My wife is convinced that you need to hand wash dishes before putting them in the dishwasher, so she doesn't use the dishwasher (it came with the house). I actually thought the two types of people in this article were going to be A) people who hand wash dishes before putting them in the dishwasher; and B) people who just put them in the dishwasher and trust it will do its job to clean them.

It's worth mentioning that pre-washing the dishes too clean is actually worse, because the enzymes in dishwasher soap are activated with the organic matter in the food debris.
