A few days ago everyone in the office where I work received an email asking them to clear their desks because the cleaners would be using a special anti-coronavirus spray on them. The odds and ends at the back of my desk had been there for some time, so removing them exposed a thick layer of dust.
I can report that the cleaners have apparently managed to apply the magic prophylactic spray every day this week without disturbing the dust.
So it's not always the cleaners that do it.
Biting the hand that feeds IT
