Exterior Dry Wash at Adolfo Suárez Madrid–Barajas Airport (LEMD)

Why choose a dry wash instead of a traditional water wash at Madrid?

Water restrictions, ramp logistics and turnaround pressure make waterless cleaning the practical choice at a high-density coordinated airport. A traditional wash bay requires towing, queue time, wastewater capture and often a twenty-four-hour booking window; dry wash happens at your stand or inside the FBO apron, starts as soon as the aircraft cools and the GPU connects, and leaves no puddles for the handler to manage. Rinseless chemistry has matured: the surfactants encapsulate contaminant particles and are wiped away with microfibre, so you get the same clean surface without hoses, without runoff pH issues, and without waiting for a wash pad slot.

For fleets with a Madrid rotation every ten to fourteen days, dry wash becomes the interim service between deeper details. You keep the fuselage and nacelles free of exhaust bloom, the belly degreased, and the windscreen clear, so the quarterly or biannual polish stays effective longer. Single owners on European tours use it the same way: a four-hour dry wash in Madrid between Ibiza and Paris keeps the aircraft presentable without losing half a day to ground time.

What changes at Adolfo Suárez Madrid–Barajas Airport that affect the cleaning schedule?

Madrid sits at 1,998 feet elevation in a continental Mediterranean climate: hot, dry summers with intense UV, and cold winters where overnight temperatures regularly drop below freezing. Summer heat bakes exhaust residue and bug protein onto the nacelle cheeks and wing leading edges; if left more than two weeks, the film cross-links with the paint and needs a polish rather than a wash to remove. Winter brings road-salt spray from the apron tugs and belt loaders, plus the alkaline residue of Type I and Type IV de-icing fluid, all of which should be cleaned within seventy-two hours to prevent brightwork staining.

The airport operates H24 with no curfew, and four runways—the longest is 18R/36L at 4,179 metres—handle everything from regional jets to A380 positioning flights. Slot coordination applies equally to business aviation: you file for a slot from twelve hours local time the working day before, and any delay cascades. If your dry wash is scheduled for a six-hour window and ground time stretches, we work with the handler to pause and resume, or to finish the belly and gear bays on the next rotation if the slot becomes tight. Five handling agents operate from the Terminal de Aviación Ejecutiva, and all are accustomed to third-party cleaning crews working airside under escort with the appropriate airport pass.

How does the dry-wash process work on a super-midsize or larger airframe?

We begin with the nacelles and wing leading edges while the engines are still warm but safe to approach—exhaust soot lifts more easily before it fully cools and bonds. The fuselage, empennage and winglets follow, each panel wiped in overlapping passes with a pH-neutral rinseless solution and fresh microfibre towels; every three square metres we rotate to a clean cloth so we are removing contamination, not redistributing it. Exterior windows, lights and the windscreen are treated separately with an ammonia-free glass product that will not haze the anti-reflective coatings.

The belly and gear bays are degreased with a biodegradable solvent applied by hand-pump sprayer, then wiped down; we do not pressure-wash, so there is no risk of forcing water past seals or into static ports. Leading-edge brightwork—the nickel or stainless-steel strips on wing and tail—receives a light polish if oxidation or fluid staining is present. We finish with a walk-around to check panel gaps, door seals and the cheat line for any residue the first pass missed. On an ultra-long-range airframe the elapsed time is seven to eight hours with a two-person crew; a super-midsize is closer to four.

What do handlers at the Terminal de Aviación Ejecutiva expect from a third-party cleaning crew?

Every FBO and handler at Madrid requires proof of insurance, an airside escort if your crew does not hold a permanent LEMD pass, and a written work order or tech-log entry so ground staff know who is responsible for the aircraft during the service. We arrive with our own equipment, our own consumables, and our own waste bags; nothing is left on the ramp, and no wastewater enters the apron drains. If the aircraft is on a stand shared with fuelling or catering, we coordinate the sequence with the handler's ramp supervisor so hoses and belt loaders are not crossing our work area.

Handlers also expect clear communication about timing. If your slot is tight and the dry wash will run past the fuelling window, we tell the ramp coordinator at the start so they can adjust the GPU and tug schedule. If weather moves in—summer thunderstorms are brief but intense—we pause, cover the open panels, and resume when the apron is dry. The goal is to make the handler's life easier, not harder: we are an extension of your flight-department process, not a variable they have to manage.

How often should a dry wash be scheduled for an aircraft operating through Madrid regularly?

Every two to four weeks is the standard interval for a business jet in regular service, but the right frequency depends on your mission profile and your quality threshold. An aircraft flying Madrid–London–Geneva–Madrid every week will pick up enough exhaust soot, bug strike and apron dust that a monthly dry wash keeps the exterior acceptable between quarterly polishes. A charter operator running Ibiza shuttles all summer may need it every ten days because the coastal salt load and the insect density are both higher.

If you are basing the aircraft at Madrid for a seasonal contract or an extended owner stay, we build a recurring schedule with the handler: every second Thursday at 08:00, for example, with the dry wash complete before the afternoon departure. The predictability lets your flight department budget ground time, and it lets us pre-position supplies and crew so there is no delay. For one-off visits—a fuel stop, a crew change, a positioning leg—we work to your departure slot and scale the service: perhaps fuselage and nacelles only, skipping the belly, to fit a three-hour window.

What happens if the aircraft is AOG or if the schedule changes after we have confirmed the dry wash?

We hold the booking until you release us or until the new departure time is clear. If the aircraft goes AOG for a part or a tech issue and you need the dry wash deferred by six hours or two days, there is no penalty—we adjust the crew roster and notify the handler. If the schedule change is substantial and the dry wash no longer fits the maintenance window, we cancel and re-book for the next rotation. The only constraint is crew availability: if you call the morning of and ask us to move a six-hour service from afternoon to immediate, we will do it if the team is free, but we cannot always guarantee same-day flexibility at a coordinated airport where every other operator is managing the same slot pressures.

For recurring clients, we keep a rolling seventy-two-hour forecast of your fleet movements and pre-clear airside access, so last-minute changes are easier to absorb. Single visits require more lead time—ideally forty-eight hours—so we can arrange the escort, confirm the stand assignment with the handler, and have the consumables on site.
