Depending on the nature of your work in the cleanroom and what exactly it is you're are trying to elminate with the cleaning will best determine the type of chemical needed. Because your question pertains [...]

I have found two schools of thought. One school says you need to remove contamination from you hands prior to handling Cleanroom garments in the Gowning Room by using a "hands-free" sanitary hand washing station with a sink and a HEPA filterd dryer. The other school says to use only sanitary wipes or solution prior to handling Cleanroom garments because the sinks are a source of bioactivity that could contaminate the Cleanroom with bacteria and mold.
I would appreciate any guidance that members of the forum could provide.

While colony forming unit (CFU) measurements in "controlled environments" display the typical negative exponential histogram character usually seen for particle measurements, in "dirtier" environments, the histogram changes to a "normal" i.e. a Gaussian distribution.
In a controlled environment, one would expect alert levels of 3*mean and action levels of 4.6*mean, In ISO Class 7&8 environments the alert levels change to mean +1.65*std dev'n and action levels change to mean +2.33*std dev'n. This information is described in a 2004 Cleanrooms East Conference paper. copy of Cleanrooms Magazine may be able to supply a copy of the full paper “Establishing and Environmental Monitoring Program”.
Other information sources on this topic include:
1. NSF publication “Environmental Monitoring” available at http://www.cerhb.ufl.edu/pdf/edcenter/environmental_monitoring.pdf/
Action and alert levels for ISO Class 7 & 8 environments are presented on page 25 of this document.
2 “Microbial Limit and Bioburden Tests: Validation Approaches and Environmental Limits” 2nd ed., Lucia Clontz, Taylor and Francis Group, 2009.
3. US-American Pharmacopoeia (USP), “Microbiological Evaluation of Clean Rooms and Other Controlled Environments”, USP 26 .

Far more compelling are the "in operation" data which reflect what the devices are seeing during normal operating conditions.
