Why cleaning and maintaining a cast iron skillet is important
Cleaning and maintaining your cast iron skillet is essential for several reasons. First and foremost, proper care preserves the skillet’s seasoning—a thin layer of oil that has baked into the cookware. This seasoning is responsible for the cast iron’s signature non-stick quality and also helps to prevent rusting and corrosion.
Using a cast iron skillet, the even heat distribution on the cooking surface is crucial for achieving consistent cooking results. Without regular maintenance, the skillet’s performance could decline. Harsh cleaning methods, including the use of dishwashers, soap, or steel wool, can strip the pan’s seasoning, reducing its non-stick properties and leading to food sticking and burning.
When cleaning your skillet, simple tools like a paper towel, warm water, and a Wooden spatula are preferable. For stubborn, stuck-on food bits, a paste made from coarse kosher salt and water can be gently used to scrub the pan without damaging its seasoning. Cast iron requires a protective layer of oil after each cleaning to keep it in optimal condition. Neglecting the proper care of your cast iron can result in a rusty, less functional pan, diminishing its longevity and the quality of the food you cook. Regular cleaning ensures your seasoned cast iron skillet remains a versatile and durable asset in your kitchen.
Everyday Cleaning and Seasoning
Cast iron cookware, particularly skillets, is favored for its durability and improvement over time—provided it is cared for correctly. Every cast iron skillet should be promptly cleaned after use. Rather than employing harsh soaps or abrasive scrubbers, which can strip away the pan’s precious seasoning, daily maintenance can be as simple as wiping the skillet with a paper towel or rinsing it with hot water. After each use, maintaining the skillet’s seasoning is crucial for ensuring a quality non-stick cooking surface and is accomplished by rubbing a small amount of oil into the pan. By routinely seasoning your cast iron skillet and not just after heavy-duty cleaning, this procedure builds the non-stick qualities and keeps rust at bay.
Remember, seasoning is not a one-time process; it’s ongoing maintenance. The more regularly you use the skillet, the stronger the seasoning becomes. This not only enhances the non-stick characteristic but also forms an effective barrier preventing rust. Cleaning with hot water and a mild sponge, followed by complete drying, will ensure your cast iron skillet remains rust-free and continues to improve with age.
Scrub off stuck-on food with hot water and a nylon brush
For those occasions when bits of food stubbornly cling to your pan, refrain from soaking the skillet, which can lead to rust formation and impact the pan’s longevity. Instead, utilize hot water combined with a non-abrasive nylon scrubbing brush to gently remove any stuck-on food. This method safeguards the skillet’s seasoned surface.
It’s best to tackle this cleaning while the skillet is still warm—just be cautious to prevent burns. Fill the pan with warm water immediately after cooking, and let it sit for a couple of minutes to loosen the food bits. Then, using the nylon brush, gently scrub the warm cast iron skillet to lift away any residue. Remember, the goal is to preserve the integrity of the skillet’s seasoning, so gentle and patient scrubbing here will go a long way towards maintaining your pan’s coveted properties.

- Apply oil evenly: Coat the entire skillet, both inside and out, including the handle, with a neutral, high-smoke point oil. Vegetable oil, canola oil, or a commercial Seasoning Spray are all suitable choices.
- Heat it in your oven: Place the skillet upside down in a preheated oven at 350°F to allow the oil to polymerize properly. Place a sheet of aluminum foil or a baking sheet on the rack below to catch any drips.
- Let it bake: Leave the skillet in the oven for at least one hour. After this time, turn off the oven and allow the skillet to cool inside it slowly.
Following these steps not only prevents your skillet from rusting again but also reinforces the non-stick surface that makes cast iron cookware so cherished.
Apply a layer of oil or fat and heat the skillet in the oven
When it comes to seasoning your cast iron skillet, the application of oil is key. Choose a neutral oil or fat with a high smoke point, like vegetable oil, canola oil, or even shortening. To apply:
- Warm the skillet: Warm your skillet on the stove over low to medium heat to open the pores of the iron, which helps with absorption.
- Apply the oil: With a clean paper towel, apply a thin, even layer of oil across every surface of the skillet. A little oil goes a long way – you’re aiming for a thin sheen rather than a deep fry.
- Wipe off excess: Use another paper towel to wipe out any excess oil. Too much oil can result in a sticky residue.
