Do they sell hand sanitizers etc., that only kill the bad bacteria?

Asked by flo (13313points) July 18th, 2018

For example they say hand sanitizers are bad because they kill the good bacteria too.
1)Why are they being sold?
2)Why don’t they make the kind that kill the bad ones only? Or have they already, and are the ones that we see in hospitals etc. those kind? Do you have a link addressing this?
