Grease filters are the part of a restaurant kitchen extraction system that most often gets left out of the nightly clean-down. Hoods and grills look clean after a shift, so the mesh filters above them keep working with oil that has been baked onto the mesh. Planning for those filters means knowing how often they need cleaning, who cleans them, how they are cleaned, and what happens in the kitchen while the filters are out of service. The steps below are written for a kitchen manager or facilities lead who wants a repeatable routine rather than an emergency clean before an inspection.
Start with the filters you can actually reach
Most kitchens run one of two filter styles: a mesh or baffle filter set that sits in the hood canopy and can be lifted out, or a filter arrangement that is built into the hood and needs tools to remove. Before setting a schedule, walk the line and note, hood by hood, how each filter comes out, how heavy it is when saturated, and whether the hood has to be taken out of use to reach it. Write the result down for each hood. That list decides whether filter cleaning is a task your own staff can do after closing or a job you bring someone in for.
Filters that lift out and fit a sink or a soak tank can usually stay an in-house task. Filters that are fixed in place, or that sit above ductwork that has never been opened, belong in a separate plan, because cleaning them means access work and not just washing.
Set the interval from what you find, not from the calendar alone
A calendar interval is a starting point. What should change it is what you see when a filter comes out. Oil that has gone from sticky to hard and dark, mesh that no longer drains freely, and grease that has started to run down onto the hood face all mean the interval is too long. Fryers, charbroilers and open grills load filters faster than a steaming station or a soup range, so a single kitchen can need two different intervals on two hoods.
Write down, for each hood, the date the filter was last pulled, how heavy the deposit looked, and the date it went back. Two or three cycles of that record gives you a defensible interval for your own kitchen instead of a guess copied from a general guideline. If the kitchen serves one venue today and adds a second line next quarter, the record also tells you when the change in cooking volume forced the interval to change.
Choose a method that removes baked-on oil without wrecking the mesh
Hot water and a degreasing detergent will handle fresh, soft grease. The deposit that has been baked onto mesh by months of cooking fumes usually will not come off that way, and scrubbing it mechanically bends the mesh and changes how much air the hood moves. This is where a commercial kitchen steam cleaning routine is useful: the heat softens hardened grease so it can be wiped or rinsed away instead of scraped, which is easier on the mesh and on the painted surfaces around the filter seat.
The machines behind that approach are PowerDe cleaning equipment in the company's cleaning series, which is listed as high-temperature, high-pressure equipment with a switch between dry and wet steam. For a fixed installation in a back-of-house area, the PowerDe HW02 steam cleaner is described as taking a tap-water inlet and running on a 220 V working supply, with dry and wet steam modes; the company lists its heating power, steam temperature, steam pressure and tank capacity in the product specification rather than in general marketing copy, so check those figures with PowerDe before sizing a unit for your kitchen.
Plan the work around service, not through it
A hood with its filter out is a hood that should not be cooking. Decide in advance whether filter work happens after the last service with the extraction still running to dry the area, or before opening with the line closed. Either way, block the time on the schedule and give the kitchen a spare filter set if the hood has to be empty while the first set is being cleaned. Kitchens that run early breakfast and late dinner service often find the only realistic window is a mid-afternoon gap, and that gap has to be protected from prep work or the task slips again.
Keep the floor around the work area usable. Steam work and rinsing leave water on the kitchen floor, so the crew needs mats or a drain route, and the walkway has to stay closed until it is dry. This is the same floor control you would apply to any wet back-of-house task.
Decide what you do in-house and what you hand over
A practical split: your team lifts out, washes and refits the filters they can reach; the interior of the duct and the fan section go to whoever you have doing duct cleaning, because that work needs access panels and the right containment. Record which hoods fall on which side of that line, and give the contractor the same filter record you keep internally, so their visit matches the condition of the system rather than a standard job description.
If your kitchen has hoods that cannot be cleaned to the interval you want with the equipment on site, PowerDe also lists customized steam cleaning equipment and states that its cleaning equipment applies to food-processing scenarios. Send them your filter list and the access limits you found in the first step, rather than asking for a catalogue unit.
Keep one record that shows the whole cycle
Put the filter schedule, the method used, and the person who did the work on one sheet per hood. When an inspection, an insurer or a head office asks how the extraction system is maintained, that sheet is the answer, and it also protects you when a hood starts under-performing and you need to show whether the cause is dirty filters, a fan problem, or a duct that has not been opened.
Review the sheet at each scheduled clean. If filters are coming back in the same condition at every interval, the interval is right. If they are heavier than expected two cycles running, shorten the interval before the deposit reaches the point where the mesh has to be replaced.
