Regular Cleaning Methods
Washing with Hot Water and Minimal Soap
When it comes to cleaning your cast iron cookware, using hot water and minimal soap is key. Hot water helps to remove any food residue or oil buildup from the surface of the cookware. Be careful not to use excessive amounts of soap, as this can strip the seasoning from the cast iron. Instead, use a small amount of mild dish soap and a soft sponge or brush to gently scrub the cookware. Rinse it thoroughly with hot water and make sure to dry it completely to prevent any moisture from lingering and causing rust.
Using Salt Scrub
To tackle tougher food residue or stubborn stains on your cast iron cookware, using a salt scrub can be very effective. Simply sprinkle a generous amount of coarse salt onto the surface of the cookware and use a damp sponge or cloth to scrub it in a circular motion. The salt helps to naturally scour away any remnants while also adding some mild abrasion to remove stains. Once you’ve scrubbed the cookware thoroughly, rinse it with hot water and dry it completely.
Seasoning with Oil
One of the most important aspects of caring for your cast iron cookware is regularly seasoning it with oil. Seasoning creates a protective layer on the surface of the cookware, preventing moisture from coming into direct contact with the iron and causing rust. To season your cookware, start by applying a thin layer of oil (such as vegetable oil or flaxseed oil) to the entire surface, including the handle. Make sure to rub the oil in evenly, and then use a clean cloth to remove any excess. Place the cookware upside down in an oven that has been preheated to around 350°F (175°C) for about an hour. This allows the oil to polymerize, creating a durable, non-stick coating.
Avoiding Soaking in Water
While it may be tempting to simply soak your cast iron cookware after use, this is actually one of the worst things you can do for its longevity. Soaking exposes the iron to prolonged moisture, which can lead to rust formation. Instead, opt for hand-washing with hot water and minimal soap, as mentioned earlier. If there are any stubborn food particles, use a salt scrub or a nylon brush to gently clean the surface. Avoid using metal scrubbers or abrasives, as these can remove the seasoning and potentially damage the cookware.
Drying Thoroughly
After cleaning your cast iron cookware, it is crucial to dry it thoroughly to prevent any moisture from causing rust. Use a clean towel or paper towels to carefully dry the entire surface, including the handle and bottom. Inspect the cookware to make sure there are no damp spots or lingering moisture.
