Exterior Dry Wash at Frankfurt-Egelsbach (EDFE)

What changes at Frankfurt-Egelsbach?

Egelsbach sits at 385 feet elevation with a single 1 400-metre runway (08/26), handling over 80 000 movements a year as the primary general-aviation reliever for Frankfurt Airport, about ten kilometres to the north-west. There are no scheduled airline services; the whole field is dedicated to business and regional GA traffic. Operating hours run daily from 08:00 to 21:00 local, but that end-point is always capped at the end of civil evening twilight (ECET), whichever comes earlier—so in winter, the field closes well before nine in the evening. Any movement outside those hours, or at night, requires prior-permission-required (PPR) approval, and PPR is also mandatory for aircraft above 5.7 tonnes MTOM, for jets and turboprops in approach categories B or C, and for anyone requesting full-service handling.

For detailing work, that means we schedule dry washes entirely within daylight operating hours or arrange access directly with TRIWO, the airport operator. There is no runway coordination to worry about—Egelsbach is not slot-coordinated—but the PPR process and the twilight curfew shape our planning. If your aircraft will overnight on stand and you want a morning departure with a clean exterior, we either complete the wash the afternoon before or arrange early airside access by prior agreement. The single handling agent present at the airport is TRIWO Handling, which operates the terminal and offers full-service handling on PPR request; we coordinate our ramp time and GPU or towing requirements through them or directly with your flight crew if you are self-handling.

How does a waterless wash work on the ramp at a busy GA field?

We bring our own water supply, rinseless cleaning concentrate, microfibre applicators and finishing towels, so the process produces no standing runoff and needs no wash bay. The crew applies product in sections—typically one wing or half the fuselage at a time—then lifts dirt with clean microfibre before it can scratch, and buffs to a streak-free finish. Bug strikes on leading edges and nacelle inlets get pre-treated with a bug-release gel; belly panels and gear bays are degreased with a separate aviation-safe solvent that cuts through hydraulic mist and carbon buildup. Exterior windows and lenses are cleaned last, using a separate glass product and lint-free cloths.

At a field turning over eighty thousand movements a year, ramp space is at a premium and stands are rarely empty for long. We work around your turnaround schedule: if you have a two-hour slot between legs, we focus on the upper surfaces, cheat line and windows; if the aircraft will sit overnight, we complete the full exterior including belly and gear. The process is quieter and faster than a pressure wash, and because there is no overspray, we can work immediately adjacent to other aircraft or inside a busy apron without affecting neighbouring stands. TRIWO's operations office is staffed from 08:00 to 21:00 local and by arrangement, so any last-minute changes to stand allocation or GPU availability are communicated quickly.

What does the handler expect from a third-party detailing crew?

TRIWO, like most GA operators, expects third-party service providers to hold current airside passes or to be escorted at all times. We carry our own insurance and provide advance notice of our arrival, vehicle registration and crew names so that the handling desk can issue temporary access or arrange an escort from the terminal to the stand. If you have requested full-service handling through TRIWO, they will coordinate our ramp access as part of that package; if you are self-handling, we liaise directly with your captain or dispatcher to confirm stand number, GPU availability and any towing requirements.

The handler also expects us to leave the stand clean—no product pooling under the aircraft, no towels or packaging left behind—and to stay clear of static ports, pitot tubes and any no-touch avionics bays. We bring our own rubbish bags and remove all waste from the ramp at the end of the job. If the aircraft will be towed after the wash, we confirm with the handler that all gear pins are reinstalled and documented, and we note the stand condition in our own photo report so there is no ambiguity about pre-existing fluid stains or tyre marks. Egelsbach's high movement count means handlers are used to quick turnarounds and third-party crews; clear communication and tidy work keep everyone on schedule.

What does the climate around Frankfurt do to paint and brightwork?

Central Germany sees cold, damp winters and warm, humid summers, with frequent rain throughout the year and occasional snow from December through February. That mix keeps dirt in suspension: road spray, agricultural dust from the surrounding farmland, and pollen in spring all bond to wet paint and form a film that traps moisture against the clearcoat. Left unwashed, that film accelerates oxidation and dulling, especially on older paint systems without modern UV inhibitors.

Bug strikes are heaviest from May through September, when evening departures put insects in the flight path during their most active hours. Leading edges, nacelle lips and the windscreen arch collect the worst of it; if not removed within a few days, the acidic residue etches into the paint and requires polishing to restore gloss. Exhaust soot—particularly from APU cycles during ground ops—settles on the tail cone and aft fuselage, and in winter that soot mixes with road salt tracked onto the apron by ground vehicles, forming a corrosive paste in panel seams and around fasteners. A dry wash every two to four weeks lifts that contamination before it bonds permanently, and the hydrophobic finish we leave behind sheds water and delays the next buildup. Brightwork—spinner caps, nacelle rings, door handles—shows tarnish faster in damp air; we wipe those down with a separate metal polish during each wash to keep the contrast crisp.

How do access and airside logistics work at Egelsbach?

Egelsbach is a compact, single-runway field with all aircraft parking and the terminal concentrated in one area, so once we are airside the distances are short and the layout is straightforward. The challenge is timing: because the field closes at ECET or 21:00 local—whichever comes first—and because PPR is required for many aircraft types and all out-of-hours movements, we build our schedule around your approved slot and the available daylight. In midwinter that might mean a latest start time of 15:00 to finish before twilight; in midsummer we have until well after eight in the evening.

If your aircraft will overnight, we prefer to start the wash in late afternoon so we finish in daylight and the paint is dry before evening dew forms. If you are turning around during the day, we coordinate our arrival with your block-off time and work as quickly as the aircraft size allows—typically three hours for a super-midsize, up to eight for an ultra-long-range jet with a full belly degreasing. TRIWO's handling team can provide GPU if your APU is due for a rest, and they can tow the aircraft to a quieter stand if the active apron is too congested. We carry our own lighting for final inspections, but we avoid working after ECET unless the movement has prior approval and the handler is staffed to support it. The single terminal building houses the operations office, lounge and handling desk, so any last-minute coordination—stand changes, weather delays, tech-log queries—is handled face-to-face or by phone within minutes.

What documentation and photo reporting do you provide after the wash?

Every exterior dry wash includes a written report and a set of timestamped photographs, delivered by email within two hours of completion. The report lists the products used, the areas cleaned, any pre-existing damage or staining we observed, and the names of the crew who performed the work. The photos show the aircraft before we start, detail shots of leading edges and belly panels mid-clean, and the finished exterior from all four quadrants. If we find fluid leaks, missing fasteners, cracked lenses or paint chips, those are documented with close-up images and noted in the report so your maintenance team can add them to the tech log.

For flight departments running a fleet or charter operators tracking multiple aircraft through Egelsbach, that documentation provides a dated record of condition and cleaning intervals, which is useful for scheduling the next polish or planning a major decon. We also note the stand condition and any ground-equipment marks or tyre stains that were present before we began, so there is no confusion if the handler later finds a hydraulic drip or a scuff. The report and photos are stored in our own records for twelve months and can be re-sent on request if you need them for an audit or a pre-purchase inspection. If you prefer a different format—PDF summary, integration with your maintenance-tracking software, or a shared folder—we adapt the workflow to match your existing processes.
