Grease Buildup Removal

Grease Buildup Removal

Fire Hazard Reduction • Improved Ventilation • Cleaner, Safer Kitchens

Grease buildup is one of the most common—and most dangerous—issues found in both commercial and residential hood and ventilation systems. Each time you cook, tiny grease particles rise into the air and are pulled into the hood canopy. From there, they move into the filters, vents, ducts, plenum areas, and exhaust fan. Even with daily surface cleaning, a significant amount of grease escapes into the system. Over time, these particles harden into thick, sticky, flammable layers that standard cleaning techniques cannot remove.

This accumulated grease poses serious safety risks. Just one small flare-up at the cookline can ignite these deposits, allowing fire to travel rapidly through the ventilation system. Grease-fed fires are among the most destructive types of kitchen fires and are a major cause of property damage in commercial food establishments. Even in residential kitchens, grease buildup can lead to strong odors, restricted airflow, fan strain, and increased smoke inside the home.

At Aurora Kitchen Hood Cleaning, our Grease Buildup Removal service is designed to eliminate these hazardous and hard-to-reach layers of grease from every accessible part of your hood and exhaust system. Using high-strength, kitchen-safe degreasers and specialized mechanical tools, we break down and remove grease that has built up over months or even years—restoring your ventilation system to a safer, more efficient condition.

⭐ Why Grease Buildup Occurs

Grease buildup is a natural result of everyday cooking, especially in kitchens that prepare fried foods, grilled meats, sautéed dishes, or anything that produces smoke and vaporized oils. Even light cooking over long periods contributes to buildup.

Grease accumulation is often found in:

• The hood canopy

• Filters and filter housings

• Plenum areas

• Vent openings

• Interior hood walls and corners

• Vertical and horizontal ducts

• Exhaust fan housing and blades

What begins as a thin, oily film gradually becomes a hardened, layered mass that acts as fuel in the event of a fire.

Most kitchens clean the exterior of the hood regularly, but internal areas are difficult to access without professional tools and techniques. Over time, serious buildup can go unnoticed until it becomes a critical hazard.

⭐ The Dangers of Grease Buildup

✔ Fire Hazard

Grease buildup is extremely flammable. If flames reach the internal system—whether from a flare-up, electrical malfunction, or fan overheating—the grease can ignite instantly.

✔ Restricted Airflow

As grease thickens inside the system, it narrows openings and restricts ventilation. This leads to increased smoke, odors, and heat in the kitchen.

✔ Increased Odors

Old grease emits unpleasant, lingering odors that spread throughout the kitchen and dining areas.

✔ Fan Strain and Overheating

A clogged system forces the exhaust fan to work harder, reducing efficiency and increasing the risk of mechanical failure.

✔ Non-Compliance with NFPA 96

Commercial kitchens are required to maintain clean ventilation systems. Excessive grease buildup can lead to failed inspections, fines, or forced closures.

✔ Shortened Equipment Lifespan

Grease corrodes metal components and accelerates wear on motors, ductwork, and filters.

Removing grease buildup is essential not only for fire safety, but also for overall kitchen performance and hygiene.

⭐ Our Grease Buildup Removal Process

We follow a detailed, multi-step cleaning approach designed to reach grease deposits that everyday cleaning cannot touch.

✔ 1. System Evaluation

We inspect the hood, filters, plenum, ducts, and fan to determine the level of grease accumulation and identify high-risk areas.

✔ 2. Surface Grease Removal

We remove loose, visible grease from hood surfaces to access deeper buildup.

✔ 3. Deep Degreasing of Interior Hood Surfaces

Using powerful but kitchen-safe degreasers, we break down layers of hardened grease from:

• Hood walls

• Corners

• Filter housings

• Plenum areas

✔ 4. Mechanical Grease Removal

In areas with severe buildup, we use specialized scraping tools to remove thick, baked-on grease deposits that cannot be dissolved with chemicals alone.

✔ 5. Vent and Duct Degreasing

Grease around vent openings and within the duct entrances is removed to restore airflow and reduce fire risk.

✔ 6. Exhaust Fan Degreasing

We clean accessible parts of the exhaust fan where grease commonly accumulates, such as:

• Blades

• Housing

• Motor casing

✔ 7. Final Rinse & Surface Restoration

After degreasing, we rinse and wipe all accessible areas to restore clean, safe surfaces.

✔ 8. System Performance Check

We verify improved airflow, reduced odors, and proper mechanical function after cleaning.

⭐ Benefits of Professional Grease Buildup Removal

✔ Reduced Fire Risk

Removing flammable grease layers significantly lowers the chance of ignition.

✔ Improved Ventilation

Cleaner vents and ducts increase airflow and improve odor and smoke control.

✔ Cleaner Kitchen Environment

Less grease in the ventilation system means cleaner air and fewer odors.

✔ Improved Equipment Efficiency

Fans and motors perform better when not burdened by airflow restrictions.

✔ Longer System Lifespan

Removing corrosive grease helps preserve metal components and reduce repairs.

✔ Health & Safety Compliance

Stay inspection-ready and avoid violations or forced shutdowns.
