Reviving Rusty Cast Iron: A Step-By-Step Guide To Restoring Old Pans

Cast iron pans are durable and versatile, but they require a little TLC when it comes to cleaning and maintenance. Here's a step-by-step guide on how to wash an old cast iron pan:

- Clean the pan while it's still hot. Don't let it sit for too long as stuck-on food will harden as it cools.

- Wash the pan with hot water and a mild dish soap. You can use a small amount of soap, contrary to popular belief. Avoid using metal scouring pads or putting the pan in the dishwasher.

- For stuck-on food, use a pan scraper, a wooden or plastic utensil, or a non-scratch scrubber sponge. You can also try adding some kosher salt and scrubbing with a damp sponge. The salt acts as an abrasive cleaner without damaging the seasoning.

- If food is still stuck on, simmer a small amount of water in the pan for a few minutes, then use the scraper after it has cooled.

- Dry the pan promptly and thoroughly with a lint-free cloth or paper towel. Make sure to get it bone dry before storing to prevent rust.

- To ensure the pan is completely dry, place it on the stove over low heat or in the oven at a low temperature until all the moisture evaporates.

- Once dry, rub a 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.

- Let the pan cool completely before storing.

Use a small amount of soap

Contrary to popular belief, you can use a small amount of soap to wash your cast iron pan. However, it is important to note that large amounts of soap can strip the seasoning off your pan. Therefore, it is recommended to use a mild dish soap and avoid power cleansers or aerosol oven cleaners, as these can be too harsh and may damage the pan's seasoning.

When using soap to clean your cast iron pan, follow these steps:

• Use a pan scraper or a nylon brush to remove stuck-on food residue. If the food is stubborn, simmer a small amount of water in the pan for 3-5 minutes, then use the scraper after the pan has cooled.
• Pour a small amount of mild dish soap into the pan.
• Add a small amount of warm water.
• Use a nylon brush, sponge, or scrub brush to clean the pan, inside and out. Avoid using steel wool or metal scrubbers, as these can damage the seasoning and make the pan non-stick.
• Promptly dry the pan with a lint-free cloth, paper towel, or tea towel. It is important to dry the pan thoroughly to prevent rust.
• Rub a light layer of cooking oil, such as flaxseed, canola, or vegetable oil, on the surface of the pan. Use a paper towel to wipe away any excess oil.

By following these steps and using a small amount of mild soap, you can effectively clean your cast iron pan without damaging its seasoning.

Dry the pan with a lint-free cloth

Drying your cast-iron pan is a crucial step in its maintenance. Leaving water in the pan can cause rusting, so it is important to dry it thoroughly. To dry your pan, use a lint-free cloth or paper towel to wipe it down. If you notice any black residue on your towel, don't worry—this is normal and is just the seasoning coming off. Make sure to dry the inside and outside of the pan, including the handle. You can also place the pan on the stove over medium heat for a few minutes to ensure that all the moisture evaporates. This step is crucial, as any remaining moisture can cause rust.

Once your pan is completely dry, you can move on to the next step of maintenance, which is seasoning the pan with a light layer of cooking oil.

Use a pan scraper for stuck-on food

Using a pan scraper is an effective way to remove stuck-on food from your cast iron pan without damaging the surface. Pan scrapers are made from hard plastic, which makes them ideal for removing burnt-on food from pans. They are also dishwasher-safe, so you don't have to worry about any yucky residue on your sponges or in the dishwater.

There are several types of pan scrapers available, each with unique features. For example, the Lodge SCRAPERPK Durable Pan Scrapers come in a pack of two and feature a combination of red and black polycarbonate construction. The different corners of the scrapers are designed to clean various surfaces, including flat pans and those with crevices. These scrapers are also safe for all types of cookware, whether non-stick or not.

Another option is the KitchenVIA 3-piece pan scraper tool set, which includes scrapers made from heavy-duty polypropylene plastic and TPR. These scrapers are safe for use on various surfaces, including glass, stainless steel, iron, and steel, and are resistant to stains and odours.

The G.CATACC pan scraper is another great choice, featuring two materials in one piece. One side has a hard plastic edge to remove stubborn stains, while the other has a flexible soft silicone edge to clean non-stick cookware without scratching. This scraper also has four differently shaped corners, allowing it to fit into various pan shapes.

