Routine cleaning is the everyday cleaning practices that businesses and communities normally use to maintain a healthy environment. Surfaces frequently touched by multiple people, such as door handles, bathroom surfaces, and handrails, should be cleaned with soap and water or another detergent at least daily when facilities are in use. More frequent cleaning and disinfection may be required based on level of use. For example, certain surfaces and objects in public spaces, such as shopping carts and point of sale keypads, should be cleaned and disinfected before each use. Cleaning removes dirt and impurities, including germs, from surfaces. Cleaning alone does not kill germs, but it reduces the number of germs on a surface.
