AEROSPACE COMPONENT CLEANING FOR MRO AND MANUFACTURING ENVIRONMENTS
In aerospace maintenance, the cleaning process is not preparation for the inspection. In many respects, it is part of the inspection itself.
Contamination on turbine blade surfaces obscures the crack indications that fluorescent penetrant inspection is designed to detect. Residue inside hydraulic passages prevents dimensional verification. Coating contamination on composite structures affects repair adhesion quality.
Aerospace component cleaning is a critical process in its own right, with its own tolerances, its own documentation requirements, and its own consequences when performed inadequately.
The cleaning method must remove contamination to the required standard without altering the dimensional characteristics, surface condition, or coating integrity of the component. In aerospace, the cleaning process must not solve one problem by creating another.

Coverage
Abrasive cleaning that erodes a thermal barrier coating reduces the blade’s operating temperature tolerance. The component continues to be operated against its original limits while its actual condition has moved. Chemical residue inside a hydraulic assembly affects fluid, seals, and valves across thousands of operating cycles before the failure is investigated.
The specific risks include:
- ✓Coating degradation on thermal barrier, anodised, and chromate aerospace surface treatments
- ✓Chemical residue inside hydraulic, fuel, and lubrication passages affecting fluid and seal compatibility
- ✓Inspection failure from residue masking surface indications under fluorescent penetrant testing
- ✓FOD introduction from cleaning media left in open assemblies or engine bays
- ✓Documentation discrepancy where the cleaning method does not match the approved maintenance procedure
The FOD risk that most cleaning methods create
Foreign object debris is one of the most serious contamination categories in aerospace. Dry ice blasting eliminates this FOD prevention risk entirely: the CO₂ sublimates on contact and the only material to account for after cleaning is the contamination removed from the component. There is no cleaning media to track, control, or recover.
Dry ice blasting aerospace cleaning uses solid CO₂ pellets delivered under compressed air. On contact, the pellets sublimate, lifting contamination through thermal shock and rapid gas expansion. Non-abrasive. No residue. Nothing left behind.
For aerospace component cleaning, this addresses the two most significant risks conventional methods carry: non-abrasive cleaning preserves coating integrity and dimensional tolerances; zero media residue eliminates the FOD prevention risk in any environment where open assemblies or engine components are present.
Aerospace applications
Turbine blade cleaning
Combustion deposits and fouling from blades, vanes, and casings without abrasive contact on TBC systems
Compressor blades & vanes
Fouling removal without coating abrasion on compressor stages
Composite tooling cleaning
Release agent removal and surface preparation without solvent residue
Airframe surface preparation
Precision surface cleaning ahead of inspection, repair, or coating
Engine component MRO cleaning
During maintenance access windows — no drying stage, no FOD risk
Structural components
Gearbox, housings, and aerospace maintenance access components
The dry process eliminates the drying stage wet methods require. For MRO maintenance environments managing multiple components, removing that window from the aerospace component cleaning cycle directly reduces the time between maintenance access and inspection sign-off.
Turbine blade cleaning with dry ice blasting removes combustion deposits and fouling without abrasive contact on thermal barrier coatings and without chemical solvents leaving residue in internal cooling passages. The blades are cleaned to the precision level MRO maintenance inspection requires, with no secondary media to recover before the inspection can proceed.
We provide turbine blade cleaning and engine component MRO cleaning as part of aerospace component cleaning programmes for MRO maintenance operators and engine overhaul facilities.

Composite tooling cleaning with dry ice blasting removes release agent contamination and resin residue without abrasive contact on the composite substrate and without solvent residue affecting the next production cycle.
Airframe precision surface cleaning removes contamination and oxidation products for localised surface preparation without the aggressive material removal that abrasive blasting would apply to surrounding coating systems.
Ultrasonic cleaning aerospace components uses cavitation at controlled frequencies to remove contamination from all liquid-contact surfaces simultaneously, including internal channels, threaded passages, and bore geometries that surface-directed methods cannot consistently reach.
For aerospace MRO maintenance operations, the advantage is repeatability. A hydraulic manifold cleaned ultrasonically produces the same result regardless of which technician performs the cleaning or which shift it is processed on. That repeatability supports the consistent inspection outcomes approved maintenance procedures require.
Ultrasonic cleaning aerospace applications
- ✓Hydraulic fittings, manifolds, and actuator components
- ✓Fuel system components: injectors, nozzles, and distribution components
- ✓Valve bodies and flow control components requiring aircraft component cleaning
- ✓Bearing housings, lubrication components, and precision inserts
Cleaning methods that require drying time, produce inconsistent results, or generate FOD all extend the maintenance window and the MRO maintenance clock. Dry ice blasting aerospace and ultrasonic cleaning aerospace address each of these drivers: no drying stage, repeatable results, and zero media residue that eliminates post-cleaning FOD prevention verification.
No drying stage
Equipment is ready for inspection immediately after cleaning — no wait time between cleaning and sign-off.
Zero FOD risk
CO₂ sublimates completely. No media to track, recover, or verify. FOD prevention is built into the process.
Repeatable results
Process-controlled parameters deliver consistent outcomes across technicians, shifts, and components.

Aerospace component cleaning is the removal of combustion deposits, release agents, hydraulic fluid residue, oxidation products, and process contamination from aircraft and aerospace components to the standard that inspection, repair, or return to service requires. MISERV uses dry ice blasting aerospace methods for turbine blades, engine components, composite tooling, and airframe surfaces, and ultrasonic cleaning aerospace methods for hydraulic fittings, fuel system components, valve bodies, and precision components with internal geometries. Both methods are non-abrasive, leave no chemical residue, and support MRO maintenance documentation requirements across Malta and Italy.
Dry ice blasting aerospace removes combustion deposits and fouling without abrasive contact on thermal barrier coatings, without solvents leaving residue in internal cooling passages, and without generating foreign object debris. The CO₂ sublimates on contact, leaving nothing on the component or in the MRO maintenance area. This combination, non-abrasive, residue-free, and inherently FOD prevention-safe, addresses the three most significant risks conventional cleaning methods create. The surface is also immediately ready for fluorescent penetrant inspection without a drying stage.
FOD (Foreign Object Debris) is any material in an aerospace environment that could cause damage if it enters an engine or safety-critical area. Abrasive blasting generates media particles that must be fully recovered before an assembly is closed. Dry ice blasting eliminates this because the CO₂ sublimates completely on contact, there is no cleaning media to recover or account for. FOD prevention is built into the process rather than managed as an additional post-cleaning step.
Ultrasonic cleaning aerospace is used for aircraft component cleaning where internal geometries require cleaning that surface-directed methods cannot reach consistently. Hydraulic fittings, actuator bodies, valve assemblies, and fuel system components with internal bores or threaded passages are cleaned ultrasonically because cavitation acts at all liquid-contact surfaces simultaneously. Dry ice blasting aerospace is used for external surfaces, turbine blade cleaning, composite tooling cleaning, and airframe preparation. In a complete aerospace component cleaning programme, both methods are combined according to each component’s geometry.
