Frequency depends on foot traffic, industry type, and office size. A commercial cleaning company typically recommends daily cleaning for high-touch areas like restrooms and breakrooms, with weekly deep cleaning for carpets and workstations. Medical or food-service facilities may require nightly sanitation. For low-traffic offices, bi-weekly service often suffices. A professional assessment can tailor a schedule that balances hygiene, budget, and operational needs without over-cleaning or missing critical zones.
