Facts Restaurant Owners Need to Know about Commercial Kitchen Hood Cleaning

Opening and managing a restaurant successfully involves great attention to many factors, one of which is the cleaning and maintenance of kitchen hoods. Commercial kitchen exhaust hoods are vital in restaurants as they aid in getting rid of smoke, grease, and smells.

It is important to keep these systems clean for safety reasons, health benefits, efficiency in operation, and compliance with fire codes. This article presents some essential information about commercial kitchen hood cleaning that every restaurant owner should know.

Why a Commercial Kitchen Exhaust Hood is Necessary

Commercial kitchen exhaust hoods are designed to remove heat, smoke, grease, and particles from the air that accumulate during cooking. It also serves as an important part of fire prevention in the kitchen by trapping flammable substances such as oil before they can reach open flames or other hot surfaces.

The powerful exhaust fan in the hood draws air up into the ventilation ductwork, removing contaminants. Here are some of the key reasons an exhaust hood is so important:

  • Removes smoke and odors – Cooking inevitably produces smoke and odors, which will spread without a hood to contain them. This can make for an unpleasant dining experience. The hood captures these contaminants before they permeate the restaurant.
  • Manages kitchen heat – Commercial cooking equipment throws off intense heat. Without an exhaust hood, this can make the kitchen uncomfortably hot. The hood helps moderate kitchen temperature by removing hot air.
  • Prevents grease buildup – Grease particles emitted during the cooking process will eventually coat surfaces in the kitchen without an exhaust hood. Hence, it is dangerous for fire hazard.
  • Compliance with fire codes – Most places demand that commercial kitchen exhaust hoods found in restaurants meet all building and fire regulations. Kitchens without proper hoods may fail inspections.

Why Keeping the Exhaust System Clean is Critical?

These kitchen hoods are vital but they have to be kept up properly so that they remain in their topmost condition. Over time there will be a deposit of grease and other dirt in the hood, ductwork, and other parts of this system. Cleaning must be done regularly for the reasons below.

  • Reduces fire risk – Accumulation of grease greatly increases the chances of a kitchen fire. Regular system cleaning avoids this.
  • Ensures proper airflow – Accumulated grease in ducts obstructs airflow. This diminishes its ability to suck smoke and remove smells. Therefore, it becomes necessary for them to be cleaned.
  • Improves efficiency – An unclean exhaust system must work harder thus consuming more fuel and energy. Better efficiency comes through keeping it clean.
  • Prevents operational problems – Impacted matter can result in mechanical issues such as blocked ducts or fans with blades unable to move. Cleaning is therefore done so that such incidences are avoided.
  • Maintains kitchen cleanliness – When airflow within the exhaust hood is insufficient, oil and particles escape into other areas of your kitchen causing untidy conditions all over the place. For instance, when you clean them thoroughly, you will prevent greasy substances from finding their way out.
  • Provides healthier environment – With time, smoke, particulates as well as greasy residues contaminate the kitchen atmosphere. Indoor air quality cannot be improved without regular cleaning of duct systems like these ones in restaurants than any other area in a house.

How to Clean a Commercial Kitchen Exhaust Hood

Commercial kitchen exhaust hood cleaning involves cleaning all components of the system. Here is an overview of the process:

  • Remove and clean filters – Mesh grease filters trap large particles. These removable filters must be thoroughly cleaned. Soaking in a degreaser may be required to remove stubborn residues.
  • Wash out grease traps – Hoods contain grease traps and catch basins to collect grease. These must be scraped and washed out completely.
  • Clean fan blades – Exhaust fans accumulate sticky grease deposits that impact performance. Fan blades need to be scrubbed clean.
  • Degrease hood interior – All interior surfaces must be wiped down or degreased to remove clinging grease layers.
  • Clean ductwork – Ducts carry contaminants to the outside. Duct walls often have substantial grease buildup requiring cleaning.
  • Check fire suppression system – Hoods contain fire suppression systems that should be inspected and maintained.
  • Check hood operation – The cleaned system should be thoroughly checked to confirm proper performance.

Importance of Ductwork Cleaning

The ductwork carrying exhaust from the hood outside is prone to grease accumulation. Failure to clean ducts can lead to the following problems:

  • Decreased airflow – Grease narrows ducts, increasing resistance to airflow. This reduces exhaust efficiency.
  • Increased fire risk – Heavy grease deposits in ductwork are highly flammable. Neglected ducts are a fire hazard.
  • Odors – Grease breaks down over time, producing unpleasant odors that get drawn back into the kitchen.
  • Pest attraction – Grease residues attract roaches, rats, and other pests to duct interiors.
  • Hood performance issues – Severely restricted ducts overload the hood’s exhaust fan, shortening its life span.
  • Replacement need – If neglected long enough, clogged ductwork may need full replacement.

Professional Kitchen Exhaust Cleaning

The complex nature of industrial kitchen exhaust equipment makes it necessary for the use of professional cleaning services in almost all cases. The most reputable companies that clean commercial hoods have been servicing restaurant kitchens for many years. These employ specialized methods and tools when washing all parts of the system diligently as well as safely. Professionals can offer:

  • Proper cleaning methods – They use the most effective methods to remove stubborn deposits.
  • Skilled technicians – Their technicians are highly trained and experienced with restaurant hoods.
  • Specialized equipment – They have trucks equipped with high-power vacuum systems and other necessary equipment.
  • Compliance assurance – They ensure cleaning meets all codes and insurance requirements.
  • Documentation – They provide documentation showing cleaning was performed for compliance.

For restaurant owners, hiring professional exhaust hood cleaners gives assurance that this vital system is properly maintained for safety and efficiency. It’s a small investment that pays big dividends in the long run.


To give a restaurant the best results, it is necessary to clean the kitchen exhaust hood properly. If this essential maintenance step is ignored, there will be high chances of fire outbreaks, health risks as well as operational issues including breaking the law. Therefore, owners should know some important things about cleaning commercial kitchen hoods so that they can protect their investments and keep their kitchens safe for use.

It is also advisable that one hires qualified experts who are capable of doing thorough cleaning since this guarantees good outcomes; therefore, it is highly recommended.
