COMMERCIAL KITCHEN HOOD CLEANING GUIDE
How Often Should a Commercial Kitchen Hood Be Cleaned?
Commercial kitchen hood and exhaust systems should be inspected regularly
for grease buildup, with the appropriate frequency depending on the type
and volume of cooking being performed.
High-volume restaurants may require much more frequent attention than
seasonal or low-volume commercial kitchens. The condition of the hood,
filters, ductwork and exhaust fan should also be considered when
determining when professional cleaning is needed.
Quick Answer
NFPA 96 provides inspection intervals for grease buildup ranging from
monthly for systems serving solid-fuel cooking operations to annually
for certain low-volume cooking operations.
Important: These are inspection intervals. They should
not automatically be interpreted as a guarantee that every kitchen only
needs cleaning at that interval. Grease accumulation, cooking volume,
equipment, fuel type and applicable requirements can mean cleaning is
needed sooner.
NFPA 96
Commercial Kitchen Exhaust Inspection Frequency
NFPA 96 establishes different inspection frequencies based on the type
and volume of cooking operation.
Typical Inspection Schedule
Solid-fuel cooking operations: Monthly
High-volume cooking operations: Quarterly
Moderate-volume cooking operations: Semiannually
Low-volume cooking operations: Annually
High-volume operations can include kitchens with heavy or continuous
cooking activity such as 24-hour cooking, charbroiling or wok cooking.
Lower-volume operations can include certain churches, seasonal
businesses and similar facilities.
These intervals concern inspection for grease buildup. The actual need
for cleaning should be based on the condition of the exhaust system and
applicable requirements.
IMPORTANT DISTINCTION
Inspection Frequency vs. Cleaning Frequency
Inspection
An inspection determines the amount and condition of grease buildup
within the commercial kitchen exhaust system.
Cleaning
Cleaning removes accumulated grease and contamination from the
accessible components of the exhaust system when cleaning is
required.
This distinction matters. A restaurant should not assume that simply
reaching a calendar date means every exhaust system is in exactly the
same condition.
Cooking volume, food type, equipment, previous cleaning quality and the
rate of grease accumulation can all affect the condition of the system.
HIGH-VOLUME KITCHENS
Why Some Restaurants Need More Frequent Attention
A busy commercial kitchen can produce significant quantities of
grease-laden vapour. Over time, deposits can accumulate throughout the
exhaust path rather than remaining only on the visible hood.
Kitchens using charbroilers, woks, fryers or other equipment that
generates substantial grease may therefore need closer monitoring than
lower-volume kitchens.
Restaurants operating for long hours or producing large numbers of meals
should pay particular attention to the condition of the entire exhaust
system.
THE COMPLETE SYSTEM
Hood Cleaning Is More Than Cleaning the Visible Hood
A commercial kitchen exhaust system can contain several components that
require inspection and maintenance.
Kitchen Hood
The canopy and surrounding hood surfaces collect grease generated
during cooking.
Grease Filters
Filters are an important part of capturing grease before it travels
farther into the exhaust system.
Exhaust Ductwork
Grease can accumulate beyond the visible hood and within the
exhaust duct system.
Exhaust Fan
Fan blades, housing and surrounding components can also accumulate
grease and require attention.

WARNING SIGNS
Signs Your Kitchen May Need Cleaning Sooner
Visible Grease
Noticeable grease accumulation around the hood, filters or accessible
exhaust components deserves attention.
Heavy Cooking Volume
Increased operating hours or meal volume can increase the rate at
which grease accumulates.
Changes in the Exhaust System
Unusual exhaust performance or visibly contaminated components can
justify having the system professionally assessed.
Unknown Service History
If you do not know when the exhaust system was last professionally
cleaned, arranging an inspection can establish a useful baseline.

Cooking Equipment
What equipment and cooking methods are being used?
Grease Accumulation
How quickly is grease accumulating throughout the system?
Previous Service
When was the system last inspected and professionally cleaned?
Local Requirements
What requirements apply to the facility and jurisdiction?
Professional Assessment
A qualified professional can assess the condition of the exhaust
system and help determine appropriate next steps.
FREQUENTLY ASKED QUESTIONS
Commercial Hood Cleaning Frequency FAQs
How often should a restaurant hood be cleaned?
There is no single cleaning interval that accurately describes every
restaurant. Cooking volume, equipment, fuel type, grease accumulation and
applicable requirements should be considered. NFPA 96 establishes
inspection frequencies for grease buildup based on the type and volume of
cooking operation.
Do busy restaurants need more frequent inspections?
Yes. NFPA 96 identifies quarterly inspection for high-volume cooking
operations and monthly inspection for systems serving solid-fuel cooking
operations.
Does hood cleaning include the duct and exhaust fan?
The commercial kitchen exhaust path extends beyond the visible hood.
Depending on the service required, professional cleaning can involve
accessible hood, duct and exhaust-fan components.
What if I do not know when my hood was last cleaned?
Consider arranging an assessment rather than guessing. A professional can
evaluate the system’s condition and help determine whether cleaning is
required.
