Cast iron is a popular choice for cookware due to its durability and heat retention properties. However, one common issue with cast iron pans is the formation of rust. Rust occurs when the iron is exposed to moisture and oxygen, resulting in a reddish, flaky substance that can affect the pan's appearance and cooking performance. While it may seem challenging to restore a rusty cast iron pan, it is possible to effectively remove rust and prevent future occurrences through proper cleaning, drying, and seasoning techniques. This process typically involves scouring the rust away, thoroughly drying the pan, and then re-seasoning it with oil to create a protective coating. With the right care and maintenance, cast iron cookware can last for generations, making it a worthwhile investment for any kitchen.

What You'll Learn
Use steel wool or a Lodge Rust Eraser to scour the rusty sections
Cast iron skillets are prone to rusting when left in humid or moist environments for extended periods. To clean rust off a cast iron pan, you can use steel wool or a Lodge Rust Eraser to scour the rusty sections.
Steel wool is a coarse scrubber that can be used to forcibly remove rust from the pan's surface. Use fine steel wool to scour the rusty sections until the area returns to raw cast iron. You can also use a scouring pad, an abrasive sponge, or fine-grit sandpaper. Apply a circular motion to scrub at the rust until it is removed.
The Lodge Rust Eraser is a product by Lodge Cookware that can be used to scour the rusty sections of your cast iron pan. This is a preferred method of cleaning cast iron, passed down through generations.
After scouring the rusty sections, wash the pan with warm, soapy water. This step may remove portions of the seasoning, but that's okay because you will be re-seasoning the pan. Dry the pan thoroughly with a paper towel or lint-free cloth. You can place it on the stovetop on low heat for a few minutes to ensure it is completely dry.
Once the pan is dry, add a thin layer of cooking oil to the entire surface of the pan. Use a cloth or lint-free paper towel to apply the oil, ensuring that there is not enough oil to drip or run when you tilt the pan.

Wash the pan with warm, soapy water
To clean rust off a cast-iron pan, you'll need to wash the pan with warm, soapy water after scrubbing it with steel wool or a stiff brush. This step removes loosened rust particles. It's important to use warm water to clean your cast iron after cooking, so the pan doesn't warp or crack from a shock of cold water.
First, fill your sink with warm water and add a mild dish soap or detergent to create a soapy solution. You can also add equal parts white vinegar and water to the mix, which will help dissolve the rust. Soak the pan in this solution for 30 minutes to an hour. Avoid soaking for longer than an hour, as the vinegar can start to eat away at the original cast surface of the pan.
Next, use a sponge, scrub brush, or non-metal brush to scrub the pan gently. You can also use mildly abrasive sponges, such as a green scrub pad or a Scotch-Brite sponge, or a scrubber made from palm fibres. If the rust is particularly stubborn, you can use fine-grit sandpaper or a metal scouring pad. However, be careful not to use harsh abrasives if your pan is made of enamel cast iron, as these can scratch or damage the surface.
After scrubbing, thoroughly rinse the pan under running water to remove any remaining vinegar, baking soda, or soap. Ensure that you remove all traces of these substances, as they can affect the taste of your food if left on the pan.
Finally, it's crucial to dry the pan immediately after rinsing. Use a clean towel to wipe the pan dry, or place it on the stove over low heat to ensure all moisture evaporates. This step is essential, as cast iron is susceptible to rust when exposed to moisture. Make sure the pan is completely dry before putting it away, and always store it in a dry, low-humidity spot.

Dry the pan thoroughly with a paper towel or on a stovetop
After scouring the rusty sections of your cast-iron pan and washing it with warm, soapy water, it's important to dry it thoroughly. Use a paper towel or a lint-free cloth to absorb any remaining water. Make sure to get the pan as dry as possible with the paper towel, and then you can place it on the stovetop on low heat for a few minutes to ensure it's completely dry. This step is crucial because any remaining moisture can cause issues when you're ready to re-season the pan.
Some people prefer to dry their cast iron on the stovetop immediately after washing, as mentioned in a comment on a Reddit thread. They recommend wiping most of the water off with a paper towel and then placing the pan on a burner on high heat for just 10 seconds to evaporate any remaining moisture. This person also emphasizes the importance of not air-drying cast iron, as it can lead to rust.
Drying your cast-iron pan thoroughly is a crucial step in the process of restoring and seasoning it. It ensures that all traces of water are removed, which is important because water can react with the iron and lead to rust. By using a combination of paper towels and stovetop heat, you can effectively eliminate any moisture and prepare the pan for the next steps in the restoration process.
The drying process is a key step in preparing the pan for re-seasoning. Seasoning is a process that coats the surface of the pan with a layer of oil, creating a non-stick, corrosion-resistant surface. By ensuring that the pan is completely dry, you create the optimal conditions for the oil to adhere properly during the re-seasoning process. A well-seasoned cast-iron pan will not only be protected from rust but will also provide a better cooking experience.
In summary, drying your cast-iron pan with a paper towel and on a stovetop is a crucial step in the process of removing rust and restoring the pan's seasoning. By eliminating all traces of water and moisture, you create the ideal conditions for re-seasoning, which helps to prevent future rust and ensures that your cast-iron pan remains a durable and effective cooking tool.

Add a thin layer of oil to the pan's surface
After removing rust from a cast-iron pan, it is important to season the pan to prevent further rusting. Seasoning is the process of coating the pan's surface with oil and baking it in the oven. This creates a corrosion-resistant coating that helps prevent food from sticking to the pan.
To season a cast-iron pan, start by drying the pan thoroughly. Any remaining water can be evaporated by placing the pan on a stove over low heat. Once the pan is completely dry, add a thin layer of cooking oil to the entire surface. Use a cloth or lint-free paper towel to apply the oil, ensuring that the layer is thin and even, with no excess oil that could drip or run.
The type of oil used can vary, but it should have a high smoke point. Examples include vegetable oil, canola oil, or grapeseed oil. Be careful not to use too much oil, as it can leave a sticky residue.
After oiling the pan, place it in the oven upside down on the center rack. This prevents oil from pooling on the cooking surface. Preheat the oven to between 350 and 500 degrees Fahrenheit, depending on the pan's instructions. Place a piece of aluminum foil on the rack below to catch any excess oil that drips.
Bake the pan for about an hour, then turn off the heat and allow the pan to cool completely inside the oven. This process bakes the oil onto the pan, creating a protective coating that helps prevent rust and makes the pan non-stick.

Bake the pan in the oven at 450-500 degrees F for an hour
After removing the rust from your cast iron pan, you'll want to dry it thoroughly. Use a clean towel or a lint-free cloth to wipe down the pan. You can also place the pan on a stovetop or burner on low heat to ensure it is completely dry.
The next step is crucial: reseasoning the pan. Apply a thin layer of vegetable oil or another cooking oil of your choice all over the pan, inside and out. This includes the bottom and handle. Be sure to use only a small amount of oil to avoid a sticky surface. Place the pan upside down in a preheated oven at 450-500 degrees F for about an hour. You can place a sheet of aluminum foil or a foil-lined baking sheet on the bottom rack to catch any oil drips.
Turn off the heat and let the pan cool in the oven. This process restores the protective layer that prevents rust and ensures a non-stick surface.
