Basic knowledge of hand sanitizer

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. 

When using hand sanitizer, apply the product to the palm of one hand (read the label to learn the correct amount) and rub the product all over the surfaces of your hands until your hands are dry. 

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 may not be as effective when hands are visibly dirty or greasy. 

Swallowing alcohol-based hand sanitizers can cause alcohol poisoning. 

Hand sanitizers might not remove harmful chemicals, like pesticides and heavy metals, from hands.
