To wash a seasoned cast-iron skillet and prevent rusting, follow these steps:
Allow the skillet to cool: After cooking, let the skillet cool down completely before cleaning it. Handling a hot skillet can cause burns or warping.
Avoid using soap: Soap can strip away the seasoning on the skillet, which is the protective layer that prevents rusting. Instead, rely on other methods to clean the skillet.
Use hot water and a brush or sponge: Rinse the skillet under hot water while gently scrubbing it with a brush or sponge. The hot water helps to loosen any stuck-on food particles.
Stubborn food residue: If there are stubborn food residues, create a paste by mixing coarse salt and a small amount of water. Scrub the affected area using this paste to help remove the residue.
Rinse and dry immediately: Thoroughly rinse the skillet to remove any remaining salt or food particles. Make sure to dry it immediately using a clean towel or by placing it on the stovetop over low heat for a few minutes. Drying is crucial to prevent rusting.
Apply a thin layer of oil: After washing and drying, apply a thin layer of cooking oil or a dedicated cast-iron seasoning oil to the skillet. This helps maintain the seasoning and prevents rusting. Use a cloth or paper towel to spread the oil evenly across the skillet's surface, including the handle.
Store properly: Store the cast-iron skillet in a dry place. If stacking it with other cookware, place a paper towel or a piece of cloth between the skillets to prevent them from scratching each other.
Remember, regular use and proper seasoning are key to maintaining the non-stick surface and preventing rust on your cast-iron skillet.
