Kitchen Exhaust Fan Cleaning Tips for Better Airflow
In any commercial kitchen, the exhaust fan plays a vital role in maintaining clean, breathable air by pulling out hot air, grease particles, steam, smoke, and odours. Over time, however, the fan blades and motor components get coated in thick layers of grease and grime. If neglected, this build-up not only affects air quality but also reduces airflow, raises fire risks, and increases energy consumption.
Proper and regular maintenance is essential to keep your kitchen safe, efficient, and compliant with health and safety standards. In this article, we’ll share essential kitchen exhaust fan cleaning tips to improve airflow and extend the life of your ventilation system. And if you’re looking for professional services across Australia, Hygene Hood Cleaning is the name to trust. Visit hygenehoodcleaning to schedule a consultation.
Why Cleaning Your Kitchen Exhaust Fan Matters
The exhaust fan is a key part of your commercial kitchen’s ventilation system. When functioning correctly, it helps:
- Remove heat, smoke, and odours from cooking
- Filter out airborne grease and oil particles
- Prevent build-up in ductwork and canopy hoods
- Maintain consistent airflow and temperature
- Comply with fire safety and hygiene regulations
If neglected, the accumulated grease can harden, obstruct airflow, and cause the fan motor to work harder than it should. This not only reduces its efficiency but can also lead to overheating, breakdowns, or even fire.
Signs Your Kitchen Exhaust Fan Needs Cleaning
Wondering if it’s time to clean your exhaust fan? Watch for these common indicators:
✔ Poor ventilation or lingering smoke and smells
✔ Louder-than-usual fan operation
✔ Visible grease or oil dripping from the fan housing
✔ Fan blades coated in grime
✔ Reduced airflow or suction power
✔ Overheating or sudden shut-offs
If you’ve noticed any of the above, it’s time to roll up your sleeves—or better yet, call the experts of Hygene Hood Cleaning at +61-452-638-894.
Tools You’ll Need for Cleaning
Before starting, gather the necessary tools and safety gear:
✔ Screwdriver set
✔ Degreasing solution (preferably commercial-grade)
✔ Non-abrasive scrub brushes
✔ Microfibre cloths or rags
✔ Rubber gloves and safety goggles
✔ Bucket of hot water
✔ Protective plastic sheeting (to cover nearby equipment)
For professional-level cleaning, services like Hygene Hood Cleaning use steam cleaners, eco-friendly solvents, and industrial vacuums.
Step-by-Step Guide: How to Clean a Kitchen Exhaust Fan
Step 1: Turn Off the Power
Before doing anything, ensure the power supply to the exhaust fan is completely off. This is vital for your safety and prevents accidental damage to the system.
Step 2: Dismantle the Fan Housing
Using your screwdriver, remove the protective cover or hood of the exhaust fan. Carefully place the screws in a safe spot. Be mindful of any attached electrical wiring or motor connections.
Step 3: Soak the Removable Parts
If your fan has removable blades or parts, soak them in hot water mixed with degreaser for at least 30–60 minutes. This helps loosen up the grease for easier scrubbing.
Use a non-abrasive brush to scrub away the softened grease, rinse thoroughly, and let them air dry.
Step 4: Clean the Fan Blades and Motor Housing
If the blades are non-removable:
✔ Use a damp cloth dipped in degreasing solution to wipe down the blades carefully
✔ Avoid applying too much pressure or moisture near the motor
✔ Use a toothbrush for hard-to-reach corners
If there’s a lot of build-up, repeat the degreasing and scrubbing process until clean.
Step 5: Clean the Exhaust Duct (if accessible)
While cleaning the fan, check the first few feet of the ductwork leading from the exhaust fan. Remove loose grease or debris using a long-handled brush and a vacuum if necessary. For full duct cleaning, it’s best to call in professionals.
Step 6: Dry and Reassemble the Unit
Ensure all components are completely dry before reassembly to prevent moisture damage. Reinstall the fan blades, cover, and screws. Restore the power supply and run the fan briefly to ensure it’s operating smoothly.
How Often Should You Clean Your Kitchen Exhaust Fan?
The cleaning frequency depends on your kitchen’s usage and cooking style:
| Kitchen Type | Cleaning Frequency |
| Light-duty kitchens | Every 3 months |
| Moderate-use kitchens | Monthly or bi-monthly |
| High-volume commercial kitchens | Every 2–4 weeks |
Hygene Hood Cleaning offers flexible cleaning schedules tailored to your kitchen’s needs, keeping your operations smooth and safe.
DIY vs Professional Cleaning: What’s Best?
While DIY maintenance can be effective for surface-level cleaning, deep-cleaning an exhaust fan and its connected systems requires professional expertise. Here’s why:
✅ Professionals Offer:
- Full compliance with AS 1851 standards
- Industrial-strength degreasing and steam cleaning
- Safe access to hard-to-reach ductwork and fan motors
- Proper disposal of hazardous grease and waste
- Peace of mind with inspection-ready reports
When it comes to safety and performance, it’s always worth trusting professionals like Hygene Hood Cleaning.
Benefits of a Clean Kitchen Exhaust Fan
Maintaining a clean exhaust fan doesn’t just tick a box for hygiene—it delivers real operational benefits:
✔ Better Airflow and Ventilation
Cleaner fans mean stronger suction power, improved airflow, and more efficient ventilation—especially critical in fast-paced kitchen environments.
✔ Energy Savings
Greasy fans force motors to work harder, consuming more energy. Regular cleaning helps reduce power consumption and extend the fan’s life.
✔ Fire Safety
Removing grease build-up significantly reduces fire hazards, protecting your kitchen, staff, and customers.
✔ Compliance and Insurance
Clean systems ensure your kitchen meets health, safety, and fire code regulations while keeping insurance policies valid.
