Professional Restaurant Hood Vent Cleaning in Detroit. Full Process Explained

A complete walkthrough of the professional hood cleaning process for restaurants and commercial kitchens across Metro Detroit; including ducts, fans, and rooftop systems.

🧼 What Happens During a Professional Hood Cleaning? Inside the Process (Detroit & Surrounding Areas)

If you run a restaurant or commercial kitchen in Detroit, Ann Arbor, Troy, Novi, Dearborn, Warren, Livonia, or Royal Oak, you already know a clean exhaust system isn’t just about appearances, it’s fire safety, airflow, and compliance.
Here’s a transparent, step by step look at what our professional hood cleaning process includes so you know exactly what you’re getting.


🔥 Why Regular Hood Cleaning Matters

  • Fire Prevention: Grease in hoods, ducts, and fans is fuel. Proper cleaning removes ignition risks.
  • Airflow & Comfort: Clear ducts mean better ventilation and cooler kitchens.
  • Compliance & Insurance: Stay compliant with NFPA 96 and keep your coverage valid.
  • Equipment Life: Fans and make up air units last longer when kept grease free.

🧰 Step by Step: Our Commercial Kitchen Hood Cleaning Process

1. Arrival, Walkthrough & Safety Setup

  • Confirm service scope, rooftop access, and utilities.
  • Protect cooking equipment with plastic sheeting and magnetic filter covers.
  • Secure fans, set up wet floor signage, and prep drainage.

2. System Disassembly & Pre Clean

  • Remove baffle filters, access panels, and light covers.
  • Scrape heavy grease from the hood plenum, ducts, and fan blades.
  • Install or inspect rooftop grease containment systems.

3. Degreaser Application (Top Down Method)

  • Begin from the roof fan, working downward for proper flow.
  • Apply a food safe alkaline degreaser to break down buildup.
  • Allow dwell time for deep penetration before rinsing.

4. Heated Pressure Rinse

  • Use hot water pressure washing to flush grease through the ducting.
  • Capture rinse water per EPA guidelines.
  • Repeat until bare metal is visible as required.

5. Filter & Exterior Detailing

  • Soak, rinse, and reinstall baffle filters.
  • Polish hood exteriors and splash zones for a professional finish.

6. Fan & Belt Check

  • Inspect belts, bearings, and pulleys; replace if needed.
  • Verify exhaust fan spin and airflow.

7. Final Rinse & Reassembly

  • Remove coverings, wipe surfaces, and dry floors.
  • Reinstall panels and filters; restore full system power.

8. Photos, Report & Compliance Sticker

  • Deliver a service report noting issues or recommendations.
  • Apply a dated compliance sticker for inspectors.
