Behind the Shine: What a Real Hood Cleaning Looks Like
If you’ve ever peeked into your kitchen’s exhaust hood and wondered, “What exactly do they do when they clean this thing?” — you’re not alone. Many restaurant owners picture someone simply wiping down a shiny metal surface.
In reality, a professional hood cleaning is a deep, detailed, and highly regulated process that goes far beyond appearances. At All City Hood Cleaning, we remove grease, grime, and buildup from every inch of your exhaust system — from the filters above your fryers to the fan blades on your roof.
It’s not glamorous work, but it’s vital to keeping your kitchen running safely and efficiently.
Why Hood Cleaning Is So Important
Every time you fire up a grill, fryer, or broiler, smoke and grease-laden vapors rise into your hood system. While your filters catch some of it, much of that residue continues up into the ducts and exhaust fan. Over time, it becomes a sticky, flammable film.
That’s why fire safety codes — including the NFPA 96 standard followed by local inspectors — require full-system cleanings. A certified hood cleaning removes grease before it can ignite, improves airflow, and keeps your restaurant compliant with insurance and health regulations.
But how does it all work? Let’s lift the hood (pun intended) and walk through the process.
Step 1: Preparing Your Kitchen
Professional hood cleaning starts long before the scrubbing begins. Our crew begins by covering all cooking equipment, prep tables, and flooring with heavy-duty plastic sheeting. This ensures grease and cleaning solution stay where they belong — not on your kitchen line.
We also turn off gas valves, unplug appliances if needed, and create safe work zones so your equipment is protected and your kitchen remains spotless.
Step 2: Disassembling the Exhaust System
Next, we carefully remove filters, access panels, and fan components to expose the interior of the exhaust system. Many restaurants are surprised by what hides behind those panels — layers of dark grease that accumulate even in kitchens with daily maintenance.
We take this step seriously because a hood cleaning that skips your ducts or fan housing isn’t truly clean — and won’t pass inspection.
Step 3: Degreasing and Pressure Washing
Here’s where the heavy lifting happens. Using professional-grade degreasers and hot-water pressure washing, we clean your:
-
Hood canopies
-
Baffle filters
-
Interior ductwork
-
Fan blades and housings
-
Rooftop exhaust components
We apply degreaser to break down hardened residue, then use 180-degree-plus water pressure to flush everything clean. This not only removes grease but also helps spot any mechanical issues like worn belts or loose fasteners.
For rooftop fans, we always protect your roof from overspray and runoff, leaving the area as clean as when we arrived.
Step 4: Rinse, Reassemble, and Polish
Once all components are clean, we rinse away residue and reassemble your system piece by piece. We check that fans spin freely, filters fit properly, and airflow is restored.
Then comes the satisfying part — polishing. Stainless steel hood surfaces are cleaned and buffed to a mirror finish. The result isn’t just safe; it’s something your staff can take pride in seeing every day.
Step 5: Documentation and Compliance Tag
Every service ends with documentation. We take before-and-after photos for your records, note any areas of concern, and provide an official All City Hood Cleaning Service Tag with the cleaning date and recommended next service.
This tag proves compliance with NFPA 96 standards and local fire inspections. It’s one small sticker that carries a lot of peace of mind.
How Long Does It Take?
Depending on your kitchen’s size and configuration, a full cleaning can take anywhere from 2 to 6 hours. We offer flexible scheduling, including early-morning or overnight appointments, to avoid disrupting your regular service hours.
What You’ll Notice Afterward
A professionally cleaned hood system does more than meet code. You’ll notice:
-
Stronger, quieter ventilation
-
Less lingering smoke or odor
-
Cooler air on the cooking line
-
Lower fire risk and better airflow
-
A more confident feeling before inspections
It’s one of those behind-the-scenes services that affects everything about your daily kitchen operations.
