When cleaning cast iron, it is generally recommended to use hot water. Hot water helps to loosen any stuck-on food or residue, making it easier to clean. However, it's essential to note that you should not leave cast iron to soak in water for extended periods, as prolonged exposure to water can lead to rusting.
Here's a step-by-step guide for cleaning cast iron with hot water:
Cool down the pan: After cooking, allow the cast iron pan to cool down slightly. It's not advisable to subject a hot cast iron pan to rapid temperature changes, as this can potentially damage it.
Rinse with hot water: Run hot water over the pan and use a soft brush or sponge to gently scrub off any food particles or residue. Be careful not to use any harsh abrasives, as they can strip away the seasoning (the protective layer that develops on cast iron with proper use and care).
Dry immediately: After washing, promptly dry the pan with a clean towel. Ensure it is completely dry, as any residual water left on the surface can lead to rusting.
Oil the pan: Once the cast iron pan is dry, apply a thin layer of oil (such as vegetable oil or flaxseed oil) to the surface. This helps to maintain the seasoning and protects the pan from rust.
It's worth noting that some people avoid using soap on their cast iron, as it can strip away the seasoning. If you opt to use soap, use a mild one and avoid harsh scrubbing. The seasoned surface of the cast iron helps to prevent food from sticking, so maintaining this layer is essential for optimal performance.
In summary, use hot water to clean cast iron, but be sure to dry and oil it afterward to prevent rusting and maintain the seasoning.
