Cleaning with products containing soap or detergent reduces germs on surfaces by removing contaminants and decreases risk of infection from surfaces.

When no people with confirmed or suspected COVID-19 are known to have been in a space, cleaning once a day is usually enough to sufficiently remove virus that may be on surfaces and help maintain a healthy facility.

Disinfecting (using U.S. Environmental Protection Agency (EPA)’s List N disinfectantsexternal icon) kills any remaining germs on surfaces, which further reduces any risk of spreading infection.
