Disinfect your feet. When people mop,the cleaner is always diluted. When walking barefoot,your feet step on spores, people's dead skin cells (Dandruff), animal droppings, pollen, etc. Watch an episode of a crime lab show and they can tell what's happened by what's left behind. The chlorine in your drinking water is a very diluted form of bleach, 2 of my great grandfathers died of Typhoid and cholera before they started using it. Your mother already knows this.
