Aerospace components often combine complex geometries, precision-machined surfaces and demanding cleanliness requirements. Machining and forming operations can leave behind oils, greases, emulsions, swarf and particulate contamination in bores, recesses and other difficult-to-access areas. Removing this contamination consistently requires a controlled cleaning process designed around the component and its contamination type.
The Universal 81C/P, a Made-in-India solvent-based cleaning system from Ecoclean, combines multiple cleaning and drying processes within a closed work chamber. This allows the process to be configured according to the specific cleaning requirements of the component.
Universal 81C/P – a solvent based, made-in-India machine built for aerospace component cleaning.
The Challenge With Treating Component Cleaning as a Single Step
A lot of cleaning equipment on the market is built around one process spray or immersion or ultrasonic and asks the part to fit whatever that one process can do. Aerospace components rarely cooperate with that approach. A single part might need aggressive oil removal from a machined bore, gentle handling on a thin-walled section, and 100% dry before it goes anywhere near assembly or inspection. Ask a single-process machine to do all of that and you either under-clean the difficult areas or over-process the delicate ones.
The Universal 81C/P addresses these requirements through a combination of immersion and spray cleaning, high-power Injection Flood Washing (IFW), vapour degreasing and controlled drying. Ultrasonic cleaning can also be incorporated as an option where the application requires it.
Process Technologies Integrated in the Universal 81C/P
The Universal 81C/P is a solvent-based, made-in-India machine engineered specifically for aerospace component cleaning. Rather than relying on a single wash step, it runs parts through a defined process chain:
- Injection flood washing: drives cleaning fluid directly into channels, bores and recessed features that a spray simply can’t reach.
- Spray cleaning: handles broader surface contamination efficiently before finer processes take over.
- Ultrasonic cleaning: uses cavitation to support the removal of fine particulate contamination from complex component geometries., the same principle we have covered indepth on our ultrasonic cleaning technology page.
- Vapour degreasing: uses solvent vapour to support the removal of residual oil and filmic contamination, particularly in complex geometries.
- Intermediate drying: Supports controlled drying between process stages.
- Vacuum drying: supports controlled and thorough drying, including components with blind holes and complex geometries.
The system’s closed work chamber also incorporates closed-loop filtration, double filtration during solvent filling and emptying, bag and candle filtration, and online vacuum distillation for solvent treatment.
Running a part through this full chain, rather than a single pass, is what makes the difference between a component that looks clean and one that actually meets a documented cleanliness specification.
Why the Numbers Matter as Much as the Process
A cleaning system only earns its place on an aerospace production line if it performs consistently, shift after shift, without becoming a maintenance burden or a cost center.
That’s where the Universal 81C/P’s operating profile does the real talking:
- Best Millipore results: the particle-count testing method most aerospace and precision manufacturers rely on to verify a part is genuinely within spec, not just visually clean.
- Best oil cleaning efficiency: built specifically around the tough oil and cutting-fluid residues common in machined aerospace hardware.
- Low energy consumption and low running cost: the process chain is engineered for efficiency, not just cleaning power, which matters once a machine is running full production shifts.
- High uptime: a machine that’s down for repairs isn’t cleaning anything and aerospace production schedules don’t leave much room for that.
- Maintenance friendly: designed so routine upkeep doesn’t turn into a full production stoppage.
- Cleaning of multiple metals: one machine that handles titanium, aluminum, nickel-based alloys and other aerospace materials, instead of needing separate equipment per material type.
Where This Fits Into Your Process
If your current cleaning line is handling aerospace parts through a process that was originally designed for automotive or general industrial components, it’s worth asking whether it’s actually verified against aerospace-grade cleanliness requirements, or just assumed to be good enough. The two aren’t the same thing, and the aerospace sector doesn’t leave much room for assumptions.
Application-Specific Cleaning and Validation
The appropriate cleaning process depends on factors such as contamination type, component geometry, material and required cleanliness level. For aerospace applications, process performance should therefore be established using actual components and defined cleanliness requirements.
Ecoclean India can support this process through application-specific cleaning trials and cleanliness evaluation at its Technology Centre in Pune, helping manufacturers assess the suitability of the selected cleaning process before production implementation.
Our Universal 81C product page has the full technical specifications and our aerospace applications page covers how we’ve approached cleaning across other component types in this sector. We also run cleaning trials at our Pune Technology Centre so you can see Millipore-verified results on your actual parts before committing to equipment.

Frequently Asked Questions
- What makes the Universal 81C/P different from a standard solvent cleaning machine?
A. It doesn’t rely on a single cleaning method. It combines injection flood washing, spray cleaning, ultrasonic cleaning, vapour degreasing and vacuum drying in one process chain, so different contamination types and part geometries are handled by the stage best suited to them, rather than forcing everything through one generic wash cycle. - Is the Universal 81C/P suitable for materials other than aluminum?
A. Yes. It’s built to clean multiple metals, including titanium alloys, nickel-based superalloys and aluminum, which is important given how many different materials show up across a single aerospace production line. - How is cleanliness actually verified on parts run through this machine?
A. Through Millipore particle-count testing, the same method most aerospace manufacturers use to confirm a component meets a documented cleanliness specification rather than just appearing clean. We run this testing at our Pune Technology Centre before a customer commits to a configuration. - Does a multi-stage cleaning process like this increase running costs significantly?
A. Not in practice. The Universal 81C/P is engineered for low energy consumption and low running costs alongside high uptime, so the added process stages don’t translate into a heavier operating burden. - Can this machine handle both external surface contamination and hard-to-reach internal features?
A. Yes. Injection flood washing and ultrasonic cleaning are specifically included to reach internal channels, bores and recessed geometries that spray cleaning alone can miss, while vacuum drying ensures those same hard-to-reach areas end up dry, not just clean.
