It is not recommended to put cold water in a hot cast iron skillet. Sudden temperature changes can cause thermal shock, which can potentially damage the cast iron or lead to warping. Cast iron is known for its excellent heat retention, so it's best to allow it to cool naturally before adding water.
To clean a cast iron skillet, it's generally advised to follow these steps:
Allow the pan to cool: After cooking, let the cast iron skillet cool down on the stovetop or a heat-resistant surface. This helps prevent any potential damage from thermal shock.
Rinse with warm water: Once the pan has cooled, rinse it with warm water to remove any food residue. Avoid using soap, as it can strip away the seasoning. Instead, use a gentle brush or sponge to scrub off any stuck-on bits.
Dry thoroughly: After rinsing, thoroughly dry the cast iron skillet to prevent rust formation. Use a kitchen towel or paper towel to remove all moisture from the surface.
Oil the skillet: To further protect the cast iron and maintain its seasoning, lightly oil the skillet while it's still warm. Apply a thin layer of cooking oil or a dedicated cast iron conditioner to the cooking surface and rub it in with a paper towel or cloth. This helps to create a protective barrier against rust.
By allowing the skillet to cool naturally before cleaning and ensuring it is completely dry after washing, you can minimize the risk of rust formation. However, it's important to note that cast iron cookware requires ongoing maintenance to keep it in optimal condition. Regularly seasoning and properly storing the skillet are essential practices for preventing rust and maintaining its performance.
