How Often Should Sydney Restaurants Clean Kitchen Exhaust Ducts?

A practical guide to setting cleaning frequency for commercial kitchen hoods and duct systems in Sydney.

For many Sydney restaurant operators, the biggest challenge with exhaust hygiene is knowing the right cleaning interval. Waiting too long allows grease to accumulate in canopy sections and duct runs, increasing fire risk and reducing airflow performance. Cleaning too frequently, on the other hand, can create unnecessary operating costs.

The best schedule depends on menu type, cooking load, and service hours. High-volume kitchens that run fryers, chargrills, or wok stations generally need more frequent hood and duct cleaning than low-grease operations. A practical baseline is to begin with a structured inspection and then set a recurring cycle based on visible grease load and extraction performance.

At RS Hygiene, we recommend building a maintenance schedule that matches your kitchen reality, not a generic template. This includes after-hours service windows, clear before-and-after reporting, and routine review of fan and duct condition. When cleaning is planned properly, venues usually see better airflow, fewer emergency callouts, and stronger compliance confidence across the year.
