with a paper towel and store the pan until its next use.

If you live in a humid area or plan to use your carbon steel pan outdoors, you may need to take additional precautions. Seasoning the exterior of your pan can help decrease the amount of surface iron that could rust.

By following these simple steps, you can keep your carbon steel pans rust-free and in top condition for years to come.

Removing Rust Stains

Don't panic! Your carbon steel pan may be your pride and joy, but it is not ruined by those rust stains. It is quite normal for carbon steel to rust when left in a humid or moist environment for a long time, or if not dried properly after use. The good news is that removing rust stains from carbon steel is a simple process.

The Salt Scrub Method

This is the least invasive method for removing rust stains and is ideal for small to medium-sized spots, although it can be used for larger areas, too. Simply pour some coarse salt and cooking oil (vegetable oil is recommended) onto the rust stain and scrub with a paper towel or soft cloth in a small circular motion until the rust is removed. Then, wash, dry, and re-season the pan.

The Scouring Method

For more stubborn rust stains, a more abrasive approach is needed. Choose a scouring pad, steel wool, an abrasive sponge, or even fine-grit sandpaper to forcibly remove the rust. Using a small circular motion, scrub at the rust until it is removed. This method can be used anywhere on the pan, including the bottom. Once the rust is removed, rinse the pan with hot, soapy water, dry, and re-season.

The Vinegar Method

For really tough, interior rust stains, the vinegar method is a good option. This method will also help to prevent future rust from developing. Bring equal parts water and vinegar (rice vinegar is recommended) to a boil over medium heat. Pour the mixture into the pan and scrub. Rinse the pan with hot water and soap. Unfortunately, the vinegar will strip away any seasoning, so the pan will need to be re-seasoned.

Other Methods

There are other methods for removing rust stains from carbon steel, including using Barkeeper's Friend, a synthetic scrub pad, and a light coating of oil, or a vinegar bath.
