WHY ARE WE WASHING OUR HANDS WITH SOAP AND WATER?
Soap is an unusual molecule-one end is hydrophobic, the other is hydrophillic.
This means that in water the hydropphillic end acts like sugar and salt in water, it dissolves. The hydrophobic end wants nothing to do with water, but it will react with fats, oils and lipids. That's why soap is a good cleaning agent: it dissolves in water and takes fatty and oily things with it which won't dissolve in water.
COVID-19 has an outer lipid layer. The hydrophoblc end of the with soap will react with the lipid layer. This might be enough to render the virus harmless, but in any event, the hydrophillic end ensures that the soap molecule with virus attached is carried away it to a hostile environment.
Alcohol is another substance which dissolves lipids.
