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

Here's a link to some scientific info about the novel corona virus and how to kill it.  Jack posted it on FaceBook with his summary, which I copy here:
Persistence of coronaviruses on inanimate surfaces and their inactivation with biocidal agents

Here's a meta-analysis, just published, that concludes that a cationic detergent like benzalkonium chloride is less effective against human coronaviruses in general than ethanol, bleach, or hydrogen peroxide; it doesn't discuss household soap or detergent:

The analysis of 22 studies reveals that human coronaviruses such as Severe Acute Respiratory Syndrome (SARS) coronavirus, Middle East Respiratory Syndrome (MERS) coronavirus or endemic human coronaviruses (HCoV) can persist on inanimate surfaces like metal, glass or plastic for up to 9 days, but can be efficiently inactivated by surface disinfection procedures with 62–71% ethanol, 0.5% hydrogen peroxide or 0.1% sodium hypochlorite within 1 minute. Other biocidal agents such as 0.05–0.2% benzalkonium chloride or 0.02% chlorhexidine digluconate are less effective.
