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 microbes 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 microbes on hands in some situations, but sanitizers do noteliminate all types of germs.

Hand sanitizers are not as effective when hands are visibly dirty or greasy.

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.
