While the provided reference focuses on cleaning the extractor fan itself, cleaning the ducting requires a different approach as it's less about surface cleaning and more about removing accumulated dust, grease, and debris within the ventilation system. Here's how to clean extractor fan ducting:
Steps to Clean Extractor Fan Ducting:
-
Preparation & Safety:
- Turn off the power to the extractor fan at the breaker box to ensure safety.
- Wear appropriate safety gear, including a dust mask and gloves.
- Cover nearby surfaces to protect them from dust and debris.
-
Access the Ducting:
- Determine how accessible your ducting is. Some ducting is easily removable, while others are fixed.
- If possible, detach sections of the ducting for easier cleaning. This is usually held together by clamps or screws.
-
Cleaning Methods:
- Vacuuming: Use a vacuum cleaner with a hose attachment to suck out loose dust and debris from inside the ducting. This is effective for surface-level dust.
- Brush Cleaning: Use a long-handled brush, such as a duct cleaning brush or even a flexible chimney sweep brush, to dislodge stubborn buildup. Rotate the brush as you push it through the duct.
- Compressed Air: Use compressed air to blow out remaining dust and debris. Be sure to direct the airflow safely and wear eye protection.
-
Dealing with Grease Buildup:
- If grease buildup is present (common in kitchen extractor fans), use a degreasing solution specifically designed for ventilation systems.
- Apply the degreaser according to the manufacturer's instructions. You may need to let it soak for a period to loosen the grease.
- After applying the degreaser, use the brush and vacuum to remove the loosened grease.
- Wipe down the inside of the ducting with a damp cloth.
-
Reassembly & Testing:
- Once all sections are clean and dry, reassemble the ducting, ensuring all connections are secure.
- Turn the power back on to the extractor fan and test its operation.
Important Considerations:
- Frequency: Clean your extractor fan ducting at least once a year, or more frequently if you notice reduced airflow or a build-up of grease.
- Duct Material: Be mindful of the ducting material (e.g., flexible aluminum, rigid metal, plastic). Use cleaning methods appropriate for the material to avoid damage.
- Professional Cleaning: For complex ducting systems or if you are uncomfortable performing the cleaning yourself, consider hiring a professional duct cleaning service.
- Inspection: While cleaning, inspect the ducting for any damage, such as tears or leaks. Repair or replace damaged sections to ensure proper ventilation.
By following these steps, you can effectively clean your extractor fan ducting, improving its efficiency and preventing potential fire hazards.
