Kitchen hoods are often the most overlooked appliance in your kitchen. However, just like any other kitchen appliance that needs proper cleaning and maintenance, kitchen hoods need the same. They need thorough cleaning once in a while to keep them working at maximum performance. Cleaning your kitchen hoods will also extend the life of these appliances.
You can cook anything without having to worry about the smoke and odors in your kitchen because of your kitchen hoods. They pull away from these unwanted particles so you can have a cooler kitchen environment and a safe kitchen area. In return, kitchen hoods can accumulate grease which is not good for your kitchen. If your hoods are clogged with grease and other grime, there can be a risk of fire hazard. Also, the air inside the kitchen will be polluted which can cause health problems like carbon monoxide poisoning.
To avoid this, you need to have your kitchen hoods frequently cleaned by professional cleaning experts. NFPA-96 Standard states the minimum requirements for the cleaning process of your kitchen hoods. It involves everything from the hoods, filters, fans, and all associated horizontal and vertical ductworks.
How often do you need kitchen hood cleaning?
Kitchen hood cleaning requirements and best practices are stated in NFPA-96 Standard section 11.4, including the frequency of cleaning for all the types of commercial kitchens:
- Monthly- These are for systems serving solid fuel cooking operations
- Quarterly- These are for systems serving high-volume operations, such as 24-hour cooking, charbroiling, wok cooking, etc.
- Semi-annually- These are for systems serving moderate-volume cooking operations
- Annually- These are for systems serving low-volume cooking operations, such as churches, day camps, seasonal business or senior centers.
Who are qualified for kitchen hood cleaning jobs?
The governing standard provides also the qualification of the people who will perform the job. It states that the entire exhaust system shall be inspected for grease build up by a properly trained, qualified and certified person(s) acceptable to the authority having jurisdiction. Kitchen exhaust cleaning is not just done by anybody. While restaurant employees are expected to clean the exterior surfaces of exhaust hoods as part of the normal hood cleaning procedures, thorough cleaning of the system is to be carried out by certified kitchen exhaust cleaning professionals.
The scope of the work should include:
- Disassembly, cleaning and degreasing hoods, including hood filter tracts, grease troughs, and removable grease cups
- Removal of the roof and/or wall mounted fans from ductwork to degrease the base, shroud, and blades
- Inspecting exhaust fans for loose or worn out fan belts
- Cleaning and degreasing all hood filters, hood parts and accessories, and replacing if necessary
- Cleaning all accessible parts of ductwork from exhaust fans to each individual hood
- Applying food-safe polish to stainless steel ductwork
- Thoroughly cleaning all affected areas (remove plastic, mop, remove any debris, etc.)
- Providing a complete, detailed written report of all work performed, and deficiencies in the exhaust system, and recommendations for addressing any problems
- Attaching a certificate showing the company name, the person performing the work and date of cleaning to each hood cleaned
In other words, you need professional cleaning experts to ensure a worry-free cleaning process. Hiring them will help you save time, energy and money in the process. They are experts in the field of kitchen hood cleaning so they can guarantee you a thorough cleaning of your kitchen hoods.
Why are access doors important?
The most effective and efficient way of cleaning the kitchen hoods is by accessing as much of the whole system as possible. In order to reach parts of the system including horizontal and vertical ductworks, openings must be installed to clean these areas.
NFPA-96 sections 7.4.1 and 7.4.2 recommend the installation of openings large enough to permit thorough cleaning at a minimum of every 12 feet of horizontal ductworks and on every floor of vertical ductwork. It is also necessary to have access doors at every change of direction.
Kitchen hood cleaning will help you stay in compliance with the governing regulation and it will protect your investment in terms of the structure. It will also bring safety to you and your loved ones. Many people are willing to invest in good kitchen hood cleaning operators because they know the benefits it can give to them.
