1. Map every piece of equipment that needs degreasing
Start with a list, not a quote. Walk the line and record each item by name, location and size: exhaust hood and filters, duct access points, range and stovetop surfaces, griddles, fryer housings and the gap behind them, ovens, steam tables, splashbacks, shelving, and the floor strip between the line and the wall. Note what each unit is made of — stainless, painted steel, aluminium filter mesh, gaskets and plastics — because material determines how much heat and pressure a surface can take.
For each item write down how often it is cleaned now, who cleans it, and how long that takes. This is the baseline you will compare against later. If a hood filter is pulled monthly because the task needs two people and a sink full of chemicals, that fact is part of the assessment, not background noise.
2. Classify the soil before choosing a method
Grease in a working kitchen is not one substance. Fresh splatter is soft and water-soluble. Older residue has polymerised — it has been heated, cooled and heated again until it hardens into a varnish that brushes and general-purpose detergents barely shift. Look at surfaces you rarely touch: the top edge of the hood, the wall behind a fryer, the underside of a shelf. That is where the oldest film sits, and it tells you what the equipment must be capable of.
This distinction decides the specification. Light, fresh soil can be handled by a routine wipe-down. Polymerised grease needs sustained heat to soften the film so it can be lifted. Where the residue has built up over months, plan on a two-stage approach: an initial deep removal to reset the surface, then a shorter recurring routine that keeps it from returning to that state.
3. Measure the space, the utilities, and the access route
Kitchen equipment is chosen as much by the room as by the soil. Record the following, because each one filters out machines that would otherwise look suitable on a datasheet:
- Clear width of doorways, and whether the route crosses a dining area, a corridor or a step
- Available power at the point of use, and whether the outlet is on a circuit that also carries cooking equipment
- Access to water, and where waste water can be discharged legally
- Storage space for the machine when it is not in use
- Whether the work must happen while the kitchen is closed, or during a quiet service window
A narrow service corridor rules out anything bulky. A site with no water connection near the line pushes you toward a machine with its own tank. A fixed unit such as the Fixed Steam Cleaning Machine PowerDe HW02 is a candidate where there is a stable 220 V supply and the machine will stay in one place — the page lists 6 kW heating power, 160° steam temperature, 0.8 MPa vapour pressure and an 80 L SUS304 tank, in a footprint of 1,200 × 800 × 1,200 mm including handles. Where the kitchen layout is tight and the cleaning route moves between zones, a hand-pushed or mobile unit is the better fit.
Ask the supplier to confirm these figures against the configuration you would actually receive, and to confirm that the model is offered for kitchen use. The product page on the PowerDe site describes vehicle exterior cleaning, interior work and engine-compartment cleaning; the kitchen and central-kitchen applications come from the customer's marketing directions and are not yet listed on that page.
4. Check what the machine can deliver against grease, in your conditions
Three numbers carry most of the weight: steam temperature, pressure, and how long the machine holds them. Heat is what breaks the bond between polymerised grease and stainless; pressure is what lifts the softened film off a textured surface or a welded joint. A machine that produces steam once and then loses it as the tank cools will look fine in a demonstration and fail across a full line.
Ask for a test on your own worst surface, not on a clean sample panel. Bring a removed hood filter or a section of splashback that has not been treated. Watch what the operator has to do to get a result: how long they hold the nozzle in place, whether they still need to scrub afterwards, and how much liquid ends up on the floor. Also ask which mode they would use — dry steam leaves less runoff and suits electrical housings and overhead work, while wet steam carries more heat into a heavy deposit. On machines that switch between the two, the useful question is how fast the changeover happens and whether both modes are usable in one session.
5. Assess the water, chemical and waste implications
Write down how the site handles waste water today and what it is permitted to discharge. Traditional pressure washing of greased equipment pushes a large volume of oil-laden water into the drainage system. High-temperature steam is a low-volume method, which reduces runoff and, in most kitchens, reduces the amount of chemical degreaser needed — an advantage where strong chemicals cannot be used near food-contact areas or where ventilation is poor.
Still, plan for the waste you will create. Grease lifted from a hood has to be captured on cloth or in a tray and disposed of as the site's regulations require. Confirm the water source the machine expects — the HW02 page specifies a tap-water inlet with a 4-point internal-tooth joint (1/2 inch) — and check whether your supply needs any treatment.
6. Look at downtime, scheduling, and disruption
A cleaning plan competes with service hours. Decide in the assessment what you can realistically take out of production: one hour after close, a Sunday morning, a section at a time. Then check whether the machine supports that pattern. Heating-up time, tank capacity, and how long the machine works before it needs a refill or a recharge all determine whether a job fits inside your window. Battery-powered units extend reach where sockets are far away; a mains-powered fixed unit removes that question but limits where the machine can work.
Also record what has to be protected during cleaning — electrical cabinets, gas controls, filters, anything with an opening. Any method you adopt needs a written pre-task step for this. Ask the supplier which protection functions the machine includes; the HW02 page lists leakage, short-circuit, high-temperature, high-voltage and water-shortage protection, and you should confirm the full set for the configuration you are quoted.
7. Record the safety and compliance points that shape the method
Note the site's own requirements before you evaluate any equipment: fire and hygiene inspection rules that govern hood and duct cleaning, the documentation your insurer or environmental authority expects, and the training records your staff already hold. Steam works at a temperature that can injure, so the assessment should specify who is allowed to operate the machine, what personal protective equipment they wear, and how the task is signed off. If your hood and duct cleaning is contracted out, decide clearly which surfaces stay in-house and which stay with the contractor, so the new equipment supplements the contract instead of clashing with it.
8. Set the pass/fail criteria before you talk to a supplier
Turn the assessment into a short list of requirements, and give that list to every supplier you approach. A useful form of it:
- Surfaces to be cleaned, and the soil grade on each
- Maximum time per session, and the number of sessions per week
- Power, water and drainage constraints at the site
- Access route and storage footprint limits
- Chemical limits and waste-water rules
- The result you will accept, stated as a physical condition you can see
Define that last point honestly. "Grease removed" is not a criterion. "Filter mesh visibly clear of the dark film, and no residue returns on a white cloth drawn across the surface" is. Then ask for the trial against that wording.
9. Turn the findings into a written cleaning process
The deliverable from a site assessment is a document your team can follow: what is cleaned, how often, by whom, with which machine and which mode, with what protection steps before starting, and what confirms the job is done. Attach the equipment reference to each task so a new operator knows exactly which unit and nozzle the step refers to.
Review the document against your own line. If a step is not doable inside the time you actually have, it will not survive the first busy week. Where the process needs a custom configuration — a fixed installation for a central kitchen, a mobile unit for a multi-site operator, or an equipment specification written to your constraints — customized steam cleaning equipment support is listed under the Solutions section of the PowerDe site, with contact details on the contact page.
What to do next
A good site assessment ends with three things: a list of surfaces and soil grades, a set of site constraints that no equipment can change, and a written pass criterion for the result. Take those to the trial, test on your own fouled parts rather than a demonstration panel, and keep the written process with the machine. Buyers comparing options can start from the Cleaning Equipment Series listing, then confirm the specification and intended use for the exact model with PowerDe at sales@powerde.net before any purchasing decision.
