Cleaning vs Disinfecting

What is the difference between cleaning and disinfecting • From the CDC, “Cleaning and Disinfection for Households” (https: //www. cdc. gov/coronavirus/2019 -ncov/prevent-gettingsick/cleaning-disinfection. html), the difference between cleaning and disinfecting: • Cleaning refers to the removal of germs, dirt, and impurities from surfaces. It does not kill germs, but by removing them, it lowers their numbers and the risk of spreading infection. • Disinfecting refers to using chemicals, for example, EPA-registered disinfectants, to kill germs on surfaces. This process does not necessarily clean dirty surfaces or remove germs, but by killing germs on a surface after cleaning, it can further lower the risk of spreading infection MIT ENVIRONMENT • HEALTH • SAFETY 2
