Why an undefined list is a hygiene gap
Touchpoint cleaning only produces a hygiene benefit if it reaches the surfaces people actually touch. An undefined instruction reliably covers door handles and light switches, and reliably misses lift buttons, tap handles, chair arms and payment terminals, because those are less obvious. The result is a task that appears in the scope, consumes time and delivers an inconsistent outcome nobody is measuring.
Naming the surfaces solves it at no additional cost. The same amount of time produces a better result because it is directed. It also becomes checkable, which matters when a centre or a business needs to demonstrate what it does rather than simply assert that touchpoints are cleaned. That is a difference an inspector or a client can see immediately. It also lets a centre answer a question about its hygiene practice with a document rather than an assurance.
