Cast iron skillets are not dishwasher-friendly, so they require a different approach compared to other cookware. Here are the steps to take when cleaning your cast-iron cookware: 1. After cooking, let the cast iron skillet cool down completely. 2. Use a stiff brush, scraper or spatula to remove any food or residue stuck to the skillet. Avoid using metal or abrasive materials that may damage the seasoning. 3. Rinse the skillet under hot water while gently scrubbing with a non-abrasive tool. Don't use soap, as it can strip away the skillet's seasoning. 4. Once rinsed, pat the skillet dry using a clean kitchen towel or paper towels to prevent rusting. 5. After drying, apply a thin layer of oil to the entire surface of the skillet to help maintain the skillet's seasoning and prevent rust. Then place a paper towel inside to absorb excess moisture. Store your cast iron in a dry place with good ventilation.
