You love your cast iron skillet. It’s a seasoned veteran in your kitchen, producing crispy edges and perfectly browned meats. But recently, you’ve noticed something unsettling – rust. That familiar, dark, smooth surface is now marred by reddish-brown blemishes. Don’t despair! Learning how to clean a cast iron skillet that has rust is easier than you think, and with a little elbow grease, you can restore your beloved pan to its former glory.
The Science Behind Cast Iron Rust
Before we dive into the cleaning process, let’s understand why cast iron rusts. Cast iron is a porous material, and when exposed to moisture, it reacts with oxygen to form iron oxide, commonly known as rust. While a light layer of rust is normal, especially if your skillet isn’t seasoned properly, excessive rust can affect its performance and even make it unsafe to use.
Assessing the Damage: How Much Rust Are We Dealing With?
The first step is to assess the severity of the rust. Is it a light surface rust, or is it deeply embedded and pitting the surface? For light rust, a simple cleaning method might suffice. For heavier rust, you might need a more aggressive approach.
Cleaning Methods for Light Rust
1. The Salt and Oil Method
This method is ideal for light rust and involves using the abrasive properties of salt to scrub away the rust.
1. Heat the skillet: Place the skillet over medium heat on your stovetop.
2. Add salt: Sprinkle a generous amount of coarse salt onto the hot skillet.
3. Scrub with a crumpled paper towel: Use a crumpled paper towel or a clean, dry cloth to scrub the salt into the rust.
4. Wipe clean: Once the salt has cooled, discard it and wipe the skillet clean with a fresh paper towel.
5. Season the skillet: Apply a thin layer of cooking oil to the entire surface of the skillet and heat it over low heat for a few minutes. This will help re-season the skillet and protect it from future rust.
2. The Baking Soda Paste Method
Baking soda is a gentle abrasive that can effectively remove light rust.
1. Make a paste: Combine baking soda with a small amount of water to create a thick paste.
2. Apply the paste: Spread the paste evenly over the rusted areas.
3. Scrub gently: Use a non-abrasive sponge or a soft cloth to scrub the paste into the rust.
4. Rinse and dry: Rinse the skillet thoroughly with warm water and dry it completely.
5. Season the skillet: Apply a thin layer of cooking oil to the entire surface of the skillet and heat it over low heat for a few minutes.
Cleaning Methods for Heavy Rust
1. The Vinegar Soak
Vinegar is a natural acid that can help dissolve rust.
1. Soak the skillet: Fill a large pot or container with white vinegar and submerge the rusty skillet completely.
2. Soak for several hours or overnight: Let the skillet soak for at least several hours, or even overnight, for best results.
3. Scrub with a wire brush: After soaking, use a wire brush to scrub away any remaining rust.
4. Rinse and dry: Rinse the skillet thoroughly with warm water and dry it completely.
5. Season the skillet: Apply a thin layer of cooking oil to the entire surface of the skillet and heat it over low heat for a few minutes.
2. The Cast Iron Cleaner
Several commercial cast iron cleaners are available that can effectively remove rust. Follow the manufacturer’s instructions carefully.
Prevention is Key: How to Keep Your Cast Iron Rust-Free
Once you’ve successfully cleaned your rusty skillet, it’s important to take steps to prevent future rust formation.
- Dry thoroughly: After each use, wash your skillet with hot soapy water and dry it completely. Even a tiny bit of moisture can lead to rust.
- Season regularly: A good layer of seasoning acts as a protective barrier against rust. Apply a thin layer of cooking oil to the entire surface of the skillet after each use and heat it over low heat for a few minutes.
- Store properly: Store your skillet in a dry place, preferably with a layer of oil applied to the surface.
