Care of Your Aluminum Serveware: Each piece is individually crafted and polished by hand. Flawless perfection can only be achieved on an assembly line, and is not our intention. Variations in the product reinforce the fact that every piece is made by hand, and therefore is unique. Wash your Arthur Court Designs aluminum serveware by hand with mild dishwashing soap and dry immediately. DO NOT WASH IN DISHWASHER. The brilliant polished luster of your aluminum will be permanently dulled by the high heat of a dishwasher or oven.
