Title: How to beat the gray marks
Review: I like the simple design of Noritake Colorwave dishes, but was unhappy with gray marks from metal tableware. I have discovered that the right dishwasher detergent takes care of this. I was using a phosphate-free powder, for ecological reasons, but it was not getting my dishes clean. Researching this, I learned that in the last year, phosphate-free dishwasher detergents have improved a lot, so this problem may go away by itself. Otherwise, try a different phosphate-free detergent; the tablets seem to work best.
