Exterior Dry Wash at Salzburg (LOWS)

What changes at Salzburg for exterior dry wash?

Salzburg sits at 1,410 feet elevation with a single runway, 15/33, measuring 2,750 metres. The airport operates from 06:00 to 23:00 local, with non-commercial aviation restricted to take-offs between 07:00 and 22:00 and landings between 06:00 and 22:00; VFR traffic is permitted Monday to Saturday only. A curfew closes the field from 23:00 to 06:00 except for ambulance flights, and between 22:00 and 23:00 only landings by aircraft quieter than 84 dB SEL are allowed. General aviation uses the General Aviation Center, handled by Salzburg Airport General Aviation Handling (GAC, airport-operated).

Winter is the seasonal peak: Salzburg serves as the gateway to Austrian ski areas, and Terminal 2 operates specifically to handle peak-season traffic under a separate winter timetable and coordination season. Slot facilitation applies to aircraft with more than nineteen seats because they are processed at the main terminal, where the GA area has capacity constraints; smaller business jets do not need facilitation and move through the GAC without coordination delays.

For dry wash work, the alpine environment and seasonal pressure mean that exhaust residue and road-salt spray accumulate quickly on airframes during winter operations. Rinseless cleaning avoids the complications of frozen wash water and icy aprons, and the handler expects advance notice during peak weeks when the GAC apron is crowded. Non-commercial curfew rules mean that if a turnaround is planned for early morning, the aircraft must arrive before 22:00 the previous evening to allow time for the cleaning crew to finish before the stand is needed again at first light.

How does the handler coordinate third-party exterior work at Salzburg?

The handling agent present at the airport manages apron access, GPU and airside escort for the detailing crew. Terso arrives with its own rinseless products, microfibre cloths, degreasing agents and ladders; the handler provides the stand assignment, confirms the aircraft will remain on chocks and ensures that pitot covers and static-port protection are in place before work begins. If the tech log notes any open deferred items near access panels or the belly, the crew is briefed before anyone touches those areas.

Coordination begins as soon as the flight is in the system. The handling agent needs the registration, MTOW, arrival and departure times, and whether the aircraft will cold-soak overnight or turn within a few hours. That information determines whether the dry wash fits between legs or must wait until after the last sector of the day. The handler also confirms that no maintenance or fuelling will overlap with the cleaning window, because a fuel truck alongside means the detailing crew must pause and clear the area until the operation is complete.

Airside-pass requirements are straightforward: Terso holds its own escort authority at major European airports, but at smaller fields the handler provides the escort if local rules require it. The GAC apron is compact, so the handler's ramp supervisor usually walks the crew to the stand and returns to sign off when the work is finished and all equipment has been removed from the apron.

Why choose rinseless over a traditional wash at this airport?

Salzburg has no dedicated business-aviation wash bay, and in winter a traditional hose-and-bucket wash on an open apron risks frozen runoff and ice formation under the aircraft. Rinseless products eliminate that risk: the detailing crew applies the solution with damp microfibre cloths, lifts the soil and hydraulic film, then buffs the surface dry in a single pass. No water pools on the stand, no drainage system is needed, and the process works in temperatures well below freezing as long as the crew's hands and cloths remain workable.

Bug strikes and exhaust soot are the primary targets. Leading edges collect insect residue during climb-out over the Inn valley and surrounding alpine terrain, while nacelle interiors and the belly accumulate carbon deposits and hydraulic mist from normal operations. A dry wash removes all of it without the mess of a wet decon, and because the aircraft never needs to be towed to a wash pad, turnaround time is shorter and the handler's workload is lighter.

Operators running regular schedules into Salzburg—particularly those serving ski-season charters or corporate shuttles—often put the aircraft on a two-week or four-week dry-wash cycle to keep the exterior presentable without the logistical burden of a full wash and wax. The service fits neatly into overnight stops or mid-morning turnarounds when the aircraft will sit for three hours or more.

What does the exterior dry wash process include?

