A contract cleaner working a chain of restaurants is usually handed the same instruction at every site: wipe the stainless down at the end of service. The instruction is not wrong; it is incomplete. Stainless steel in a working kitchen does not stay the same between two shifts. What reads as a clean, bright surface one hour may be a layer of re-deposited oil film the next, and by the end of the week that film has thickened in the corners, behind the splashbacks and along the seams. The documentation problem for a service provider is therefore narrower than "did we clean it". It is: what was on the surface when we started, what we did to it, what we did not touch, and how the next shift can tell the difference.
The records below are written from the contractor's side. A kitchen operator who keeps their own records will want a slightly different form, and the site's food-safety paperwork always outranks a cleaning contractor's checklist.
1. Surface inventory before any shift sheet is written
List the stainless you are contracted for by item, not by room. "Kitchen — stainless — daily" cannot be audited and cannot be handed over. A usable inventory names each surface and records four things against it: where it is, what finish it has, what is attached to it, and how it is normally touched.
In a typical line that means the tops of prep tables and their undersides, the faces and legs of the tables, the front and return walls behind the fryers and grills, the exterior of the hood and its filter frames, the vertical surfaces of ovens, kettles and extractor cabinets, the shelving and its uprights, the sinks and drainer boards, the trolley frames, and the low plinth where a floor meets a stainless unit. Add the parts people forget: handles, push bars, control panel bezels, the gap between a worktop and a wall, and the underside lip of a splashback where oil runs and stops.
Record the finish on each item. Most kitchen stainless is a brushed or polished sheet finish, but brushed is not one thing: a coarse satin grain holds a film differently from a mirror polish, and a decorative or coloured panel next to the stainless behaves differently again. Record whether a surface is welded or mechanically fixed, because a welded seam with a filled root behaves differently from a rivet or screw line, and whether it is hollow tube or solid. Note which items the site's own staff touch constantly, because finger oil is a separate deposit from cooking grease.
2. Classify the deposit, because the deposit decides the record
Three deposits appear on kitchen stainless, and a contractor who logs only "cleaned" is not telling the client anything useful.
- Fresh splash — warm oil, water and food particulate from the current service. Loose, mobile, removable with a cloth and detergent.
- Re-deposited film — aerosolised cooking oil that has drifted and settled on cooler vertical surfaces away from the appliance itself. Thin, spread over a wide area, and the reason a "clean" wall looks dull and slightly tacky the next morning.
- Built-up and polymerised residue — repeated heating of the film until it hardens into a dark, varnish-like layer, concentrated at seams, edges, filter frames and the upper hood face. This is what resists a cloth and what makes a shift record dishonest if it is ticked as done.
Add a fourth line where it applies: mineral haze from hard wash water or detergent residue, which looks like a stain but is not grease. A shift sheet with a deposit column turns an argument about standards into a description of a condition. It also tells the next crew which surfaces need heat and dwell time, and which need only a cloth.
3. What is out of bounds, and who signs that list
Before the first shift, produce a written exclusion list with the site's maintenance contact and get it signed. For stainless items this normally covers electrical enclosures and junction boxes, thermostat and control pods, displays and their bezels, indicator lights, cable glands and conduit entries, fan and motor housings on hoods and extractors, the interior of any appliance, gas valves and ignition assemblies on the appliances beside the stainless, sealed glass, laminated or printed decorative panels, adhesive-applied trim, and any surface with a lifted seam, corrosion staining or a previous repair. Bearings, guide rails and relubrication points on any adjacent equipment are excluded as well.
Write exclusions as operator rules, not just as a list of parts: the nozzle and cloth never directed into a panel gap, a connector housing, a fan grille or a cable entry; masking applied before the shift starts rather than judged mid-task; any item on the list confirmed again by whoever takes over the crew. Keep the signed list in the shift pack and re-issue it whenever the client changes an appliance. A contractor's exposure on a kitchen job almost never comes from a surface left dirty; it comes from a control panel that was wetted.
