No, it is not recommended to use dishwasher detergent on a cast iron skillet. Dishwasher detergents are typically designed for use on dishes and utensils made of materials like glass, ceramic, or stainless steel, but they can be too harsh for cast iron.
Cast iron requires special care to maintain its seasoning, which is a layer of polymerized oil that provides a non-stick surface. Dishwasher detergents are often alkaline and can strip away the seasoning, leading to rust and a loss of the skillet's non-stick properties.
To clean a cast iron skillet, it is generally recommended to follow these steps:
Hand wash: Clean the skillet with hot water and a gentle brush or sponge. Avoid using harsh scrub brushes or abrasive cleaners that can damage the seasoning.
Mild soap if necessary: If the skillet has stubborn food residues, you can use a small amount of mild dish soap. However, be cautious as using soap too frequently can still strip away the seasoning over time.
Rinse and dry thoroughly: Rinse the skillet thoroughly to remove any soap or food particles. Dry it completely to prevent rust. You can place it on a stovetop burner over low heat for a few minutes to evaporate any remaining moisture.
Apply a thin layer of oil: After cleaning and drying, apply a thin layer of oil to the skillet's surface to maintain or restore its seasoning. You can use vegetable oil, canola oil, or other oils with a high smoke point.
Remember, regular maintenance and proper seasoning are crucial for the care of cast iron cookware. If your skillet has stubborn residues or requires a deep clean, it's often recommended to use a specialized cast iron cleaner or follow specific cleaning techniques suitable for cast iron cookware.
