The Centers for Disease Control and Prevention (CDC) recommends washing hands with soap and
water for 20 seconds as the top way to clean our hands. “But if soap and water
are not available, using a hand sanitizer with at least 60% alcohol can help,”
Not all hand sanitizers are the same . They have different percentages of
alcohol. The only ones that are effective against viruses are those that have
more than 60% alcohol, so look at the label when you buy your hand sanitizer.
The news media has created this sanitizer frenzy and our store
shelves are empty with people fighting each other at the stores. However, good
old fashioned soap and water is still shown to be the best way to get rid of
bacteria and viruses on our hands. Many studies have shown that hand sanitizer does
not get rid of all bacteria and viruses. In addition, it has to be used
correctly in order for it to be effective. You have to apply a decent amount on
your hands and you have to rub it in until it is dry. It takes about 30 seconds
for it to dry. If your hands a dirty or greasy, it does not penetrate the dirt
or grease and is ineffective.
So how does soap and water work and why is it better than hand
Soap is made up of molecules that have 2 ends. The one end is
attracted to fats and proteins and the other end is attracted to water. So,
take some oil and pour it into water. The oil pools in a clump. Add detergent
to it and it breaks up. This is because the fat loving end of the soap attaches
to the oil and the water end stays in the water. The water end then pulls the
Studies have shown by using a dye how much soap gets rid of germs
vs hand sanitizer and hands down, there is more dye on the hands in this study
after using hand sanitizer.
Coronavirus is an enveloped virus. This means it has a lipid or
fat layer around it. When we use soap to wash our hands, the fat loving end of
the soap attaches to the lipid wall of the virus. The water loving end stays in
the water and pulls the wall of the virus apart. The now harmless broken up
bits of virus now get washed down the drain.
So, make hand washing your number one choice. You also don’t need special antibacterial soap. All soap whether antibacterial or not has molecules that have a fat loving side and a water loving side. If you are not able to wash your hands then use a hand sanitizer but make sure it has at least 60% alcohol and that you are rubbing it all over your hands including between your fingers for at least 30 seconds until it dries.
