I just ran across a good article on combating "enveloped viruses", such as the flu, a good many common colds, and Covid-19 - provided by our friends at CleanLink.
To summarize, an enveloped virus is one that comes with a coating (the "envelope") of fat or protein. If you puncture the envelope, you puncture the virus inside, which prevents it from transmitting (infecting). Disinfectants are quite good at doing so (viruses are generally easier to kill than bacteria or fungi). Quaternary ammonia products have been around for 85 years or so, and do quite well, though they irritate eyes and lungs, so protective gear ought be utilized. Hydrogen peroxide products, like many used in electrostatic applications, work at least as well, without the potential irritation.
An advantage of electrostatic applicators is that they coat all surfaces of the thing aimed at; wiping or pump spraying will often miss prime pathogen areas, such as sides of desks. phone handsets and the undersides of chair arms; pump sprayers also tend to apply disinfectant unevenly - some areas don't get enough dwell time, and other areas are over-wet. And, as always, dwell time is important.
A bit ago, I happened to watch a music teacher (quite a conscientious fellow, with a doctorate) sanitizing in a music classroom. He was spraying the music stands with a trigger bottle, and wiping immediately with a dry cloth. I asked him what the dell time was on the chemical (from the unlabeled bottle he'd been given) was; he didn't know from "dwell time", but knew that the chemical was referred to by administration as the "purple stuff". I mentioned that few disinfectants are effective at less than a minute's dwell time (that is, with a wet surface); he thanked me for the insight, and went back to spraying and wiping.
Good thing it's relatively hard to pick up a case of coronavirus from touching an infected surface.
