InterDesign 255 00 Clean & Dirty Dishwasher Indicator
This simple device informs the family whether dishes in the dishwasher are clean or dirty. It adheres to the dishwasher with a suction cup. Half black (with a "dirty" sign) and half clear (with a "clean" sign), the 3-inch device can be spun to position the proper sign at the top so everyone knows what's what.--Fred Brack
