Product review (5 stars): Clean/Dirty Magnet for the Dishwasher
Years ago my mother in law gave me one for our dishwasher.  When that one no longer ran we replaced it with a new dishwasher.  I have looked all over in stores and never found one. Amazon has almost everything!!!  This is a helpful little product that saves you wondering if you need to put them away or run the washer.  Just remember to switch it to clean or dirty when you are done unloading it.
