Soap vs. Hand Sanitizer: Which Cleans Your Hands Better?

Soap and hand sanitizer both help prevent the spread of germs. But they aren’t equally effective in every situation. Learn when soap and water is best, when sanitizer will do the job, and how to keep yourself healthy.

Germs are everywhere. They're lurking on stairway handrails. They’re all over the touchscreens, at the grocery store and your favorite coffee shop. They wait to hitch a ride every time you grab the gas nozzle to fill up your tank.

Germs also easily spread from person to person every time someone coughs, sneezes or simply talks. Droplets from an infected person float through the air and are inhaled by others.

They can land on anyone or anything within three feet. Germs can live for hours on surfaces like doorknobs, desks and tables. If someone touches their eyes, nose or mouth after coming in contact with a contaminated surface, they may get sick.

Fortunately, there’s an easy way to protect yourself from these germs. Health experts say keeping your hands clean is one of the best ways to avoid getting and spreading bacterial illness or viruses.

It's impossible to keep your hands germ-free all the time. But frequent hand washing limits the transfer of bacteria and viruses. You only need soap and water or an alcohol-based hand sanitizer to clean your hands.

Which Is Better: Soap or Hand Sanitizer?

Washing your hands with soap and water is the best option for getting your hands clean, says the Centers for Disease Control and Prevention.  

Alcohol-based hand sanitizers are considered a safe and effective alternative when you can’t wash with soap. But washing with soap and water is your best choice for really getting clean. Sanitizer can kill many germs, but soap removes all germs, dirt and grease from your skin.

How to Wash Your Hands Properly

The Cleveland Clinic says any soap will do for getting your hands clean. How you wash is more important than what soap you use.

Here’s a simple how-to:

1. Wet your hands with clean, running water. Any comfortable temperature works.
2. Apply soap and lather up. Scrub all surfaces of your hands and wrists. Be sure to clean the backs of your hands and wrists, between your fingers, and under your fingernails.
3. Scrub your hands for at least 20 seconds. Hint: To get the time right, sing the “Happy Birthday” song twice while you wash your hands.
4. Rinse well under clean, running water.
5. Dry your hands with a clean towel or an air dryer. Hint: Use a towel or your elbow to turn off the faucet when you can.

When Should You Use Hand Sanitizer?

Hand sanitizer is a portable way to get the germs off your hands when soap and water aren’t available. Not all hand sanitizers are the same, though. Choose one that is at least 60 percent alcohol.

Alcohol-based hand sanitizers can kill bacteria and some viruses. They do not work against norovirus, a common virus that can cause serious illness.

When Should You Clean Your Hands?

There are some good rules of thumb to follow to protect your health.

Lather up before:

• Cooking and eating
• Inserting and removing contact lenses
• Treating wounds, giving medicine, and caring for sick or injured people

Lather up after:

• Using the bathroom or changing a diaper
• Touching an animal or animal toys, leashes or waste
• Handling garbage or household or garden chemicals
• Blowing your nose, coughing or sneezing into your hands

Start scrubbing to stay healthy.
