Yes, you can wash a cast iron skillet with dish soap, but it's important to do so with some caution and care. Traditionally, cast iron enthusiasts have been advised to avoid using soap to prevent stripping away the seasoning, a protective layer of oil that builds up over time and provides a natural non-stick surface. However, modern cast iron skillets are more resilient and can handle occasional use of dish soap without significant damage.
Here are some tips for washing a cast iron skillet with dish soap:
Use a mild dish soap: If you choose to use dish soap, opt for a mild, gentle one. Avoid harsh chemicals and heavy-duty detergents that can be too aggressive on the cast iron surface.
Rinse immediately: After cooking, rinse the skillet with hot water immediately. This helps to remove any food residues and makes the cleaning process easier.
Scrub gently: Use a soft sponge or brush to gently scrub the surface. Avoid using steel wool, metal scrubbers, or abrasive cleaning tools that could damage the seasoning.
Don't soak: Avoid soaking the cast iron skillet in soapy water for extended periods. Brief contact with soap is sufficient to clean it.
Dry thoroughly: After washing, dry the skillet thoroughly with a towel to prevent moisture from causing rust.
Re-season if necessary: If you notice that the seasoning has been affected after using dish soap, you can always re-season the skillet to restore its protective coating.
Remember that while using dish soap occasionally is generally safe for modern cast iron skillets, it's still a good idea to minimize its use. For day-to-day cleaning, a simple rinse with hot water and gentle scrubbing using a brush or sponge is often sufficient. This way, you can preserve and maintain the seasoning, ensuring your cast iron skillet remains in excellent cooking condition.
