Cast-iron cookware is renowned for its durability. However, you must take proper care of it to maintain its longevity. Whether you’ve just purchased a new pot, pan or casserole dish, follow these expert tips to keep it in top shape.

• Give it a deep clean. Start by cleaning the cookware with hot water, mild soap and a soft-bristled brush. Rinse thoroughly and dry with a clean cloth.

• Cover it with oil. Use a lint-free cloth to apply a thin layer of neutral oil to the entire surface of the cookware. Choose an oil with a high smoke point, such as canola oil.

• Heat the cookware in the oven. Preheat your oven to 205C. Place the cast-iron dish upside down on the middle rack, with a baking sheet underneath to catch any oil. Heat for 30 to 45 minutes, then turn off the oven and let the cookware cool inside.

• Repeat the process. Repeat the two previous steps twice to ensure the oil fully coats the roughness of the cast iron, giving it a smooth, non-stick surface.

For best results, repeat this process on your cast-iron cookware once or twice a year.

You don’t have to go overboard for everyday cleaning. Use hot water – taking care to avoid soaking the cookware – and, if necessary, coarse salt to scrub away any sticky particles. Once dry, apply a thin layer of oil. That’s it. Your prized cookware is ready to be stowed away until its next use.
