Did you know water needs to be around 140 to 145 degrees Fahrenheit in order for it to be hot enough to properly disinfect your cups, dishes and utensils? That's one more reason why a dishwasher is better for your health than washing by hand, since most of us can't handle those extreme temps at the kitchen sink. For things you can't put in the dishwasher, like crystal, knives and cast iron, fill up the sink with the hottest water and let them soak. For cast iron, rinse and let it dry on a hot stove, so it heats up, dries out and disinfects itself at the same time.
