Wash silverware in hot, sudsy water, then rinse in clear, hot water. Clean crevices with a worn toothbrush or fine natural-bristle brush. To avoid spotting, immediately dry the pieces with a chamois or soft cotton cloth. Although silverware is considered dishwasher safe, hot temperatures can loosen hollow handles or dissolve a decorative, oxidized pattern. Keep detergent to a minimum and remove silverware from the dishwasher before the drying cycle.
