Kitchen Exhaust Cleaning


Kitchen exhaust cleaning involves the thorough scrubbing and degreasing of the kitchen hood, filters, and all the ductwork and fans associated with the exhaust system. These components can accumulate grease and other particulates over time, which can pose a fire hazard and decrease the efficiency of the system. Cleaning typically requires specialized equipment and chemicals to ensure that grease and debris are effectively removed.



  1. Fire Safety: Regular cleaning removes grease that could potentially ignite, thus reducing the risk of kitchen fires.

  2. Improved Air Quality: A clean exhaust system means less grease and fewer particulates are released into the kitchen air, contributing to a healthier work environment.

  3. Energy Efficiency: Clean filters and ducts allow the exhaust system to operate more efficiently, which could lower energy costs.

  4. Compliance: Regular cleaning ensures that the kitchen remains compliant with local health and safety codes.

  5. Enhanced Performance: A clean system performs better in terms of suction and exhaust, which keeps the kitchen cooler and more comfortable.


  1. Cost: Professional cleaning services can be expensive, especially if the kitchen exhaust system is particularly large or complex.

  2. Disruption: The cleaning process can be time-consuming and may require the kitchen to be partially or fully shut down, affecting business operations.

  3. Potential for Damage: If not properly executed, the cleaning process could damage sensitive components of the exhaust system.

  4. Material Limitations: Some exhaust ducts made of flexible materials may be prone to tearing or collapsing during the cleaning, particularly if not handled with care. When possible, these should be replaced with rigid material ducts for longevity and safety.



Kitchen exhaust cleaning is an essential maintenance task that offers several advantages, including improved fire safety, better air quality, and increased system efficiency. However, the process can be costly and time-consuming, and there are potential risks if not executed correctly. It’s important for consumers to weigh these factors and consult with qualified professionals to determine the best course of action for their specific needs.



How a Kitchen Exhaust Hood Should Be Cleaned: A Step-by-Step Guide for Consumers



Understanding the steps involved in cleaning a kitchen exhaust hood can help consumers ensure that they are getting a thorough and effective service. This guide provides a step-by-step breakdown of what a typical professional kitchen exhaust hood cleaning should entail.


Preliminary Steps:

  1. Preparation: The kitchen should be closed to prevent any accidents. The area around the exhaust hood should be cleared of any obstacles, and the electricity and gas should be turned off for safety reasons.

  2. Safety Gear: The cleaning crew should put on appropriate safety gear, such as gloves, eye protection, and coveralls, to protect themselves from chemicals and debris.

  3. Covering Kitchen Appliances: All cooking appliances should be covered with plastic sheeting to protect them from cleaning chemicals and debris.


Cleaning Steps:

Phase 1: The Hood
  1. Initial Inspection: Perform a visual inspection to assess the amount of grease and particulate buildup.

  2. Chemical Application: Apply a degreaser to the interior and exterior surfaces of the hood. Let it sit as per the manufacturer’s instructions.

  3. Scraping and Scrubbing: Use scrapers and brushes to remove the loosened grease and grime. Pay attention to corners and hard-to-reach areas.

  4. Rinsing: Rinse off the degreaser and dislodged grease with hot water.

Phase 2: Filters
  1. Removal: Carefully remove the filters from the hood.

  2. Soaking: Soak the filters in a degreasing solution.

  3. Scrubbing: After soaking, scrub the filters with non-abrasive brushes.

  4. Rinsing and Drying: Rinse the filters with hot water and allow them to dry before reinstalling.

Phase 3: Ductwork and Fans
  1. Access: Open access panels to reach the ductwork and fans.

  2. Chemical Application: Apply degreaser to the interior surfaces of the ducts and fan blades.

  3. Mechanical Cleaning: Use specialized brushes or pressure washers to remove the grease and grime.

  4. Rinsing: Rinse off the degreaser and dislodged material.


Final Steps:

  1. Inspection: Once all components are clean and dry, perform a final inspection to ensure that all grease and grime have been removed.

  2. Reassembly: Carefully reinstall the filters, close the access panels, and reconnect the electricity and gas.

  3. Documentation: A service report should be completed, detailing what was done and any recommendations for future service. This should be provided to the consumer.

  4. Cleanup: Remove all plastic sheeting from appliances and clean up any residual debris or chemicals.


A thorough kitchen exhaust hood cleaning involves multiple steps, from preparation to final inspection. Each component—the hood, filters, ductwork, and fans—needs individual attention to ensure complete removal of grease and particulates. Understanding this process can help consumers ensure that they are receiving a comprehensive service that meets health and safety standards.
