Where the dust enters and what actually reduces it
Most of it arrives on footwear and through open doors, with a smaller contribution settling from the air. That means the entry is where the intervention belongs. Longer matting, more frequent mat maintenance and a sweep of the external approach before opening will do more than any increase in internal cleaning frequency, because they intercept the material before it is distributed across the floor.
External approach cleaning is the item most often missing. If the path from the car park is dusty at eight in the morning, every customer and staff member carries some of it inside for the rest of the day. A pre-opening sweep of that approach costs very little and changes the internal load noticeably, provided the approach is within the tenancy's responsibility to clean.
