What is the correct minimum time for alcohol-based hand rub to be effective?
What is the correct minimum time for alcohol-based hand rub to be effective?
Tap to reveal answer
Rub for at least 20 seconds until hands are dry. Alcohol-based rubs require sufficient contact time to denature proteins and inactivate a broad spectrum of microorganisms on the skin.
