Here's something I didn't know about alcohol based hand cleaners:
In a hospital setting, health-care workers use medicated soap and water
wash or alcohol-based hand rub to remove germs and kill pathogens.
Alcohol-based hand rub has the added bonus of providing an additional 20
minutes of residual action on the surface of the health workers’ hands
to keep pathogens from multiplying to a level that can cause infection
in vulnerable patients.
