Cleaning cast-iron cookware after cooking with oil or ghee requires some specific care to maintain its seasoning and prevent rusting. Here's the best way to clean cast-iron cookware:
Wait for it to cool down: Allow the cast-iron cookware to cool down slightly after cooking. Cleaning it while it's still hot can damage the seasoning or cause warping.
Use hot water and a sponge/brush: Rinse the cookware under hot running water. Use a soft sponge or a brush to gently scrub off any food particles or residue. Avoid using harsh abrasive materials or metal scouring pads, as they can strip away the seasoning.
Avoid soap: It's generally best to avoid using soap when cleaning cast iron, especially if it's well-seasoned. Soap can break down the seasoning, which is the natural non-stick layer that develops on the surface of cast iron over time. If there are stubborn food residues, you can add a small amount of mild dish soap, but make sure to rinse thoroughly.
Salt scrub: For tough-to-clean spots, you can sprinkle some coarse salt on the cookware and use a damp cloth or paper towel to create a gentle abrasive scrub. The salt helps lift off stuck-on food without damaging the seasoning.
Rinse and dry thoroughly: After cleaning, rinse the cookware thoroughly to remove any remaining salt or debris. Then, pat it dry with a clean towel or paper towel.
Oil it up: To maintain the seasoning and prevent rust, it's essential to oil the cast iron after cleaning. While the cookware is still warm (but not hot), apply a thin layer of cooking oil or melted shortening to the entire surface, including the handle. You can use a paper towel or a cloth for this. Be sure to wipe off any excess oil.
Store it properly: Store the cast iron in a dry place to prevent moisture from causing rust. If you stack your cast-iron cookware, place a paper towel or cloth between the pieces to avoid any potential scratching or damage to the seasoning.
By following these steps, you can clean your cast-iron cookware effectively while preserving its seasoning and ensuring it remains a reliable and long-lasting kitchen tool.
