How does soap work? Why does it fight and kill virus?

It is fascinating how the simple science behind soap works. If you look at Coronavirus under the microscope, they are covered with spires, or spikes, giving them the appearance of a “corona”- (crown.) Underneath the crown is the virus and an outer layer of the virus made out of fat, or lipids.

Soap dissolves grease, therefore, dissolves the greasy layer coating the virus. When you dissolve the spikes and the outer layer, it physically inactivates the virus. It’s inside split open into the soap and water, and it dies.

When you rinse your hands, if you had any virus, they have been partially destroyed, trapped, or killed by soap, and now the water takes them away.

Alcohol works pretty much the same way. You do need to have a hand sanitizer that has at least 60% of alcohol in them. Just remember you have not washed away the germs yet, so the next time you are close to a sink wash them.

Our grandmother may not have had all these facts, but she was right when she would tell us: “Wash your hands.” 

Wash More Than Usual or Disinfect with Sanitizer
We are all concerned with the COVID-19 virus. There are a few things we can do to help control the spread of the disease.
The CDC recommends that we clean hands often. By washing hands with soap and water for 20 seconds during the day.
Additional times to clean hands include:
  • After using the restroom
  • After coughing
  • Before eating or preparing food
  • After contact with animals or pets
  • Before and after providing routine care for another person who needs assistance ( E.G. child)
