Both are significant for the purpose of achieving your cleaning goals. Here’s the subtle distinction: cleaning entails separating filth, pathogens, and other harmful particles from the surfaces physically, as opposed to disinfecting which eliminates germs by killing them on the spot, instead of scrubbing them off the surface. The best approach when dealing with dirty spaces and surfaces is to clean first and disinfect after you’ve made everything look spotless. This way you’ll get rid of most (if not all) viruses and other nasty germs.
