Kitchen exhaust cleaning (commonly known as hood cleaning) is very important for your commercial kitchen maintenance since it removes grease buildup inside the hoods, fans, ducts, and vents of exhaust systems.

Left uncleaned, grease can accumulate gradually on your kitchen exhaust systems until it eventually becomes an extreme fire hazard. Therefore, it’s important to have a professional inspect your exhaust systems regularly depending on the usage to check the amount of grease that has accumulated so that you can schedule cleaning if necessary.

Ensure to clean your kitchen hood regularly

You should ensure that your kitchen hood is cleaned regularly to maintain a hygienic and safe environment. You will reduce the risk of fire in your restaurant and avoid breaking health and safety compliance regulations if you keep your kitchen hood and exhaust system free from dirt and grease.

The NEPA’ (National Fire Protection Association) reports for the past couple of years have shown that cooking oils, grease, and food cause 43% of restaurant fires.

While keeping a commercial kitchen clean and tidy is an essential part of running a restaurant, it is not an easy job. You and your employees can handle some tasks but it is best to hire a professional for your hood cleaning.

Our professional restaurant hood cleaning services Northern IL guarantee complete and effective removal of grease buildup in the fans and exhaust systems to avoid a fire hazard to your restaurant.

Hood Cleaning Processes

The first step in hood cleaning is to scrap the exhaust system clean (but this step might not be necessary for an exhaust system properly maintained with safe chemicals and hot water). Then food-safe caustic chemicals and hot water pressure-washing – if possible – are used to wash clean the system and the dissolved grease and water are safely collected.

Our commercial kitchen exhaust system cleaning follows NFPA guidelines. The type of food being cooked and the amount of grease-laden vapors drawn through the hood plenum determine the frequency of cleaning.

For example, a restaurant kitchen with fewer cooking activities may require less exhaust hood cleaning while a busy restaurant kitchen that does heavy cooking involving fries would require more frequent cleaning. Typically, the cleaning can be done monthly, every two months, quarterly, semiannually, and annually.

Use of Caustic Chemicals

Caustic chemicals are used for kitchen exhaust cleaning to break down the grease. Next, the residue will be rinsed away with hot water. Generally, a garden-type sprayer, downstream injection through a pressure washer or a chemical foamer can be used to apply chemicals.

A professional applies the chemicals on the surface of grease and leaves it to dwell for some time, before spraying hot water on the surface to wash it off. In some extreme situations, the cleaners may have to scrape the contaminated surfaces first to remove excess grease buildup before applying chemicals and rinsing with hot water.

Hot Water Pressure Washing 

There are machines for restaurant hood cleaning that can both boil and apply hot water under pressures up to 14,000 kPa. The common method of preparation involves clipping heavy-duty tarps to the hoods first and then angling them to direct the run-off into plastic garbage cans.

The cans are successively emptied as they collect the run-off and the contents are disposed of properly. Emptying the grease into the local drains can cause clogging, and therefore, it should be removed instead.

Improper horizontal duct cleaning can cause some problems, including excessive grease buildup in inaccessible ductwork. Steam cleaners tend to move the grease further into the ductwork, causing massive accumulations in areas between the hood and fan on the roof.

When using hot water methods, a caustic chemical degreaser should be used to break down grease, so that both hot water and caustic degreaser agents can be flushed into the system to remove grease buildup in inaccessible areas.


After finishing cleaning, kitchen hoods are often polished to improve the appearance and for easier cleaning. Cleaners will put a certification sticker on the hood of every cleaned kitchen exhaust system to show compliance with the local, state, and federal fire codes.

Some white residue may be left after the commercial kitchen grease cleaning. Vinegar and warm water can be used to remove it.

How Does Grease Affect Your Kitchen Systems?

Your kitchen hood exhaust system pulls heat, smoke, and grease-laden vapors out of your restaurant while you’re cooking. This system directs the grease-laden vapors and smoke into your hood, through vent hood filters, and into the ductwork traveling through your kitchen to the exhaust fan on your roof where it can exit the building safely.

These vapors can easily cause fire as they contain flammable residues, such as grease and oils. Without fire suppression systems in the building, these fires can quickly spread and cause catastrophic damage in your restaurant.
