Cleaning a cast iron skillet without ruining its seasoning is essential to maintain its non-stick properties and prolong its lifespan. Follow these steps to clean your cast iron skillet properly:
Cool the skillet: Allow the cast iron skillet to cool down completely after cooking. Never attempt to clean it while it's still hot, as rapid temperature changes can damage the seasoning.
Avoid soap: Contrary to cleaning other cookware, you should avoid using soap on a cast iron skillet, especially if it's well-seasoned. Soap can strip away the seasoning and leave your skillet vulnerable to rust and a loss of non-stick properties.
Scrape off food residue: Using a non-metallic scraper or a wooden spatula, gently remove any food residue or stuck-on bits from the surface of the skillet. Avoid using metal utensils or harsh scraping tools, as they can damage the seasoning.
Rinse with water: Rinse the skillet under warm water while using a soft sponge or brush to clean off any remaining food particles. Use only water and avoid using any soap.
Salt scrub (if needed): If there are stubborn food residues or stains, create a paste by sprinkling coarse salt onto the skillet and adding a few drops of water. Use a non-metallic brush or sponge to scrub the surface gently.
Rinse and dry immediately: Once the skillet is clean, thoroughly rinse it with warm water to remove any remaining salt or debris. Dry the skillet completely using a clean towel or paper towels.
Heat to evaporate moisture: To ensure there is no moisture left on the skillet, place it on the stove over low heat for a few minutes. This step helps to evaporate any water left after rinsing.
Apply a thin layer of oil: Once the skillet is dry and still warm, apply a thin layer of cooking oil (vegetable oil, flaxseed oil, or grapeseed oil) to the entire surface, including the handle. You can use a paper towel or a cloth to apply the oil evenly.
Buff the skillet: Using a fresh paper towel or cloth, gently buff the skillet to remove any excess oil. The skillet should appear slightly shiny but not oily.
By following these steps, you can clean your cast iron skillet effectively without compromising its seasoning. Regularly maintaining your skillet this way will help keep its non-stick properties intact and ensure it serves you well for years to come.
