the results strongly suggest that although ClO2 and sodium hypochlorite are strong antiviral agents in absence of organic matter but in presence of organic matter, ClO2 is a more potent antiviral agent against SARS-CoV-2 than sodium hypochlorite. ... disinfectant Cleverin, the major disinfecting component of which is chlorine dioxide (ClO2)

"virucidal effects of disinfectants by adding 15 μL of SARS-CoV-2 culture... to 135 μL of various disinfectants at working concentration ... With the exception of a 5-min incubation with hand soap, no infectious virus could be detected after a 5-min incubation at room temperature (22°C). Additionally, we also found that SARS-CoV-2 is extremely stable in a wide range of pH values at room temperature ... Overall, SARS-CoV-2 can be highly stable in a favourable environment,4 but it is also susceptible to standard disinfection method"

"CD at 0.25 mmol/L or 0.5 mmol/L was effective in inactivating the binding of the spike protein to ACE2.. However, CD was not effective at 0.1 mmol/L concentration. The result strongly suggests that CD in sufficient cnocentration is effective in inactivating the spike protein of SARS-CoV-2 coronavirus and thus preventing its binding to human cells."
