The CDC [recommends](https://www.cdc.gov/handwashing/when-how-handwashing.html) scrubbing for a full 20 seconds.

20 seconds

How long should you scrub your hands for, at a minimum?

According to the [CDC](https://www.cdc.gov/handwashing/when-how-handwashing.html), humming the tune of "Happy Birthday" two times will get you to the recommended 20 seconds of handwashing.

"Happy Birthday"

What song does the CDC recommend humming TWICE while handwashing to properly measure time?

Warm or cold — they're [equally effective](https://www.cdc.gov/handwashing/when-how-handwashing.html), as long as you wash thoroughly!

Either is fine!

Is warm or cold water better for washing hands?

The CDC [notes](https://www.cdc.gov/handwashing/when-how-handwashing.html) that washing your hands with soap and water is more effective because hand sanitizer does not get rid of all germs. Still, hand sanitizer can be a great backup if you don't have access to a sink with clean water.

Soap and water

Which method of cleaning your hands gets rid of more germs?

The CDC [recommends](https://www.cdc.gov/handwashing/when-how-handwashing.html) hand sanitizers with at least 60% alcohol.

What is the minimum alcohol % that the CDC recommends for hand sanitizers?

The CDC lists some other important times to wash your hands [here](https://www.cdc.gov/handwashing/when-how-handwashing.html).

You should wash your hands in all of these situations.

In which of these situations would you NOT need to wash your hands?

The FDA has yet to find [evidence](https://www.fda.gov/consumers/consumer-updates/antibacterial-soap-you-can-skip-it-use-plain-soap-and-water) that antibacterial soaps are actually more effective at preventing illness. Their overuse may even contribute to antibiotic-resistant bacteria.

You don't need antibacterial soap.

According to the [CDC](https://www.fda.gov/consumers/consumer-updates/antibacterial-soap-you-can-skip-it-use-plain-soap-and-water), an effective handwashing session involves scrubbing the palms, backs of the hands, between the fingers, and under the nails.

You need to wash all of these!

Which of these is NOT a part of the hand you need to wash?
