Bringing medical grade disinfectants or cleaning agents to residential or commercial settings will lessen the chances of spreading germs. Hospital grade disinfectants have been proven to kill a wider range of viruses, bacteria and germs that have hitch hiked to high traffic areas. Being bathrooms, family rooms, kitchen medical grade cleaning agents have a higher chance of killing germs/producing a safe environment. 

Cleaning from the bottom up prevents cross contamination. Using color coded towels helps maintain hygiene standards. Focusing on high touch surfaces should be cleaned more than others. Making sure a checklist is created ensures that germs won't spread as fast.
