Since the outbreak of COVID-19, sales of hand sanitizers have soared. Hand sanitizers can protect against disease causing microbes, especially in situations when soap and water aren't available. Not all hand sanitizers are equally effective against corona virus.
There are 2 main types of hand sanitizers : alcohol-based and alcohol free. Alcohol-based hand sanitizers contain varying amounts and types of alcohol, often between 60 percent and 95 percent. Alcohol is known to be able to kill most germs.
Alcohol free hand sanitizers contain usually benzalkonium chloride instead of alcohol. These can reduce microbes but are less effective than alcohol.
