Introduction
New Jersey restaurants operate in a fast-paced environment where safety, compliance, and consistent food quality all depend on a reliable kitchen exhaust system. A practical, detailed cleaning checklist is your best tool for keeping grease under control and preventing fire hazards. This guide provides a comprehensive, New Jersey–specific checklist you can put to work today. If you need support beyond your in-house plan, professional kitchen hood cleaning can help you meet code, pass inspections, and keep operations running smoothly.
Beyond compliance, maintaining a clean exhaust hood reduces odors, improves indoor air quality, and extends the lifespan of fans, ducts, and make-up air units. By following the steps below, you will understand precisely what to do daily, weekly, monthly, and quarterly, and how to prepare for third-party service when it is time for a deep clean under NFPA 96–aligned standards. The result is safer staff, better performance from your equipment, and a documented program that satisfies inspectors.
Why a Checklist Matters in New Jersey
New Jersey municipalities take commercial kitchen safety seriously, and inspectors often look for evidence that your exhaust system is maintained on a schedule appropriate to your volume and fuel type. Shore towns, college communities, and busy turnpike-adjacent corridors see heavy seasonal spikes in traffic, which drive higher grease accumulation. A living checklist keeps your team on task even during rushes, reduces the risk of missed steps when staff turn over, and standardizes procedures so you can train quickly. It also gives you the written documentation inspectors expect to see when they visit, especially after any ventilation-related incident.
Core Daily Tasks
Start each shift by verifying that hood filters are seated correctly and visibly free of heavy grease. Wipe exterior hood surfaces and the perimeter lip at least once per shift, always using degreasers approved for stainless steel. Inspect the light lens covers for buildup, and check that they are intact and secure. Confirm that the make-up air is running properly so your hood can capture smoke and steam efficiently. When the last ticket closes, remove baffle filters for a sink wash or run them through the dishwasher if the manufacturer allows it, then dry and reinstall. Record all daily actions in a log, noting any abnormal odors, smoke spillage, or audible fan issues.
Weekly and Biweekly Essentials
Weekly, perform a more deliberate wipe-down on the inside edges and undersides of the hood canopy where splatter tends to collect. Inspect the filter frames for warping, and make sure grease cups or trays are emptied and cleaned. Examine accessible duct openings, if any, for signs of excessive buildup. Look over the fan belt tension and listen for vibration that might indicate misalignment or bearing wear. Check for corrosion or loose fasteners on the hood body, and ensure all access panels that your contractor uses remain unobstructed. For high-volume or solid fuel operations, move some of these checks to a biweekly cadence.
Monthly Tasks for Performance and Safety
Each month, confirm that the hood lights use the correct, enclosed style for grease environments and that gaskets or seals on lens covers are in good shape. Test the interlock between the exhaust fan and cooking appliances, if your system requires one, by turning equipment on and ensuring the fan activates as expected. Review your cooking menu and volumes to see if grease production has changed, and adjust your cleaning frequency accordingly. This is also the time to step back and observe capture and containment: Is smoke rolling out of the hood when you sauté or grill? Are there drafts created by open doors or ceiling diffusers that interfere with capture? Note any deficiencies and plan mitigations.
Quarterly Deep-Clean Coordination
In many New Jersey restaurants, quarterly or semiannual deep cleaning of the hoods, ducts, and fans is the norm, adjusted for volume and fuel type. Ahead of your scheduled service, make sure roof access is clear, keys or codes are available, and any rooftop protection needed for grease run-off is in place. Confirm that staff know the service window and have prepped the line by covering sensitive surfaces, cooling appliances, and securing chemicals. Update your vendor with any changes to equipment lineups or hood sections so they arrive with the right access and nozzle configurations, if applicable for fire systems. After the deep clean, collect before-and-after photos, the written service report, and the compliance sticker or tag.
Pre-Clean Safety Checks
Before any internal staff clean, lock out or power down equipment as appropriate to avoid accidental ignition, and verify that hot surfaces have cooled sufficiently. Use approved degreasers, not improvised solutions, since household cleaners can be flammable or corrosive to stainless steel. Provide gloves and eye protection for anyone handling degreaser or hot water. Ensure that floor mats and anti-slip measures are in place because overspray and rinse water can make floors slick. Keep a Class K fire extinguisher nearby and verify your automatic fire suppression system’s inspection tag is current.
