The ISSA Clean Standard: Institutional and Commercial applies to institutional and commercial facilities, including office buildings, retail stores, hotels, and other similar facilities. It derives from extensive research in K-12 schools, but has been restructured in part to make it applicable to and easier to use in a wide variety of institutional and commercial facilities.
Measuring Cleaning Effectiveness
The ISSA Clean Standard: Institutional and Commercial relies upon both objective and subjective components in setting forth a methodology for measuring cleaning effectiveness. The Standard specifically provides "ranges of clean" based on ATP testing as well as sample audit forms. The inclusion of ATP limits adds a quantitative element to the determination, while the audits assist with a traditional "sight, smell, and touch" perspective. The ultimate goal is to ensure that facilities are in a condition that is clean, safe and healthy for students and staff. More importantly, the ISSA Clean Standard: Institutional and Commercial calls for corrective actions in the event the facility is not achieving the desired level of cleaning effectiveness.
