What is the difference between cleaning sanitizing and disinfecting?
Cleaning works by using soap (or detergent) and water to physically remove germs from surfaces. This process does not necessarily kill germs, but by removing them, it lowers their numbers and the risk of spreading infection. Disinfecting kills germs on surfaces or objects.
Why is 70% alcohol a better disinfectant?
