Wash or Squirt?
Most respectable public health experts will tell you that hand washing with ordinary soap and water is the most effective way to remove germs from your hands. But "effective" is a questionable term. The recommendation calls for hand washing with soap and warm water for at least 20 seconds to create a full lather and to reach all crevices of your hands and wrists, as advocated on Sesame Street yet rarely put into practice.


Alcohol-based hand sanitizers kill most types of bacteria, viruses and fungi in a few seconds. While rubbing your hands with sanitizer for 15 seconds is ideal, poor hand-sanitizer use still beats poor hand washing.
And people seem to use hand sanitizers often — so much so that, from a public health standpoint, although proper hand washing is technically superior than alcohol gels most of the time, hand-sanitizer mania will likely be a more effective means to reduce disease transmission. Studies have shown how hand sanitizers reduce gastrointestinal illnesses in households and curb absentee rates in schools and workplaces.

Trash the Sink?
Alas, you can't rely solely on alcohol-based hand sanitizers. Alcohol can kill bacteria but not necessarily clean your hands. That is, it does not remove dirt, which includes organic material such as blood or feces. Soap and water must be the first choice in restrooms.
Also, there are a few key germs that alcohol doesn't kill well, such as the norovirus or E. coli, which is why soap and water is best during cooking, too.
