The Dirty Truth: Why You Should Leave Your Cast Iron Pan Alone

Leaving your cast iron pan dirty is not recommended. While cast iron is tough and difficult to ruin, it does require some care to keep it in good condition. Food residue left in the pan can rot, and exposing the pan to moisture for extended periods can cause rust. To clean your cast iron pan, wash it by hand with a small amount of soap and hot water, using a pan scraper or nylon brush for stuck-on food. Dry it thoroughly and then rub a light layer of cooking oil on the surface.

How to clean a cast iron pan without re-seasoning it

Cast iron pans are durable and long-lasting, but they do require some care and attention when it comes to cleaning. Here's a step-by-step guide to cleaning your cast iron pan without re-seasoning it:

Step 1: Scrub the Pan

After cooking, use a soft sponge or a non-abrasive scrub brush to gently scrub your cast iron pan. You can use mild dish soap and hot water to clean the pan. Avoid using steel wool or metal scrubbers, as they can damage the pan's surface.

Step 2: Rinse and Dry

Rinse the pan with clean water to remove any soap residue. Dry the pan thoroughly with a clean dish towel or paper towel. It's important to ensure that the pan is completely dry before moving on to the next step.

Step 3: Remove Stuck-on Food (If Necessary)

If there are any stuck-on bits of food, you can use one of the following methods:

• Kosher Salt: Sprinkle kosher salt on the affected area and scrub gently with a damp sponge. The salt acts as an abrasive cleaner without damaging the pan's seasoning.
• Boiling Water: Add a small amount of water to the pan and bring it to a boil. Let it simmer for a few minutes, then use a wooden spatula to scrape off any remaining food bits.
• Simmering Water: Simmer a small amount of water in the pan for 3-5 minutes. Let the pan cool, then use a pan scraper to remove stuck-on food.

Step 4: Re-Oil the Pan

Once the pan is clean and dry, apply a thin layer of cooking oil, such as canola or vegetable oil, to the surface. Use a paper towel to wipe the oil evenly across the pan's surface, including the handle. This step helps maintain the pan's seasoning and prevents rust.

Step 5: Store the Pan

After oiling, let the pan cool completely before storing it away. Make sure to store the pan in a dry place to prevent rusting.

Tips:

• Do not soak your cast iron pan in water, as it can promote rusting and damage the seasoning.
• Avoid using steel wool or metal scrubbers, as they can remove the seasoning and damage the pan's surface.
• If you need to remove stubborn rust, you can use a mild acid like vinegar or a specialised rust remover like Bar Keepers Friend.
• While mild dish soap is generally safe to use, avoid using large amounts, as it can strip the seasoning over time.

What to do if your cast iron pan has developed rust

Cast iron cookware is susceptible to rust when left unseasoned, soaked in water, put in the dishwasher, air-dried, or stored in a moisture-prone environment. If your cast iron pan has developed rust, there are several methods you can use to remove it:

Scouring and Washing: Start by scouring the rusty sections with steel wool or a Lodge Rust Eraser. Then, wash the pan with warm, soapy water. This step may remove portions of the seasoning, but that's okay, as you will be re-seasoning the pan afterward.

Drying: Completely dry your cast iron pan 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.

Oil Application: Add a very thin layer of cooking oil to the entire surface of your cast iron with a cloth or lint-free paper towel. Be careful not to use too much oil, as you only want a thin layer that won't drip or run when you tilt the pan. Thin layers are important for baking seasoning into the pan.

Oven Seasoning: Preheat your oven to 450–500 degrees Fahrenheit. Place aluminum foil on the bottom rack of the oven to catch any excess oil. Place your cookware upside down on the center rack to prevent oil from pooling on the cooking surface. Bake for 1 hour, then turn off the heat and allow the cast iron to cool in the oven. This allows the seasoning to cure and adhere to the iron.

If the rust is only in a few spots, you may not need to go through the oven seasoning process. Instead, simply scrub away the rust with an abrasive tool under cold water, dry the skillet, and wipe it down with a paper towel or rag oiled with seasoning oil. Repeat these steps until the rust is no longer visible.

Once you've removed the rust, it's important to take steps to prevent it from happening again. Always dry your cast iron pan thoroughly after use and store it in a dry area. Additionally, regularly oil your pan lightly to protect it from rusting.

How to remove lingering smells from a cast iron pan

Cast iron pans can absorb strong odours due to their porous nature, but there are several ways to remove these smells.

Firstly, it is important to clean the pan as soon as it is cool enough to handle. For a light dish with minimal oil, simply wiping the pan with a clean, dry paper towel should be sufficient. For greasier dishes or where there is significant food residue, wash the pan with mild dish soap and a non-abrasive scrub brush or sponge.

