Store the dispenser at 68- to 77-degrees Fahrenheit. The product is less effective when exposed to extremely hot or cold temperatures.
Roll up your sleeves. Purell may discolor fabrics is spilled onto clothing.
Hold one hand underneath the dispenser's nozzle.
Depress the nozzle with your other hand. This will pump one squirt of liquid onto your palm. This is enough for a child or adult with smaller hands. If you have large hands, dispense a second squirt onto your hand. You just need enough liquid to coat both hands in a thin layer of Purell.
Rub both your hands together, working the Purell sanitizing solution over both the front and back of your hands. Continue to rub briskly until your hands are dry. When the sanitizing solution has dried, your hands are effectively sanitized.
- The 99.99-percent effectiveness of Purell is misleading, as it only applies to "common" bacterial strains. While Purell does kill most germs, it doesn't eliminate every type of bacteria, and it is even less effective on viruses. Antibacterial soaps are useful after using Purell for further sanitizing.