During-Clean Techniques
Work from the cleaner areas toward the greasier ones to prevent spreading contamination. For daily and weekly staff work, a warm-water rinse followed by an alkaline degreaser can speed removal. Agitate stubborn areas with non-scratching pads. Avoid saturating electrical components or light fixtures; use damp cloths around sensitive areas. When you clean or replace baffle filters, make sure the arrows indicating airflow are oriented correctly. Recheck drip trays to ensure they are empty and seated before service resumes. Where accessible, wipe the inner lip and lower duct area without reaching beyond what is safe and allowed for in-house staff.
Post-Clean Verification and Documentation
After any cleaning session, visually inspect for streaks, heavy residue patches, or missed corners. Turn on the fan and look for improved capture, particularly over high-output appliances like charbroilers. Make sure filters are secure and not rattling. Dry any moisture before the line heats up. Log the date, time, staff involved, and observations in your maintenance records. Over time, these notes help you spot trends—such as a particular station producing more residue than expected—that may require changes to equipment layout or menu techniques.
Midway Reminder: When to Call in Professionals
While a disciplined checklist covers daily and weekly needs, heavy grease inside ducts and fans is dangerous and cannot be handled safely without the right tools and access. If your staff observe recurring smoke rollouts, strong grease odors, or reduced airflow, it’s time to schedule expert support. Mid-cycle service can be valuable after peak seasons or special events. Trusted providers bring certified technicians, specialized degreasers, and compliant methods for full-system cleaning. If you need expert help, consider professional kitchen hood cleaning to restore performance and document compliance.
Common Pitfalls to Avoid
One of the most frequent problems is assuming dishwasher runs alone are sufficient for baffle filters; they usually need pre-scrubbing and proper drying. Another pitfall is neglecting the fan on the roof. If grease collects at the fan housing or in the discharge area, runoff can damage roofing materials and create slip hazards. Forgetting to reinstall filters properly can create air bypass, reducing capture and increasing fire risk. Skipping logs also creates headaches during inspections because you cannot demonstrate consistent maintenance. Finally, avoid using abrasive tools that scar stainless steel; scratches hold grease and make future cleaning harder.
Seasonal Considerations in New Jersey
During humid Jersey Shore summers, moisture combines with grease to form a sticky film that demands more frequent wipe-downs. In winter, doors and windows stay closed, which affects building pressure; if your dining room air balance shifts, smoke might drift where it never did before. Around holidays and local festivals, expect surges in volume and plan extra filter cycles. For restaurants near universities, semester starts can overwhelm staffing—your checklist becomes even more important for maintaining standards amid new team members. Use seasonal trend notes in your log to recalibrate deep-clean frequency.
Training and Culture
A checklist is only as effective as the people using it. Build short, station-level training sessions into pre-shifts, and rotate responsibilities so everyone understands the essentials of exhaust maintenance. Keep laminated copies of the checklist at each hood section. Encourage staff to report noise, vibration, or visible smoke promptly. Recognize team members who catch issues early, and audit compliance weekly. When your team internalizes the reasons behind each step—safety, clean air, consistent cooking—the checklist becomes a habit rather than a chore.
Inspection Readiness and Recordkeeping
Whether your local authority is the health department, fire marshal, or a third-party inspector, being inspection-ready reduces stress. Keep a binder or digital folder with daily, weekly, and monthly logs; deep-clean reports; photographs; and any corrective actions taken. Include equipment lists and model numbers for hoods, fans, and suppression systems. If you make menu changes that significantly increase grease output, document the date and corresponding adjustments to your schedule. During inspections, present your records confidently and walk the inspector through your process. This transparency builds trust and often shortens the visit.
Quality Control and Performance Checks
In addition to cleanliness, use simple performance checks to confirm capture. Place a light strip of tissue at hood edges during operation; if it pulls steadily toward the filters, airflow is likely sufficient. Observe smoke behavior during a stress test—searing steaks or frying multiple batches at once. If smoke escapes, check for obstructions, verify that makeup air is functioning, and ensure filters are not clogged. Small performance tests, recorded monthly, provide early warnings that your system needs service beyond the routine wipes and filter cycles.
