How To Season Rusty Cast Iron Skillet?

Cast iron skillets are a timeless kitchen staple, known for their durability and versatility. 

However, if your skillet has become rusty, it’s important to restore it properly to maintain its effectiveness. 

Rust occurs when the iron in your skillet reacts with moisture and oxygen, leading to oxidation. 

Though it may seem like a daunting task, removing rust and re-seasoning a cast iron skillet is simpler than you might think. 

Allow me to share with you the right cleaning methods, so you can breathe new life into your rusty skillet. 

Get ready to transform it into a sleek, well-seasoned cooking tool that’s perfect for everyday use.

Why Does Cast Iron Rust?

Cast iron is a highly durable material, but it is prone to rust when exposed to moisture. 

The primary reason for this is the high iron (Fe) content in cast iron. This can easily oxidize and form rust when it comes into contact with air and water. 

Rust can affect your cookware’s cooking surface and may even cause food to stick to the pan.

To prevent rust from forming on your cast iron skillet, it is essential to properly clean and season it regularly.

Seasoning a rusty cast iron skillet revitalizes the non-stick surface, making it ready for your next culinary masterpiece.

How to Remove Rust and Season a Rusty Cast Iron Skillet

Here is how you can remove the rust and season a rusty cast iron skillet

Scrub and Wash Your Skillet

To remove rust from your cast iron skillet, begin by scouring the rusty areas with steel wool or a Lodge Rust Eraser

Wash your skillet with warm, soapy water to remove any debris. 

Keep in mind that you may strip off some seasoning during this process but don’t worry, as you’ll be re-seasoning the skillet later.

Apply Oil

After cleaning the rust, pat your skillet dry with a paper towel or lint-free cloth. 

Then, apply a thin layer of vegetable oil or your preferred oil to the entire surface of the skillet, including the exterior. 

The best oil would be any neutral oil like grapeseed, canola, flaxseed, or any vegetable oil blend.

Don’t use a lot of oil, a tablespoon or two should be enough to coat the entire skillet.

The oil helps create a protective barrier and non-stick surface, ensuring your skillet’s longevity.

Oven Method

One way to season your cast iron skillet is the oven method. Preheat your oven to 400°F (205°C). 

Place a sheet of aluminum foil on the bottom rack to catch any excess oil that may drip off the skillet. 

Place the oiled skillet upside down onto the top rack and bake it for one hour. Once the hour is up, turn off the oven and let the skillet cool inside. 

This method helps bake the oil into the skillet, creating a durable, non-stick surface. It will also help to sterilize an old cast iron skillet.

Stovetop Method

An alternative to the oven method is the stovetop method. Heat the oiled skillet over medium heat on the stovetop until it starts to smoke slightly. 

Keep the heat on for a few more minutes, allowing the oil to burn into the skillet and create a non-stick surface. 

Once you’ve done this for a few minutes, turn off the heat and let the skillet cool down before using it. 

Remember to always dry your skillet thoroughly after cleaning it to prevent future rust buildup and maintain the seasoning on the surface.

How to Clean the Rusty Cast Iron Skillet Without Soap

If you have a rusty cast iron skillet, don’t worry, it’s not the end of the world. You can restore it to its original condition without the use of soap. 

First, grab a potato, some vinegar, and coarse salt to help clean the surface. 

Cut a potato in half and sprinkle the coarse salt over the skillet’s rusty areas. Next, dip the cut side of the potato into the vinegar. 

Using the potato as a scouring pad, scrub the salt and vinegar over the rusted surface. The coarse salt acts as an abrasive, while the vinegar helps to dissolve the rust. 

Repeat this process until all the rust is removed from your skillet.

Once the rust is gone, rinse the skillet with water to remove any remaining salt and vinegar residue. 

Ward off any additional rust by thoroughly drying the skillet, either by using a towel or placing it in a warm oven for a few minutes.

You can also use baking soda and vinegar paste to scrub away the rust. Watch how to do it here:

How to Care for a Cast Iron Skillet and Prevent Rusting

Caring for your cast iron skillet is essential to maintain its nonstick surface, prevent rusting, and ensure a long-lasting cooking performance. 

One of the first things you should do is properly season your skillet, which involves baking a thin layer of oil into the surface.

In addition to seasoning, regular and diligent cleaning is necessary to maintain your skillet. After each use, wash your skillet with water and minimal soap if needed. 

Remember to avoid abrasive metal scrubs; instead, use the firm side of a sponge. 

Avoid placing it in the dishwasher as the constant presence of water can cause the cast iron to form rust.

Once you have cleaned your skillet, dry it thoroughly with a towel to remove excess water droplets, which could cause rust over time.

Another important aspect of cast iron skillet care is how you store it. 

Make sure your skillet is completely dry and seasoned before storing it away. If you can, store your cast iron skillet in a dry and cool location.
