What Does Medically Clean Mean?

"Medically clean" means a surface or environment has been processed to remove or inactivate pathogens to a level safe for clinical use, verified using validated disinfection protocols rather than visual inspection. The term aligns with the Spaulding classification — critical, semi-critical, and non-critical surfaces — each requiring a different level of chemical action and dwell time under TGA-listed products.

After 25 years supporting medical cleaning contracts, three frameworks define the term. First, Standard AS 4187 (reprocessing of medical devices) and AS 4815 (office-based practice) set the procedural baseline. Second, the Commission on Safety and Quality in Health Care's National Safety and Quality Health Service (NSQHS) Standard 3 — Preventing and Controlling Infections — drives what "clean" means at audit. Third, the TGA Register of Therapeutic Goods determines which disinfectants and sanitisers can be applied in clinical zones.

Verification matters. Visual cleanliness fails the standard — a surface can look spotless and still register 1,500+ RLU on an ATP swab. Medically clean requires touchpoint testing under 30 RLU for hospitals and under 100 RLU for general clinical spaces, with the audit log retained for inspection.
