Why Do I Need to Use an Antimicrobial Soap with Persistent Activity? What’s the Difference?

It is dependent on the procedure you are performing. Defined an antimicrobial agent is any agent that kills or suppresses the growth of microorganisms. If you are doing a surgical procedure or anticipate a surgical procedure you need to use an antimicrobial soap. The CDC states that you can use a non-antimicrobial or antimicrobial soap and water when hands are visibly dry or contaminated with blood or other potentially infectious material.
