How to clean cast iron pans to make them last for decades

To clean cast iron pans and prevent rust, avoid harsh soaps and abrasive cleaners. Instead, use coarse salt as a gentle scrub to remove food residue while preserving the pan's non-stick properties. After cooking, wash the pan while still warm with hot water and a wooden spoon or soft brush. For stubborn residue, use coarse salt. Always dry the pan thoroughly, preferably on the stovetop over low heat, to prevent rust. Never put cast iron in a dishwasher, as it will strip the protective seasoning. For light cleaning, a damp cloth is often sufficient. Proper care ensures cast iron pans can last for decades.
