Cleaning a pre-seasoned cast iron pan without removing the seasoning requires some special attention to avoid damaging the protective layer. Here's a step-by-step guide on how to clean your pre-seasoned cast iron skillet effectively:
Cool the pan: Allow the cast iron pan to cool down completely after cooking. Avoid placing a hot pan under cold running water, as this sudden temperature change can cause it to warp or crack.
Use hot water and a soft brush or sponge: Rinse the pan with hot water to loosen any food particles or residue. Use a soft brush or sponge to gently scrub the surface. Avoid using abrasive scrubbers or harsh detergents that can strip away the seasoning.
Avoid soap: While some cast iron enthusiasts argue that a small amount of mild soap is acceptable, it's generally safer to skip soap altogether, especially with pre-seasoned pans. Soap can break down the seasoning, and it's unnecessary for most cleaning situations.
Salt scrub (if needed): For stubborn, stuck-on food, you can create a salt scrub. Sprinkle coarse kosher salt or table salt into the pan, and then use a damp cloth or paper towel to scrub the surface. The salt acts as a gentle abrasive to help remove stuck-on bits without damaging the seasoning.
Rinse and dry thoroughly: Once the pan is clean, rinse it thoroughly with hot water to remove any remaining salt or debris. Wipe the skillet dry using a clean towel.
Heat the pan: To ensure the pan is completely dry and to prevent any moisture-related issues, place it on the stove over low heat for a few minutes. This step helps evaporate any remaining moisture.
Apply a thin layer of oil: After the pan has cooled down slightly but is still warm, apply a thin layer of cooking oil (such as vegetable oil, flaxseed oil, or grapeseed oil) to the entire surface of the pan, including the outside. Use a paper towel or cloth to spread the oil evenly.
Remove excess oil: Using a clean paper towel, gently wipe away any excess oil. The layer of oil should be thin; otherwise, it can become sticky or rancid over time.
Store properly: Store the cast iron pan in a dry place to prevent moisture from affecting the seasoning.
Remember, the more you use your pre-seasoned cast iron skillet, the better its seasoning will become. Over time, with regular use and proper care, the pan will develop a naturally non-stick surface, making it a reliable and long-lasting kitchen tool.
