Cleaning Cast Iron: Simple Steps For Sparkling Pans

Cast iron pans are a must-have for any home cook, but keeping them clean can be a challenge. The internet is full of conflicting advice on how to care for these durable pans, with some advocating for soap and others warning against it. So, what's the best way to clean a cast iron pan? Here's a simple guide to ensuring your cast iron stays in top condition. Firstly, always clean your cast iron pan by hand with hot water as soon as possible after use. Stuck-on food can be a challenge, but it can be loosened with hot water, a stiff brush, and some elbow grease. For extra tough messes, a paste of coarse salt and water can work wonders. It's important to dry your pan thoroughly after washing to prevent rust, and then a light coating of vegetable oil will help to protect the surface. While some sources advise against using soap, others say a small amount of mild soap is fine, as long as you re-season the pan afterwards. So, while cast iron pans may require a little extra care, they're well worth the effort.

How to clean a cast iron pan without soap

Cast iron pans are a great addition to your kitchen, and with the right care, they can last a lifetime. Here is a step-by-step guide on how to clean your cast iron pan without using any soap.

Firstly, it is important to note that you should never soak your cast iron pan in water as this can cause rusting. If you have burnt-on food residue, the best way to remove it is by using hot water and a wooden spatula or a scrubbing brush. You can also use a pan scraper to remove stuck-on food. For stubborn residue, you can simmer a little water in the pan for 3-5 minutes and then use the scraper after the pan has cooled.

Once you have removed the food residue, rinse the pan with water and dry it thoroughly. You can place the pan on the stove over medium heat for a few minutes to ensure complete drying. It is crucial to get your pan bone dry before the next step.

The next step is to season the pan. Take a paper towel or a clean cloth and rub a very light layer of cooking oil, such as vegetable oil or canola oil, onto the surface of the pan. Make sure to wipe the surface until no oil residue remains. Alternatively, you can use a seasoning spray for this step.

If your cast iron pan has developed some rust, don't panic. You can remove the rust by using the rough side of a dry scrubbing pad or a Scotch-Brite sponge. Rinse the pan, dry it thoroughly, and then re-season it with oil.

By following these steps, you can effectively clean and maintain your cast iron pan without using any soap. With proper care, your cast iron pan will develop a natural, non-stick finish and last for generations.

How to dry a cast iron pan

Drying a cast-iron pan is a crucial step in the cleaning process, as any remaining water droplets can cause rusting. Here is a detailed guide on how to dry your cast-iron pan effectively:

• After rinsing your cast-iron pan, use a clean, lint-free cloth or paper towel to wipe it down promptly and thoroughly. It is normal to see some black residue on your towel, as this is just seasoning.
• To ensure your pan is completely dry, place it on the stove and turn the burner to high. Allow the pan to heat up and evaporate any remaining water. This step is essential to prevent rusting.
• Once the water has boiled off, turn off the heat. You can then apply a light layer of cooking oil or seasoning spray to the surface of the pan. Use a paper towel to wipe the surface, removing any excess oil residue.
• Some people prefer to heat their cast-iron pans after oiling. This step is optional but can help burn off any remaining water droplets and enhance the seasoning. Simply heat the pan on the stove or in the oven at a high temperature for a few minutes.
• If you accidentally leave your cast-iron pan in water for too long and it develops rust, don't panic. You can remove the rust by scrubbing it with steel wool and warm, soapy water. Rinse and dry the pan thoroughly before applying a thin layer of cooking oil.

Remember, always avoid soaking your cast-iron pan in water, as it can lead to rusting. Instead, focus on prompt and thorough drying, followed by oiling, to maintain the condition of your cast-iron cookware.

How to season a cast iron pan

Seasoning a cast iron pan is a straightforward process that will ensure your cookware is protected and has a natural, easy-release finish.

Firstly, wash and dry your pan. Give it a good scrub with warm, soapy water, then dry it thoroughly. You can use a stove-top flame for a couple of minutes to ensure all the water has evaporated.

Next, rub the pan all over with cooking oil. This includes the handle and the bottom of the pan. Use a neutral oil like canola, vegetable, grapeseed, or flaxseed oil. You want a thin film of oil with no pooling; the pan should feel almost dry to the touch.

Then, place the pan upside down in an oven preheated to between 350-500°F. Place a baking sheet or aluminium foil on the rack below to catch any oil drips. Leave the pan for around an hour. You can then turn off the oven and let the pan cool inside.

Repeat these steps multiple times for an unseasoned or stripped pan. You can also season a cast iron pan on a stove-top burner, but this may create hot and cool spots, leading to uneven seasoning.

How to remove rust from a cast iron pan

Cast iron cookware is made to last a lifetime, so even a rusty pan can be restored to its former glory. Here's how to remove rust from a cast iron pan:

Step 1: Remove the Rust

Use fine steel wool, a scouring pad, or a Lodge Rust Eraser to scour the rusty sections of the pan until the area returns to raw cast iron. If you have a lot of rust to remove, you can also try soaking the pan in a mixture of equal parts water and distilled white vinegar. Check the pan every 15 minutes and remove it from the solution once the rust easily flakes away.

Step 2: Wash the Pan

Wash the pan with warm water and a mild dish soap. You can use a scrubbing brush, scouring pad, sponge, or towel to scrub the pan. This step will remove any remaining rust and prepare the pan for reseasoning.

Step 3: Dry the Pan

Thoroughly dry the pan with a lint-free cloth or paper towel. You can also place the pan on the stovetop on low heat for a few minutes to ensure it is completely dry.

Step 4: Reseason the Pan

Add a thin layer of cooking oil to the entire surface of the pan, including the bottom and handle. Then, place the pan upside down on the top rack of your oven and place a sheet of aluminum foil or a foil-lined baking sheet on the bottom rack to catch any oil drips. Preheat the oven to between 350-500°F and heat the pan for one hour. Turn off the heat and let the pan cool in the oven.

Your cast iron pan should now be rust-free and ready to use! To prevent rust from returning, always ensure your pan is completely dry before putting it away and store it in a low-humidity spot.

How to store a cast iron pan

Knowing how to store cast iron is just as important as knowing how to cook with it. Improper storage can lead to early rust buildup, reducing the lifespan of your cast iron cookware.

Before Storing:

First, ensure that all food particles are cleaned from the cast iron cookware. Rinse your skillet after every use, and dry it thoroughly with a lint-free cloth or paper towel. You can also place the pan on the stove and heat it gently until all the water evaporates. Then, rub a thin layer of cooking oil or seasoning spray onto the pan's surface. Use a paper towel to wipe the surface until no oil residue remains.

Where to Store:

• Dry cabinet: A typical kitchen cabinet is a good storage space for cast iron, as long as it's dry. Excess moisture can quickly turn into rust on highly reactive cast iron.
• Stovetop: You can keep your cast iron out on the countertop or stovetop, as long as it's moisture-free and far removed from the kitchen sink area.
• Oven: The oven is a great storage space for cast iron, as it's a low-moisture environment with plenty of space. Just remember to remove the pan before heating the oven.
• Hanging: You can hang your cast iron on the wall, either mounted on the wall or ceiling. This makes the pans decorative and functional, but ensure that the hooks are securely mounted to studs, as cast iron is heavy.
• Paper towels: No matter where you store your cast iron, place paper towels between the pans to prevent scratching and rusting.
