The room looks fine and the outcome is poor
Dust in a static store does not create the visual mess that a busy area does. There is no debris, no packaging on the floor and no traffic marking, so the room reads as adequately maintained. The problem only surfaces when a chair, a desk or a partition is brought out and carried onto a floor where people work, arriving grey and needing attention before it can be used. That is a facilities problem created months earlier in a room nobody thought needed cleaning.
A modest periodic attendance reduces the general dust level and slows what settles on the stock. It does not eliminate it, because covered items still collect dust on their covers, but it makes the difference between an item that needs a wipe and one that needs a proper clean before it can be deployed. Covered items still collect dust on their covers, which is worth saying plainly.
