Black or Grey Marks on Dishes - Portable 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 while washing. The movement of these items while washing transfers black marks to dishes and other items. The black and Grey markings can be removed by using a mild abrasive cleanser.
