Cleaning Verification

Cleaning verification uses measurable methods—such as ATP testing, visual inspection against defined standards, protein swabs or microbiological sampling—to confirm that surfaces or equipment have been cleaned effectively. It is distinct from cleaning validation, which qualifies a cleaning procedure over time.

Verification transforms cleaning from a task that has been "done" into a process that has been "checked". It supports continuous improvement and provides evidence for audits.

Applied at production line changeovers, terminal cleaning in healthcare, kitchen pre-service checks, and third-party hygiene audits.
