I'm not an expert on this either, but I think it's true that IN GENERAL a lot of the value in soap is just "debulking". It does do that very well. But in the specific case of COVID-19 soap happens to also destroy the virus particles and that turns out to be pretty valuable too. :) |

We now know that people who are infected with Covid emit viral particles into the air while breathing normally. Those viral particles can float in the air for hours and the people who inhale them become infected.
> The most common way COVID-19 is transmitted from one person to another is through tiny airborne particles of the virus hanging in indoor air for minutes or hours after an infected person has been there.

Previously we thought the only transmission route was that infected people who sneeze or cough spray large droplets that fall out of the air quickly, and the people who touch surfaces contaminated by those droplets and later touch a mucous membrane become infected.
So Covid has fully airborne transmission like the measles, not a droplet based spread like the flu. Hand washing is an effective mitigation for a virus with a droplet based spread, but not a virus with an airborne spread.
The Whitehouse post linked above discusses the sorts of mitigations that can be effective against an airborne virus.
