Clearing the Air :
The Ultimate Guide to Extraction Cleaning.

Commercial extraction systems play a vital role in maintaining air quality and safety in commercial kitchens. However, regular cleaning of these systems is often overlooked, leading to a build-up of grease, dirt, and other contaminants that can pose serious health and fire hazards. In this comprehensive guide, we’ll explore the importance of commercial extraction cleaning and recommend cleaning intervals based on usage levels, ensuring optimal performance and safety in every kitchen. 

The Importance of Commercial Extraction Cleaning 

Fire Safety: 

Grease buildup in extraction systems is a significant fire hazard in commercial kitchens. The accumulation of grease on filters, ducts, and fans increases the risk of a grease fire, which can spread rapidly and cause extensive damage to property and endanger lives. Regular cleaning of extraction systems removes grease deposits and reduces the risk of fire, ensuring a safe working environment for kitchen staff and patrons. 


Air Quality: 

Extraction systems are designed to remove smoke, steam, and airborne contaminants from the kitchen environment. However, over time, grease and dirt buildup can obstruct airflow and compromise the system’s efficiency, leading to poor air quality and unpleasant odors in the kitchen. Regular cleaning of extraction systems improves airflow, removes airborne particles, and maintains optimal air quality, creating a healthier and more comfortable working environment for kitchen staff. 



Health and safety regulations mandate regular cleaning and maintenance of commercial extraction systems to ensure compliance with industry standards. Failure to adhere to these regulations can result in fines, penalties, and even closure orders. By scheduling regular cleaning intervals for extraction systems, businesses can demonstrate compliance with regulatory requirements and avoid potential legal consequences. 

Recommended Cleaning Intervals 


To maintain the efficiency and safety of commercial extraction systems, it’s essential to adhere to recommended cleaning intervals based on usage levels. Here are the recommended cleaning intervals for different levels of usage: 


Heavy Use (12-16 hours/day): 

For kitchens that operate for extended periods every day, with heavy cooking activities, it’s recommended to clean the extraction system every 3 months. This frequent cleaning interval ensures that grease and other contaminants are promptly removed, minimising the risk of fire and maintaining optimal airflow and air quality. 


Moderate Use (6-12 hours/day): 

Kitchens with moderate usage levels, operating for several hours each day, should schedule extraction cleaning every 6 months. This interval strikes a balance between maintaining cleanliness and avoiding excessive downtime for cleaning, ensuring that the system remains efficient and compliant with safety regulations. 


Light Use (2-6 hours/day): 

For kitchens with light usage, operating for a few hours each day, annual extraction cleaning is sufficient. While the risk of grease buildup and fire hazards is lower in these environments, regular cleaning is still essential to prevent the accumulation of dirt and maintain optimal system performance. 

Regular cleaning of commercial extraction systems is essential for ensuring fire safety, maintaining air quality, and complying with regulatory requirements. By adhering to recommended cleaning intervals based on usage levels, businesses can minimise the risk of fire hazards, improve air quality, and demonstrate their commitment to safety and compliance.
