Quick answers
Kitchen Exhaust Cleaning Questions, Answered in Brief
The short version of each guide. Open a question for the answer, then read the full article for detail.
Many of our guides cite the NCC guide to kitchen local exhaust ventilation (F6D12) and the AIRAH Commercial Kitchen Exhaust Special Technical Group.
How Often Should a Commercial Kitchen Exhaust Be Cleaned?
Cleaning frequency depends on cooking volume, cooking style, operating hours, system condition and your maintenance obligations. High-volume frying, grilling and chargrilling kitchens usually need more frequent cleaning than low-volume kitchens.
How Much Does Commercial Kitchen Exhaust Cleaning Cost in Melbourne?
Price depends on the number of canopies, duct length and layout, fans, grease build-up, access and the agreed scope. A canopy-only clean and a complete system clean are different services with different prices.
What Does Commercial Kitchen Exhaust Cleaning Include?
A complete clean can cover the canopy, plenum, grease ducts, rooftop exhaust fan and grease filters. Cleaning only the visible canopy does not remove grease from the ducts and fan.
Commercial Kitchen Exhaust Cleaning Requirements in Victoria
In Victoria, building owners must maintain the essential safety measures listed for their building, usually in the occupancy permit or maintenance determination. AS 1851 is the Australian Standard for routine servicing of fire protection systems and equipment.
AS 1851 and Kitchen Exhaust Cleaning: What Melbourne Businesses Should Know
AS 1851 covers routine servicing of fire protection systems and equipment, with provisions relevant to certain kitchen exhaust maintenance activities. The AS 1668 series deals mainly with mechanical ventilation and smoke-control design and installation, not a cleaning schedule.
Commercial Kitchen Canopy Cleaning: The Complete Guide for Melbourne Kitchens
Canopy cleaning covers accessible canopy interiors, stainless steel surfaces, grease gutters, extraction openings and the plenum behind the filters. Grease behind the filters, in the plenum, is often heavier than what you can see.
How Grease Build-Up Turns a Kitchen Exhaust Into a Fire Risk
Grease residue inside range hoods and ducting is a recognised cause of restaurant fires. Fire can travel from the cooking line into the canopy and along ductwork, where it is hard to reach and extinguish.
How to Choose a Kitchen Exhaust Cleaning Company in Melbourne: 10 Questions to Ask
Ask exactly which components are included: canopy, plenum, ducts, fan and filters. Check insurance, safety arrangements for roof work and how chemicals are managed.

Grease Filter Exchange vs In-House Filter Cleaning: Which Suits Your Kitchen?
Grease filters capture part of the airborne grease before it reaches the ducts, so they need frequent care. In-house cleaning suits kitchens with light cooking, trained staff and suitable cleaning facilities.
7 Signs Your Restaurant Kitchen Exhaust Needs Cleaning
Visible grease, dripping, soiled filters and smoke lingering in the kitchen are common warning signs. Overdue cleaning records are a sign on their own, even if the canopy looks clean.
Restaurant Kitchen Exhaust Cleaning Checklist: Daily, Weekly and Monthly
Your team handles quick daily and weekly checks; specialists handle the canopy interior, plenum, ducts and fan. Filters need the most frequent attention in high-grease kitchens.
What Happens If You Don't Clean Your Kitchen Exhaust?
Grease keeps accumulating in the canopy, plenum, ducts and fan every time you cook. Accumulated grease is combustible and can help a fire spread through the exhaust system.
Kitchen Exhaust Maintenance Records: What to Keep and Why
Keep dates, the scope cleaned, before-and-after photos, inaccessible areas and recommendations for each clean. Add your in-house filter and gutter checks to the same file.
Commercial Kitchen Ventilation Requirements in Australia: NCC, AS 1668 and Food Standards
NCC clause F6D12 covers kitchen local exhaust ventilation for larger cooking setups. Under the Deemed-to-Satisfy Provisions, exhaust hoods must comply with AS 1668.1 and AS 1668.2.
Landlord or Tenant: Who Is Responsible for Kitchen Exhaust Cleaning in Victoria?
Responsibility depends on the lease, the building and who owns the exhaust equipment. Under Victoria’s Retail Leases Act, landlords must maintain landlord-owned plant and equipment; tenants must keep premises clean and in good order.
Kitchen Exhaust Cleaning and Insurance: What Insurers May Look For
Some insurance policies include conditions about kitchen exhaust inspection, cleaning and records. Published insurer guidance gives minimum cleaning examples and calls for more in heavy-use kitchens.
Why Is Grease Dripping From My Kitchen Canopy?
Common causes are full or blocked grease gutters, soiled or badly fitted filters, and heavy build-up in the plenum. Condensation mixing with grease can also run down canopy surfaces.
Kitchen Exhaust Duct Cleaning: How It Works and Why It Matters
Grease settles along horizontal runs, vertical risers, bends and transitions inside the ductwork. Ducts are cleaned through access openings using scraping, brushing and controlled degreasing.
Rooftop Exhaust Fan Cleaning and Maintenance: A Practical Guide
Grease builds up on fan blades, impellers and housings and can affect equipment condition. Cleaning removes grease; servicing covers mechanical and electrical checks by qualified personnel.
Why Is My Kitchen Exhaust Not Pulling Smoke? 8 Common Causes
Blocked filters and greasy ducts are common, easy-to-check causes of poor extraction. Fan faults, belts, airflow imbalance and design issues need a qualified technician.
Baffle Filters vs Mesh Filters: Choosing and Cleaning Commercial Grease Filters
Baffle filters use angled channels that make grease-laden air change direction; mesh filters trap grease in layers of mesh. Stainless steel baffle filters are widely used in commercial canopies and are designed to be cleaned and reused.
Kitchen Exhaust Cleaning for Fast Food and Takeaway Shops
Frying and grilling produce more grease-laden vapour than most other cooking. High-grease kitchens usually need more frequent filter, canopy and duct cleaning.
Kitchen Exhaust Cleaning for Aged Care, Hospitals and Schools
Institutional kitchens run to fixed meal times, so cleaning must be planned around service. Site access, induction and sign-in rules often apply in healthcare and education settings.
DIY vs Professional Kitchen Exhaust Cleaning
Staff can usually handle filters, gutters, drip trays and exterior wipe-downs. The plenum, ducts and rooftop fan need trained contractors with access and safety planning.
Kitchen Exhaust Glossary: Canopy, Plenum, Baffle, Riser and More
A kitchen exhaust system runs from the canopy, through filters and plenum, along the ducts to the exhaust fan. The plenum is the chamber behind the filters; it often holds more grease than the visible canopy.
