Cast iron skillets have been a staple in many kitchens for centuries, and with good reason. They are incredibly durable, versatile, and can distribute heat evenly, making them ideal for a wide range of cooking techniques. However, over time, these skillets can accumulate a thick layer of grime, food residue, and rust, making them look and perform poorly. If you’re struggling with an old dirty cast iron skillet, don’t worry – with the right techniques and cleaning solutions, you can restore it to its former glory.
Before You Start: Preparing Your Skillet for Cleaning
Before you begin cleaning your cast iron skillet, it’s essential to prepare it properly. This involves removing any loose food particles and debris that may be stuck to the surface. Start by scraping off any large chunks of food using a soft brush or a non-abrasive scraper. Be gentle, as you don’t want to scratch the surface of the skillet.
Next, mix 1 tablespoon of kosher salt with 1 tablespoon of water to form a paste. Apply the paste to the skillet and let it sit for about 30 minutes. The salt will help loosen any tough grime and food residue. After 30 minutes, use a soft brush or sponge to wipe away the paste and any debris that has been loosened.
Choosing the Right Cleaning Solution
When it comes to cleaning a cast iron skillet, you’ll want to use a gentle cleaning solution that won’t strip away the seasoning. Seasoning is a layer of oil that is baked onto the surface of the skillet, creating a non-stick surface. Avoid using harsh chemicals, abrasive cleaners, or scouring pads, as these can damage the seasoning and strip away the non-stick properties.
Instead, opt for a mild cleaning solution, such as:
- Warm water and a soft sponge
- A mixture of equal parts water and white vinegar
- A gentle dish soap, such as diluted Seventh Generation or Dawn
What to Avoid
When cleaning your cast iron skillet, there are several things you should avoid:
- Never put your cast iron skillet in the dishwasher. The high heat and harsh detergents can damage the seasoning and strip away the non-stick properties.
- Avoid using abrasive cleaners or scouring pads. These can scratch the surface of the skillet and damage the seasoning.
- Don’t use bleach or harsh chemicals. These can damage the seasoning and strip away the non-stick properties.
Deep Cleaning Your Cast Iron Skillet
If your cast iron skillet has a thick layer of grime or rust, you may need to use a more aggressive cleaning solution. In this case, you can try using a mixture of equal parts water and white vinegar, or a gentle dish soap.
To deep clean your cast iron skillet, follow these steps:
- Apply the cleaning solution to the skillet and let it sit for about 30 minutes. This will help loosen any tough grime and food residue.
- Use a soft brush or sponge to scrub away any debris and grime. Be gentle, as you don’t want to scratch the surface of the skillet.
- Rinse the skillet thoroughly with warm water to remove any remaining cleaning solution and debris.
- Dry the skillet with a towel and apply a thin layer of oil to the surface. This will help restore the seasoning and prevent rust.
Removing Rust from Your Cast Iron Skillet
If your cast iron skillet has developed rust, you’ll need to remove it before you can restore the seasoning. To remove rust, follow these steps:
- Mix 1 tablespoon of baking soda with 1 tablespoon of water to form a paste. Apply the paste to the rusty area and let it sit for about 30 minutes.
- Use a soft brush or sponge to scrub away the rust. Be gentle, as you don’t want to scratch the surface of the skillet.
- Rinse the skillet thoroughly with warm water to remove any remaining baking soda and rust.
- Dry the skillet with a towel and apply a thin layer of oil to the surface. This will help restore the seasoning and prevent further rust.
Preventing Rust in the Future

Re-Seasoning Your Cast Iron Skillet
Once you’ve cleaned and removed any rust from your cast iron skillet, you’ll need to re-season it. Re-seasoning involves applying a layer of oil to the surface of the skillet and baking it in the oven to create a non-stick surface.
To re-season your cast iron skillet, follow these steps:
- Apply a thin layer of oil to the surface of the skillet. You can use any type of oil, such as vegetable oil or peanut oil.
- Place the skillet in the oven at 350°F (175°C) for about an hour. This will help the oil penetrate the surface of the skillet and create a non-stick surface.
- Let the skillet cool before wiping off any excess oil with a paper towel.