4. Between-shift window, sequence and dwell time
Between shifts means a fixed number of minutes, not "after service". Write the window down per site, and write the sequence inside it: dry removal of loose debris first, heat and dwell on built-up areas, lift and wipe, then a dry finish pass, then the floor directly beneath the work. Working top to bottom and back to front keeps a crew from undoing finished surfaces.
Dwell time is the variable that decides whether a hard deposit lifts at all, and it is the one almost never recorded. Two minutes of heat on a hood filter frame is a different job from twenty seconds. For the two worst surfaces on each site, log the dwell used, the number of passes, and the mode. Those three numbers are what makes a method repeatable by a second shift, and they are what you show a client when a surface needs longer than the agreed window.
5. Method per deposit, stated as a rule
Cloth and detergent remain the right answer for fresh splash and for hand-contact marks. They stop working once oil has been heated repeatedly; wiping a polymerised layer smears it and gives the surface an even, dull appearance that looks maintained and is not. Cold and warm water do not move that layer; scraping it abrades the finish, and a scratched stainless surface holds the next film faster, so scraping starts a cycle that ends with a re-surfacing bill.
For built-up kitchen grease, heat is the working principle: the oil layer is heated until it becomes mobile again, and the moving vapour carries the loosened material off the surface. A commercial kitchen steam cleaning machine set to a drier mode puts heat into a baked-on film with comparatively little free water, which matters on vertical stainless near control pods; a wetter mode then acts as a rinse once the layer has released. Where a machine offers both on one unit, write which mode is used for which class of surface, and write the distance and dwell with it. The PowerDe HW02 steam cleaner page publishes 160 °C steam temperature and 0.8 MPa vapour pressure for that model in that configuration, with a 6 kW heater, an 80 L SUS304 tank and a 220 V supply. Treat those figures as that machine's published configuration, not as a general specification, and check the data sheet for the exact unit quoted. Note also what that product page documents as its application: vehicle exterior cleaning at filling stations and parking areas, interior vacuuming and disinfection, and engine-compartment work. Kitchen stainless is an adaptation to be proved on your own surfaces during a supervised trial, not a use already documented on that page.
6. Evidence a supervisor can check in one minute
"Clean" is not a checkable criterion on stainless. Use conditions a supervisor can see without discussion, and put them in the shift sheet as pass statements:
- Grain visible and running in one direction across the surface; no streaks crossing it.
- No tackiness under a gloved fingertip on the wall behind the fryer line.
- Seams, edges, filter frames and the underside lip of a splashback free of dark build-up.
- No pooled water or damp residue in a joint, under a table top, or at the base of a leg.
- No detergent or descaler smell on a surface that touches food.
- No wetted, discoloured or blistered finish at a weld, a repaired patch or a decorative panel.
Photograph the same three surfaces at the same angle each cycle, with the site name, the date and the shift written into the file name. A rolling set of matched photographs is the only record that shows whether a deposit is being removed or merely moved. Where a surface cannot pass, record it as a finding about the method — dwell too short, wrong mode, deposit beyond the agreed scope — rather than as a missed tick.
7. The shift sheet itself
One page per site per shift, and it should carry: date, site, shift window start and end, names on the job, and the machine used with its asset number and mode. Then the work itself as named surfaces, deposit class, dwell and passes, and the pass check. Then exclusions — masked or avoided — and any exclusion that had to be entered or left, with the reason. Then the consumables line: detergent and any descaler, cloths by colour code, and the volume of water taken and how the run-off was collected and where it went. Then any exception: a damaged seam, a blistered finish, a corroded patch, a panel that could not be dried, an appliance that could not be isolated, each with a photograph and a time reported.
Two signatures close the sheet: the crew lead and the site person who accepted the work. If the client will not sign, log the refusal with a name and time rather than leaving the line blank. Keep the sheets where a food-safety officer or a fire risk assessor can be shown them, because grease build-up on kitchen surfaces is a fire question as well as a hygiene one, and a signed record of what was cleaned and to what standard is the answer most contractors do not have.
