A dirty extraction system in your restaurant kitchen is more than just an eyesore—it’s a fire hazard, reduces ventilation efficiency, and can lead to TR19 non-compliance. If grease and debris aren’t regularly cleaned, your system could fail inspections, void insurance policies, or even put your staff and customers at risk.
In this guide, we’ll cover:
✅ Why cleaning your extraction fan is crucial
✅ How often you should clean it (based on TR19 guidelines)
✅ Step-by-step cleaning process
✅ When to call in professional TR19-certified cleaners
Why Is Cleaning Your Restaurant’s Extraction Fan Important?
Your extraction fan plays a key role in removing heat, smoke, and airborne grease from your kitchen. When it becomes clogged with grease and debris, several problems arise:
🔥 Increased fire risk – Grease buildup can ignite, leading to devastating kitchen fires.
🚫 TR19 non-compliance – Failure to clean your system regularly can result in penalties or insurance claim denials.
💨 Reduced airflow – A blocked extraction system struggles to remove heat and smoke, making the kitchen uncomfortable.
💰 Higher energy bills – A dirty fan motor has to work harder, consuming more electricity.
How Often Should You Clean Your Extraction Fan? (TR19 Guidelines)
According to TR19 grease regulations, cleaning frequency depends on how often your kitchen operates:
| Usage Level | Hours per Day | Recommended Cleaning Frequency |
|---|---|---|
| Heavy use | 12+ hours/day | Every 3 months |
| Moderate use | 6–12 hours/day | Every 6 months |
| Light use | 2–6 hours/day | Every 12 months |

Step-by-Step Guide: How to Clean a Restaurant Extraction Fan
1️⃣ Turn Off Power & Prepare for Cleaning
Before starting, turn off the fan and disconnect the power supply to avoid accidents. Cover surrounding kitchen equipment to protect it from grease and chemical splashes.
2️⃣ Remove the Fan Cover & Blades
Most restaurant extraction fans have removable blades and covers. Unscrew these components and set them aside for cleaning.
3️⃣ Degrease the Fan Blades
- Soak the blades in warm water mixed with a degreasing solution.
- Scrub thoroughly using a stiff brush to remove grease buildup.
- For heavy grease deposits, use a TR19-compliant degreaser.
4️⃣ Clean the Fan Motor & Housing
- Wipe down the motor with a dry, lint-free cloth (avoid using excessive water).
- Use a vacuum or compressed air to remove dust buildup inside the housing.
5️⃣ Inspect & Clean Ductwork
- Grease can accumulate inside the ductwork, posing a fire hazard.
- If you notice excessive buildup, it’s best to hire professional TR19 kitchen extraction cleaners.
6️⃣ Reassemble & Test the Fan
Once all components are dry, reassemble the fan, reconnect the power, and test for proper airflow.
When Should You Call Professional TR19 Cleaners?
While basic cleaning can be done in-house, deep cleaning and compliance checks should always be handled by professionals. You should hire a TR19-certified cleaning company if:
✅ Grease buildup is too heavy to remove manually
✅ The ductwork needs internal cleaning
✅ You require a TR19 compliance certificate for insurance purposes
