Let your immune system handle it.
Use regular soap and water.
The obsession with anti bacterial soaps is an example of what I believe is being expressed here.
I once went to pick up a prescription. You know how they make you sign for it? I used the pen and then asked for some Purell. She didn't have any at the counter. I kept asking till they got some. Think about it. Every one who is sick is using that same pen to sign for their prescriptions. Some time anti-bacterials are needed.
