Cleaning Inspections measure a building’s cleanliness and the effectiveness of the Cleaning Provider’s cleaning process control which is part of the routine duties of a Cleaning Supervisor. Contractually agreed cleaning audits serve a different purpose; they assess the conformance of a building’s cleanliness with contractually pre-agreed specifications and outcomes. In-house and/or third party auditors are expected to become a norm of Outcome-based Facilities Management & Maintenance contracts.

Assessment of cleaning outcomes/results by a Cleaning Supervisor or Auditor involves senses (mainly visual, smell and touch) which can lead to subjectivity problems. Tests such as adenosine triphosphate (ATP) may be specified where health & safety and/or production processes are compromised by work not done/not done to the performance specified. Evidence of work execution and performance execution can also be verified by records and reports. Notwithstanding, the subjectivity issue in Cleaning Inspections and Audits need to be resolved for effective cleaning inspections and audits.

The Netherlands Association for Cleaning Research (VSR) has been striving for more than 35 years to objectify and professionalize the cleaning profession through research, information and training. VSR has developed tools and techniques to produce accurate results and good judgement when inspecting and auditing any cleaning operations in the built environment. VSR’s work forms the basis of Dutch Standard NEN 2075 (2018 en): Quality Measuring System and Process Control System for Cleaning Performance and is linked to EN 13549 (2001): Cleaning Services Basic Requirements and Recommendations for Quality Measuring Systems’. Singapore Standard SS499: Cleaning Performance for Commercial Premises takes reference from NEN 2075; i.e. by default VSR’s tools and techniques.
