I do use hot water and bleach for whites. I use cold water for all else. I make sure that when I am doing whites, I get one of the dish rags(which are all white for the purpose of killing germs in the wash), and wipe down the entire inside of the washing machine that isn't gotten during reg. laundry... For example the underside of the lid, and along the edges of the machine. I too use bleach in the bathroom, and wipe down all the counters once a day for germs. I don't like using much antibacterial anthing around the house. I want my kids natural immune system to be used as much as possible.
