Where’s the job?

Overview

• Commercial kitchen extraction cleaning involves a thorough removal of grease and debris from hoods, filters, ductwork and fans to ensure safety and compliance.

• Skill level: 4 / 5 (requires detailed cleaning, proper chemical handling and familiarity with ventilation systems).

• Typical duration: 1 – 2 days depending on kitchen size and buildup level.

Safety First

• Disconnect power to the extraction system where applicable to prevent accidental activation.

• Wear appropriate PPE including gloves, eye protection and coveralls when handling degreasers.

• Ensure good ventilation in the work area as cleaning agents and dislodged grease particles can be hazardous.

• Always follow the manufacturer’s instructions for any industrial cleaning chemicals used.

• Use ladders or elevated platforms safely when accessing high ductwork.

Tools & Materials

Step-by-Step

1. Preparation – Ensure the extraction system is switched off and isolate electrical supply; remove filters and accessible components.

2. Disassembly – Carefully detach filters and other removable parts for individual cleaning.

3. Grease removal – Apply industrial degreaser on hood surfaces, filters and duct inlets; let it sit to break down baked-on grease.

4. Manual scrubbing – Use heavy-duty brushes and scrapers to remove residue; pay extra attention to corners and joint areas.

5. Rinsing – Thoroughly rinse all parts and ductwork using a pressure washer or hose to clear away chemical residues.

6. Drying and reassembly – Allow all surfaces to dry completely before reinstalling components.

7. Final check – Switch the system back on, test the airflow and inspect for any residual grease or blockages.

Completion Checks

• All surfaces should be visibly clean and free from grease buildup.

• Filters, ductwork and fans must allow unobstructed airflow.

• The cleaning process should be fully documented to adhere to hygiene and fire safety regulations.

• The system should function at optimal performance with improved extraction efficiency.

When to Call a Pro Instead

For extensive grease buildup, compliance audits or if the extraction system is integrated with fire suppression controls, it is best to engage a professional cleaning service with industry accreditation.
