Cleaning Cast Iron: John Wilson's Guide

In his 2012 short film 'How to Clean a Cast Iron Pan', John Wilson offers a tutorial on how to clean cast iron cookware. The film follows a day in the life of Ahmed Khawaja and has been described as a masterclass in passive aggression. While it may not provide a clear step-by-step guide, it does offer valuable insights into other areas, such as pet ownership and cigarette etiquette. Cast iron cookware requires special care when cleaning to maintain its non-stick coating and prevent rusting. This involves hand washing, avoiding soaking, using mild detergents, and proper drying and seasoning techniques.

Use a small amount of soap and a scouring pad or brush

When cleaning a cast-iron pan, it's important to remember that a small amount of soap is acceptable to use. While some sources advise against it, others confirm that a little mild detergent or soap won't harm the pan's seasoning. So, if you're dealing with stubborn residue, a small amount of soap can be useful when combined with a scouring pad or brush.

Cast iron pans should be washed by hand. Start by using a small amount of mild dish soap and a scouring pad or brush to wash and scrub the pan. You can also use a cast-iron pan cleaning brush or a nylon scrubbing brush. If there are stuck-on food residues, a pan scraper can be useful. Avoid using metal scouring pads or scrubbers, as these can damage the pan's seasoning.

For very stubborn, stuck-on food, you can simmer a small amount of water in the pan for 3-5 minutes. After the pan has cooled, use a scraper to remove the residue. This method is also useful for removing burnt-on food. Alternatively, you can use coarse salt as an abrasive cleaner. Simply add some kosher salt to the pan and scrub with a damp sponge. The salt will clean the pan effectively without disturbing the seasoning.

Once you've scrubbed the pan with soap and removed all the residue, be sure to rinse it thoroughly. Then, dry the pan promptly and thoroughly. You can use a lint-free cloth or a paper towel for this step. If you notice any black residue on your towel, don't worry—this is normal and is just the pan's seasoning.

Don't soak the pan in water to avoid rusting

When cleaning a cast iron pan, it's important to remember not to soak the pan in water to avoid rusting. Cast iron is a porous material and can absorb water, which leads to rust formation. While it is generally fine to wash cast iron with water, it is crucial to ensure that water does not sit in the pan for an extended period.

To clean a cast iron pan effectively without soaking, start by scraping off any residue with a spatula or spoon. Then, rinse the pan with water and dry it promptly with a paper towel or a lint-free cloth. You can also place the pan on a burner for a few seconds to ensure it is completely dry. It is important to note that the pan should be thoroughly dried before putting it away, as any residual water can also cause rusting.

If there are stubborn, stuck-on food particles, avoid using metal scouring pads or steel wool as they can damage the pan's seasoning. Instead, use a nylon scrubbing brush or a pan scraper to remove the residue. For more stubborn residue, simmer a small amount of water in the pan for 3-5 minutes, then use the scraper after the pan has cooled. Remember to dry the pan thoroughly after rinsing.

In addition to drying, it is essential to apply a light layer of cooking oil or seasoning spray to the surface of the pan after cleaning. Use a paper towel to wipe the surface until no oil residue remains. This step helps maintain the pan's natural non-stick coating and prevents rusting.

By following these steps and avoiding soaking the cast iron pan in water, you can effectively clean and maintain your cookware, ensuring its longevity and performance.

Use kosher salt and a damp sponge to scrub the pan

To clean a cast iron pan, you'll need a few supplies. These include a soft sponge, coarse salt, and a bit of vegetable oil. You'll also want to ensure you have a clean dishtowel or paper towel.

Once you've gathered your supplies, follow these steps:

Step 1: Scrub with Water

Use a sponge to scrub your cast iron pan with water. Be sure to do this as soon as possible after cooking, as it will make cleaning much easier. Do not let the pan soak in water, as this can cause rusting.

