Dishwashers are truly wonderful inventions. I haven't always had one, but now I wouldn't buy a house without one. My mother died before they were available, but I'm sure she would have had one if she could. Ditto for my grandmothers, and probably their mothers as well.
It's not that I dislike hand washing dishes that much. But I have other things I'd rather do, and the dishwasher does a better job of sanitizing the dishes.
The problem with housework is that it's never finished. So I'll take all the help I can get.
