Washing a cast iron skillet after every use is a matter of personal preference and depends on how you prefer to maintain your skillet. Some cast iron enthusiasts advocate for minimal washing, while others prefer a more thorough cleaning. Here are a few different approaches to consider:
Minimal washing: Many cast iron enthusiasts prefer to minimize washing and instead rely on the "seasoning" process to maintain the skillet's non-stick surface and prevent rusting. With this approach, after cooking, you can simply wipe the skillet clean with a paper towel or a soft cloth to remove any food residue. If necessary, you can add a small amount of mild detergent-free soap and gently scrub with a soft brush or sponge. Rinse the skillet with water, dry it thoroughly with a towel, and then apply a thin layer of oil to protect the seasoning. This method helps preserve the seasoned surface and builds up the skillet's natural non-stick properties over time.
Moderate washing: If you prefer a slightly more thorough cleaning, you can wash your cast iron skillet with mild dish soap and water after each use. Use a soft brush or sponge to scrub away any food residue, rinse it well, and dry it thoroughly. After washing, it's still important to apply a thin layer of oil to the skillet to protect it from moisture and prevent rusting.
Intensive cleaning: In some cases, your cast iron skillet may require more extensive cleaning, such as when there are stubborn food residues, stuck-on particles, or if the skillet has become rusted. In such situations, you can use a mild abrasive, like kosher salt or a paste made from baking soda and water, to gently scrub the surface. Rinse it thoroughly, dry it completely, and reapply oil to restore the seasoning.
Remember that regardless of the cleaning method you choose, it's crucial to dry the skillet thoroughly to prevent rusting. Moisture is the enemy of cast iron, so ensure the skillet is completely dry before storing it.
Ultimately, the decision of how frequently to wash your cast iron skillet depends on your cooking habits, personal preferences, and the condition of the skillet. It's important to find a cleaning routine that works for you while ensuring the skillet remains well-maintained and protected.
