Washing a cast iron pan or wok with soap or detergent is generally safe and will not damage the seasoning, contrary to a common myth. Modern dish soaps and detergents are mild and unlikely to strip away the seasoning if used in moderation. However, it's still important to follow proper cleaning techniques to maintain the seasoning and prevent food from sticking more easily in the future.
Here's a recommended method for cleaning a cast iron pan or wok:
- After cooking, allow the pan to cool down slightly. Never submerge a hot cast iron pan in water as this can cause warping.
- Use warm water and a mild dish soap or detergent to clean the pan. Gently scrub the surface with a soft sponge or nylon brush to remove any food residue. Avoid using abrasive materials that can damage the seasoning.
- Rinse the pan thoroughly to remove all soap or detergent residue.
- Dry the pan completely using a clean towel or by placing it on a stovetop over low heat. Ensure that all moisture is evaporated to prevent rusting.
- Once dry, you can optionally apply a thin layer of cooking oil or a dedicated cast iron conditioner to the cooking surface to help maintain the seasoning. Use a paper towel to evenly distribute the oil and remove any excess.
- Store the pan in a dry place to prevent moisture buildup.
By following these steps, you can keep your cast iron pan or wok clean without compromising the seasoning. Regular maintenance and proper seasoning will help ensure a non-stick surface and optimal cooking performance.
