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.
Wire brush
The wire brush is primarily an abrasive implement, used for cleaning rust and removing paint. It is also used to clean surfaces and to create a better conductive area for attaching electrical connections, such as those between car battery posts and their connectors, should they accumulate a build-up of grime and dirt. When cleaning stainless steel, it is advisable to use a stainless steel bristle wire brush, as a plain carbon steel brush can contaminate the stainless steel and cause rust spots to appear. Brass bristle brushes are used on softer surfaces or when it is necessary to clean a harder surface without marring it. Brass bristle brushed are also used in potentially flammable environments where non-sparking tools are required. Wire brushes are also used to clean the teeth of large animals, such as crocodiles and pigs. They are also used widely in surface engineering to clean the castings to paint the castings.
