To clean your precious skillet, you will need the following tools and materials:

  1. A dishtowel or paper towel
  2. thong and sponge, cast iron brush, or wooden spoon and Kosher salt
  3.  dishwashing liquid (optional)
  4. cooking oil or any unsaturated fat

If there are stubborn bits of food on the surface, cleaning with hot water right after cooking is fine.

Most modern dishwashing liquid will not harm your cast iron skillet surface but watch out for lye-based soap. You can use a sponge and a thong to scrub your cast iron surface to avoid your hand’s contact with hot water.

A convenient option is using a cast iron brush or scraper. DON’T use a metal brush. You can also add kosher salt and use a wooded spoon to brush off the stuck-on foods.

It is up to you which method you prefer. It will most likely depend on the tools you have available in your home.

Rinse off and dry thoroughly with a dishtowel or paper towel. Please, DON’T ever soak your cast iron skillet in water for hours.

Step Four

Season the skillet with cooking oil or any saturated fat using a cloth or paper towel and store it in a cool dry place after seasoning.

Putting a piece of paper in between your pans may also help protect your cast iron skillet surface.
