What’s One SOP or Protocol You Wish Every Cleanroom Leader Would Rethink
The article discusses the importance of reevaluating standard operating procedures (SOPs) in cleanrooms, specifically focusing on the use of disinfectants. It highlights that residue from disinfectants, if not properly rinsed, can lead to bioburden and environmental monitoring issues. The recommendation is to include a residue breakdown step in SOPs to ensure optimal cleanroom performance.

Too many cleanroom teams still assume that more disinfectant is the answer, but Annex 1 makes it clear that residues left behind can quietly undermine even the most aggressive cleaning regimes. Without a deliberate residue breakdown step—such as a validated rinse—bioburden can persist beneath the surface, driving CFU formation and downstream environmental monitoring failures. Rethinking this SOP isn’t about adding effort; it’s about removing what’s hiding in plain sight so cleanrooms can perform as designed.
