Scrubbing Away The Gunk: Revitalizing Your Cast Iron Pan

Removing gunk from a cast-iron pan can be a challenge, but it's not impossible. There are several methods you can try, depending on how burnt the gunk is. For lightly burnt areas, you can simply use hot water and a stiff brush to scrub it away. For more stubborn stains, you can try using baking soda or coarse salt, or even boiling water in the pan to loosen the gunk. If you're dealing with a lot of built-up grease and gunk, you might need to strip the pan by placing it in a trash bag with oven cleaner or vinegar. Once the gunk is removed, it's important to dry the pan completely and reseason it with oil to prevent rusting.

Use hot water and a stiff brush to scrub away gunk

To remove gunk from a cast-iron pan, one effective method is to use hot water and a stiff brush. Here is a detailed guide on how to do this:

Firstly, ensure your cast-iron pan has cooled down before cleaning it. Never immerse a hot skillet in water, as it may crack the pan. Once the pan is cool, run hot water into the pan, ensuring the temperature is as hot as possible. Allow the pan to fill with water to just cover the bottom surface.

Place the pan on the stove and turn the heat on to a medium-high setting. Bring the water to a boil. The boiling water will help loosen the gunk, making it easier to scrub away. Once the water is boiling, you can turn off the heat and let the water cool slightly before proceeding.

Using a stiff brush, begin to scrub the affected areas of the pan. You can use a vegetable brush or a brass brush for this purpose. The stiff bristles will help dislodge the gunk without damaging the cast iron. Scrub vigorously, but be careful not to scratch the pan's surface. If the gunk is particularly stubborn, you can try adding a small amount of dishwasher detergent (dry powder, not liquid soap) to the water. However, be aware that this may affect the seasoning of your pan.

If the gunk is still not coming off, you can try repeating the process, ensuring you bring the water to a boil again. For heavily burnt-on gunk, you may need to perform this step several times.

Once you have removed the gunk, thoroughly dry the pan by placing it back on the stove over low heat until all moisture has evaporated. Then, while the pan is still hot, wipe the inside with a light coating of vegetable oil to restore and protect its finish. Allow the pan to cool completely before putting it away.

By following these steps, you can effectively remove gunk from your cast-iron pan using hot water and a stiff brush, restoring it to its original condition.

Spread baking soda or coarse salt over the pan and scrub

Removing gunk from a cast-iron pan can be done in a few simple steps. Firstly, spread baking soda or coarse salt over the base of the pan. You can use kosher salt, coarse sea salt, or baking soda for this. Next, use a paper towel or a soft scrub brush to scrub the base of the pan. You can also use a vegetable brush or a cast-iron scrubber for this step. If you are using a scrub brush, ensure that it is not made of metal, as this can scratch the surface of the pan and strip away the seasoning. If you are using a paper towel, you may want to add a little water to the baking soda to form a paste. Scrub the burnt area with the paste until the gunk is removed.

Once the gunk is removed, rinse the pan with water to remove any leftover salt or baking soda. Make sure to only use hot water, as cold water can crack the skillet. You should also avoid letting the pan sit in water for too long, as this can cause rusting. Dry the pan thoroughly with a dedicated dish towel or paper towel. You can also place the pan over a high flame for a few minutes to ensure it is completely dry. Finally, apply a thin coat of oil to the pan while it is still warm.

Boil water in the pan and scrub

Boiling water in your cast-iron pan and scrubbing is an effective way to remove gunk and stuck-on food. Here is a step-by-step guide:

First, fill your cast-iron pan with water to a height of around 1 inch (2.5 cm). Turn on your stove and place the pan on a stovetop burner set to high heat. Allow the water to reach a rolling boil; this should take around 10 minutes. During this time, the water's heat will help loosen the stubborn, burnt-on gunk.

Once the water is boiling, you can use a wooden or plastic utensil, such as a spatula, to gently nudge and scrape away at the gunk. Never use metal utensils for this, as they can scratch the surface of your cast-iron pan and damage its seasoning.

