Cleaning and disinfecting are not the same thing, though often used synonymously. Disinfecting is KILLING the bacteria and viruses on a surface. While cleaning is the REMOVING of VISIBLE foreign mater from a surface. It is possible to be clean but not disinfected, and similarly disinfected but not clean.
CLEAN but not DISINFECT - In the first, case we may have a beautifully clean surface on which someone sneezes and then casually wipes the surface.
