Map the machine before choosing the method
Walk the press and mark three things: every opening in the enclosure, every lubrication point, and every electrical or sensor connection. Ways, guide surfaces, bearing housings, grease nipples, encoder cables and junction boxes are the points that decide whether factory machinery degreasing with heat and pressure is safe here. On older machines, seals and gaskets have already taken years of thermal and mechanical cycling, and a jet aimed near them can push past a lip seal without any visible change that day.
Get the medium's actual figures from the supplier
Ask for the delivered steam temperature and pressure at the nozzle, not at the boiler, and for the difference between dry-steam and wet-steam output. A machine tool steam cleaning setup that lets the operator select the drier mode for oily films and keep the wetter mode for open panels is materially easier to control around a press than a single-mode machine. If the supplier cannot state those figures, treat that as a reason to stop the specification until they do.
Confirm on paper which machine components the manufacturer of the press will accept cleaning on, and whether any of it affects the machine's warranty or its calibration status.
Protect what the cleaning does not touch directly
Run-off, vapour and displaced oil go further than the jet. Coolant and cutting-fluid residue lifted from the exterior will travel along the frame to the base, into cable ducts and onto the floor. Vapour condenses on control cabinets and on the reading surfaces of scales and encoders. Plan masking and a collection route for the run-off before the first pass, and confirm where that liquid is permitted to go.
Any oil that is softened but not removed will relocate into a guide or a seal rather than disappear. A single cleaning pass that leaves residue behind is worse than no pass at all, because the residue ends up somewhere harder to reach.
Test before the schedule changes
Clean one machine, on one side, on a hidden area, and then check the machine's behaviour: noise, way movement, lubricant condition, and whether any alarm or encoder fault appears afterwards. Record that result. If the press runs without incident, extend the method and write it into the maintenance plan with the figures and the masking steps in it. If anything changes, stop and treat cleaning as the change that caused it.
Send the press type, its age, the enclosure layout and the soil you are dealing with to PowerDe cleaning equipment and ask them to recommend the mode, pressure and accessories for that machine rather than a general workshop answer.
