Using soap on a cast iron skillet is a debated topic among cooking enthusiasts. Traditionally, it has been advised to avoid using soap on cast iron cookware due to concerns that it may strip away the seasoning layer—a natural coating of polymerized oil that gives the skillet its non-stick properties and protects it from rust.
However, the truth is that using a small amount of mild soap on your cast iron skillet is generally safe and won't ruin the seasoning if done correctly. Here are some guidelines to follow:
Use mild soap: If you decide to use soap, make sure it's a mild dish soap. Harsh detergents and heavy chemicals may damage the seasoning.
Don't soak the skillet: Avoid soaking the cast iron skillet in water for extended periods, as this can lead to rust formation. Instead, clean it promptly after use.
Use a soft brush or sponge: Scrub the skillet gently with a soft-bristled brush or sponge. Avoid using abrasive scouring pads, which can damage the seasoning.
Rinse and dry immediately: After washing with soap, rinse the skillet thoroughly to remove any soap residue. Then, dry it completely with a towel.
Re-season if necessary: If you notice any loss of seasoning or if the skillet becomes dull, you can reapply a thin layer of oil and bake it in the oven to maintain its non-stick properties.
Be consistent: If you decide to use soap, it's best to use it every time you wash the skillet. Consistency helps maintain the seasoning and prevents any potential issues with soap residue.
Alternatively, if you prefer to avoid using soap altogether, you can use a technique called "deglazing" to clean your cast iron skillet. Deglazing involves using water and a spatula to release food particles stuck to the pan's surface while preserving the seasoning. After deglazing, rinse the skillet, dry it thoroughly, and apply a thin layer of oil to protect it.
Ultimately, the decision to use soap or not on your cast iron skillet comes down to personal preference. If you're diligent in your cleaning and maintenance, using a little soap occasionally shouldn't cause any problems, and it can help ensure your skillet stays clean and safe for cooking.
