According to the CDC washing your hands thoroughly with soap and water for a minimum of 20 seconds is still the most effective way to clean your hands and prevent the spread of germs and illness.
But what happens when soap and water are not readily available?
According to the CDC hand sanitizer is most effective when used on hands that are not overly soiled or greasy to begin with. Be wary of homemade recipes that call for a lower concentration of alcohol. Sanitizer should be at LEAST 60% alcohol in order to not only minimize the number of microbes present but actually kill them.
Be sure to use enough hand sanitizer to completely cover the front and back of your hands and rub in until dry.

WHO recommends 2 parts Isopropyl Alcohol 99% to 1-part glycerol to maintain an effective concentration of alcohol.
50ml Isopropyl Alcohol 99%
25ml Aloe Vera Gel
Shake well before use.
*Swallowing alcohol based hand sanitizers can cause alcohol poisoning
