I was at the doctors office the other day and noticed my doctor washing his hands (with soap) with very hot water. I asked him about it and he said that the hot water is cleaner since it has gone through a heater, whereas cold water could have any type of germ attached. He said that cold water is not good for you as many organisms can live through the chemicals (just look through a microscope at cold tap water) and hot water has much less to none. Has anyone else heard this? What temperature water do you wash your hands with?
