Cast iron pans are known for their durability and versatility, but they do require special care when it comes to cleaning and maintenance. Proper cleaning techniques are essential to preserve the pan's seasoning, a natural non-stick coating that develops over time, and to prevent rusting. While some sources advise against using soap, as it can strip the seasoning, others suggest that a small amount of mild dish soap is acceptable and will not cause significant harm. To clean a cast iron pan, it is recommended to start by cleaning it while it is still hot, using hot water and a cast iron scrubber or chainmail scrubber to remove any stuck-on food residue. For stubborn messes, coarse salt and a dry towel can be used for extra abrasion. After cleaning, the pan should be thoroughly dried on the stove to ensure all water has evaporated, and then seasoned with a thin layer of oil to maintain its non-stick properties. With proper care, cast iron pans can last for generations.

Using soap
It is safe to use soap when washing a cast iron pan, as long as it is a modern dish soap and not a traditional soap made with lye, which would strip the seasoning and damage the pan. You should also avoid using large amounts of soap as this can strip the pan's seasoning. It is recommended to use a mild dish soap with hot water and a non-abrasive sponge, nylon brush, or scrub brush.
If there is stuck-on food, it is recommended to first simmer a small amount of water for 3-5 minutes to loosen the food and then use a wooden spatula or pan scraper to remove it. You can also use steel wool to scrub off stuck-on food, but this will remove the seasoning, so the pan will need to be re-seasoned.
After washing with soap, the pan should be dried promptly and thoroughly with a lint-free cloth or paper towel. It is important to ensure that the pan is completely dry to prevent rust. The pan can be dried on the stove over medium heat for 3-5 minutes and then allowed to cool completely.
Once the pan is dry, a light layer of cooking oil, such as flaxseed, canola, or vegetable oil, should be rubbed on the surface. Any excess oil should be wiped out, leaving only a thin layer. This helps to maintain the seasoning of the pan.

Removing rust
Cast iron pans are sturdy and long-lasting, but they do require some care when cleaning to maintain their non-stick coating and prevent rusting. Here are some detailed, step-by-step instructions for removing rust from your cast iron pan:
- Start by scrubbing the rusty sections of the pan vigorously. You can use steel wool, a Lodge Rust Eraser, or a ball of tin foil dipped in vinegar. Get the pan back to its original cast iron surface, ensuring all the rust is gone.
- Wash the pan with warm, soapy water. This step may remove some of the seasoning, but that's okay, as you will be re-seasoning the pan.
- Rinse the pan thoroughly and hand-dry it completely with a paper towel or lint-free cloth. You can also place the pan on the stovetop on low heat for a few minutes to ensure it is bone dry.
- Apply a thin layer of cooking oil to the entire surface of the pan, inside and out. Be careful not to use too much oil, as this can make the pan sticky.
- Place the oiled pan upside down on the top rack of the oven. Put a baking sheet or aluminium foil on the bottom rack to catch any oil drips.
- Preheat the oven to between 450-500 degrees Fahrenheit and bake the pan for about an hour.
- Allow the pan to cool, and repeat the process if necessary, until the pan achieves a classic black patina.
Now that your pan is free of rust, be sure to dry it thoroughly after each wash and apply a thin layer of oil to prevent rust from returning.

Scraping vs. soaking
Cast iron pans are known for their durability and longevity. However, they do require special care when cleaning to maintain their non-stick coating and prevent rusting. While cast iron pans are robust, they should be treated with care to avoid damaging the seasoning.
Scraping is a popular method for cleaning cast iron pans. It is an effective way to quickly remove stuck-on food residue without damaging the pan. It is important to note that metal scrapers should only be used on untreated cast iron pans without any coating. For coated pans, it is recommended to use scrapers made from alternative materials, such as polycarbonate or hardwood. When using a metal scraper, it is crucial to apply the right amount of force to loosen the residue without gouging the metal. Starting the process while the pan is still hot can make it easier. If the pan has cooled, adding a little water and heating it on the stove can also help soften the residue.
Soaking is another method that is commonly associated with cleaning cast iron pans. However, this practice is generally not recommended. Due to the porous nature of cast iron, soaking can lead to rusting over time. While it may seem like a gentle way to loosen stuck-on food, it can be ineffective, and the food may still need to be scraped off afterward.
When faced with the decision between scraping and soaking, scraping is generally the preferred method for cleaning cast iron pans. It is important to use the appropriate type of scraper for the specific pan and to apply the right amount of force to avoid damaging the seasoning or the pan itself. While soaking may seem like a convenient option, it can lead to rusting issues and may not effectively remove all the residue. Therefore, scraping is a more efficient and safer choice for maintaining the condition of cast iron pans.

Re-seasoning
Cast iron pans require a little extra care when it comes to cleaning and maintaining them. This is because they are seasoned, which gives them a natural non-stick coating. This seasoning can be stripped, for example by using too much soap, or by soaking the pan in water, which can also cause rusting.
If your cast iron pan has lost its seasoning, you can re-season it by following these steps:
- Clean the pan with warm water. You can use a small amount of soap, but avoid using too much as this can strip the seasoning. Use a nylon scrub brush or a pan scraper to remove any stuck-on food. If your pan has rusted, use steel wool or fine steel wool to remove the rust.
- Dry the pan thoroughly inside and out.
- Coat the pan with a thin layer of cooking oil, such as grapeseed oil, avocado oil, or canola oil, or vegetable oil. You can use a paper towel to rub the oil onto the pan, making sure to cover the inside, outside, and handle.
- Place the pan upside down on the middle rack of an oven preheated to 350-500˚F. Place a sheet of aluminum foil on the lower rack to catch any drips.
- Bake the pan for 30 minutes to 1 hour. You will see some smoke coming from the pan as the oil begins to polymerize. Once the smoke stops, the polymerization process is complete.
- Turn off the oven and leave the pan inside to cool slowly.
- Repeat the process of coating the pan with oil and baking it if desired. This will add another layer of seasoning to your pan.
- Once the pan is cool, wipe away any excess oil with a paper towel.
Your cast iron pan is now re-seasoned and ready to use! Remember to wash it with hot water (no soap) and dry it thoroughly after each use. You can also rub a little oil onto the pan after each cleaning to protect the surface.

Drying and storing
It is important to ensure that your cast iron pan is completely dry before storing it to prevent rust. If you are not using the pan for a while, it is a good idea to place a couple of paper towels inside the pan to absorb any moisture that may form while it is stored. Store your cast iron pan with the lid off, especially in humid weather. When cast iron is covered, moisture can build up and cause rust.
You can also lightly oil the inside of the pan using a paper towel before storing it. Use any food-grade oil, and rub it well to create a sheen but not a greasy layer. If you use too much oil, it may become rancid.
Cast iron pans should be stored in a dry, well-ventilated area. Avoid storing them in plastic bags or containers, as this can trap moisture and cause rust. It is also not recommended to store cast iron pans in the oven, as they can be accidentally left on during the self-cleaning cycle, which can strip the seasoning.
Overall, proper drying and storing of your cast iron pan are crucial to maintaining its seasoning and preventing rust. By following these steps, your pan will be ready for your next culinary adventure!
