Cast iron pans are robust and meant to last a lifetime, but they can be prone to rust. This is because cast iron is naturally silver in colour and will rust and turn orange/red when exposed to air and moisture. However, there is no need to panic if your cast iron pan has a little (or a lot) of rust on it. It can be restored to its original, non-stick, black patina with a few simple steps.

What You'll Learn
Use coarse salt and a potato to scrub away the rust
Cast iron pans can be restored to their original, non-stick condition even after they have rusted. While there are several methods to remove rust from cast iron, using coarse salt and a potato is a gentle, effective, and preferred method.
First, sprinkle a generous amount of coarse salt over the rusty spots on the pan. The salt acts as an abrasive, scrubbing away the rust without damaging the surface of the pan. Next, cut a potato in half and use it as a scrubber. The moisture from the potato combines with the salt to create a natural abrasive paste, helping to lift the rust from the pan. After scrubbing, rinse the pan with water to remove any salt residue. It is important to dry the pan immediately and thoroughly. You can use a clean towel or place the pan on a stove over low heat to ensure it is completely dry.
Once the pan is dry, the next step is crucial: reseasoning the pan. Apply a thin layer of vegetable oil or another neutral cooking oil with a high smoke point all over the pan, inside and out. Place the pan upside down in a preheated oven at 250°C or 500°F for about an hour. This process restores the protective coating that prevents rust and creates a non-stick surface.
While the above steps are not complicated, it is best to think of them as a backup plan. The best way to keep your cast iron in top shape is to prevent it from rusting in the first place. Along with proper cleaning and seasoning, correct storage of your pan is critical. Always ensure your skillet is completely dry before putting it away and store it in a low-humidity spot.

Soak the pan in a mixture of vinegar and water
If your cast iron pan has serious rusting, you can start by soaking it in a mixture of vinegar and water. This method can remove even the most stubborn rust, but it requires careful monitoring to avoid damaging the pan.
To begin, create a solution of equal parts water and distilled white vinegar. Ensure you have enough of this solution to completely submerge the rusty cast iron pan. Place the pan in a container, such as a bucket or deep foil pan, and pour in the vinegar and water mixture. Make sure the entire pan, including the handle, is covered by the liquid.
It is important to check the pan's progress frequently, as the vinegar effectively dissolves rust but can also start to eat away at the cast iron if left too long. Check the pan every 15 minutes to an hour, gently scratching at the rust with your fingernail or a soft brush to see if it is beginning to flake off. The pan may need to soak for up to eight hours, depending on the severity of the rust. Once the rust is easily flaking away, remove the pan from the solution.
After removing the pan from the vinegar soak, rinse it thoroughly with warm water. You can then use a scrubber or sponge to gently scrub the pan, ensuring any remaining rust is lifted. Wash the pan with a mild dish soap and warm water to remove any lingering vinegar, rust, or debris. It is crucial to dry the pan immediately and thoroughly after rinsing to prevent new rust from forming. You can use a clean towel for initial drying and then place the pan on a stove over low heat to ensure it is completely dry.
Remember, after removing rust from a cast iron pan, it is essential to re-season the pan to restore its protective coating and prevent future rust. This process involves applying a thin layer of oil to the pan, inside and out, and heating it in the oven.

Use a non-metal brush and a mixture of water and mild detergent
Cast iron cookware can rust, but it can be cleaned and restored to its original condition. Firstly, scrub the rusty sections with a non-metal brush and a mixture of water and mild detergent. You can use a non-metal brush, such as a stiff-bristled brush or a sponge, to scrub the rusty areas. For more serious cases of rust, you can use fine-grit sandpaper or a metal scouring pad.
After scrubbing, wash the pan with warm, soapy water to remove any loose rust and debris. Rinse the pan thoroughly to ensure that all the detergent is removed. It is important to dry the pan completely after washing to prevent more rust from forming. You can use a lint-free cloth or paper towel to dry the pan, or you can place it on a stove over low heat to ensure it is thoroughly dry.
Once the pan is dry, the next step is to reseason the pan. This involves coating the pan with a thin layer of cooking oil, such as vegetable oil, to restore the protective layer that creates a non-stick surface. Preheat the oven to between 450 and 500 degrees Fahrenheit. Apply a thin layer of oil all over the pan, inside and out, using a cloth or lint-free paper towel. Place the pan upside down in the oven for about an hour. This process will create a protective coating that prevents rust and a non-stick surface.

Create a paste with water and baking soda
Cast iron cookware can rust, but it can be cleaned and restored to its original condition. Removing rust from cast iron pans can seem daunting, but it can be done with common household items. Firstly, scrub the rusty areas with steel wool or a stiff brush to remove surface rust. Then, wash the pan with warm, soapy water to remove any loose rust and debris. Rinse thoroughly afterward.
For stubborn rust spots, create a paste of equal parts water and baking soda. Apply this paste directly to the rusty areas and let it sit for a few minutes. Then, using a scrubbing pad or brush, gently scrub the paste into the rusted spots. You will notice the rust starting to lift away from the pan.
After scrubbing, rinse the pan thoroughly with warm water to remove any remaining paste and loosened rust particles. It is important to dry the pan completely after rinsing to prevent new rust from forming. You can do this with a clean towel or by placing the pan on a stove over low heat to ensure all moisture is evaporated.
The next step is crucial: reseasoning the pan. Apply a thin layer of vegetable oil or another high smoke point oil all over the pan, inside and out. Place the pan upside down in a preheated oven at 250°C to 450°C for about an hour. This process replenishes the protective coating that prevents rust and creates a non-stick surface.

Wash with warm, soapy water and dry thoroughly
To remove rust from a cast iron pan, a paste made of water and baking soda can be used, or a mixture of vinegar and salt. After this, the pan should be washed with warm, soapy water and dried thoroughly. This step is important, as it ensures that the pan is free of any residue and helps to prevent future rusting. Here's a detailed guide to achieving this:
Start by filling your sink with warm water and adding a few drops of mild dish soap. Avoid using harsh, abrasive cleaners, as these can damage the seasoning on your pan. Submerge the pan in the soapy water and use a soft-bristled brush or non-abrasive sponge to gently scrub away any remaining rust or debris. Ensure you scrub all surfaces, including the handle and exterior sides of the pan.
Rinse the pan thoroughly with warm water to remove any soap residue. Pay extra attention to the corners and edges of the pan, where soap or debris may accumulate. After rinsing, use a clean, dry towel to thoroughly dry the pan. Be sure to dry both the interior and exterior surfaces, as well as the handle. Leaving the pan even slightly damp can lead to the formation of new rust, undoing your efforts.
If your pan has stubborn rust spots that persist after the initial cleaning, you can repeat the process. Alternatively, you can make a paste with baking soda and water, applying it to the affected areas and letting it sit for a few minutes before scrubbing gently with a soft brush or sponge and rinsing it clean. You could also use a mild acid like vinegar or lemon juice for this step, but be cautious as these can affect the seasoning of your pan if used in excess.
Once you're satisfied that all the rust has been removed and the pan is thoroughly dried, it's a good idea to apply a thin coat of vegetable oil or shortening to the surface. Use a paper towel or clean cloth to rub a small amount of oil onto the pan, ensuring an even coating. This will help to restore the seasoning of the pan, creating a non-stick surface and adding a layer of protection against future rusting.
