Persistence of coronaviruses on inanimate surfaces and their inactivation with biocidal agents

On just plain soap:

1/25 Part 1 - Why does soap work so well on the SARS-CoV-2, the coronavirus and indeed most viruses? Because it is a self-assembled nanoparticle in which the weakest link is the lipid (fatty) bilayer. A two part thread about soap, viruses and supramolecular chemistry
2/25 The soap dissolves the fat membrane and the virus falls apart like a house of cards and "dies", or rather, we should say it becomes inactive as viruses aren’t really alive. Viruses can be active outside the body for hours, even days.
3/25 Disinfectants, or liquids, wipes, gels and creams containing alcohol (and soap) have a similar effects but are not really quite as good as normal soap. Apart from the alcohol and soap, the “antibacterial agents” in these products don't affect the virus structure much at all.
4/25 Consequently, many antibacterial products are basically just an expensive version of soap in terms of how they act on viruses. Soap is the best but alcohol wipes are good when soap is not practical or handy (e.g. office receptions).
The right way to test - outdoors in your car, like in South Korea. Latest data is that the virus can linger in air for up to 30 minutes.:
Countries with effective control efforts have linear growth curves:
