Cleaning and maintaining a cast iron pan or wok after seasoning is essential to preserve its seasoning and extend its lifespan. Here's how to do it:
Cleaning:
Immediate Cleaning: Ideally, clean your cast iron pan or wok shortly after use. Avoid letting it sit with food residues, especially acidic or salty foods, as they can degrade the seasoning.
Cool Down: Allow the cast iron pan to cool down slightly before cleaning. While it should not be cold, it should also not be scorching hot to prevent thermal shock.
Gentle Scrubbing: Use a soft brush or sponge and hot water to gently scrub the surface. Avoid using harsh abrasives or metal scouring pads that could remove the seasoning.
No Soap: It's generally recommended to avoid using soap as it can strip away the seasoning. Hot water and scrubbing should be sufficient for most cleaning tasks.
Stubborn Residues: If you have stubborn residues that won't come off with water alone, add some coarse salt to the pan and use it as a mild abrasive. This helps lift off any stuck-on food without damaging the seasoning.
Rinse and Dry Thoroughly: Rinse the pan thoroughly with hot water to remove any remaining food particles. After washing, dry the pan completely using a towel or by placing it on the stovetop over low heat for a few minutes.
Maintaining:
Oil After Each Use: To maintain the seasoning and prevent rusting, lightly coat the cooking surface with a thin layer of oil after each use. Use a paper towel or cloth to spread the oil evenly. This helps replenish the protective layer.
Avoid Moisture: Prevent moisture from coming into contact with the cast iron as much as possible. Dry the pan thoroughly after washing, and avoid leaving liquids or damp food in the pan for extended periods.
Store Properly: Store the cast iron pan in a dry place. If you stack other pans on top of it, place a paper towel or cloth between them to prevent moisture accumulation.
Re-seasoning: Over time, the seasoning may wear off due to regular use. If you notice the surface becoming less non-stick or prone to rust, consider re-seasoning the pan. Follow the seasoning process mentioned earlier to restore its performance.
Remember that the more you use your cast iron pan, the better the seasoning will become, leading to a naturally non-stick surface. Properly maintained cast iron cookware can last for generations and provide you with excellent cooking results for many years to come.
