I wonder if this is like dishwasher usage. As a kid growing up we never used the dishwasher. It was just the drying rack. The reason was you had to rinse off the big stuff anyways, and then the resulting quality of dishwashing was poor in it. You'd often get a fork with rice stuck between it still, which was unacceptable.

As a grown up now I use a dishwasher for everything that is permitted to go in it. I still have to rinse off plates first, and occasionally I do see rice between a fork that I have to then clean manually. But I'm not comfortable knowing that it won't clean as well as I could by hand, but it does a good enough job -- and in some ways a much better job (it uses much hotter water than I do by hand). I don't know if my mom could ever really be comfortable with it though.
