A cleaning trial on a commercial stovetop usually fails before the machine is switched on. The kitchen is still running, the staff have not agreed who does what, and there is no record of what the stovetop looked like beforehand. When the trial ends, nobody can say whether the range improved or merely moved. Preparation is what turns a demonstration into a purchasing decision, and the person who runs it will be standing next to the equipment when the manufacturer asks what happened.
Agree the scope of the trial before anyone touches a surface
Write down which items the trial has to cover. A commercial stovetop is rarely one object: the top plate, the splashback, the control knobs, the drip tray, the shelf beneath and the floor directly in front of it are handled with different tools and take different amounts of time. A trial that starts with the stovetop and quietly expands into the griddle and the range hood cannot be compared with anything afterwards.
Decide the reference point. In most kitchens the comparison is not against a laboratory result but against the routine the team already performs. If a scrub and wipe with a detergent bucket currently takes thirty minutes per range, that is the figure the trial should beat, and it should be timed on the same model of range, on the same shift length, with the same number of people. If the current routine is not being timed, time it once before the trial; a trial run against an estimated number is a trial run against nothing.
Choose the surfaces that show the difference
Staff should pick surfaces where the soiling is representative rather than convenient. The edge where the top plate meets the splashback, the shadow of a burner ring, and the underside of the control panel accumulate the heaviest film, and they are exactly the places a cloth gives up on. Cleaning only the flat open area of a range flatters the machine and hides the problem the kitchen actually pays for.
One surface should be deliberately left untreated during the trial, photographed, and cleaned last. That untreated surface is the control. Without it, the difference between the machine's result and a good day's hand cleaning is a matter of opinion.
What the team needs in place physically
Before the first pass, the crew should have the following ready and in the location where it will be used:
- A clear path from the water supply and the power point to the stovetop, with the floor dry along that path. Wet floors in a live kitchen are the most common reason a trial is stopped halfway.
- The water inlet connection listed on the equipment, checked against the kitchen's existing tap fitting, so a missing adapter does not consume the first hour.
- Confirmation that the circuit serving the trial area can carry the machine's working voltage for the full session, and that no other high-draw appliance shares it during the trial.
- A written list of which parts of the stovetop are electrical, which are gas-connected, and which carry safety labels that must not be soaked or scraped.
- Personal protective equipment for the operator running the steam lance, plus a second person assigned to keep the floor clear and to hold the light on the surface being worked.
- A phone or camera on a fixed mount, so before and after photographs are taken from the same angle and cannot be argued about afterwards.
Choose the mode the trial is testing
A machine that switches between dry steam and wet steam needs to be trialled in both modes, otherwise the result belongs to a setting rather than to the equipment. Dry steam suits baked, dry grease that has been reheated many times. Wet steam suits loose residue and the bulk of the film. Running one mode for the whole trial and then reporting on the machine leaves the buyer without the information needed to specify a model.
Record the mode used on each surface, in the same order on each range. If the kitchen handles griddles, fryers or exhaust hoods in the same programme, those items belong to a separate trial with its own record; a stovetop result carried across to a hood is a guess.
What to record as the trial runs
Four columns on a clipboard are enough: time started, time finished, refills of the water tank, and any point where the operator stopped and why. Add the number of staff involved and the part of the shift the trial fell in. A trial run during the pre-service rush and a trial run after closing are different events, and the record should say which one the reader is looking at.
Ask the operators one question in writing at the end of the session: on a scale of acceptable to unacceptable, how did the physical effort compare with their normal routine. Their answer carries more weight in the purchasing meeting than any observation the equipment supplier can offer.
Matching the trial result to equipment that fits the kitchen
Once the trial is complete, the record answers the questions that matter for specification: whether a fixed unit plumbed at the cleaning point is practical, or whether a unit that moves between ranges suits the layout. PowerDe's cleaning range includes fixed and mobile configurations. The Fixed Steam Cleaning Machine PowerDe HW02 page states 220 V operation, a 6 kW heating element, a steam temperature of 160°, a vapour pressure of 0.8 MPa and an 80 L SUS304 tank, together with dry and wet steam modes and protection covering leakage, short circuit, high temperature, high voltage and water shortage; confirm the figures for the configuration being quoted before ordering.
Where a kitchen is evaluating commercial kitchen stovetop degreasing as part of a wider programme rather than one range, the same trial record supports that decision. If a site is assessing several areas at once, the trial should be repeated area by area against the same reference point, not run as one long session that mixes surfaces and shifts.
Bring the completed record, the photographs and the operator's written answer to the supplier conversation. A buyer who arrives with the trial data specified their kitchen's requirements; a buyer who arrives with enthusiasm alone will be quoted for the standard configuration.