Step 2: Use Kosher Salt and a Damp Sponge

If your pan still needs some extra attention, it's time to break out the kosher salt. Sprinkle a generous amount of kosher salt onto the surface of the pan. Then, take your damp sponge and scrub the salt into the pan in a circular motion. The salt acts as an abrasive cleaner, helping to remove stubborn bits of food without disturbing the pan's seasoning.

Step 3: Simmer Water (Optional)

If there are still some stubborn bits of food clinging to the pan, try this: bring a small amount of water to a boil in the skillet. Let it simmer until the water evaporates, then wipe out or scrub the pan again.

Step 4: Dry and Oil the Pan

Once you're happy with the level of cleanliness, rinse the pan well and set it on the stove over medium heat to dry. When the pan is completely dry and still warm, use a cloth or paper towel to coat it very lightly with vegetable oil. You'll need about half a teaspoon of oil for a 10-inch pan. Continue wiping the surface with oiled paper towels until the pan looks dark and smooth, and no oil residue remains.

Final Step: Let the Pan Cool

After oiling, let the pan cool completely before storing it away.

And that's it! Your cast iron pan is now clean and ready for its next use.

Use a pan scraper to remove stuck-on food

To use a pan scraper to remove stuck-on food from your cast iron pan, follow these steps:

Firstly, if there are stubborn bits clinging to the pan, try bringing a small amount of water to a boil in the skillet. Let it simmer for 3-5 minutes until the water evaporates, then wipe out or scrub the pan again. This method is also recommended by John Wilson in his tutorial on cleaning a cast iron pan.

If there is still stuck-on food, use a pan scraper to remove it. A pan scraper is a safe and effective way to remove stuck-on food without damaging the pan's seasoning. Lodge, a popular manufacturer of cast iron cookware, recommends using their Lodge Chainmail Scrubber to remove any stuck-on residue. You can also use a nylon scrubbing brush or a nonscratch pad for this purpose.

After using the pan scraper, be sure to thoroughly dry your cast iron pan with a lint-free cloth or paper towel. Cast iron is prone to rusting, so it is important to ensure that your pan is completely dry before moving on to the next step. If you notice a little black residue on your towel, don't worry – this is just seasoning and is perfectly normal.

Finally, to maintain the seasoning on your cast iron pan, rub a very light layer of cooking oil or seasoning spray onto the surface of the pan. Use a paper towel to wipe the surface until no oil residue remains. This will help to keep your cast iron pan in good condition and ensure that food doesn't stick the next time you use it.

Dry the pan with a lint-free cloth or paper towel

Drying your cast iron pan is an important step in the cleaning process. After washing your pan, it's crucial to promptly and thoroughly dry it with a lint-free cloth or paper towel. This step ensures that all moisture is removed, reducing the risk of rust formation. Cast iron is highly susceptible to rust, so taking the time to dry it properly is essential for maintaining your cookware.

When drying your cast iron pan, it's best to use a lint-free cloth or paper towel. These materials are highly absorbent and effective at removing any water residue. Avoid using cloths or towels that may leave lint or fibres behind, as these can stick to the pan's surface. By using a lint-free option, you can ensure that your pan is thoroughly dried without any unwanted residue.

As you dry the pan, you may notice a black residue on your cloth or paper towel. This residue is perfectly normal and is simply a result of the pan's seasoning. Seasoning is a natural, non-stick coating that develops on well-cared-for cast iron pans. It is created through the polymerization of oil molecules at high temperatures, resulting in a durable, smooth surface. This process enhances the pan's performance and longevity.

To ensure your cast iron pan is thoroughly dried, you can also utilize the stove. After washing your pan, place it on the stove over medium heat for a few minutes. This step will help evaporate any remaining water droplets and ensure that your pan is completely dry. This is especially useful if your pan has been soaked or exposed to excessive moisture.

Once your cast iron pan is completely dry, it's essential to proceed with seasoning. Seasoning your pan involves applying a light layer of cooking oil or spray to its surface. This step not only helps maintain the non-stick properties but also creates a protective barrier against moisture, further reducing the risk of rust. After applying the oil, use a paper towel to wipe the surface until no oil residue remains.
