Clean a cast-iron pan by adding hot water and soap to the pan, then scrubbing gently with a stiff brush. After a few minutes, wash the pan under hot water, and towel it dry immediately. Apply a small amount of oil to the surface to prevent rust.
- Add hot water and soap to the pan
Pour hot water into the pan to cover the bottom inch or so. Add a quarter of a teaspoon of mild dishwashing soap. Mix the soap into the hot water and wait five minutes.
- Scrub the pan
Use a stiff brush to gently remove any stuck-on food or grease from the cast-iron pan. Use a steel wool pad if there is rust or blackened food in the pan. Scrub the pan using circular motions. Pour out the soapy water and check if there is any burned food left. Add hot soapy water again if necessary.
- Towel-dry the pan
Place a towel on your kitchen counter. Put the pan on it, and dry the sides and the inside of the pan. Make sure the pan is completely dry.
- Apply oil to the pan
Pour a tablespoon of cooking oil into the pan. Use a kitchen towel to wipe the inside and the outside of the pan with the cooking oil. Store the pan upside down to keep the inside clean during storage.
