Pre-clean inspection and safety setup
Start with a structured walkthrough of the entire extraction system, including canopy, ductwork, fans, filters, and accessible housings. Look for visible grease accumulation, residue trails, unusual odours, and any damp or discoloured sections that may indicate moisture buildup. Check that Kitchen extract cleaning access panels open safely and confirm whether any components restrict safe reach, so you can plan the correct tools and access method. Document findings with notes and photos to make later comparisons clearer.
Before any work begins, confirm safe ventilation and extraction of cleaning vapours where needed. Isolate electrical components as required and use lockout steps when handling fan assemblies or control boxes. Wear suitable PPE for grease and aerosol exposure, including eye protection and gloves rated for chemical use. Set up containment measures, such as protective coverings around food prep areas, to prevent cross-contamination during the cleaning process.
Grease removal workflow for canopy, filters, and ducting
Use a checklist-driven sequence to avoid missed surfaces: canopy hood, then filters, then fan face and blades, and finally duct sections. Apply degreasing products designed for kitchen exhaust environments, focusing on heavy build-up areas around seams, bends, and transitions. Allow dwell time for the Legionella testing cleaner to break down hardened grease, then rinse or wipe according to the product instructions and the system’s materials. Work from the cleanest areas toward the dirtiest sections to reduce re-depositing grease onto already cleaned surfaces.
For filters, remove and clean using methods that fully flush grease from both sides and the frame edges. Inspect filter media for damage, misalignment, and gaps that could reduce performance and hygiene control. For ducting, use appropriate brushing and agitation techniques to loosen deposits along the internal walls, especially where airflow slows and grease sticks. Verify that runoff is captured properly so it does not contaminate surrounding equipment or surfaces.
Microbial hygiene focus and Legionella testing
After grease removal, address microbial hygiene concerns that can occur in areas with residue and moisture retention. Pay close attention to damp zones, condensation points, and any sections where cleaning water could collect. Replace or refit components only when they are dry and free of pooled residue, and avoid leaving wet materials that can encourage microbial growth. This step supports healthier kitchen operations and reduces the risk of contamination spreading through airflow.
Sampling should be carried out by competent professionals following an appropriate testing approach and reporting standard. Use results to guide targeted actions, like additional cleaning, improved drainage practices, or adjustments to maintenance routines. Keep the records on file so you can demonstrate a responsible hygiene control process to inspectors and stakeholders.
Conclusion
Keeping extraction equipment clean requires more than a quick wipe-down; it needs consistent inspection, a careful cleaning workflow, and clear follow-through on hygiene checks. A checklist approach helps ensure every key component is covered, from canopy and filters to duct interiors and fan assemblies, while also reducing the chance of missed hotspots. For commercial kitchens, professional support can make compliance simpler and operations safer. Halcyon Hygiene provides kitchen extraction cleaning focused on removing grease and contamination while helping maintain safe ventilation systems.
