Cast-iron cookware
Because other cookware cleaning techniques like scouring or washing in a dishwasher can remove or damage the seasoning on a bare cast-iron pan, these pans should not be cleaned like most other cookware. Some chefs advocate never cleaning cast-iron pans at all; simply wiping them out after use, or washing them with hot water and a stiff brush. Others advocate washing with mild soap and water, and then re-applying a thin layer of fat or oil. A third approach is to scrub with coarse salt and a paper towel or clean rag.
Dishwashing
Dish washing is usually done using an implement for the washer to wield, unless done using an automated dishwasher. Commonly used implements include cloths, sponges, brushes or even steel wool. As fingernails are often more effective than soft implements like cloths at dislodging hard particles, washing simply with the hands is also done and can be effective as well. Dishwashing detergent is also generally used, but bar soap can be used acceptably, as well. Rubber gloves are often worn when washing dishes by people who are sensitive to hot water or dish-washing liquids. According to dermatologists, the use of protective gloves is highly recommended whenever working with water and cleaning products, since some chemicals may damage the skin, or allergies may develop in some individuals. Dish gloves are also worn by those who simply don't want to touch the old food particles. Many people also wear aprons.
