A service provider working a restaurant kitchen between shifts has maybe forty minutes, a cold kitchen, and a supervisor who wants proof the filters are clean before the breakfast line opens. Filter cleaning fails in that window for one reason: the plan records that someone cleaned, not which filter, at what time, by which method, to what standard. The documentation below is what turns a routine task into evidence a kitchen operator, a fire risk assessor and a franchise auditor can all accept.
1. What the record has to carry
One line per filter per clean. The fields that matter are not debatable: the site and the extract system, the position of the filter in that system, the filter type and mesh style, the date and clock time of both the start and the finish, the crew members on the task, the method and machine used, and the name of the person who signed it off. Where the kitchen trades on two or three shifts a day, a blank column for the shift the clean happened on tells you within a week which window is actually being worked and which is only on paper.
Add an observations column and mean it. "Heavy deposit on the upstream face, second pass required" is a finding; "clean" is not. Over a month, the observations column shows whether the interval between cleans is right for that kitchen's load, or whether the fryer line is loading its filters faster than the schedule assumes.
2. Identification that survives the wash
A filter rack photographed before removal, with the position written on the sheet, costs thirty seconds and removes every argument about whether the filter went back where it came from. Record the frame size, the number of baffles per frame, and any bent or missing baffle you find at removal; a damaged filter cleaned and returned is a defect, not a pass, and it should be written up as one and replaced rather than quietly rehung.
Photographs of the worst face of each filter before and after the clean belong in the same file as the sheet. They are the only part of the record that a client who was not present can read without training.
3. Frequency set by the kitchen, not by a default interval
Weekly is a starting assumption for filters over a busy frying and grilling line, not a rule. A kitchen running a single charbroiler and a hob services its filters less often; a high-volume grill house may need them more often. Test the assumption rather than defending it: the interval is too long when the deposit has gone from soft and wipeable to hard and varnished between two cleans, and it is too short when filters come back from the wash point spotless with a clean crew standing around. The sheet, read across four weeks, makes that judgement visible.
4. Method written down to the mode and the dwell
Cold detergent handles fresh grease. It does little for a polymerised film that has been baked and re-baked, and crews fall back on scrubbing when the method is not specified. For the baked deposit, restaurant kitchen grease cleaning with hot water and high-temperature steam is the practical route, because heat softens the layer before pressure moves it. Name the machine and the mode on the sheet. A fixed steam cleaning machine such as the PowerDe HW02 gives the wash point a 220 V supply, an 80 L tank and a choice between drier and wetter steam; the drier mode puts heat into the deposit, the wetter mode finishes as a rinse once the film has released.
Record three working details against the method: nozzle distance from the face, seconds of dwell on a heavy deposit, and the number of passes. Those three are the difference between a method the night crew repeats correctly and a method that only works when the same person does it. Where the service provider cleans several kitchens with one set of kit, PowerDe cleaning equipment in a mobile configuration moves between sites; where one large site has a wash point of its own, the plumbed fixed unit is usually the better fit. State which one is on the van in the header of the sheet.
5. Acceptance criteria a supervisor can check in seconds
"Clean" cannot be signed off. Write checks that need no discussion: light passes through every aperture of the mesh or between every baffle; no soft or tacky deposit remains on the upstream face; the frame edges and the seal line are free of build-up; the filter is dry enough to be hung without dripping; no detergent smell is left on a filter sitting above open food. Add one line about reinstallation — direction of airflow marked and correct, frame seated with no gap to the duct, retaining clips engaged. A filter put back upside down undoes an excellent clean.
6. Timing, and why the shift gap is the whole job
Between shifts is a fixed budget. The sheet should show how long the task actually takes: filters removed, transported, cleaned, inspected, dried, returned, and the wash point left clean. If the recorded time regularly overruns, the problem is in the method or the crew size, not the crew. A wash point that has to be set up and cleared every visit burns ten of those forty minutes; a fixed unit at the site keeps the task inside the gap. Log the time on the sheet and the constraint becomes obvious within a fortnight.
7. Run-off, drainage and the site's duties
Greasy water leaving a filter wash has to go through the site's grease interceptor, not a prep sink or a floor drain. Record where the wash point discharges, who checks the interceptor, and when it was last emptied. A compliant clean that discharges incorrectly is still a breach, and it is the kind of finding an inspector writes up on the drainage rather than the cleaning.
Note the water volume used per clean as well. It sets the size of the tank the crew needs, it decides whether the site's services can support the work, and it is the number a client asks for when they are comparing two service providers.
8. Health and safety recorded with the task
Steam onto a filter face produces vapour in a small wash area. Record the PPE worn — gloves, apron, eye protection — and confirm the filters have cooled enough to handle after the kitchen's last service. Note who signed the isolation of the extract fan before the filters came out; a filter cleaned while the fan is live is both unsafe and useless, and the sheet should show the fan was proved off at the time of removal.
9. Handover to the kitchen, not just the file
The kitchen's own duty to keep filters clear of heavy deposit between your visits is worth a line on the handover sheet, together with the date of the next planned clean. The client keeps a copy; so do you. If a fire risk assessor or an insurer asks the operator for their record and the operator has none, that gap is charged back to the service provider who left the work undocumented.
10. Machine upkeep on the same sheet
The cleaning fails when the machine does. Record the daily check before the first clean — does it heat, does it hold pressure, are the hose and wand sound — and note any fault rather than working around it. The PowerDe HW02 steam cleaner product page lists leakage, short-circuit, high-temperature, high-voltage and water-shortage protections; the crew needs to know they exist, and also that a machine tripping one of them has to be reported and not reset repeatedly during a shift. Where the water supply is hard, put the descaling interval on the sheet too: scale inside a heater quietly drops output long before the unit actually fails.
11. Review the record every month
Read the sheets monthly by site. Filters that need a second pass every week mean the interval is too long or the method is underpowered. Filters that come back clean with no effort mean the opposite. A task that is consistently unfinished in the last fifteen minutes of the window is a resourcing finding, not a discipline finding. Change the schedule in the document, not in a verbal instruction at the depot.
12. When to have the setup specified for your round
Filter cleaning across a contract kitchen round is a logistics problem before it is a cleaning problem: vans, time windows, wash points and one set of equipment serving several sites. Shenzhen PowerDe Automation Precision Equipment publishes the parameters for each machine in the Cleaning Equipment Series, and customized steam cleaning equipment can be specified against your shift windows, vehicle loading and water supply. Send the number of sites, the filter counts per site and the cleaning window you work to the contact page and ask for a configuration and method matched to that round, rather than picking a catalogue unit and finding the constraint on the first night.
