Recover Performance—Reduce Fuel Burn—Protect the Asset.
Modern fleets operate in dust, salt and soot. Deposits in the core erode EGT margin, raise fuel burn and compress maintenance windows. Engine washing turns that curve around on-wing - safely, repeatably, and in line with OEM procedures, so aircraft return to plan with less variability and better economics.
Engine Washing as a Performance Lever
Each flight leaves a residue. Dust, salt, soot and unburned fuel build up on compressor and turbine surfaces, slowly eroding efficiency and shrinking EGT margin. At some point, operators feel it as higher fuel consumption, reduced thrust margin or earlier shop visits.
Engine washing with the right combination of chemistry, hardware and procedures reverses this trend:
- Restores compressor efficiency and EGT margin
- Reduces specific fuel consumption over the next operating window
- Extends time-on-wing and defers shop visits
- Supports emissions and sustainability targets
RH Aero brings together OEM-developed foam wash technology and robust recovery systems into one integrated business area, standardized for airline, MRO and business aviation operations.
Outcomes You Can Measure
Track what matters and tune cadence accordingly:

Environmental Compliance (captured/treated effluent)
Use Cases Across the Engine Lifecycle
Engine washing with GEs 360 Foam Wash and AeroJetVac supports multiple operational scenarios:
- Line Maintenance & Overnight Stops – Planned washes during A-checks or overnights to maintain performance.
- High-Contamination Routes – Operations in desert, coastal or industrial environments with elevated particulate loads.
- Performance Recovery Campaigns – Targeted washing programs when fuel burn and EGT trends show degradation.
- Pre-Shop and Post-Shop Events – Supporting inspection quality and baseline conditions before or after shop visits.
RH Aero works with customers to define wash intervals, engine applicability and integration into existing maintenance programs.
Benefits for Operators and MROs
Fuel Burn and CO₂ Reduction – Cleaner cores help reduce specific fuel consumption over the following cycles, supporting cost and sustainability targets.
Recovered EGT Margin – Removing deposits helps recover temperature margin, enabling longer on-wing periods and more flexibility in deployment.
Extended Time on Wing – When combined with good monitoring and planning, washing can defer shop visits and reduce unplanned removals.
Predictable Turn Times – Standardized wash procedures and equipment reduce variability and keep aircraft on schedule.
Cleaner, Safer Worksites – Closed-loop recovery and controlled processes improve housekeeping, worker safety and regulatory alignment.
Why RH Aero for Engine Washing?
RH Aero’s Engine Washing business area combines:
- OEM-Aligned Technology – GEs 360 Foam Wash brings OEM-developed chemistry and procedures into daily operations, supported by RH Aero implementation expertise.
- Integrated Hardware Ecosystem – AeroJetVac sits alongside our engine stands, COBRA systems and ground support equipment, creating a continuous, compatible workflow around the engine.
- Global Support Network – Training, spare parts, calibration and service from a global network of service centers.
- Documentation and Training – Clear work instructions, checklists and training materials that maintenance teams can use under time pressure.
- Ready. Reliable. Relentless. – A single partner that takes responsibility from specification and commissioning to lifecycle support.
Engine washing is no longer a side activity—it is a structured performance tool. RH Aero’s Engine Washing business area brings the right combination of OEM technology, engineered hardware and global support to make it work.
Engine washing (also called compressor washing or on-wing engine cleaning) removes dust, salt and soot from internal gas-path surfaces to recover performance and fuel efficiency.
Intervals depend on route mix, environment and trend data. Many operators align washes to line checks or trigger recovery campaigns based on EGT and fuel-flow trends.
Yes—cleaner cores typically require less fuel to achieve the same thrust, supporting cost and CO₂-reduction goals.
When performed to OEM-aligned procedures with controlled application and effluent capture, washing is a proven, airworthiness-compliant maintenance task.
Yes—processes can be configured for gate, stand or hangar with closed-loop containment to meet airport and environmental requirements.
