How Soap Kills the Coronavirus

Soap is the ultimate virus annihilator. We've heard about washing your hands for 20 seconds, and we've heard about how important it is to stop the spread of coronavirus. We've even learned tricks to calculate those 20 seconds. However, that lesson makes a lot more sense when you know exactly how it works. That 20 second rule isn't just the optimum time to wash your hands, it's the minimum time for soap to be effective. So soaping up for ten seconds and rinsing, then soaping up for another ten seconds just doesn't do the trick. If we do it right the first time, any coronavirus on our hands will die.
