Step 1 is important because we are using soap. When soap is mixed with water, it lathers up to form bubbles that act like pockets. These bubbles trap and remove germs and chemicals found on your hands. Soap makes the germs slippery and slides off when washed with water.

Step 2 is important because water washes away the germs. The soap makes the germs slippery and the water makes the germs slide off of your hands down into the drain. It is important to wash your hands for 20 seconds because these actions physically destroy germs and remove germs and chemicals from your skin.

Step 3 is important because drying your hands reduces the spread of germs. Germs spread more easily when hands are wet, so it is important to dry your hands completely. Using a dryer or paper towels are both effective, however disposable paper towels are best.
