My friend, Lena, suggested that I try using some Calgon in the dishwasher. She said that they use a powdered Calgon at her school (she teaches at a Montessori school), and they just throw some in the bottom of the dishwasher every time they do the dishes. Well, I happened to have some liquid Calgon sitting in my basement from our apartment days (Yep. I never threw it out). So, I gave that a whirl. (I only threw half a capful down in the bottom of the dishwasher.)
WOOOHOOO! Ancient Chinese secret, huh?
