When a plant asks us to run a cleaning trial on oil residue, the request usually arrives in one sentence: our machines are covered in oil, can your equipment remove it? That question cannot be answered yet. Two jobs described in exactly the same words may need different steam settings, different attachments, or even a different machine class. A cleaning trial is a short engineering test, and like any test it only produces a usable result when the conditions are defined in advance. Here is the information we ask you to prepare before we schedule one.
1. The residue type and how long it has been there
"Oil" covers a wide range of soils that behave very differently under heat and pressure. Fresh cutting fluid flushed across a machine bed is soft and mostly water-soluble. Hydraulic oil that has sat on a warm housing for months has begun to polymerize into a tough, varnish-like film. Grease mixed with abrasive dust forms a grinding paste in corners and seams. Tell us what the fluid is — cutting fluid, hydraulic oil, way oil, grease, or a mixture — whether it is fresh or baked on, and roughly how long it has been on the surface. If you have a safety data sheet for the fluid, include it; the additive package matters more than most buyers expect.
2. The substrate and everything sensitive nearby
The material being cleaned sets the limits. Bare steel and cast iron tolerate aggressive steam and pressure. Aluminum, brass, and plated surfaces are softer and can be damaged by a nozzle held too close for too long. Painted panels, decals, cable labels, open bearings, sensor connectors, and electrical enclosures all react differently to high-temperature steam, so we need to know what is on or next to the part. Send photographs of the surface before cleaning, and mark any area where a finish, coating, or marking must survive the process.
3. Geometry and access
Flat, open surfaces are the easy case. Oil hides in blind holes, weld seams, bolted joints, way covers, and the undersides of frames, and those areas decide the nozzle, the extension wand, and the dwell time the job needs. Describe the size of the area to be cleaned, whether the part stays in place or comes off the line, how close the operator can get, and whether there are overhead or confined-space restrictions. A photo taken from the position the operator would stand in tells our engineers more than a written description.
4. Utilities and access at the cleaning location
Before the trial, confirm what the location can supply. Check the available power — a fixed unit such as the PowerDe HW02 runs on 220 V with a 6 kW heater and takes a tap-water inlet — and note whether compressed air, drainage, and floor space for the machine and its hoses are available. If cleaning happens in a parking area, a basement garage, or a shared service bay, access and cable length become part of the machine selection. For mobile work, battery runtime and recharge time matter just as much as cleaning power.
5. Production constraints and a written pass criterion
A cleaning method that works but takes six hours will not be adopted. Tell us how much downtime the trial can use, whether cleaning is done in place or at a fixed station, and any rules about water runoff, solvent use, or work during production hours. Then define what "clean" means in terms you can check on the spot: a visible grease-free surface, a wipe test, or a residue limit your quality team already applies. Without a written pass criterion, the trial ends in an opinion rather than a decision.
What to send before the trial
A short, complete request saves weeks of back and forth. Include:
- Photos of the soiled part and its surroundings, taken from the operator's working position
- The fluid type and how long it has been on the surface, with an SDS if available
- The substrate material and any sensitive components nearby
- Available utilities, downtime, and your written pass criterion
With those details, we can match industrial steam cleaning equipment to the job instead of guessing, and select the machine, attachments, and steam settings the trial will actually test. For heavy, polymerized grease, heavy grease removal equipment in the high-temperature, high-pressure class is usually the starting point; for fresh cutting fluid, a shorter cycle with different settings is often enough.
What a good trial leaves behind
A well-prepared trial does not end with a demonstration. It ends with a written procedure: which surface was cleaned, which nozzle and distance were used, how long the steam dwelled, how much water and time the cycle took, and whether the result met your pass criterion. That procedure is what you can hand to a shift team and repeat next month. If your oil-stain problem fits the description above, send us the details in the checklist and we will help you set up customized steam cleaning equipment and a trial plan around your line, your downtime, and your definition of clean.
