Commercial Kitchen Exhaust Hood Cleaning Checklist for Somerville, NJ
Running a commercial kitchen in Somerville demands an organized approach to ventilation hygiene. Grease-laden vapors from grills, fryers, and ovens collect on hood interiors, filters, ducts, and rooftop fans, creating fire hazards and airflow restrictions. To keep your operation safe and inspection-ready, follow a clear, repeatable checklist tailored to your equipment, menu, and volume. If you do not currently have a dependable partner for deep cleaning, consider establishing a routine with a trusted provider of kitchen exhaust hood cleaning so your team can focus on food quality and service while experts handle heavy-duty degreasing.
This guide presents a detailed, stepwise approach that fits Somerville’s diverse kitchens—from compact cafe lines to multi-hood restaurants. It covers planning, protection, degreasing, reassembly, verification, and documentation, along with tips for coordinating with landlords and navigating roof access in older buildings. Adapt these steps to your system layout and inspection requirements to ensure consistent results.
Step 1: Pre-Inspection and Planning
Begin with a visual review of hood interiors, baffle filters, duct access points, and rooftop fans. Note grease thickness, fan noise or vibration, missing or loose access panels, and any signs of water intrusion or prior leaks. Confirm electrical shutoffs and identify sensitive equipment that needs protective covering. Discuss your operating hours so service can be scheduled after close, minimizing disruption. If your building has restricted roof access, coordinate keys and safety procedures with property management in advance.
Set realistic expectations for the cleaning window, including cool-down time for hot equipment. Ensure adequate lighting for technicians and clear pathways for hoses and containment materials. A brief staff meeting before service helps everyone understand shutdown procedures and next-day start times.
Step 2: Workspace Protection and Safety
Cover cooking equipment, prep tables, and nearby surfaces to prevent splash and residue. Tape or otherwise secure coverings so they do not shift during rinsing. Confirm that fire suppression systems will not be inadvertently triggered during cleaning, and verify proper de-energizing of fans as needed. Establish runoff containment for both interior and rooftop areas, with approved disposal methods ready to prevent environmental release. Safety checks should include ladder inspection, tethering on rooftops, and communication tools for team coordination.
Post signage to inform any late-night staff or delivery drivers that cleaning is underway. Establish a boundary for non-essential personnel to keep the work zone clear. This streamlines the process, reduces accidental contamination of cleaned surfaces, and enhances technician safety.
Step 3: Filter Removal and Degreasing
Carefully remove baffle filters and place them in a soaking bath with an approved degreaser. Agitate as directed by the product guidance and rinse thoroughly with warm water to remove loosened grease. Inspect for warping or dents that can disrupt airflow and consider replacements if filters do not seat properly. Allow filters to dry completely before reinstallation. Meanwhile, technicians can begin scraping heavy deposits from hood interiors and accessible duct surfaces to speed chemical penetration later.
Filter care is also a daily or weekly task for your team between professional services. Establish an internal routine, record completion in a simple log, and train staff on proper handling to avoid accidental drops or bent frames. Clean filters support capture efficiency and delay deep system contamination.
Step 4: Hood, Plenum, and Duct Treatment
Once heavy deposits are removed, apply hot chemical degreasers to the hood interior, plenum, and accessible ducts, allowing proper dwell time. Avoid overspray on sensitive components, and use controlled-pressure rinse techniques to prevent leaks. In complex systems with long horizontal runs, ensure access panels are opened and edges resealed after cleaning. Technicians should verify that seals and fasteners remain intact to avoid future drips during cooking operations.
Inspect seams and joints for signs of collection points where grease tends to recongeal. Where duct insulation or gaskets are compromised, schedule repairs to prevent recurring residue and odors. Meticulous attention to these details improves long-term performance and reduces cleaning time at future visits.
Step 5: Rooftop Fan Disassembly and Cleaning
At the roof, disassemble the fan housing as appropriate, clean blades, shrouds, and drain paths, and check bearings and belts for wear. Remove grease trays or cups for cleaning and confirm proper reinstallation. Use containment to manage rinse water and prevent roof damage or environmental release. Missing hinges or hold-open devices should be addressed to enable safe, repeatable access on future services.
After cleaning, ensure fan rotation is correct and vibration is minimal. If there is persistent noise, investigate alignment and belt tension. Document any deficiencies that require a follow-up visit from an HVAC or hood service technician, especially if performance issues predate the cleaning.
Step 6: Detailing and Reassembly
Detail hood interiors and polish stainless surfaces to remove remaining film. Reinstall baffle filters, confirming that each seats snugly and in the correct orientation. Wipe surrounding walls and ceilings to reduce secondary residue that can migrate back toward the hood edge. Inside the kitchen, remove protective coverings methodically to avoid redepositing grease on freshly cleaned surfaces.
At the rooftop, verify all panels are secured and that any replaced fasteners meet manufacturer specifications. Confirm fan hinges lock properly in the open position to protect wiring and prevent damage during future services. A final visual inspection should show a uniform, clean metal finish inside the hood and clear pathways within the duct.
Step 7: Functional Checks
Restore power to fans and observe airflow. Check for unusual noises that might indicate belt slip, misalignment, or debris contact. Verify that makeup air engages and balances with exhaust volume. Inside the kitchen, confirm that capture is strong at typical cooking heights by observing smoke tests or steam movement during light production. If capture seems weak, look for obstructions, incorrectly installed filters, or damp baffles.
Confirm that lighting within the hood functions correctly and that lens covers are clean. Where condensation or drip patterns appear, reevaluate seal integrity and duct slopes. Early detection of these issues prevents downtime during peak service periods.
Step 8: Documentation and Sticker Placement
Request a written report summarizing the work performed, findings, corrective recommendations, and before-and-after photos. Ensure stickers are placed at the hood and rooftop fan, displaying service dates and next recommended service interval. Keep reports organized in a binder or digital folder accessible for inspectors. Somerville’s enforcement officials value clear records that show consistent maintenance aligned with your cooking volume.
Include an internal log for weekly filter cleaning and any observed airflow concerns. This supports your professional provider’s recommendations and helps you justify frequency decisions if schedules are adjusted based on seasonal volume.
Step 9: Mid-Cycle Care and Training
Between deep cleans, train staff on quick wipe-downs of visible surfaces at the end of each shift. Reinforce correct filter handling and safe degreaser use for routine maintenance. Encourage supervisors to report signs of reduced capture, such as smoke escaping the hood edge or odors lingering after closing. When mid-cycle issues arise, schedule a focused detail visit to restore performance without waiting for the full interval. Guidance from specialists in exhaust hood cleaning services can help calibrate frequency and improve day-to-day practices.
