Grease Extraction Cleaning



we now use the Lifa combi 15 duct cleaning method on our grease ducting to ensure we reach all areas

Here at grease extraction cleaning bradford we offer a fully bespoke, personal and yet professional approach to your kitchen cleaning needs. Every kitchen is different. A different size. A different location. A different set of staff, offering a diferent choice of menus.


Why then would you want to manage your kitchen in the same way that everyone else does? Its not the same as everyone else's.

And that is what grease extraction cleaning Leeds understands, and will put first and foremost.

A fire, or major accident in the kitchen, in the UK, occurs more than three times a day! This is due to the surface canopies, the connecting filters and their adjoining ducting systems, building up with grease and other unpleasant and unwanted deposits. These unescessary build ups can cause humidity, condensation, unwanted increased kitchen temperatures, all of which can lead to food contamination! The resulting conditions provide an ideal breeding ground for cockroaches, and other unpleasant, unwanted vermin, due to the increased heat and the absence of light.

Yet, this isn't even the worst thing that a malfunctioning ventiliation system can cause. A fire, caused by a faulty unit, is more likely, due to the heat, location, grease and other at-hand cooking materials.





The upkeep is not a procedure that is advised to be left to your own staff and so here at grease extraction cleaning sheffield we are fully safety-certified to consult and to supervise your ventiliating needs. Occasionally, panels need to be installed in order to clean certain inaccessable kitchen areas. The filters themselves should be chemically soaked (in order to remove any microscopic surface residue – something that not all cleaning companies will undertake to do), then degreased, using a high-pressure steam cleaning system.

At grease extraction cleaning Manchester we also advise that the canopies themselves then require further separate cleaning – whatever their material and composition, whether fibre glass, galvanised or stainless steel. All materials require a slightly different approach, to be cleaned both internally and externally. For example, each unit consists of myriad light-fittings, pipework, drip trays, grills, covers and housing. Then imagine the small areas that these mightr be housed, or connected within All these areas listed require specific attention, which grease extraction cleaning Bradford can advise you on further.

In addition to cleaning the units, grease extraction cleaning Leeds would advise that, in conjunction with your various warranty obligations, a planned maintenence is arranged, in order to investigate and to flush out the problem, long before it impacts your business detrimentally. In business, as in life, prevention is better than cure! This then significantly reduces the risk of fire, and continually leads to a healthier and better working environment for your staff.  

Here at grease extraction cleaning Sheffield we are fully qualifed, equipped and certified to consult and to carry out all the above, and all proofs can be provided upon request. Please contact grease extraction cleaning Manchester directly on emails, address, or telephone in order to discuss your individual cleaning requirements, or for a no-obligation quote. 

TR/19 HVCA Section 7 - Guide to Good Practice - Internal Cleanliness of Ventilation Systems
Detailed below are just some extracts from: TR/19 HVCA Guide to Good Practice - Internal Cleanliness of Ventilation System

Table 8: Location of Access Panels for Cleaning and Inspection Purposes
Volume Control Dampers Both sides
Fire Dampers (see Note 7) Both sides
Attenuators Both sides
Changes in Direction Both sides
Filter Sections Both sides
Horizontal Ducts Generally every 3 metres (see Note 2)
Risers Top and bottom as a minimum (see Note 3)
Extract Fans Both sides (see Note 4)
Discharge grille/mesh One side (see Note 6)

• 7.23 Measurements should be taken at the following locations where practicable:
• Canopy/Extract plenum behind filters
• Duct 1 metre from canopy
• Duct 3 metres from canopy
• Duct midway between canopy and fan
• Duct upstream of fan
• Discharge duct downstream of fan

• 7.24 Table 9 sets out guideline maximum levels of grease deposit and actions recommended. The actual recommended action timing will depend on the rate of accumulation, the risk vulnerability of the system and site and any particular warranties imposed by the building insurers.
Table 9: Surface Grease Deposit Limits
Wet Film Thickness Test Measurement Recommended Action
200μm as a mean across the system Complete cleaning required
Any single measurement above 500μm Urgent local cleaning required

Cleaning Methods
• 7.28 This guide is not intended to be definitive in relation to the method of cleaning, as there are many existing methods that can be applied in tandem, and emergent new technologies. Examples of cleaning methods are listed in Table 10.
• 7.29 To conform with the Guide, the actual method or methods must be capable of achieving the required results, i.e. Post-Clean Verification, not only on the internal surfaces of the extract duct but also on system components.
• 7.30 When choosing the cleaning method, consideration should be given to operative safety and also to effects on the surrounding environment, particularly where using wet cleaning methods, since grease/moisture can leak from the ductwork components and damage the surrounding fabric.
Table 10: Examples of Cleaning Methodology
Generic Name Energy Source Removal Method
Hand wipe Manual Wiping the surface of the ductwork
Hand scrape Manual Removing heavy deposits by hand scraping
Chemical Manual Softens or dissolves deposits making themsuitable for hand scraping
High pressure water wash (steam) Electrical or compressed air Vapour or liquid expelled at high pressurefrom lance to dislodge/dissolve deposits
Blasting (remote or direct) using suitable medium as appropriate Compressed air Blasting medium dislodges contaminant from duct and component surfaces to be removed via vacuum techniques or high volume filtered extraction.

Table 11: Frequency of Cleaning
Heavy Use 12-16 hours per day - 3 monthly
Moderate Use 6-12 hours per day - 6 monthly
Light Use 2-6 hours per day - 12 monthly
Post-Clean Verification of Cleanliness
• 7.42 The level of cleanliness is that no single measurement should exceed 50μm
• 7.43 On completion a report should be provided containing the following:-
• The system(s) cleaned
• Pre-clean measurements (as per System Testing)
• Post-clean measurements
• Photographic records
• Additional works carried out (if any)
• COSHH data on any chemicals used
• Recommendations for future cleaning requirements
• Observations on the condition of the ductwork system
• A sketch or schematic of the system indicating access panel and testing locations and highlighting any uncleaned areas with a written explanation as to why the area could not be accessed/cleaned (see paragraph 7.6)
• 7.44 If specified, additional kitchen extract safety issues should also be reported (as outlined in paragraph 7.26).
• 7.45 The Post-Clean Verification of Cleanliness report should assist to serve as evidence of system status to insurance assessors, Environmental Health Officers, landlord’s agents, etc.

Extract Cleaning

A fire occurs every 6 hours because canopies, filters and ducting systems become built up with deposits of grease, particularly in areas adjacent to deep fat fryers. Beside a fire risk these deposits can lead to humidity, high temperatures...
