Grease on kitchen equipment is easy to ignore and expensive to remove. It starts as an oil mist from frying and grilling, settles on hoods, filters, panels and the tops of cooking equipment, and over weeks turns into a hard, sticky coat that a sponge and detergent will not shift. Before you buy any equipment to deal with it, you need a way to judge whether steam cleaning is actually the right answer for your kitchen — and a way to test it on your own surfaces rather than on a showroom floor.
What makes kitchen grease hard to remove
Cooking oil changes as it is heated and then left to cool. Each hot cycle makes the deposit thicker and stickier, so the same surface that wipes clean on day one needs scraping by month three. Two properties decide how any method will perform: the deposit needs heat to soften before it will release, and the surfaces involved are usually stainless steel, painted panels, electrical housings and filter mesh — materials you cannot simply blast with water without creating a mess, a slip hazard or a wet electrical area.
That combination is exactly what central kitchen degreasing equipment is built for. Steam carries heat in a compact, controllable form, so the deposit is softened at the surface rather than soaked, and the operator controls how much moisture reaches the area in front of them.
Evaluate steam against the method you use now
Score the option you already run — manual scrubbing with detergent, a hot-water pressure washer, or an outsourced contractor per visit — against five questions:
- Does it remove set grease, or only fresh grease? If your current method only works right after cooking, the coat between cleans keeps building.
- How much water ends up on the floor? Flooded floors mean downtime, drainage work and slip risk in a live kitchen.
- Can it clean near electrical and insulated parts? Many kitchen surfaces cannot take a heavy water flow.
- How long does one hood and filter set take? Time is the cost most operators underestimate.
- Can you run it on a short cycle, in-house? A method that only works once a quarter with a contractor leaves the deposit to rebuild in between.
Check the machine's actual parameters, not the marketing claims
Ask the supplier for the specification sheet and read four numbers. Steam temperature and supply pressure decide whether set grease will release. Heating power and tank capacity decide how long the machine can work before it needs a break. Water supply and power requirements decide whether your kitchen can actually run it. Protection features decide whether a safety officer signs it off for indoor use near cooking equipment.
As a reference point, the PowerDe HW02 steam cleaner is a fixed 220 V unit with 6 kW heating power, 160°C steam temperature and 0.8 MPa vapour pressure from an 80 L SUS304 tank, with a switch between dry and wet steam and an integrated vacuum function. It lists leakage, short-circuit, high-temperature, high-voltage, water-shortage and high-voltage-explosion protection. Its own product page describes vehicle exterior cleaning, interior work and engine-compartment cleaning, so the kitchen applications are something to confirm directly with the manufacturer against your surfaces before you commit — that confirmation step is part of a proper evaluation, not an optional extra.
Run a real trial on the dirtiest item you own
Do not trial the machine on a clean panel. Pick the worst hood filter you have, plus one section of the hood interior and one piece of cooking equipment with visible build-up, and run the trial against a written standard: what "clean" looks like, how long it takes, and how much water ends up on the floor. Then repeat the same trial with your current method on a comparable surface so the comparison is honest.
Record four results from the trial: minutes per item, whether any area needed a second pass, the amount of runoff, and whether staff could operate the machine after a short briefing. If a supplier will not let you trial on your own equipment, that is a reason to keep looking.
Cost it as a cycle, not as a purchase
Take the hourly labour rate of the person doing the job, multiply by the trial time, and add consumables, water, energy and any downtime during the clean. Then multiply by how many cycles per month your kitchen needs. Compare that monthly figure with what you pay a contractor per visit and with the cost of the current method's downtime. Steam usually wins on this comparison only if you use it often; a kitchen that runs one deep clean a quarter will not see the case change, while a kitchen that cleans filters weekly will.
Make the decision on evidence you can show
Write the trial results up as a one-page record with the four measured outcomes, the specification sheet from the supplier, and the written confirmation about your specific surfaces. That single page answers the questions a manager, an insurer or a franchisor will ask, and it becomes the baseline for the next review. If you want that record to cover your layout and volumes rather than a generic specification, PowerDe also works on customised steam cleaning equipment, so you can put your kitchen in front of the engineering team and get a configuration proposal to assess instead of a catalogue sheet.
