In the bustling food industry, cleanliness is not just about aesthetics—it’s about safety, efficiency, and compliance. One crucial yet often overlooked element of kitchen maintenance is hood cleaning. So, what does hood cleaning entail? This blog covers everything you need to know about hood cleaning, especially in the context of commercial kitchens such as those found in restaurants, hotels, and catering services across Dubai and beyond.

What Is Hood Cleaning?
Hood cleaning refers to the thorough cleaning of a kitchen’s exhaust system, which includes the hood, filters, ductwork, and exhaust fans. These components are responsible for removing heat, smoke, grease, and airborne particles generated during cooking.
Over time, grease and debris build up inside the system, creating fire hazards, reducing airflow efficiency, and violating health codes. Regular hood cleaning not only ensures a safer kitchen environment but also helps your equipment operate at its best.
Components Involved in Hood Cleaning
Here’s a breakdown of what’s typically cleaned during a hood cleaning service:
Component | Description |
Hood Canopy | The external and internal surfaces that trap smoke and grease. |
Grease Filters | Metal baffle or mesh filters that collect grease-laden vapors. |
Ductwork | The duct system connecting the hood to the exhaust fan. |
Exhaust Fan | The rooftop or wall-mounted fan that pulls air through the system |
Step-by-Step: What Hood Cleaning Entails
- Initial Inspection
Technicians examine the entire system to identify areas with heavy buildup and assess access panels.
- Protective Setup
Floors, countertops, and appliances are covered with plastic sheeting to protect them from grease and water.
- Filter Removal and Soaking
Grease filters are taken out and soaked in a degreasing solution to break down accumulated fats and oils.
- Scraping and Degreasing
Professionals scrape thick grease from the hood and ducts, then apply degreasing chemicals to dissolve residue.
- High-Pressure Washing
Using hot water pressure washers or steam, the system is flushed clean, removing loosened grime.
- Fan Cleaning
The exhaust fan is dismantled (if accessible) and cleaned thoroughly, including the blades and housing.
- Final Rinse and Polish
All cleaned areas are rinsed, dried, and polished to restore their original shine and performance.
- Post-Cleaning Inspection and Report
A detailed report is provided, often with before-and-after photos, to document compliance and effectiveness.

Why Is Hood Cleaning Important?
- Fire Prevention: Built-up grease is highly flammable and a common cause of commercial kitchen fires.
- Compliance with Safety Codes: Dubai Municipality and NFPA 96 guidelines mandate routine hood cleaning for commercial kitchens.
- Improved Air Quality: Clean hoods and ducts ensure better airflow, reducing smoke and odor in the kitchen.
- Energy Efficiency: A clean exhaust system reduces the strain on your HVAC and cooking equipment.
- Longer Equipment Life: Regular maintenance extends the life of fans, filters, and other components.
Frequency of Hood Cleaning
The frequency depends on kitchen usage:
Kitchen Type | Cleaning Frequency |
High-volume (fast food, 24/7) | Every 1–3 months |
Moderate-use restaurants | Every 3–6 months |
Low-volume or seasonal use | Every 6–12 months |
Common Mistakes to Avoid
- Using unqualified cleaners who lack proper training or certification.
- Skipping the ductwork and focusing only on visible surfaces.
- Using the wrong cleaning agents that may damage surfaces or leave residue.
- Delaying routine maintenance until buildup becomes dangerous or costly.
