Exterior Dry Wash at Frankfurt Airport (EDDF)

Why choose a dry wash at Frankfurt Airport?

Slot coordination and a night-flight ban frame every turnaround at EDDF. You cannot always afford the two-hour block a traditional wash bay requires, nor can you guarantee that a bay will be available when your aircraft lands. A dry wash happens where the aircraft parks—on the GAT ramp or at the handler's stand—using only hand-applied product, microfibre and elbow grease. No hoses, no drainage, no repositioning.

The method works because modern waterless formulations emulsify contaminants on contact, letting you wipe away soot, bug residue and light oils without scratching gelcoat or paint. Leading edges see extra attention: a soft brush lifts compacted insect protein, and a separate pass removes any haze. Belly panels and gear bays are degreased with a heavier concentrate, then wiped clean. The entire exterior—including nacelle inlets, antennas and static ports—is treated in one continuous sequence, so the aircraft rolls to its next leg looking sharp and the flight department avoids the paperwork of an off-airport wash facility.

What changes at Frankfurt Airport?

Frankfurt Airport sits at 364 feet elevation, twelve kilometres south-west of the city centre, and operates under a court-imposed night-flight ban from 23:00 to 05:00 local. The shoulder hours—22:00 to 23:00 and 05:00 to 06:00—are capped at an average of 133 movements per night across the year, which means most business-aviation departures cluster between mid-morning and early evening. Four runways handle the traffic: 07C/25C and 07R/25L each stretch 4 000 metres, 18 (departures only) runs 4 000 metres, and 07L/25R measures 2 800 metres. Every movement, general aviation included, requires an allocated slot; EDDF is a Level 3 fully coordinated airport.

Three handling agents operate from the General Aviation Terminal in Building 514 on the south side: Fraport Executive Aviation, Business Aviation Centre Frankfurt (Kurz Aviation Service) and FAS Frankfurt Aviation Service. The GAT maintains its own customs and passenger-inspection facility and runs terminal services from 06:00 to 22:00, though FBO desks and prior-permission-required coordination are available around the clock. For a detailing crew, that means airside-pass escort from the handler, a ramp slot that does not conflict with pushback or towing, and a weather watch: central Germany's mix of winter road salt, summer thunderstorm cells and year-round industrial haze all accelerate paint oxidation and leave a visible film on windscreens and cheat lines.

How does timing work between legs at Frankfurt?

A three-hour turnaround is typical for a super-midsize jet: passengers disembark, the aircraft is refuelled and catered, the tech log is signed, and the next departure slot approaches. If you want the exterior cleaned, the window is tighter still. We coordinate directly with your handler to confirm stand assignment, GPU hookup and any planned maintenance access. Once the aircraft is chocked and the APU or ground power is live, the dry-wash crew begins at the nose and works aft in overlapping passes.

On a mid-cabin jet—Challenger 350, Praetor 600, Citation Longitude—the process takes three to four hours with two technicians. An ultra-long-range airframe such as a Global 7500 or Gulfstream G650 will stretch to six or seven hours if the belly has not been touched in months. We build the schedule around your slot: if you land at 10:00 and depart at 16:00, we start as soon as the handler clears us onto the apron and finish with time for a walk-around inspection. If the gap is shorter, we prioritise the fuselage sides, wings and tail—the surfaces passengers and ramp personnel see—and defer the belly to the next station. The goal is always to hand back an aircraft that is clean, dry and ready for pushback without delaying your PPR or customs window.

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

German airport security is methodical. Every technician carries a government-issued airside pass or works under continuous escort by the handler. We notify the FBO forty-eight hours before arrival, supply passport copies and vehicle registration, and confirm which stand the aircraft will occupy. On the day, we check in at the GAT desk, collect the escort if required, and drive airside in a van stocked with product, ladders and lighting.

The handler wants three things: no interference with refuelling, no contact with avionics or pitot-static systems, and no spills on the apron. We stage our kit downwind of the aircraft, keep all containers sealed until use, and lay absorbent mats under the belly if we are degreasing gear bays. If line maintenance is scheduled—an engine-oil service, a hydraulic-reservoir check—we pause our work, move the ladders clear, and resume when the engineer signs off. Communication is constant: the handler's ramp supervisor has our mobile number, and we confirm every move—engine-inlet access, tail-stand placement, departure countdown—before it happens. That level of coordination is what keeps Terso on the approved-vendor list at EDDF and every other major European hub.

Which contaminants does a dry wash remove, and which does it leave behind?

Waterless chemistry excels at organic films: bug protein, exhaust carbon, lavatory-service splash, light hydraulic mist and the oily haze that settles on fuselage sides near busy taxiways. The surfactants in the product encapsulate each particle, lifting it away from the paint so a clean microfibre can carry it off. You will also see an immediate improvement on windows, nav lights and the unpainted strips along door seals.

What a dry wash will not do is remove heavy oxidation, deep water spots or the white calcium bloom that appears after weeks of rain and hard-water rinses. If the cheat line has turned chalky or the belly shows layered crud from a winter of de-icing fluid, you need a wet wash or a single-stage polish. Similarly, if leading edges are pitted from hail or sand, a dry wash will clean the surface but not restore the profile; that requires wet sanding and compound. We assess the aircraft on arrival and tell you honestly whether a waterless clean will meet your standard or whether you should plan a more invasive detail at the home base. Most operators find that a dry wash every two to four weeks, supplemented by a wet wash twice a year, keeps the exterior in presenting condition without surrendering half a day to a wash bay.

How do winter operations and de-icing affect the schedule?

Frankfurt's winter begins in earnest around late November and runs through February, bringing freezing fog, occasional snow and regular applications of Type I and Type IV fluid. When the airframe is cold-soaked—wings and belly still below zero after an early-morning arrival—you cannot apply waterless product; the chemistry will not emulsify, and you risk streaking or residue. We wait for the surface temperature to climb above five degrees Celsius, either by letting the aircraft sit in weak sun or by requesting a heated hangar slot if the handler has space.

De-icing fluid complicates the picture. Type I glycol rinses off easily, but Type IV—the thickened polymer that clings to the upper wing—leaves a tacky film on fuselage sides and tail surfaces if overspray drifts during application. A dry wash will remove fresh overspray, but if the fluid has baked on under cabin heat or sat for days, a wet decon is the only answer. We carry a sample of the aircraft's paint code and test a small patch—usually low on the belly or inside a gear door—before committing to a full exterior pass. If the test shows streaking, we stop, document the condition, and recommend a proper wash bay at the next maintenance base. Transparency here protects both the paint and the operator's schedule.
