Deciding upon when kitchen extract canopy and grease filter maintenance should take place and how often, is mostly subjective. Ultimately, the responsibility for these decisions rest with the manager of the facility. To help make the best decisions about when to clean, here is some guidance:
The following tables give an indication as to how often certain types of installation should be cleaned.
Grease filters and grease collection drawers should be designed, sized and constructed to be robust enough to withstand regular washing in a commercial dishwasher as this is the most thorough and labour-efficient method of cleaning them yourselves. When re-installing filters, always make sure that they are the right way around i.e. with any framework drain holes at the front, lowest edge.
When handling any components of a canopy, it is imperative that operatives wear proper, gripping, cut-resistant work-gloves for protection against metal edges, as well as the detergents and cleaning agents used. No matter how well finished a filter panel may be, it is easy to cut soft water-soaked skin during the cleaning process. Grease filters by their very nature will have a coating of grease and therefore will be slippery and difficult to handle. Suitable gloves can be obtained easily through most suppliers of personal protective equipment. Access to filters for removal & replacement will often mean reaching above head height and as such, suitable access equipment and or safe working procedures may be required.
It is strongly recommended that an in-house, site specific risk assessment of these hazards should be carried out. Canopies and their components must be designed to be easy to clean. Providing that cleaning intervals are not left too long, washing with soap or mild detergent and warm water, followed by a clear water rinse is usually quite adequate for our equipment. When too long a period is left between cleans, grease will become baked-on and require special attention. An enhanced aesthetic appearance will be achieved if the cleaned surface is finally wiped dry.
No grease filtration is 100% efficient and therefore there will always be a certain amount of grease carried through the filters and deposited on the internal surfaces of the filter housings, plenums and ductwork. Once again, the amount of grease carried through any filtration system will depend very much on the type of cooking and ingredients used. If left unattended, this layer of grease on the non-visible surfaces of the canopy creates both hygiene and fire risks. For these reasons it is necessary to have a deep clean operation carried on a maximum of a six-monthly cycle and even as often as three-monthly in extreme situations.
We always recommend that if there are no specially trained staff, who are experienced at maintenance of these sorts of system available on site, that a specialist sub-contractor (such as Pro-Duct Clean Ltd) be engaged and retained for the purpose. In the case of specialist odour removal systems such as UV, ESP or Carbon Cells, a specialist should definitely be sought and if in-house staff members are to be used, they will require special training in monitoring, testing and handling of the various components.

‘First of all I would like to say how professional your team were when they cleaned our extraction last Friday, as I had mentioned, it had not been done before properly and they were there until 3am and it all seems to be working a lot better. They were lovely lads, a real credit to your Company.’Holiday park Manager2015
