Reviving Sticky Cast Iron: A Guide To Restoring Your Pan's Glory

Cast iron pans are a versatile kitchen tool that can be used anywhere from ovens to grills and even on an open flame. However, they can become sticky over time. This can be caused by a variety of factors, such as not using enough fat or oil when cooking, using a pan that isn't well-seasoned, or breaking in new cookware. Luckily, there are several ways to recondition a sticky cast iron pan.

Removing rust with vinegar

Step 1: Prepare the Vinegar Mixture

Mix equal parts water and white vinegar in a separate container, such as a bucket or a pan. The vinegar will help to dissolve the rust from your cast iron.

Step 2: Soak the Pan

Completely submerge your cast iron cookware in the vinegar mixture, ensuring that the handle is also covered. Leave it to soak for up to 8 hours. It is important to check on your pan regularly, as the rust may come away before the full 8 hours have passed.

Step 3: Scrub and Wash

Once the rust has been removed, take your pan out of the vinegar mixture and wash it with mild dish soap and warm water. Use a soft scrubber or brush to gently remove any remaining rust. Be careful not to scrub too hard, as this could damage the surface of your pan.

Step 4: Dry the Pan

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

Step 5: Re-season the Pan

After cleaning your cast iron, you will need to re-season it. Start by preheating your oven to between 350°F and 500°F. Then, rub a thin layer of cooking oil or vegetable oil on the entire surface of the pan, inside and out.

Step 6: Bake the Pan

Place the oiled pan upside down on the top rack of your oven. Put a baking sheet or aluminium foil on the bottom rack to catch any excess oil that may drip. Leave the pan in the oven for about an hour, then turn off the heat and allow it to cool.

Tips for Maintaining Your Cast Iron Pans:

• Always clean and dry your cast iron pans properly after use.
• Store your cast iron pans in a dry, low-humidity spot to prevent rust from forming.
• Stacking multiple pans? Use pan separators or layers of paper towels to allow airflow and prevent moisture buildup.

Cleaning with baking soda

If your cast iron pan has a coating of enamel, baking soda is a great option for cleaning. Here is a step-by-step guide:

• Fill your pan with water, making sure to completely submerge the burned or affected areas.
• Turn the burner to high and bring the water to a rolling boil.
• Add two tablespoons of baking soda. Stir the mixture with a wooden spoon and let it continue boiling for a few minutes.
• Turn off the burner and carefully dump out the water.
• Immediately scrub the bottom and sides of your pan with a sponge.
• Repeat the process until your pan is totally clean.

If your pan has more serious surface rust, you can try the following method suggested by TikToker @smokedbbqsource:

• Make a paste with six tablespoons of baking soda and three tablespoons of water.
• Scrub the pan with steel wool.
• Add vinegar and scrub some more to remove the rust.
• Rinse with warm water, then wipe down the pan completely.
• Season the pan with some oil and place it in an oven preheated to 500 degrees Fahrenheit for one hour.
• Let the pan cool completely, then repeat the process if necessary.

Re-seasoning with oil

Re-seasoning your cast iron pan with oil is a straightforward process. Here is a detailed, step-by-step guide:

Step 1: Clean and Dry

First, ensure your pan is clean and completely dry. Start by washing the pan with warm, soapy water. You can use a pan scraper or a nylon scrubbing brush to remove any stuck-on food residue. Rinse the pan under warm water and ensure it is thoroughly dried with a lint-free cloth or paper towel. If needed, you can place the pan on the stovetop on low heat for a few minutes to ensure it is completely dry.

Step 2: Apply a Thin Layer of Cooking Oil

The next step is to add a thin, even layer of cooking oil to the entire surface of the pan, inside and out. Use a cloth or lint-free paper towel to apply the oil. Be careful not to use too much oil, as this can cause the pan to become sticky. A thin layer is important for baking the oil into the pan effectively.

Step 3: Preheat Oven and Prepare Baking Sheet

Preheat your oven to 450-500 degrees Fahrenheit. Place a large baking sheet or a piece of aluminum foil on the bottom rack of the oven to catch any excess oil that may drip during the baking process.

Step 4: Bake the Pan

Place the oiled pan upside down on the centre rack of the preheated oven. Bake it for at least 30 minutes to up to one hour. You may see some smoke during this time as the oil begins to polymerize and form a coating. This process allows the oil to bond to the metal and creates a non-stick surface.

Step 5: Cool and Repeat if Necessary

Once the smoking stops and the time is up, turn off the oven and allow the pan to cool down slowly inside. This helps to solidify the layers of seasoning. If needed, you can repeat the process of coating the pan with oil and baking it for another layer of seasoning.

By following these steps, you can effectively re-season your cast iron pan with oil, restoring its non-stick properties and protective coating.

Avoiding common mistakes

• Do not soak your cast iron pan in water, put it in the dishwasher, or leave it to air dry. This will cause rust.
• Do not store your cast iron pan in a moisture-prone environment, such as a cabinet near a dishwasher, an open cabinet in a humid location, or outside.
• Do not use steel wool or a metal scrubber to clean your cast iron pan unless you are removing rust before reseasoning.
• Do not put your cast iron pan in the oven without first removing excess oil. This can cause stickiness.
• Do not use too much oil when seasoning your pan. This will also cause stickiness.
• Do not heat your cast iron pan without oil on the cooking surface. This will cause dullness.
• Do not put your cast iron pan in the dishwasher. This will remove the seasoning and likely cause rust.
• Do not use soap to clean your cast iron pan unless you are preparing to re-season it.

Long-term care

Cast iron pans can last forever when properly cared for. A well-seasoned skillet has a distinct look: it is noticeably dark with a shiny, semi-gloss finish. To maintain this finish, it is best practice to oil your pan after each use. If you rarely use your cast-iron skillet, oiling it only two to three times a year will work.

After each use, avoid using dish soap. Instead, rub the pan with coarse kosher salt to remove cooking debris and apply a thin layer of shortening or oil if desired. If your cast-iron cookware has a lid, always store it separately—never on top of the pan—to prevent humidity from building up and creating rust.

To clean your cast iron pan, wash it by hand with a small amount of soap. Use a pan scraper for stuck-on food. For stubborn, stuck-on food, simmer a little water for 3-5 minutes, then use the scraper after the pan has cooled. Dry promptly and thoroughly with a lint-free cloth or paper towel. If you notice a little black residue on your towel, it's just seasoning and is perfectly normal.

If your pan does develop rust, don't panic. With a little extra care, you can remove the rust and continue using your cast iron cookware. Scour the rusty pan with warm, soapy water and steel wool. Rinse and hand dry thoroughly. Apply a very thin, even layer of cooking oil to the cookware (inside and out). If you use too much oil, your cookware may become sticky. Place the cookware in the oven upside down on the top rack. Place a large baking sheet or aluminum foil on the bottom rack to catch any excess oil that may drip off the cookware. Bake at 450-500 degrees F for one hour. Allow to cool and repeat as necessary to achieve the classic black patina.
