How To Restore Cast Iron

Cast iron is a durable and versatile material that has been used in cookware for centuries. However, if not properly cared for, it can become rusty and worn. In this article, we will discuss how to restore cast iron to its former glory.


Before you can restore your cast iron, you need to clean it thoroughly. Start by washing the cast iron with hot soapy water. Use a stiff brush or scrubber to remove any rust or food residue. Rinse the cast iron thoroughly and dry it completely with a towel.

Removing Rust

If your cast iron has rust spots, you will need to remove them before restoring it. There are several methods for removing rust from cast iron. One option is to use a mixture of equal parts white vinegar and water. Soak the cast iron in the mixture for several hours, then scrub with a stiff brush. Rinse and dry thoroughly.


Once your cast iron is clean and free of rust, it’s time to season it. Seasoning helps to create a non-stick surface and protect the cast iron from rust. To season your cast iron, preheat your oven to 350 degrees Fahrenheit. Rub a thin layer of vegetable oil or melted shortening over the entire surface of the cast iron, including the handles. Place the cast iron in the oven and bake for one hour. Turn off the oven and let the cast iron cool completely before removing it.
