1. Clean the skillet immediately after use, while it is still hot or warm. (Avoid soaking the pan or leaving it in the sink, or it may rust.) 2. Wash the skillet by hand using hot water and a sponge or stiff brush. (Avoid using the dishwasher, soap, or steel wool, as these may strip the pan's seasoning.) 3. To remove stuck-on food, scrub the pan with a paste of Kosher salt and water. Stubborn food residue may also be loosened by boiling water in the pan. 4. Thoroughly towel dry the skillet or dry it on the stove over low heat. 5. Using a cloth or paper towel, apply a light coat of vegetable oil or melted shortening to the inside of the skillet. Some people also like to coat the outside. 6. Store the skillet in a dry place.
