Waiting until your pan has cooled down before washing it is important when using cast iron or carbon steel cookware for several reasons:
Prevents warping: Cast iron and carbon steel are sturdy materials, but they can still warp if exposed to extreme temperature changes. Rapidly cooling down a hot pan by running cold water on it can cause the metal to contract unevenly, leading to warping or even cracking of the cookware.
Avoids thermal shock: Introducing cold water to a hot pan can cause thermal shock, which can lead to the development of small cracks in the metal. Over time, these cracks can worsen and compromise the integrity of the pan.
Protects seasoning: Cast iron and carbon steel pans are often seasoned to create a natural non-stick surface. The seasoning is essentially a layer of polymerized oil that adheres to the metal. Rapid temperature changes or exposure to water when the pan is still hot can strip away this seasoning, reducing the non-stick properties and making the pan more susceptible to rusting.
Enhances longevity: Proper care and maintenance play a crucial role in extending the lifespan of cast iron and carbon steel cookware. Allowing the pan to cool down before washing it gently ensures that it retains its shape, seasoning, and overall quality for a longer time.
To clean cast iron and carbon steel cookware properly, follow these steps:
Let it cool down naturally: After cooking, remove the food from the pan and allow it to cool down on its own, away from direct heat or cold water.
Hand wash with minimal soap: Once the pan has cooled, wash it with warm water and a soft brush or sponge. Use minimal soap to avoid stripping away the seasoning.
Dry it thoroughly: After washing, dry the pan thoroughly with a clean towel to prevent any moisture from causing rust.
Apply a thin layer of oil: To maintain the seasoning and prevent rusting, lightly coat the pan with a thin layer of oil before storing it.
By following these practices, you can ensure the longevity and performance of your cast iron or carbon steel cookware and enjoy delicious meals for years to come.
