Exterior Dry Wash at Vienna (LOWW)

Why choose rinseless detailing at Vienna?

Vienna sits 18 km east of the city centre at 600 ft elevation, where continental winters and warm summers deposit a visible film: road salt tracked onto aprons by ground vehicles, pollen from the Danube basin in spring, and a fine Alpine dust that clings to leading edges and belly panels after every descent through the inversion layer. Dry wash removes all of it without the logistical overhead of a wash bay—no towing, no water-truck scheduling, no wait for a stand with drainage.

The process uses aviation-approved waterless emulsions that encapsulate contaminants and leave a light hydrophobic finish. We clean the entire exterior envelope: fuselage from nose to tail, wing upper and lower surfaces, empennage, nacelles, exterior windows, lights, and a light polish on aluminium leading edges where bug strike and oxidation are heaviest. Belly and gear-bay degreasing lifts hydraulic mist and carbon residue without solvents that attack seals. The result is a presentable aircraft in three to eight hours, depending on size and soil load, with no downtime beyond the turnaround you already planned.

What changes at Vienna?

LOWW operates H24 with no formal curfew, but night movements between 23:30 and 05:30 local are capped under the mediation agreement, and runway-direction availability is restricted from 21:00 to 06:55. The airport has two runways—16/34 at 3,600 metres and 11/29 at 3,500 metres—and is Level 3 fully coordinated: IFR GA and business-aviation flights require airport slots requested between twenty-eight days and four hours before the operation, submitted through your handling agent. VFR flights are exempt from the slot rule but must follow the PPR procedure in AIP Austria.

Three handling agents are present at the airport: Vienna Airport FBO (Vienna Aircraft Handling, airport-owned), Jet Aviation Vienna, and Magnum FBO. All operate from the General Aviation Terminal or General Aviation Center on the west side of the field, about three kilometres from the passenger terminals. Vienna Aircraft Handling is available around the clock with a twenty-four-hour hotline and offers hangarage; Jet Aviation runs a twenty-four-hour FBO with office hours from 07:00 to 22:00 and lists interior and exterior aircraft cleaning among its own services. That means detailing at Vienna is possible any hour, but you may find yourself competing with in-house FBO cleaning for stand time—early coordination with the handler and the tech log is essential.

At 600 ft elevation, cold-soaking is rarely an issue even in January, but winter apron temperatures do slow the curing of waterless products. We adjust dwell time and work sequence to keep the aircraft on schedule.

Recurring base maintenance versus one-off turnarounds

Vienna is a natural base for Central European flight departments: short positioning to Salzburg, Munich, Zürich, and Prague, excellent handler infrastructure, and no night curfew if you can secure a slot inside the mediation cap. If your aircraft overnights here twice a month or more, a standing dry-wash schedule—every two to four weeks—keeps the paint clean and prevents the build-up of hydraulic film that becomes baked-on carbon after a summer on the ramp.

We book recurring work as a single standing order with the handler, so there's no repeated PPR paperwork and no surprise stand charges. The aircraft is cleaned during its scheduled overnight or during a planned maintenance window, and the tech log is closed before the next departure. For fleets running multiple tails through Vienna, we can stagger the calendar so that one aircraft is always fresh for client-facing legs.

One-off turnarounds are just as common: an unscheduled diversion, a last-minute charter pickup, or a cabin handover that requires an exterior to match the new interior. We mobilise within four hours if the slot and stand are confirmed, and we work around GPU changes, catering, and fuel trucks. The only constraint is airside-pass coordination with the handler—Vienna's security office requires forty-eight hours' notice for temporary escorts, so if you know the diversion is likely, a heads-up to the FBO smooths the process.

What does the service leave clean?

Every panel the air touches. We start at the nose—radome, windscreens, forward fuselage—and work aft in overlapping sections, lifting bug residue from the leading edges, exhaust soot from the tail cone, and the grey hydraulic mist that collects in the gear bays and belly. Wings are cleaned upper and lower surface, nacelles from intake to pylon, and the empennage including the ventral fin if fitted. Exterior windows and position lights are polished, and brightwork—aluminium leading edges, nacelle lips—receives a light single-stage polish to remove oxidation without cutting through anodising.

The belly and gear bays get dedicated attention. We degrease the keel, flap tracks, and main-gear doors with a pH-neutral cleaner that breaks down hydraulic film and carbon without attacking seals, then wipe down the gear struts and brake assemblies. It's not a pre-sale cosmetic polish—it's functional cleaning that prevents corrosion and makes the next pre-flight inspection easier.

We do not touch pitot probes, static ports, or any panel marked 'no cleaning' in the maintenance manual. Avionics bays and sensor windows are avoided entirely. If the cheat line or tail logo needs repainting, we note it in the handover but do not attempt touch-up—that's a paint shop with OEM colour-match.

How does timing work between legs?

Dry wash fits into the same window as refuelling and cabin cleaning, provided the handler knows the sequence. A super-midsize jet takes three to four hours; an ultra-long-range airframe with a high belly and complex winglets takes six to eight. We start as soon as the aircraft is on chocks and the GPU is connected, working around catering and lav service. If the turnaround is tight—two hours between legs—we prioritise the fuselage, wings, and exterior windows, then return to the belly and gear bays during the next overnight.

Night work is possible under Vienna's H24 operating hours, but remember the slot caps: between 23:30 and 05:30 local, the airport is under the mediation agreement's movement limit, and from 21:00 to 06:55 runway-direction availability is restricted. If your departure slot is inside that window, we schedule the wash to finish at least ninety minutes before pushback, leaving margin for a final walk-around and tech-log sign-off. Cold winter aprons slow the curing of waterless emulsions, so we add thirty minutes to the timeline between November and February.

What about winter operations and de-icing?

A clean exterior is not just cosmetic in winter—it's part of the holdover equation. Residual dirt, hydraulic film, and insect debris all reduce the effectiveness of Type I and Type IV anti-icing fluids, shortening the holdover time and forcing a second application if the slot is delayed. We coordinate with the handler so that dry wash is completed before the aircraft enters the de-icing pad, giving the fluid a clean surface to bond to.

After de-icing, we do not touch the aircraft. Pitot covers and static-port plugs are the flight crew's responsibility, and we stay clear of any surface that has been treated. If you return to Vienna the next day and the wings are still coated in dried Type IV residue, a post-flight rinseless wash will lift it without damage, but that's a separate service call—never performed immediately after fluid application.
