What should you do if you don't have soap and clean, running water?

Washing hands with soap and water is the best way to reduce the number of germs on them in most situations. If soap and water are not available, use an alcohol-based hand sanitizer that contains at least 60% alcohol. Alcohol-based hand sanitizers can quickly reduce the number of germs on hands in some situations, but sanitizers do NOT eliminate all types of germs.

Hand sanitizers may not be as effective when hands are visibly dirty or greasy. Furthermore, hand sanitizers might not remove harmful chemicals like pesticides and heavy metals from hands. Be cautious when using hand sanitizers around children; swallowing alcohol-based hand sanitizers can cause alcohol poisoning if a person swallows more than a couple mouthfuls.

How do you use hand sanitizers?

  • Apply the product to the palm of one hand (read the label to learn the correct amount).
  • Rub your hands together.
  • Rub the product over all surfaces of your hands and fingers until your hands are dry.