When using a pan scraper, it is important to note that they should not be used on hot pans as they will melt. Additionally, while some pan scrapers are dishwasher-safe, it is recommended to wash them by hand to prevent melting.

Don't soak the pan in water

Cast iron pans are a versatile workhorse in the kitchen. They can be used for anything from baking cornbread to roasting vegetables, searing steaks, or frying chicken. However, they do require some special care when it comes to cleaning and maintenance. One of the most important things to remember is to never soak your cast iron pan in water. Here's why:

Cast Iron Is Porous: Cast iron is a porous material that can absorb water. This means that despite its durability, your cast iron pan has the potential to absorb water, which can lead to rust. Soaking your pan is, therefore, a surefire way to end up with a rusty skillet. It is best to wash your cast iron pan by hand and ensure it is thoroughly dried before putting it away. Even a single drop of water left in the pan can lead to a rust spot.

How to Avoid Soaking: To avoid the temptation of soaking, fill your cast iron pan with a small amount of water and simmer it for a few minutes to loosen any stubborn, stuck-on food. You can then use a nylon scrubbing brush or a pan scraper to remove the remaining food bits. Remember to dry your pan promptly and thoroughly with a lint-free cloth or paper towel. If you notice any black residue on your towel, don't worry—it's just the seasoning and is perfectly normal.

What to Do if You Soaked Your Pan: 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 and restore your pan. Use steel wool or a metal scrubber to scrape away the rusty areas. Once the rust is removed, wash the pan with soap and warm water, and dry it thoroughly. The final step is to re-season your pan by spreading a thin layer of cooking oil over its surface and baking it at 450 to 500 degrees Fahrenheit until cool.

Soaking Affects the Seasoning: Another reason to avoid soaking your cast iron pan is that it can impact the seasoning. Seasoning is a thin layer of polymerized oil that gives your cast iron pan its non-stick properties. Soaking your pan for an extended period can break down this layer, requiring you to re-season your pan more frequently. To maintain the seasoning, it is best to wash your pan promptly after each use and ensure it is thoroughly dried.

In summary, while cast iron pans offer numerous benefits in the kitchen, they require proper care to maintain their durability and performance. By avoiding soaking your pan, you can prevent rust and maintain the seasoning that gives your cast iron pan its non-stick qualities. With proper care, your cast iron cookware will last a lifetime and can even be passed down to future generations.

Re-season the pan

Re-seasoning a cast-iron pan is a straightforward process that will help you restore its non-stick properties and keep it in good condition for years to come. Here's a detailed guide on how to re-season your pan:

Step 1: Scrub the Pan

Start by giving your pan a good scrub with warm, soapy water. You can use a nylon brush or fine steel wool to remove any stuck-on food or rust. If your pan has a lot of rust, you may want to try soaking it in a mixture of equal parts vinegar and water for up to eight hours. Once you've removed all the residue, rinse the pan and dry it thoroughly with a clean cloth or paper towel. Make sure to dry both the inside and outside of the pan, including the handle.

Step 2: Apply Oil

The next step is to apply a thin, even layer of cooking oil to the pan. You can use vegetable oil, canola oil, grapeseed oil, or melted shortening. Avoid using too much oil, as this can make the pan sticky. Make sure to coat the entire pan, inside and out, as well as the handle. Use a paper towel to buff off any excess oil so that the pan is not greasy to the touch.

Step 3: Place the Pan in the Oven

Preheat your oven to between 450-500°F (230-260°C). Place the pan upside down on the middle rack of the oven to prevent oil from pooling inside. Place a sheet of aluminum foil or a baking sheet on the lower rack to catch any drips. Leave the pan in the oven for about an hour. The oil will polymerize and form a hard, plastic-like coating during this time.

Step 4: Cool and Repeat

After an hour, turn off the oven and leave the pan inside to cool completely. Once the pan is cool, you can wipe away any excess oil with a paper towel. Depending on the condition of your pan, you may need to repeat the above steps several times to achieve the desired level of seasoning. A well-seasoned pan will have a dark, matte finish and a semi-gloss look.

Step 5: Maintenance

Once your pan is seasoned, it's important to maintain it properly. After each use, wash the pan with hot water (no soap) and dry it thoroughly. You can also oil the pan after each use to maintain the seasoning. If you notice your food starting to stick to the pan or the patina wearing off, it's time to re-season it again.