Once your skillet is evenly coated, place it upside down in an oven preheated to 350°F. Bake for an hour, which allows the oil to break down and bond with the iron, creating that classic, slick cast iron feel. After the hour, let the skillet cool in the oven without opening the door. This process generates a durable layer of seasoning that serves as the foundation for countless future meals.
Repeat the seasoning process multiple times for a well-seasoned skillet
For a truly well-seasoned skillet, repetition is the secret. Here’s what to consider:
- Frequency: Seasoning isn’t a one-and-done deal. To achieve that coveted, glassy surface, you’ll want to repeat the oiling and heating process a few times, especially early in the skillet’s life.
- Layering: Each time you season, you’re adding another layer to the skillet’s defense against food and moisture. Over time, these layers polymerize further, creating a non-stick surface that’s hard to rival.
- Post-cooking: After each use of your skillet, consider giving it a light wash, drying it thoroughly, and then giving it a stovetop heat treatment with a bit of oil. This mini-seasoning session keeps your skillet in optimal condition.
By diligently favoring the layering of seasoning, your skillet won’t just be a kitchen tool – it’ll become an heirloom worthy of passing down through generations.
Stripping a Cast Iron Pan
Stripping a cast iron skillet is akin to hitting the reset button on your cherished cookware. Over time, even the best maintained cast iron can accumulate a stubborn layer of carbonized seasoning and, in some cases, rust that impedes its cooking performance. To restore the skillet to its raw cast iron glory, you’ll need to completely strip away the old seasoning. This can be achieved using a commercial oven cleaner or through the process of electrolysis. Both methods are highly effective but require careful handling and preparation.
Whichever method you choose, the goal is straightforward: to reveal the bare cast iron beneath so that you can start the seasoning process anew. For rusted skillets, fine steel wool and a little bit of mild dish soap will do wonders in preparing the surface for its next seasoning chapter. This process is crucial not only for aesthetic reasons but also for maintaining the integrity and longevity of your skillet. Remember, a stripped skillet is a blank canvas, and seasoning it correctly will ensure a lifetime of superior cooking and frying.
Use oven cleaner or electrolylysis to strip the skillet
The oven cleaner method is a popular DIY solution for stripping a cast iron skillet. This method centers around the powerful degreasing action of the oven cleaner, which typically contains lye (sodium hydroxide) to break down years of built-up residue. To safely employ this technique, it’s crucial to perform the task in a well-ventilated area, preferably outdoors. Donning rubber gloves and a respirator mask will protect your skin and lungs from the harsh chemicals.
To begin, apply a generous amount of oven cleaner over the entire skillet, ensuring every surface is coated. Encase the skillet in a plastic bag to keep the cleaner from drying out and let it sit, checking periodically to assess the progress. The duration can vary, but often the skillet will need to reside in the bag for a number of hours to a full day. After the cleaner has done its work, scrub the pan with steel wool to remove the dissolved seasoning. Wash the skillet thoroughly with warm soapy water to remove any remaining cleaner and immediately dry it with a clean towel to prevent rust from forming.
Electrolysis, on the other hand, is a more controlled and chemical-free process that also takes a bit more setup. It involves immersing the skillet in a solution of water and washing soda, and passing an electrical current through it, which removes rust and old seasoning through a gentle electrochemical reaction. Safety is paramount with this method, as it involves electricity and water, and should only be carried out by those comfortable with the process and its inherent risks.
Re-season the skillet after stripping
Once the skillet is stripped of its old seasoning, attention must turn to re-seasoning—a critical step to protect the bare iron from rust and to start building up a new, slick cooking surface. Begin by applying a slurry of Bar Keepers Friend, a mild abrasive cleaner, mixed with water. Scrub the surface with a stainless steel scrubber, while wearing rubber gloves to protect your hands. This will help remove any remaining rust spots and prepare the skillet for seasoning.
Wash the skillet with mild dish soap and hot water, then dry it completely. Failure to dry the skillet immediately can lead to flash rust—a quick-forming coat of rust that occurs on bare iron exposed to air and moisture. After drying, the skillet should be seasoned immediately.
