Can you tell I'm gearing up for Thanksgiving? OK, a few years ago I scored a set of Noritake china. I have used it exactly ONCE. So, I have to wash all the pieces again before serving dinner and then after dinner of course. But, can I use a dishwasher? If I do, do I need a special detergent or something? These are plain white with a simply silver Greek key edging. They are from the 1950s and never used before I got them. I plan to use them 1-2 times a year.
