Modern homes have appliances with stainless-steel fronts, stainless pots for cooking, a stainless sink and usually stainless flatware for the table. Stainless is the metal of choice for commercial food equipment as well. Stainless has proven to be durable and attractive for years, but it takes some cleaning, particularly pieces that have been in contact with food. A soap-and-water wash does not clean the stains on stainless. You can keep stainless shiny with proven cleaning solutions.
Use white vinegar for cleaning stainless, whether cleaning the sink or a stainless pot that has cooked beans. This is the cleaner recommended by the University of Arkansas Extension Service. Place the vinegar on a sponge or soft cloth and rub the stainless. Wash with detergent and water and rinse clean. White vinegar is also the solution suggested by Vassar College.
