The next time you really have NOTHING to do, and I mean NOTHING TO DO, here is an idea. Get a GoPro and stick it inside the dishwasher with the dinner plates, glasses, utensils, etc and turn it on. This is NOT really exciting Must See TV, but it does give you an idea of how long it takes for the dishwasher to clean the dishes in it. By my count, the plate the GoPro is focused on took about two and a half minutes to get clean. This sort of proves my point I'll just take the 2 minutes it takes and wash them myself!
