The Centers for Disease Control and Prevention, the CDC, lays out six core components for an environmental cleaning program:
Integrate Environmental Services, EVS, into the facility’s safety culture
Train staff properly
Select the right products
Standardize protocols by setting
Monitor how well those protocols are actually followed
Feed that information back to the people doing the work
CDC is explicit about one thing that gets lost in the summary version: these six work as a system, not a menu. You don’t get to run four of them well and skip the other two. Skip any one, and the whole program is weaker than the sum of its parts.
