There is a lot of misunderstanding about cleaning, disinfecting and sanitizing.
Cleaning is the process of removing visible debris, dirt and dust as well as some organization in a space. Cleaning surfaces that uses soap or detergent and water may not kill all bacteria and germs but will remove some of them and lower the risk of spreading germs.
Sanitizing means reducing the level of germs that could be harmful to your health. Sanitizing reduces, not kill, the number and growth of bacteria, viruses and fungi.
Disinfecting kills microscopic organism (bacteria, viruses, fungi) on surfaces. Disinfecting does not remove visible dirt and debris from a surface and its much more effective if a standard cleaned is done first.
Disinfecting should always be done when someone in the household/workplace is ill or if someone has a compromised immune system.
