A new study suggests you are probably not using hand sanitizer correctly.

Researchers from the Centers for Disease Control found rubbing in hand sanitizer for exactly 30 seconds kills COVID-19. However, anything less can leave traces of active virus, leaving you vulnerable to infection.

There are a few things to keep in mind. Always use sanitizers with an alcohol content of 70-percent or more.

Rub in a generous amount for a full 30 seconds. That's about the time it takes to sing happy birthday three times.