To re-season, preheat your oven to 375°F and place a layer of aluminum foil on the bottom rack to catch any drips. Apply a thin film of neutral oil (like vegetable or canola) to the entire surface of the skillet, including the underside and handle, then wipe away the excess with a paper towel—you’re aiming for a coat that’s just enough to shimmer, not drip. Place the skillet upside down on the top rack and bake for an hour. After completing this cycle, turn off the oven and let the skillet cool down inside.
If the skillet was severely rusted or you want to ensure a strong initial seasoning, you may opt to repeat the heating, oiling, and cooling process two or three times before the first use. With each seasoning round, you’re building up layers of polymerized oil that form the skillet’s non-stick patina and seal out moisture to prevent future rust. Your cast iron skillet is now refreshed and ready for many more years of loyal service in the kitchen.
Use oven cleaner or electrolysis to strip the skillet
If you find your cast iron skillet with decades of carbon buildup, reaching for oven cleaner can be an effective solution to strip away burnt-on grease. However, using oven cleaner, which is highly toxic and contains lye (sodium hydroxyde), demands careful handling. Here’s how you can strip your skillet efficiently and safely:
- Safety First: Always work in a well-ventilated area or outdoors to avoid inhaling fumes. Wear protective gear such as rubber gloves and a respirator mask to prevent skin burns and inhalation of toxic substances.
- Preparation: You’ll need minimal equipment – just the oven cleaner, gloves, and masks, ensuring an easier setup in comparison to other methods.
- Application: Spray a generous amount of oven cleaner on the skillet, covering all surfaces.
- Waiting Time: Allow the cleaner to work on the skillet as per the instructions on the cleaner. This usually involves letting it sit for a few hours or overnight.
- Cleaning Up: After the wait, rinse the skillet thoroughly with warm water to remove all traces of the oven cleaner.
- Aftercare: Once rinsed, you might need to re-season your skillet before its next use.
Remember, while oven cleaner is an effective method to strip a cast iron skillet, it requires vigilant adhering to safety precautions. Alternatively, for those who prefer a less toxic method, electrolysis can also be used to strip and refurbish cast iron cookware.
Cleaning Enameled Cast Iron
Enameled cast iron cookware combines the heat retention and cooking abilities of traditional cast iron with the ease of cleaning and care provided by its enamel coating. The enamel creates a smooth and non-porous surface, ensuring that food doesn’t stick as readily and simplifying the washing process. Unlike uncoated cast iron skillets, enameled versions can be cleaned with hot, soapy water—much like other non-cast iron cookware. However, when it comes to stubborn food stains or bits that refuse to let go, a gentle simmer with a mix of water and a bit of dish soap, or even a sprinkle of baking soda will often do the trick. After the session of simmering, simply scrub and rinse thoroughly with care.
Although most enameled cast iron pans are technically dishwasher-safe, hand washing is recommended to avoid wearing down the enamel finish. Cleaning by hand also helps prevent the potential dulling or chipping that could occur with machine washing. Always refrain from abrasive cleaners and hard scrub brushes or steel wool, which could damage the delicate enamel coating on your cookware.
Use mild dish soap and a soft brush to clean enameled cast iron
When caring for your enameled cast iron, embrace the gentle touch. A simple combination of hot water and regular dish soap is generally all that’s needed for routine cleaning. Apply this with a non-abrasive sponge or soft brush to maintain the integrity of the enamel. For those times when your cookware encounters more challenging marks or residues, refrain from reaching for citrus juices or citrus-based cleaners, which have the potential to dull the enamel’s glossy finish. Instead, you can simmer a small amount of water mixed with dish soap or baking soda on a low flame for a short duration to help break up the residue before continuing with the soft sponge and soapy water.
Avoid abrasive cleaners or scrub brushes
The traditional method of seasoning cast iron by baking oil onto the pan to form a nonstick surface differs from the practical care of enameled cast iron. While the seasoning on standard cast iron is reasonably durable, it’s important to remember that regardless of the type, abrasive cleaners and harsh detergents can harm cast iron pans and should be avoided to maintain their lifespan and cooking properties. Regular kosher salt can be enlisted for a gentle yet effective scouring of caked-on food. But beware—scrubs or chainmail scrubbers, if not used cautiously, may pose a risk to the seasoned surface. As a rule of thumb, use gentle techniques and avoid anything that might scratch or strip away the seasoned layer or enamel. Cast iron soap products containing oils or waxes might leave behind an unwelcome greasy film, so sticking to straightforward dish soap is generally the best practice.
