A clean commercial oven hood isn’t just about having a tidy kitchen—it’s a legal requirement, a fire safety essential, and a key factor in keeping your kitchen running at peak efficiency. Whether you operate a restaurant, cloud kitchen, food truck, bakery, or industrial food facility, regular commercial hood cleaning is critical to preventing grease fires, improving airflow, and staying compliant with safety codes.
This guide will walk you through everything you need to know, including cleaning methods, how often to clean your hood, inspection standards, cost expectations, and how to choose the right cleaning service.
What Is Commercial Oven Hood Cleaning?
Commercial oven hood cleaning is the process of removing grease, smoke residue, and airborne contaminants from:
- The hood canopy
- Filters
- Grease trays
- Exhaust fan
- Ductwork
- Ventilation system
Over time, these areas collect grease deposits, which are highly flammable. Proper cleaning ensures your kitchen stays safe and functional.
Why Commercial Hood Cleaning Is Critical
1. Fire Safety
Grease buildup can ignite instantly if exposed to a flame or high heat source. Most commercial kitchen fires start in the exhaust system.
2. Compliance With Regulations
Fire codes like NFPA 96 require commercial kitchens to maintain and clean hoods regularly. Failure can lead to fines, shutdowns, and insurance claim rejections.
3. Improved Airflow & Ventilation
Clean hoods remove smoke, heat, and odors more effectively—keeping staff comfortable and equipment efficient.
4. Extended Equipment Life
Regular maintenance prevents costly repair or replacement of fans, filters, and ductwork.
5. Better Workplace Hygiene
A clean hood ensures a healthier environment and supports food safety standards.
How Often Should Commercial Hoods Be Cleaned?
Cleaning frequency depends on how heavily your kitchen is used:
| Kitchen Type | Cleaning Frequency |
|---|---|
| High-volume restaurants, fried/grease-heavy cooking | Every 1 month |
| Standard commercial kitchens | Every 3 months |
| Cafeterias / hotel kitchens | Every 3–6 months |
| Low-volume or seasonal operations | Every 6–12 months |
| Food trucks / cloud kitchens | Every 1–3 months |
Tip: Always check national/state fire code requirements, insurance conditions, and inspector reports.

3. Duct Cleaning
Grease buildup is scraped and chemically treated throughout duct lines.
4. Exhaust Fan Cleaning

DIY vs Professional Cleaning
| DIY Cleaning | Professional Cleaning |
|---|---|
| Can handle surface buildup only | Removes grease deep inside ducts & fans |
| Good for daily maintenance | Required for legal compliance |
| Lower cost | Higher safety & long-term savings |
| Risk of incomplete cleaning | Certified, documented, inspection-ready |
Legal note: Most regions require certified hood cleaning for commercial kitchens. DIY alone is rarely sufficient.
Commercial Hood Cleaning Cost Breakdown
The cost depends on:
- System size & length of ductwork
- Number of hoods and fans
- Grease buildup level
- Kitchen usage frequency
- Accessibility (rooftops, tight ducts, etc.)
Average cleaning cost: $250 to $1,500+ per cleaning, depending on scale.
Restaurants that wait too long between cleanings generally spend more due to heavy buildup removal.
Signs Your Hood System Needs Immediate Cleaning
- Grease dripping or visible residue on hood surfaces
- Strong, lingering smoke or burnt odors
- Reduced airflow or noisy exhaust fan
- Filters appear dark, sticky, or clogged

If any of these are happening — schedule cleaning ASAP.
