The more porous or uneven the surface the more difficult antimicrobial
effectiveness becomes. However, normally it is not our lab studies that
show this deficiency as it is exactly that, a lab study and not
application in the clean room. It is normally in our "in situ" (field)
studies or in daily operations where we notice possible differences as
application and dry time of the disinfecting agent on the surface may
vary from area to area. The field studies bring together antimicrobial
effectiveness and our cleaning SOP's. If we pass antimicrobial
effectiveness and fail the field studies, we need to revisit our cleaning
SOP's as they may be lacking in their content.
