Grease filters are the part of a restaurant exhaust system that most often gets overlooked. The hood looks clean, the fans still spin, and the filters still let air through, so the task slips to the end of the week. Then a fire-marshall visit, a strong odour during service, or a sudden drop in extraction performance brings it back to the top of the list. A written checklist is the simplest way to stop that from happening, because it turns a vague intention into dated, assigned work that anyone on the team can pick up.
Start with what actually has to be cleaned
Before assigning frequency, list every grease filter in the building and record how it is mounted. In most commercial kitchens this covers the baffle filters inside the hood, the grease cups or troughs at the edge of the hood, the fan housing behind the filters, and the areas around the hood face and backsplash. Kitchens with a restaurant kitchen grease cleaning routine usually also include the range hood exterior, the stovetop guards, and the wall panels directly behind the line, since splatter there feeds back into the filters.
Write the list once, verify it against the hood drawings or the installer's handover sheet, and number each filter. Numbering matters: it lets a checklist say "filters 3 and 4" instead of "some of them", which is how tasks get missed on a busy night.
Set a frequency for each item, not one blanket rule
Frequency should follow cooking volume and the type of cooking, not the calendar month. A plan that works in practice separates the work into three rhythms:
- Daily: wipe the hood face, backsplash and filter edges; empty grease cups; note any filter that looks heavily loaded.
- Weekly: remove the baffle filters and degrease them, either in a sink with hot detergent or with a commercial kitchen steam cleaning pass on the hood and stovetop area.
- Monthly or quarterly: inspect the fan housing and the accessible part of the duct, and book a deeper clean where the build-up has moved past the filters.
Charbroiling and heavy frying load filters faster than steaming or baking, so a kitchen doing a lot of grilling should expect to soak and clean filters weekly rather than fortnightly. Record the interval you chose and the reason for it, so a new supervisor can see the logic instead of quietly shortening it.
Describe the method, not just the task
"Clean the filters" is not an instruction; a line cook needs to know what clean means and how to get there. Write the steps out: how to release the filters, whether they soak, what tool scrubs the mesh, how the housing is wiped while the filters are out, and how the filters are dried and re-seated so the baffles still face the correct direction. Include what to do if a filter is warped or the mesh is damaged, and where to note that it needs replacing.
For the surrounding surfaces, teams increasingly specify the cleaning medium as well as the task. High-temperature steam loosens cooked-on grease without soaking the floor or the electrical parts of the hood, which is why central kitchen degreasing work on hoods, stovetops and floors is often done with a fixed or hand-pushed machine instead of buckets and hoses. PowerDe's cleaning equipment series covers both formats, including the fixed HW02 unit and the hand-pushed HMW3 unit, which switch between dry and wet steam.
Put names and dates on the sheet
A checklist with no owner is a wish list. For each line include: item number, task, frequency, the person responsible, the date completed, and a signature or initials column. Keep the sheet where the work happens — inside the hood door or on the kitchen office wall — rather than in a manager's folder. When a task is late, the sheet shows it in seconds, and the shift leader can reassign it during prep instead of discovering it at close.
Add a short exceptions box for anything abnormal: a filter that will not come loose, oil pooling under the hood, unusual fan noise, or build-up visible when you look up into the duct. Those go to maintenance the same day, not to the next scheduled clean.
Keep the records that inspections ask for
Fire and hygiene inspections generally want evidence that the cleaning happens on a set interval, plus invoices or work orders for the deeper duct cleaning. Staple a copy of the completed checklist to those documents and keep them for the period your local authority expects. This is also the file you show an insurer, and the one that proves your team was managing grease build-up deliberately rather than by chance.
Review the checklist with the people using it
Bring the kitchen team in every quarter and ask what is not working: which line always gets missed, which task takes longer than written, which supplies run out. A checklist written by someone who never works the line tends to be unrealistic, and unrealistic checklists get abandoned after two weeks. Adjusting two lines a quarter is what keeps the sheet alive.
If your kitchen is cleaning filters on the same interval it set years ago, or if the same task keeps getting deferred, start over with a short list of numbered filters, three cleaning rhythms, a written method, and a signed sheet. For kitchens that want to shorten the degreasing step itself, the PowerDe cleaning equipment range and the engineering services behind it can be discussed directly with the Shenzhen PowerDe Automation Precision Equipment team.
