When Cater Clean 24 Seven attended a hotel restaurant for a professional kitchen extract cleaning service, our technicians encountered a heavily contaminated extraction system that presented a significant fire risk.
The internal ductwork had accumulated extensive grease deposits, coating the surfaces and creating a potentially hazardous environment.
In a busy hotel restaurant, extraction systems regularly remove smoke, heat and grease-laden vapours from cooking areas. Over time, grease can accumulate inside the ductwork, particularly in areas that kitchen staff cannot access during routine cleaning.
Without regular kitchen extract cleaning, these deposits can become a serious fire hazard, potentially allowing flames to spread through the extraction system.
The condition of the ductwork at this hotel highlighted why professional cleaning and proactive maintenance are essential for commercial kitchens.
Our solution: Professional kitchen extract cleaning
Our specialist technicians carried out a thorough cleaning of the affected ductwork, focusing on removing the extensive grease deposits from the internal surfaces.
The cleaning process addressed the contamination identified during the initial inspection, transforming the condition of the ductwork.
Our main objectives were to:
- Remove the heavy grease deposits from the affected ductwork.
- Eliminate the accumulated combustible grease from the cleaned surfaces.
- Significantly reduce the associated fire risk.
- Improve the cleanliness and hygiene of the extraction system.
- Document the transformation through before-and-after photographs.
Professional kitchen duct cleaning is particularly important in hotels and restaurants, where ductwork can extend through ceilings, service voids and other concealed areas.
Cleaning must address the internal ductwork rather than simply the visible canopy and filters.
The results: From high-risk contamination to clean ductwork
The before-and-after photographs from this project demonstrate the substantial difference that professional kitchen extract cleaning can achieve.
Before cleaning: A serious grease-related fire hazard
Before our technicians began work, the ductwork contained extensive grease deposits across its internal surfaces.
This contamination presented a high fire risk and required specialist attention to remove the accumulated combustible material.
After cleaning: Grease deposits removed
Following the kitchen extract cleaning, the affected ductwork showed a dramatic improvement.
The previously contaminated surfaces were visibly clean, with the accumulated grease removed from the treated sections.
Most importantly, removing the grease significantly reduced the associated fire risk within the cleaned ductwork.
The result demonstrates the value of addressing grease accumulation before it develops into an even greater safety concern.
Why regular kitchen extract cleaning is essential for hotels and restaurants
Commercial kitchens generate significant volumes of airborne grease, particularly during periods of intensive cooking.
Although canopy filters capture some grease particles, deposits can still accumulate further inside the extraction system.
Regular kitchen ventilation cleaning and ductwork maintenance help hotels and restaurants:
- Reduce fire risks: Removing combustible grease helps prevent the accumulation of hazardous deposits.
- Support compliance: Regular cleaning and documented maintenance help businesses demonstrate responsible fire safety management.
- Maintain kitchen hygiene: Removing grease and contamination contributes to cleaner extraction systems.
- Protect business operations: Proactive maintenance reduces the likelihood of unexpected problems and potentially costly disruption.
- Support insurance requirements: Cleaning records and photographic evidence can help demonstrate that appropriate maintenance has taken place.
For hotel groups, restaurant operators and facilities managers, professional duct cleaning services should form part of a planned maintenance programme rather than being arranged only when contamination becomes severe.
The importance of before-and-after photographic evidence
One of the challenges with kitchen extraction systems is that much of the ductwork remains hidden from view.
This makes photographic reporting particularly valuable.
In this case, the difference between the heavily contaminated ductwork and the cleaned surfaces was immediately visible.
Before-and-after photographs provide hotel management and facilities teams with a clearer understanding of the condition of the accessible ductwork and the improvements achieved.
Cater Clean 24 Seven supports clients with professional reporting, helping them maintain accurate records of their kitchen extract cleaning in London and across the UK.
Does your hotel or restaurant require kitchen extract cleaning?
This project highlights the importance of identifying and addressing grease contamination before it creates unnecessary risks for a commercial kitchen.
