- When shopping for hand sanitizer, make sure you choose a sanitizer that contains between 60-95% alcohol.
- Also, when you use hand sanitizer, make sure you do so the right way. Find the directions on the back of the bottle and follow the proper technique.
- Generally, apply the liquid to the palm of one hand. Then rub it all over both hands until the sanitizer dries. This takes about 20 seconds.
- Be careful not to wipe the sanitizer off before it’s dry. Doing that can make it not as effective in killing germs.