If your pan has a lingering smell, there are several methods you can try to remove it:

• Wash the pan with mild dish soap and dry it well with a towel. Then, heat it in the oven at 400°F for 15 minutes.
• Sprinkle a layer of regular table salt over the dry pan's cooking surface and leave it overnight. In the morning, pour out the salt, rinse and dry the pan.
• Heat the pan on the stovetop for about 15 minutes. Some people recommend applying a thin layer of oil to the pan before heating, but this is not necessary and can create more work as you will need to wipe off the excess oil afterwards.
• Reseason the pan. Start by scouring the surface with warm, soapy water and a metal scouring pad. Rinse and dry thoroughly. Apply a thin, even layer of cooking oil to the pan and place it upside down on the top rack of the oven. Place a sheet of aluminium foil on the bottom rack to catch any excess oil. Bake at 450-500°F for one hour. Allow to cool and repeat as necessary.

It is important to note that you should avoid using harsh chemicals or abrasives that could damage the pan's seasoning. Additionally, avoid boiling vinegar or lemon juice in the pan, as the acidity can strip away the seasoning.

How to prevent your cast iron pan from getting rusty

Cast iron pans are susceptible to rust without a protective layer of carbonized oil, also known as seasoning. Even a well-seasoned pan can rust if it's exposed to moisture, so it's important to take steps to prevent this from happening. Here are some ways to prevent your cast iron pan from getting rusty:

Cleaning and Drying:

Always clean your cast iron pan promptly after use. While it's generally advised against soaking cast iron pans, if there is stuck-on food, you can fill your pan with a small amount of water and simmer it for 3-5 minutes before using a pan scraper to remove the residue. Avoid using steel wool or metal scrubbers, as these can damage the seasoning. Instead, opt for nylon scrubbing brushes or pan scrapers. Thoroughly dry your pan with a lint-free cloth or paper towel, ensuring that all water residue is removed. You can also place the pan on the stovetop over low heat to ensure complete evaporation of any remaining moisture.

Re-seasoning:

After cleaning and drying, it's important to re-season your cast iron pan to restore the protective layer. This involves coating the pan with a thin layer of cooking oil, such as vegetable oil, and rubbing it over the entire surface, including the handles, outside, and bottom if they aren't enamel-coated. You can then place the pan in the oven, upside down, at a temperature between 450-500 degrees Fahrenheit for about an hour. This process bakes the oil into the pan, creating a non-stick surface and a signature dark matte finish.

Proper Storage:

Always ensure your cast iron pan is completely dry before storing it. Choose a dry, low-humidity storage area, as storing your pan in a moisture-prone environment can lead to rust. If you're stacking multiple cast-iron pans, use pan separators or layers of paper towels between them to prevent moisture buildup.

By following these simple steps of cleaning, drying, re-seasoning, and proper storage, you can effectively prevent your cast iron pan from getting rusty and enjoy its durability for years to come.

How to clean a cast iron pan with a potato and salt

You should never leave your cast iron pan dirty, as food residue will rot in the pan between uses. It is important to clean and dry your cast iron pan thoroughly after each use to prevent rust.

Step 1: Rinse out your pan with water, then dry the pan with a paper towel to remove any large gunk or food residue.

Step 2: Pour a generous amount of coarse salt into the pan (about 1/4 to 1/2 cup, depending on how dirty or rusty the pan is). Coarse salt is preferred, but regular table salt will also work.

Step 3: Cut a Russet (baking) potato in half. The potato contains natural oxalic acid, which is often found in household cleaning products and acts as a dissolving agent to clean rust.

Step 4: Place the potato, cut side down, into the pan, on top of the salt. Use the potato to scrub the pan in a circular motion. You can also scrub in a back-and-forth motion for more stubborn residue.

Step 5: Keep scrubbing with a good amount of pressure. You will see the dirt start to come off and mix with the salt. The moisture from the potato will help "activate" the salt, allowing it to better remove rust and dirt.

Step 6: Scrub the entire pan until it is clean. If your pan has an uncoated cast iron handle, edges, or bottom, be sure to scrub those parts as well. If your salt gets very dirty, rinse the pan with water, pat it dry, and start over with a new batch of salt.

Step 7: Once the pan is completely clean, rinse it with water and pat it dry with a paper towel.

Step 8: Place the pan on the stove over low heat for a few minutes to ensure any remaining moisture is evaporated.

Note: This cleaning method can be a bit messy, so it is recommended to do it outside, in the sink, or with a newspaper underneath to catch any flying salt. Additionally, if your pan has a lot of stuck-on food residue, you can try the boiling water method before scrubbing with the potato and salt. Simply add 1 to 2 cups of water to the pan, bring it to a boil, and use a wooden spatula to scrape off the loosened food bits.
