We’re told to wash our hands for at least 20 seconds. But that doesn’t mean just rubbing your palms together while you sing “Happy Birthday” or “Stayin’ Alive”.
First of all, why soap? Soap molecules are pretty special. They have a ‘head’ that ‘loves water’ and a ‘tail’ that ‘hates water’. Because of this, soap is able to bind other water hating things like oil, dirt and germs to water. When you wash with soap, the molecules grab all the bad stuff, and allow you to wash it away.
BUT, you’ve got wash your hands properly to make sure they’re VERY clean.
