Overhead dust can collect on exposed ductwork, pipes, beams, decorative ledges, ceiling fan housings and light fixtures. In an open-ceiling dining room, those surfaces are part of what guests see. They can also release settled dust when air movement or maintenance disturbs them.
High dusting should be completed before detailed cleaning of tables, counters and floors. Depending on height and access, cleaners may use extension tools, high-efficiency vacuum attachments or approved access equipment. Fixtures must be cool, stable and safe to approach. Cooking equipment and exposed food-contact items should be protected or removed from the work area.
This work is commonly set on a periodic schedule rather than added casually to every visit. Frequency depends on ventilation, exposed architecture, cooking activity and the speed at which visible dust returns. An inspection provides a better basis than an arbitrary interval.
