Such great information, thank you all. All I can contribute is relaying the studies, same ones MBIB that you probably know about. That under very high virus load (not the typical kind of exposure/load), under ideal circumstances, on SOME surfaces like stainless steel enough virus remains viable to be potentially infectious for 72 hours, but even the study said this was a worst case scenario. The material makes a big differences, including how long the virus stays in moisture. So droplets obviously are more of an issue.
But 24 hours is a pretty good guidelines. Everything is odds and statistics and its all about maximizing the odds in your favor. Keep in mind that covering surfaces with soapy water and leaving it on for a minute or two should also do a pretty good job of destroying the virus. Disinfectant wipes aren’t as effective as people may think, as you have to wet the surface and leave it on for minutes (5 or more) from what I have read.
