A cleaning trial in a commissary or central kitchen usually lasts a single shift, but the decisions made around it can shape a year of purchasing. Before the machine arrives, the people who will operate it, maintain it, and sign off on the results should already know what the trial is meant to answer. The steps below cover how kitchen and facility staff can prepare commissary kitchen equipment for a cleaning trial that produces a usable answer.
Define what the trial must prove
Write down the question the trial is answering before any equipment moves. Typical questions look like: can heavy grease on a hood baffle be removed without taking the hood apart; can a stovetop or grill be degreased without interrupting prep; can the floor clean-up done at end of shift be shortened. A written question lets you judge the result, instead of deciding afterwards whether the demo looked impressive. Assign one person to record outcomes, and agree in advance what counts as a pass.
Walk the kitchen and mark trial zones
Choose a small set of surfaces that represent the harder cleaning jobs, and mark them. A useful set for a commissary includes:
- Range hood baffle or filter, where grease has been accumulating between cleanings
- Stovetop, grill, or griddle surround, where burnt-on residue builds up daily
- Floor next to the cooking line, where grease and water collect together
- Exterior of a steam-jacketed kettle, mixer, or conveyor oven base
Pick zones that staff clean anyway, so the trial does not require extra production time. Photograph each zone before cleaning with the same angle and lighting used after cleaning. Those before-and-after photos are the evidence you compare during the review.
Confirm services and clear the area
A fixed machine needs a power source near the trial zone. Before the trial, have a facility technician confirm outlet ratings, circuit capacity, cable routing, and whether wet-floor work near those outlets needs a lockout or a cover. Do not assume an existing circuit can carry added equipment. For a battery-fed machine, confirm where it can be parked and charged without blocking aisles.
Clear the floor path from the water supply to each trial zone. Remove carts, floor mats, and crates. Move or cover food, utensils, and packaging that could be splashed. Post a wet-floor sign before cleaning starts, and schedule the trial outside peak prep times so staff are not working around the operator.
Check the machine's own conditions with the supplier
Ask the supplier for the specification sheet of the exact model coming to the trial, and read it with your facility technician. The parameters that matter for kitchen work are water supply type and connection, required voltage and power draw, tank capacity, steam temperature and pressure, and whether the machine runs continuously or pauses to reheat. Model naming on published listings is sometimes inconsistent, so confirm the model name and figures against the machine in front of you rather than a brochure.
Ask whether the unit is designed for dry steam, wet steam, hot water, or a combination, and what changes between modes. That single answer determines whether it suits surface degreasing, floor work, or both. If a food-contact area is in scope, ask the supplier in writing what the machine can and cannot be used on. This article is about preparing your own equipment and site, not about claiming results.
Brief the staff who will operate it
The trial should be run by staff who will run the machine after purchase, not only by the vendor's demonstrator. Before starting, review personal protective equipment, safe distance from the nozzle, what must never be sprayed (electrical panels, open food, floor drains in a way that sends grease into them), and the shutdown steps. Agree who supervises. If the machine has protection features, ask the demonstrator to show what they do and how the operator resets the unit.
Decide what data you will record
Prepare a simple record sheet before the trial. Record for each zone:
- Time spent cleaning, including setup and clean-down
- Whether a chemical product was used, and how much
- Rework needed: scrubbing, repeating a pass, disassembly
- Staff effort, in plain words, from the person operating the machine
- Any interruption to production, however short
One sheet per zone, filled in as the trial runs, gives you a comparison against the current method instead of a memory of it.
Run the trial, then compare methods
Clean each marked zone and photograph it. Then have the operator compare the result with your current method on a similar surface elsewhere in the kitchen, so the difference is visible on the same shift. A trial that only shows the new machine in isolation invites optimistic conclusions.
If you are evaluating a fixed machine such as the HW02 fixed steam cleaning machine from PowerDe, note that its published listing describes vehicle and exterior cleaning applications. Use the trial to test whether it suits your kitchen surfaces at all, rather than assuming it does. For comparison, the PowerDe cleaning equipment series also lists mobile and hand-pushed units, which may fit a kitchen layout better than a fixed unit. Ask PowerDe directly, at contact, which configuration is offered for food-service use before treating any model as kitchen equipment.
Review the results with a decision date
Hold the review while the trial is fresh, with the operator, the supervisor, and the person who owns cleaning contracts in the room. Compare recorded times, chemical use, and rework against your current method. If the trial answered your opening question positively, move to a written quote and a defined pilot period. If it did not, note what failed and ask the supplier what would change. Either way, set the decision date at the review, so the trial does not quietly lapse.
