What is a kitchen exhaust cleaning checklist?

A kitchen exhaust cleaning checklist is a written, repeatable sequence covering hoods, baffle filters, plenum, ducts, exhaust fans, and roof protection. It defines surfaces, chemicals, methods, safety controls, and proof-of-service, so any trained staffer—or your cleaning vendor—can execute consistently.

In our experience serving restaurants and institutional kitchens, checklists prevent blind spots. Teams rotate. Shifts run late. Without a clear list, grease hides in seams and transitions where heat is highest. A durable, laminated list near the line helps everyone remember critical steps between pro services.

For deeper context on system components and why each matters, see our internal primer on kitchen exhaust cleaning and the practical hood and vent cleaning guide.

Why the checklist matters for safety and compliance

Grease in hoods, ducts, and fans is a primary restaurant fire hazard. A checklist lowers ignition risk, supports NFPA 96 alignment, improves capture efficiency, and provides documentation that insurers and inspectors expect.

Here’s why operators across All Over Ontario rely on a formal list:

• Fire hazard reduction: Grease ignites at typical fryer and broiler temperatures. Removing buildup interrupts that fuel source.
• Airflow and comfort: Clean filters and ducts pull smoke, steam, and heat away from cooks, stabilizing temperature and odor control.
• Compliance confidence: Inspectors look for access panels, clean signatures on fans, and evidence of hinge kits and rooftop protection.
• Equipment longevity: Fans run cooler with balanced blades and tensioned belts, reducing wear.
• Shift-ready operations: Less smoke and fewer nuisance alarms mean smoother service and happier guests.

For background on code expectations in plain terms, review our overview of fire code requirements for kitchen exhaust and this NFPA 96–focused resource on cleaning schedules.

How the exhaust system works (and what to clean)

Your hood captures heat and vapors at the source, baffle filters remove larger grease droplets, ducts carry the airstream, and the rooftop fan discharges it safely. Cleaning focuses on every surface that grease touches—from hood seams to the fan housing and roof containment.

Key components to understand and include in your plan:

• Canopy hood and plenum: Hot vapors rise; grease condenses on metal. Degrease seams, rivets, and the plenum cavity.
• Baffle filters: These collect droplets. Clean or exchange routinely to maintain airflow.
• Vertical and horizontal ducts: Grease adheres at elbows and transitions first; ensure access panels allow full scrape and rinse.
• Exhaust fan assembly: Blades, housing, and drains trap residue. Hinges, hold-open, and a disconnect switch enable safe service.
• Rooftop protection: Use grease containment to protect membranes; saturated pads must be replaced.

The kitchen exhaust cleaning checklist (step-by-step)

Follow these steps from line shutdown to final photos. This sequence standardizes prep, degreasing, rinse, reassembly, and documentation—so shifts start clean, fans run smooth, and inspectors see clear evidence.

1. Prep the line: Power down cooking equipment, cover appliances, and place wet-floor signage. Set up plastic sheeting and drip trays under the hood.
2. Verify safety controls: Confirm the fan disconnect and a hold-open hinge are present. Lockout/tagout as needed.
3. Remove baffle filters: Place in a soak tank with a biodegradable degreaser. Rinse and inspect for damage; swap if bent or broken.
4. Degrease the hood and plenum: Apply food-safe alkaline degreaser. Scrape carbonized sections, then rinse with low-pressure warm water.
5. Open access panels: Expose horizontal and vertical duct runs. Scrape heavy deposits and follow with heated chemical application.
6. Service the exhaust fan: Open hinged fan. Scrape and degrease blades, housing, and drain. Check belt tension and bearing play.
7. Protect the roof: Replace saturated containment pads. Ensure no chemical runoff enters drains.
8. Rinse and neutralize: Rinse all treated surfaces, neutralize as required, and wipe dry accessible areas.
9. Reassemble and test: Reinstall clean filters. Remove sheeting. Restore power and verify airflow and abnormal noise.
10. Document proof: Capture before/after photos at the hood, each duct access, and the fan. Log date, staff/vendor, and any repairs needed.

Many operators also align this list with a filter exchange program to keep static pressure low between deep cleans.

Types of cleaning methods and schedules

Use manual scraping for heavy deposits, hot-water rinse for residue, and chemical degreasers for film. Schedule service by cooking volume: high-volume fryers and charbroilers need more frequent cleaning than light-duty, low-grease operations.

Common methods

• Hand scraping: Fast removal of thick grease; always follow with degreaser and rinse.
• Heated chemical degreasing: Biodegradable alkaline solutions break down film on metal surfaces.
• Hot-water rinse: Low-pressure rinse carries loosened residue to containment; avoid blasting debris deeper into ducts.
• Steam-assisted cleaning: Helpful on complex geometries; verify compatibility with roofing materials.

Scheduling guidance

• High-volume cooking: Fryers, woks, and charbroilers typically require the most frequent service.
• Moderate use: Standard line service with grills and ovens lands in the midrange.
• Low-grease operations: Light-duty, minimal-grease cooking can extend intervals if inspections show low buildup.

Best practices from NFPA 96–aligned pros

Standardize access, protect the roof, verify fan hinges and disconnects, capture photos at every stage, and log belt tension and bearing condition. Pair deep cleans with filter exchanges to keep airflow high and smoke low between services.

• Access first: Ensure every elbow and transition has an access panel sized for scraping tools.
• Roof protection: Use grease containment and replace pads when saturated to protect membranes.
• Hinge and hold-open: Hinged fans prevent wiring strain and allow safe cleaning; hold-open devices secure the lid.
• Mechanical checks: Log belt tension, set-screw security, and abnormal noise or vibration during every visit.
• Evidence trail: Keep dated before/after photos and signed certificates. Inspectors expect clear proof of work.
• Coordination: Schedule during low-volume windows or overnight to avoid service disruption.

Local considerations for All Over Ontario

• Plan roof work around wind and precipitation common in the region; wet membranes are slippery and affect containment setup.
• Seasonal menus change grease load. After festival or holiday spikes, advance a deep clean to keep ducts safe.
• Coordinate overnight access to malls and food courts; security protocols can add time for equipment staging.

Tools and resources you’ll need

Successful exhaust cleaning needs access tools, biodegradable degreasers, hot-water rinse capability, roof containment, PPE, and a simple documentation kit. Stock spares for belts and filters so you can fix issues before the next rush.

Tools

• Access and containment: Hinges, hold-open devices, access panels, plastic sheeting, drip trays, roof pads, and absorbents.
• Cleaning gear: Scrapers, brushes, heated sprayers, and low-pressure rinse wands.
• Safety: Gloves, goggles, cut-resistant sleeves, non-slip footwear, and harnesses for rooftop work.
• Mechanical spares: Fan belts (matched size), set screws, and hinge pins.
• Documentation: Camera/phone, service log, and a laminated checklist by station.

Resources

• Service guidance: Review our NFPA 96–aligned cleaning schedule summary.
• Operations playbooks: Pair with our hood cleaning guide to train new staff.
• System health: Use the fan maintenance guide after every deep clean.
