A professional hood cleaning keeps your kitchen safer and your exhaust system working the way it should. It also goes more smoothly when the kitchen is ready for the crew. If you want to prepare for hood cleaning at your restaurant, a little planning ahead protects your food, your equipment and your schedule. This checklist covers what to do before the crew arrives, what usually happens during the service and what to do afterward.
Why Preparation Matters
Hood and duct cleaning is thorough work. Technicians remove grease from the hood, filters, ductwork and exhaust fan, and they use water, degreaser and tools that can spray or drip. Clearing the area in advance helps the team work faster, protects your kitchen and shortens the time your restaurant is affected. Good preparation also helps you avoid delays that can push the service into your busy hours.
Step 1: Choose the Right Time
Most hood cleaning is scheduled after closing, overnight or on a slow day. Pick a window when the kitchen can be fully shut down and cool. Confirm the date with your provider in writing, and let your managers and opening staff know so no one fires up the line early. If you are not sure how often your system needs service, our guide on how often a restaurant should schedule hood cleaning in South Florida can help you plan a schedule that fits your cooking volume.
Step 2: Shut Down and Cool Cooking Equipment
Turn off all cooking equipment under the hood well before the crew arrives. Fryers, grills, ranges and ovens should be off and cool to the touch. Technicians cannot safely work above hot surfaces, and shutting down early prevents last-minute delays. If you use a pilot light or gas appliances, ask your provider whether they have any special requirements.
Step 3: Clear the Cooking Line
Remove items from the cooking line and the area around it:
- Pots, pans, utensils and cooking tools
- Food, oil and ingredients stored near the hood
- Small appliances, racks and anything on shelves under or beside the hood
- Mats, trash cans and anything else on the floor near the equipment
Whatever cannot be moved should be covered. Ask your provider whether they bring their own protective covers or expect you to supply some.
Step 4: Protect Food and Prep Areas
Move open food, prep boards and clean dishware out of the work area. Even careful crews use water and degreaser, so it is wise to store food in a cooler or another room until the job is done. Make sure anything that goes into customer-facing areas is clean and covered.
Step 5: Give Access to the Roof and Equipment
A complete cleaning includes the exhaust fan and the parts of the duct system you cannot see from the kitchen. That often means the crew needs access to the roof or the area where the fan is located, plus any access panels in the ductwork. Before the date, make sure roof keys, ladders or doors are available, and that nothing is blocking access panels. Let the provider know about any restrictions in advance.
Step 6: Review Your Fire Protection and Documentation
Tell the crew about your fire suppression system and any known issues, such as a loose panel, a leaking hood or a noisy fan. Keep your previous service reports where the crew can find them. After the job, you should receive documentation of the work. This record matters for inspections, which is covered in our post on the hood cleaning certificate and what inspectors look for.
Standards such as NFPA 96 set expectations for ventilation control and fire protection of commercial cooking operations, and your local fire authority decides how they are enforced in your area. Ask your provider how their service supports your compliance.
What Happens on Service Day
The crew will typically cover surrounding equipment, remove and clean the filters, degrease the hood and accessible duct sections, and clean the fan. They may photograph the system before and after the work. Expect noise and water, and expect a damp floor that needs to be dry before staff return. Confirm with the lead technician when the kitchen can be used again.
After the Cleaning
- Walk the kitchen with the technician and ask questions about anything they found.
- Reinstall filters only as directed, and make sure they are the right type and seated correctly.
- Keep the service report and any photos on file.
- Note the date of the next service and add it to your calendar.
- Watch for early signs between cleanings. Our article on warning signs your commercial kitchen exhaust needs cleaning lists what to look for.