8. Colour-coded cloths and cross-contamination notes
A shift sheet is also a contamination record. Assign cloth colours by task and write the assignment on the sheet: one colour for food-contact-adjacent surfaces, another for the grease-heavy vertical surfaces, another for the floor. Record when cloths were changed, not only when they were issued. A crew that uses the same cloth on a prep top and a hood face has created a food-safety finding that no amount of visible cleanliness will clear, and the record is what proves the contractor had a rule at all.
Protect the room as well as the surface. Before any steam is generated, cover or remove dry goods, open packaging and loose chemicals, because vapour travels and settles on the coolest surface nearby. Sign the end of the line so nobody walks into a live wand. Log this in the sheet as a completed step, not as an assumption.
9. Machine records, and who services the machine
A documentation system that depends on equipment has to record the equipment. Log the unit's identity, the date it was serviced, the seals, nozzles, hoses and brushes held as spares, and the escalation route when it stops heating. The HW02 page lists leakage, short-circuit, high-temperature, high-voltage, water-shortage and high-voltage-explosion protections; name the ones that apply to the machine on site, and write the rule that a unit tripping one of them is reported and not repeatedly reset during a shift. Record the descaling routine and who owns it, since hard supply water collects inside a heater and output falls long before the machine fails outright.
Two figures that the kitchen stainless job depends on and that the mobile model pages do not publish are steam temperature and steam pressure, together with battery capacity and run time on battery variants. Do not carry numbers across between models. Where a quotation does not answer them for the exact variant being delivered, make them a written pre-order question. A crew planning a 40-minute window between shifts needs those answers, and the commercial steam cleaning equipment listing is where the published configurations for the fixed, hand-pushed and driving-style classes can be compared.
10. Frequency per surface, not per kitchen
Set the interval by surface and by what the site cooks, then defend it with the record. The wall behind a fryer and the hood face need the shortest interval. Table tops and trolley frames need a clean-before-contact routine that belongs to the kitchen's own staff rather than to the contract crew. Shelving uprights, the underside of table tops and plinth edges can carry a longer interval. A site running frying and grilling all day is not on the same schedule as one running steaming and roasting, and copying another site's interval is how a contractor ends up arguing about a deposit that was allowed to build for eight weeks.
Review the schedule against the signed sheets and one walk of the line. Where a task keeps slipping, the interval or the duration is wrong and the change belongs in the document. Where a surface still needs hard work after the scheduled method, that is a finding about the method or about the scope, and it is the argument for extending the window or changing the machine rather than for telling the crew to try harder.
11. Handover to the next shift or the next crew
The last line of the shift sheet is what the incoming crew must know: which surfaces were treated with heat, which were left for a longer dwell and why, which exclusions were entered or newly added, what consumables ran out, and whether any surface is still damp or still needs drying before the kitchen opens. Add the machine's state — tank empty, unit descaled, hose inspected — and where the unit is parked and whether it is connected to supply.
When crews change hands between contractors, hand over the surface inventory, the signed exclusion list, the matched photographs and the last twelve sheets. That pack is the difference between a new crew starting on day one and a new crew inheriting a working standard, and it is also the fastest way for a client to see what the documentation was for.
12. Getting a configuration matched to the window
Documentation makes the next question visible: whether the equipment in use fits the window the sites actually allow. A fixed unit needs power, a water inlet and a route for run-off at the point of work; a hand-pushed or driving-style unit trades those services for range and battery limits. Which class fits a site is a question of aisle widths, door heights, distance from the socket and water point, drainage, and how long the line can be out of use — not of catalogue preference.
Send your surface inventory, the signed exclusion list, photographs of the two worst surfaces on your three most difficult sites, and the shift window each client allows. Customized cleaning equipment is specified against those conditions and the duty cycle they imply, and the contact page is where that pack goes. Ask for a supervised trial on one site and record it the same way you record a shift. If the method cannot be documented to a pass check in that trial, it will not be documented on forty sites afterwards.
