Black or Grey Marks on Dishes- Dishwasher

Possible Solutions

Are there black or gray marks on the dishes?

Aluminum items (such as utensils) should be loaded so that they will not rub against dishes during washing. Throw-away aluminum items should be hand-washed and not washed in the dishwasher because they may break down and cause marking. Aluminum markings can be removed by using a mild abrasive cleanser.
