Scientists say that the worst enemy of the virus is that cheap soap by your sink.
That is because of simple chemistry. In soap lather, a combination of molecules assemble into bubble-like structures called micelles that trap viral matter and other biomaterialsógrease, oil, dirtóand rinse them down the drain.
One side of the soap molecule (the one thatís attracted to fat and repelled by water) buries its way into the virusís fat and protein shell. Fortunately, the chemical bonds holding the virus together arenít very strong, so this intrusion is enough to break the virusís coat.
Then the harmless shards of virus get flushed down the drain. And even if it the soap doesnít destroy every virus, youíll still rid them from your hands with soap and water, as well as any grease or dirt they may be clinging to. Soap will also wash away bacteria and other viruses that may be a bit tougher than coronavirus, and harder to disintegrate.
The trick is this all takes a little time to happen, and thatís why you need to take at least 20 seconds to wash your hands.
