It is fairly well known that the class of viruses that the coronavirus belongs to is fairly fragile. I think my question comes down to; does soap actually make any real difference in a case where almost everything destroys the virus? The only viruses that survive are pretty much only those that are embedded in some other substance. That would mean that the discussion on Twitter about soap coming intro direct contact with the virus was pointless.
One source suggested that the reason that soap is better was simply because it caused people to wash their hands for longer.
