Regular kitchen duct cleaning is essential for maintaining fire safety and proper hygiene. In commercial kitchens, daily cooking produces grease, oil, and smoke that gradually build up inside the duct system. If not cleaned on time, this buildup can restrict airflow, cause unpleasant odors, and significantly increase the risk of kitchen fires.

The ideal cleaning frequency depends on kitchen usage. High-volume kitchens such as restaurants, hotels, and cloud kitchens should schedule duct cleaning monthly or quarterly. Medium-use kitchens usually require cleaning every 3–6 months, while low-use kitchens can be maintained with annual duct cleaning. Routine inspections and scheduled maintenance help ensure smooth ventilation and a safer kitchen environment.
