Cast iron skillets have been a staple in many kitchens for centuries, and for good reason. They’re incredibly durable, versatile, and can distribute heat evenly, making them ideal for a wide range of cooking techniques. However, after years of use, your trusty cast iron skillet can become caked with grease and grime, making it difficult to cook with and clean. In this article, we’ll take you through a step-by-step guide on how to clean an old greasy cast iron skillet, restoring it to its former glory.
Understanding the Importance of Proper Cleaning and Maintenance
Before we dive into the cleaning process, it’s essential to understand the importance of proper cleaning and maintenance for your cast iron skillet. Unlike other cookware, cast iron requires a bit more TLC to maintain its non-stick seasoning and prevent rust. Avoid using harsh chemicals, abrasive cleaners, or scouring pads, as these can strip away the seasoning and damage the metal. Instead, we’ll focus on using gentle yet effective methods to clean and maintain your cast iron skillet.
Preparing Your Skillet for Cleaning
Before you start cleaning your cast iron skillet, make sure to remove any large food particles or debris. Scrape out any excess food with a soft spatula or paper towel, taking care not to scratch the surface. If there are any stubborn stuck-on bits, you can mix 1 tablespoon of kosher salt with 1 tablespoon of water to create a paste. Apply the paste to the affected area and let it sit for 30 minutes before wiping it clean with a paper towel.
Method 1: Cleaning with Hot Water and Elbow Grease
For a gentle and non-toxic cleaning method, try using hot water and elbow grease. This method is ideal for removing grease and grime without stripping away the seasoning.
Step-by-Step Instructions

Re-Seasoning Your Cast Iron Skillet
After cleaning your cast iron skillet, it’s essential to re-season it to maintain the non-stick surface. Re-seasoning your skillet every 1-2 months will help prevent rust and ensure even cooking.
Step-by-Step Instructions

What is the best way to clean a cast iron skillet?
The best way to clean a cast iron skillet is to avoid using harsh chemicals or abrasive cleaners, as they can strip away the seasoning. Instead, start by wiping out any excess food particles with a paper towel. Then, mix a small amount of kosher salt and water to create a paste, and use it to scrub away any stuck-on grime. Rinse the skillet with warm water, and dry it thoroughly with a towel.
For tougher grime buildup, you can mix equal parts water and white vinegar in the skillet, and bring it to a boil. Reduce the heat and let it simmer for 10-15 minutes, then scrub the skillet with a soft sponge or brush. Rinse the skillet with warm water, and dry it thoroughly with a towel. This method is gentle enough not to strip away the seasoning, but tough enough to remove stubborn grime.
How do I remove stubborn grease and grime from my cast iron skillet?
To remove stubborn grease and grime from your cast iron skillet, start by applying a small amount of cooking oil to the affected area. Let it sit for a few hours or overnight, allowing the oil to penetrate and loosen the grime. Then, use a soft sponge or brush to scrub away the grime, working in a circular motion. Rinse the skillet with warm water, and dry it thoroughly with a towel.
If the grime is particularly stubborn, you can try using a mixture of equal parts water and baking soda to create a paste. Apply the paste to the affected area, and let it sit for 30 minutes to an hour. Then, scrub the skillet with a soft sponge or brush, and rinse it with warm water. Dry the skillet thoroughly with a towel, and apply a thin layer of cooking oil to the affected area to prevent rust.
Can I use a dishwasher to clean my cast iron skillet?
No, it’s not recommended to use a dishwasher to clean your cast iron skillet. The high heat and harsh detergents in a dishwasher can strip away the seasoning on your skillet, causing it to rust. Additionally, the intense water jets in a dishwasher can damage the skillet’s finish, causing it to become rough and uneven.
Instead, clean your cast iron skillet by hand using the methods described above. This will help to preserve the seasoning and prevent rust, ensuring that your skillet continues to perform well for years to come. If you’re short on time, you can also clean your skillet in the sink using warm water and a soft sponge or brush.
How do I dry my cast iron skillet after cleaning?
To dry your cast iron skillet after cleaning, start by towel-drying it as thoroughly as possible. Then, place the skillet over low heat on your stovetop, allowing it to dry completely. This will help to prevent water spots from forming on the skillet’s surface.
Alternatively, you can dry your cast iron skillet in the oven. Preheat your oven to its lowest temperature setting (usually around 200°F), and place the skillet upside down on the middle rack. Let it dry for 30 minutes to an hour, then turn off the oven and let the skillet cool completely. This method is especially effective for drying the skillet’s handle and any other hard-to-reach areas.
Can I use soap or harsh chemicals to clean my cast iron skillet?
No, it’s not recommended to use soap or harsh chemicals to clean your cast iron skillet. Soap and harsh chemicals can strip away the seasoning on your skillet, causing it to rust. Additionally, these substances can leave behind residues that can affect the flavor of your food.
Instead, clean your cast iron skillet using the methods described above, which are gentle enough not to strip away the seasoning. If you need to remove stubborn grime or stains, try using a mixture of equal parts water and white vinegar, or a paste made from kosher salt and water. These methods are tough enough to remove grime, but gentle enough not to damage the skillet’s finish.
How often should I clean my cast iron skillet?
You should clean your cast iron skillet after every use, even if it’s just a quick wipe with a paper towel. This will help to prevent food particles from building up and causing grime to form. For tougher grime buildup, you can clean your skillet every 1-3 months, depending on how often you use it.
Regular cleaning will help to maintain the seasoning on your skillet, preventing rust and ensuring that it continues to perform well. Additionally, cleaning your skillet regularly will help to prevent the buildup of bacteria and other microorganisms, keeping your food safe to eat.
Can I put my cast iron skillet in the refrigerator or freezer?
No, it’s not recommended to put your cast iron skillet in the refrigerator or freezer. The moisture in these environments can cause the skillet to rust, especially if it’s not properly seasoned. Additionally, the extreme temperatures can cause the skillet’s metal to contract and expand, potentially causing it to warp or crack.
Instead, store your cast iron skillet in a dry place, such as a hook or hanging rack. Apply a thin layer of cooking oil to the skillet’s surface to prevent rust, and cover it with a paper towel or cloth to protect it from dust. This will help to keep your skillet in good condition, ensuring that it continues to perform well for years to come.
