Dishwasher safe. Stainless steel cutlery needs a little extra care while dishwashing to avoid stains and marks: Avoid leaving cutlery unwashed ? rinse used cutlery immediately; Avoid soaking cutlery, avoid using steel wool or abrasive materials to clean cutlery; Separate cutlery steel and silverware in the dishwasher compartment to avoid permanent marks; After the dishwasher cycle is complete, remove and dry off any remaining water from the cutlery. This will avoid watermarking; Occasionally apply stainless steel polish to maintain lustre; Do not store in original packaging while not being used ? long-time exposure to humidity will escalate deterioration
