Running a restaurant or food business in Dubai means keeping your kitchen spotless, functional, and compliant with health and safety regulations. One of the most important yet overlooked aspects of commercial kitchen maintenance is cleaning the exhaust hood system.
So, how long does it take to clean a commercial kitchen hood? The answer depends on several factors, including the size of the system, grease buildup, cleaning frequency, and whether you’re hiring professionals or doing it in-house. Let’s break it down so you can plan efficiently and avoid unexpected downtime.
Why Commercial Kitchen Hood Cleaning Matters
Before getting into the timing, it’s important to understand why kitchen hood cleaning is essential.
In Dubai’s fast-paced culinary industry, commercial kitchens generate a significant amount of smoke, steam, and grease daily. Over time, this builds up inside the hood system, especially in the exhaust ducts and fans. If left uncleaned, it leads to:
- Fire hazards
- Decreased air quality
- System inefficiency
- Unpleasant odors
- Health and safety violations
The Dubai Municipality mandates regular hood cleaning for food establishments to prevent such risks. That’s why understanding the time it takes is not just about convenience but also about maintaining a safe and compliant business.
Typical Time Frame for Cleaning a Kitchen Hood
1. Light Cleaning (1 to 2 Hours)
If your kitchen hood is cleaned frequently – say, every month or two – the process is quicker. Professionals typically spend 1 to 2 hours for light cleaning jobs. This includes:
- Removing minor grease and residue
- Wiping down hood filters and surfaces
- Basic fan and duct inspection
2. Moderate Cleaning (3 to 4 Hours)
If it’s been 3 to 6 months since the last cleaning, expect the process to take about 3 to 4 hours. This level involves:
- Removing and soaking filters
- Scraping and degreasing fan blades
- Cleaning interior ducting
- Polishing the hood exterior
This is common for medium-traffic kitchens like hotel cafeterias or mid-sized restaurants.
3. Deep Cleaning (5 to 8+ Hours)
For hoods that haven’t been cleaned in over 6 months, or those in high-volume kitchens, deep cleaning is required. These can take up to 8 hours or more, depending on:
- Amount of hardened grease
- Length and layout of ductwork
- Access to internal components
- The need for temporary disassembly
In some cases, cleaning is done overnight to avoid disrupting operations during peak hours
Key Factors That Affect Cleaning Time
1. Kitchen Usage
Kitchens operating 12+ hours daily generate more buildup. More use equals more cleaning time.
2. Type of Food Prepared
Fried or greasy foods tend to clog hoods faster than boiled or baked dishes. Indian, Chinese, and Middle Eastern cuisines in particular cause heavy grease accumulation.
3. Duct Length and Design
Longer and more complex duct systems take longer to clean because more components must be accessed and scrubbed.
4. Access Points
If the system lacks proper access panels, cleaners may need extra time to reach internal areas.
5. Equipment Condition
Old or neglected equipment often needs extensive degreasing, possibly replacement of filters or parts, extending the overall time.
Professional Cleaning vs. In-House Cleaning

Some businesses try to handle hood cleaning in-house, but there are key differences:
| Aspect | In-House Cleaning | Professional Cleaning |
| Time | 6 – 10 hours or more | 2 – 5 hours on average |
| Tools Used | Basic brushes, soaps | Industrial-grade vacuums, steamers, degreasers |
| Efficiency | Often superficial | Deep, code-compliant cleaning |
| Safety | Higher risk | Fully insured and certified |
Hiring professionals is not only faster but also ensures your system meets Dubai’s health and safety codes.
How Often Should You Schedule Hood Cleaning?
While timing depends on your kitchen type, here’s a general guideline followed by many Dubai-based kitchens:
| Type of Kitchen | Recommended Cleaning Frequency |
| Fast Food / 24-Hour Restaurants | Monthly |
| Cafés / Casual Dining | Every 2 – 3 Months |
| Hotel Kitchens | Quarterly |
| Light Cooking Areas | Every 6 Months |
Sticking to a schedule also shortens future cleaning times, saving you hours and money.
Tips to Speed Up Kitchen Hood Cleaning
- Clean filters weekly to reduce long-term buildup
- Install access panels for better reach into ducts
- Label components for easier reassembly
- Use degreasing agents regularly for minor cleaning
- Hire professionals on a schedule to avoid emergency cleanings
The more you maintain, the quicker the deep cleans.
Consequences of Delaying Hood Cleaning
Letting your hood system go unchecked for long periods can lead to:
- Emergency shutdowns
- Foul kitchen odors
- Oil dripping from the hood
- Violations and fines from Dubai authorities
- Insurance issues in case of fire
Delays also increase cleaning time significantly and may even require duct replacements.
