Commercial Restaurant Kitchen Hood Cleaning

Your restaurant exhaust hood gathers the smoke from your kitchen and funnels it in to the plenum area behind your filters. Keeping this area clean is the first step in making sure that your restaurant kitchen exhaust system is fire safe. The prevention of fire is the number one reason to get your commercial hood system cleaned. Removing build-up of grease from your exhaust system is the best way to prevent kitchen fires which cause hundreds of injuries in the United States each year.

Quality Services LLC staff comply with all local fire codes and laws to properly achieve a clean and properly functional hood system. You can expect our technicians to follow the National Fire Protection Association's recommendations for cleaning of commercial hoods by

Where we clean:
  • All components of the system shall be dismantled, and scraped, prior to pressure washing.
  • All interior ductwork, airflow portion of fans, and hood areas to be left completely free of grease.
  • All access panels will be open and clean.
  • Areas by hood will be protected and left clean after the job is completed.
  • Stainless steel hoods are to be polished inside and out.
  • Cleaning crew shall have special cleaning wands and nozzles to reach difficult portions of the ductwork.
  • The chemicals used by the company shall be an alkaline base and biodegradable to prevent damage to metal ductwork and USDA approved for food service use.

It is recommended that industrial establishments doing a moderate amount of cooking have their kitchen hoods cleaned every six months. This recommendation increases to every three months if your establishment is open 24 hours, uses wok cooking, charbroiling or cooks in high volume.

These are the basic procedures we follow when cleaning any kitchen exhaust system:
  • Turn off power to kitchen exhaust fan.
  • Make sure no food is exposed in area near cleaning operations. Drape layers of plastic sheeting over all cooking appliances and nearby prep areas.
  • Locate exhaust fan and prepare for cleaning by safely tipping fan or removing access doors. Run down all grease ductwork, locate and remove all access doors.
  • Degrease and pressure wash all accessible areas, beginning with components of fans, vertical and horizontal ducts, duct collars, or troughs, and finally the hood canopy. Repeat process until all surfaces are cleaned to bare metal.
  • Replace all filters, access doors and fans to original positions. Remove and dispose of all plastic sheeting.
  • Detail polish interior and exterior of hood canopy. Wipe down any excess water from appliances, surrounding walls and prep tables.
  • Restart exhaust fans and check for proper operation.
  • Update and sign hood sticker with date cleaned and next scheduled cleaning.
  • Fill out job service report and get approval signature from client’s representative.