The crew begins at the nose and works aft, cleaning the fuselage, wings, empennage and nacelles in sections. Bug residue on the leading edges and windscreen receives focused attention: the rinseless product softens the protein deposits, and a second pass with a clean cloth lifts them without scratching the paint or the glass. Exhaust staining around the APU outlet and nacelle trailing edges is treated with a stronger degreasing agent, applied and wiped in the same manner.

Belly and landing-gear cleaning is part of the standard scope. The crew degreases the gear bays, struts and wheels, removing hydraulic film, brake dust and road grime tracked up from the apron. Gear doors and the lower fuselage are wiped down to eliminate the oily film that collects during taxi and take-off. Exterior windows, navigation lights, beacon housings and the pitot probe (external surfaces only, never the sensing ports) are cleaned and polished.

Brightwork receives a light touch-up: leading-edge strips, nacelle lips and any polished aluminium accents are buffed to remove oxidation and restore a uniform finish. The process does not include a full polish or ceramic coating—those are separate services—but it does leave the metal bright enough that the aircraft looks sharp on the ramp. Duration runs from three hours for a super-midsize jet to eight hours for an ultra-long-range airframe, depending on the level of soiling and the size of the tail.

How do recurring and one-off schedules differ at Salzburg?

Aircraft based at Salzburg or operating a regular shuttle into the airport are usually placed on a recurring dry-wash programme, with the service performed every two to four weeks depending on utilisation and the owner's standards. The handler and the detailing crew establish a standing slot—often a weekday morning or a Sunday afternoon when the apron is quieter—and the work happens automatically unless the flight schedule changes. The chief pilot or flight-department manager receives a brief report and photos after each visit, and the tech log is endorsed if the operator requires it.

One-off requests come from transient aircraft: a charter operator inbound for a ski-season trip, a corporate jet arriving dirty after a long positioning leg, or a flight department that wants the aircraft cleaned before the principal boards for the return sector. These are coordinated on shorter notice, sometimes twenty-four to forty-eight hours ahead, and the handler confirms whether the turnaround window is long enough to complete the work. If the aircraft is scheduled to depart within three hours of landing, the dry wash may not fit unless it is a smaller jet and the soiling is light.

Both models rely on the same process and products, but the recurring programme offers predictability: the handler knows the aircraft is coming, the stand is pre-assigned, and the detailing crew arrives with the correct equipment and enough staff to meet the timeline. One-off jobs require more communication and occasionally involve trade-offs—cleaning only the fuselage and wings, for example, if time does not allow a full belly decon.

What operational timing works best for dry wash between legs?

A typical midsize jet requires four to five hours for a complete exterior dry wash, so the ideal window is a daytime turnaround with at least six hours on the ground, allowing time for the handler to refuel and complete ramp services before the detailing crew begins. If the aircraft lands at 10:00 and departs at 17:00, the wash starts around 11:30 once fuelling and any catering or lavatory service is finished, and the crew finishes by 16:00 with an hour to spare.

Overnight stops offer more flexibility. The aircraft arrives in the evening, the dry wash begins the following morning after the handler's ramp supervisor confirms the stand is clear, and the work is complete by early afternoon. This schedule suits larger aircraft that need the full eight hours and cannot fit the service into a short turnaround. It also avoids the risk of delaying a departure if the cleaning takes longer than expected or if the crew discovers heavier soiling that requires extra passes.

Early-morning departures require careful planning because of Salzburg's non-commercial curfew. If the aircraft must depart at 07:30, it needs to arrive the previous evening before 22:00 to allow the detailing crew to work through the night or start at first light. The handler coordinates GPU availability and apron lighting, and the crew ensures that all equipment is removed from the stand and the aircraft is ready for pre-flight inspection by the time the flight crew arrives. Turnarounds tighter than three hours are generally not suitable for a full dry wash unless the operator accepts a reduced scope—fuselage and wings only, with the belly and gear deferred to the next stop.