After dislodging the gunk, you can begin scrubbing. Use a stiff brush, such as a chain mail cast-iron scrubber, to firmly scrub away at the burnt areas. If you like, you can add a drop or two of modern dish soap as you scrub. While some sources advise against using dish soap on cast iron, modern dish soap is usually gentle enough, and the pan's seasoning will protect the metal.

If you don't want to use dish soap, you can also use coarse salt or baking soda as a scrubbing agent. Sprinkle a layer of kosher salt, coarse sea salt, or baking soda over the base of your skillet. Then, use a paper towel or soft scrub brush to scrub away at any remaining stuck-on food. Finish by lightly rinsing the pan with water to remove any leftover salt or baking soda.

After scrubbing, be sure to thoroughly dry your cast-iron pan. Any water left on the skillet when you put it away may cause rusting. You can dry the pan by placing it in an oven set to 300 °F (149 °C) for about an hour, or on a stovetop burner over medium-high heat for around 10 minutes.

Once the pan is completely dry, it's a good idea to apply a thin coat of oil to the surface. This will help protect the pan and enhance its non-stick qualities. Vegetable oil, canola oil, and grapeseed oil are ideal choices due to their high smoke points. To apply the oil, simply pour a small amount (around 1 to 2 US tablespoons) into the skillet and use a paper towel to spread it evenly across the surface.

Dry the pan and apply a thin coat of oil

Once you have cleaned your cast-iron pan, it is important to dry it completely. Leaving water on the pan can cause rusting. To dry the pan, use a dry cloth to remove excess water, then place the pan in an oven preheated to 300 °F (149 °C) for an hour. Alternatively, you can place the pan on the stovetop over medium-high heat for around 10 minutes until all the water evaporates.

After the pan is completely dry, it is time to apply a thin coat of oil. This helps to protect the pan and create a smooth cooking surface. Choose a neutral oil with a high smoke point, such as vegetable oil, canola oil, or grapeseed oil. Pour 1 to 2 US tablespoons (15 to 30 mL) of oil into the skillet and use a paper towel to spread it evenly over the entire surface. Be sure to use just a thin layer of oil, as too much can cause the pan to become sticky.

Place the pan in a bag and spray with oven cleaner

To remove gunk from a cast-iron pan, one method is to use oven cleaner. This method is toxic and requires careful handling, but it is effective and relatively hands-off. Here is a detailed, step-by-step guide:

Place the cast-iron pan in a large plastic bag, such as a trash bag. Ensure the bag is big enough to fully contain the pan. Tie the bag closed securely. This step is important to contain the oven cleaner and protect the surrounding area from its toxic effects.

Put on protective rubber gloves to shield your hands from the oven cleaner. Take a can of oven cleaner and, standing well back to avoid inhaling the fumes, spray the cleaner liberally onto the cast-iron pan. Make sure to coat the pan thoroughly, including the handle and all other surfaces.

Keep the pan in the bag and leave it to sit for several hours, or even up to 24 hours if there is severe gunk buildup. The longer you leave it, the more effective the oven cleaner will be at breaking down the gunk. If the weather is warm, you can place the bag outside in the sun to help keep the oven cleaner active. If it is cold, put the bag in a plastic tub and bring it inside to keep it warm.

After the allotted time has passed, put on your gloves and carefully remove the pan from the bag. Rinse the pan thoroughly with a vinegar solution to neutralise the lye in the oven cleaner. Then, scrub the pan inside and out with dish soap and a stainless steel scrubber. For safety, scrub the pan with soap a second time and rinse it again to ensure all traces of oven cleaner are gone.

Finally, dry the pan thoroughly with a towel. You can place the pan in a warm oven or on low heat on the stovetop to ensure it is completely dry. Once dry, follow the steps to re-season your cast-iron pan.

This method is an effective way to remove stubborn gunk from a cast-iron pan. However, always exercise caution when using oven cleaner due to its toxicity. It is important to protect your skin, avoid inhaling the fumes, and ensure good ventilation during the process.
