Are germs susceptible to centrifugal force?

Question

If I swung a towel that might be dirty in circles as fast as I could, would the germs be pushed away by the centrifugal force and make it "cleaner"?

Theoretically, yes. But even with all your force, you will be able to spin the towel with a maximum speed. That speed won't be sufficient to detach the germs from the towel.

What happens is the germs have a maximum force capability by which they are stuck on the towel. The centrifugal force that you create isn't enough. It works on water though. Try swinging a wet towel and you will understand what I am saying.

However, what you can do is to give the towel a jerk. That jerk gives a large acceleration to the towel which is larger than the germ's holding capacity and it will remove some (not all) the germs.
