Which is better: Soap or hand sanitizer?
Summary
This is a great title because of a coronavirus spreading now.

In fact, we often touch our face unconsciously. If viruses stick our hands, those will infect us. For protecting us from it, we can use soap and water or hand sanitizer.

In this coronavirus situation, the answer about which one is better is that in a water-rich environment, using water to wash your hands is effective and easy and with soap, it’s more effective. It needs one or two seconds. However, doctors recommend at least 20 seconds of hand-washing because our hands' landscape is intricate. The story didn’t say that l think sanitizers should keep for medical practitioners. 1)
If you don’t have access to clean drinking water, by using salt, water, and a car battery, you can make chlorinated water that kills harmful pathogens. It’s safe for your handwashing. 2)
On the go, hand sanitizers are more convenient to use. Just rub your hands together with it until drying. 3)

The process of destroying the virus of the coronavirus is below.
The coronavirus lipids are pin-shaped molecules and its heads can be attracted to water well. By water, those are repulsed and by soap, those are broken.
Hand sanitizers work to collapse the cell membrane.
In the coronavirus situation, both methods are effective, though, for other virses, we need the advice of accredited medical professionals.

Don’t forget to wash your hands, please.
