Exterior Dry Wash at Milan Linate (LIML)

Why choose a dry wash at Milan Linate instead of a wet wash?

Linate Prime operates on a shared apron with scheduled movements, and access to a wash bay is rarely practical during a quick turn. A dry wash uses aviation-approved waterless products applied by hand, leaving no runoff and requiring only a GPU and airside escort. The handler stays informed through a pre-arrival briefing, and we coordinate stand time to the minute.

Bug strikes accumulate quickly on the leading edges and windscreen in the warmer months, while exhaust soot clings to the belly and nacelles year-round. Left for more than a fortnight, both become baked onto the paint. A dry wash lifts them without introducing water near static ports, pitot probes or avionics bays. Brightwork on wing leading edges receives a light polish to remove oxidation, and exterior windows are cleaned inside the same visit.

The process works equally well in winter. We avoid washing when the airframe is cold-soaked below five degrees Celsius, but a dry wash can proceed on a stand in any season as long as the aircraft has had time to warm through after arrival.

What changes at Milan Linate for this service?

Milan Linate sits at 353 feet elevation, seven kilometres from the city centre, and operates around the clock with no curfew. The airport is slot-coordinated, so every arrival and departure window matters. Runway 17/35 measures 2,442 metres; the designation changed with AIRAC A10/23 in November 2023, and some charts still show the old 18/36 identifiers. All business aviation moves through Milano Linate Prime, the dedicated terminal run by SEA Prime, making it Italy's busiest private-aviation gateway.

Five handling agents operate at the airport: SEA Prime, Signature Aviation, Universal Aviation Italy, Sky Services and AviaVIP. We liaise with whichever agent is on your handling order to confirm stand allocation, GPU availability and escort timing. Slot pressure means a dry wash is often scheduled overnight or during a longer daytime stop; we adapt to your PPR and the handler's apron-movement plan. The absence of a curfew gives flexibility for late arrivals, though winter daylight ends early and exterior work benefits from stand lighting after 16:00 local in December and January.

How does the photo-report process work after a dry wash?

Every exterior dry wash concludes with a digital photo report: close-ups of the cheat line, belly, nacelles, winglets and leading edges, plus wide shots of both sides and the tail. Images are date-stamped, labelled by airframe station and uploaded as a PDF to your nominated email or tech-log portal within two hours of sign-off. Chief pilots use the report to track paint condition between heavier details, and charter operators attach it to pre-flight documentation when the client asks for proof of cleanliness.

We also note any paint chips, hydraulic weeps or loose fasteners in a remarks field at the end of the report. These observations do not replace a formal inspection, but they give the flight crew a heads-up before the next leg. If you maintain a recurring schedule—say, a dry wash every three weeks—the photo archive builds a visual maintenance history that highlights exactly when a scuff or a stain first appeared.

What do handlers at Linate expect from a third-party detailing crew?

Handling agents at Linate Prime require an airside pass or continuous escort, proof of liability insurance and a written work order that names the aircraft registration and the scope. We hold a permanent airside pass for LIML, carry ten-million-euro cover and send the handler a one-page brief forty-eight hours before the slot. The brief lists arrival time, stand preference, power requirements and expected finish time so the agent can plan GPU placement and any apron movements.

On the day, we check in at the handler's operations desk, collect the escort if required and move to the stand as soon as the aircraft is chocked and the engines are cool. Pitot covers and static-port bungs stay in place throughout; we work around them and never introduce moisture near a probe. All waste—used microfibre cloths and empty product bottles—leaves the apron in a sealed bag. The handler appreciates a fifteen-minute warning before we finish so ground staff can prepare for the next departure or tow, and we update the agent immediately if weather or a technical delay pushes the completion past the agreed window.

How do you time a dry wash between legs at a busy city hub?

Linate's slot structure and proximity to Milan's business district mean many aircraft turn in three to five hours. A super-midsize cabin takes four hours to dry-wash; an ultra-long-range airframe stretches to seven or eight. If the inbound slot lands at 08:00 and the outbound departs at 14:00, we start as soon as the engines spool down and the GPU is connected, finishing with an hour to spare for catering, fuelling and the walk-around.

When the turn is tighter, we split the clean across two visits: upper surfaces and one side on arrival, the opposite side and belly during the next overnight stop. That approach works well for shuttle operations or when the aircraft overnights midweek and departs early the following morning. The handler's apron-movement schedule drives everything; if a stand change is planned, we either pause and resume on the new spot or reschedule to a day when the aircraft remains static for six hours or more.

What does Milan's climate do to paint and exterior surfaces?

Milan's summers bring high insect activity and afternoon temperatures that bake bug residue onto leading edges and windscreens within days. Exhaust soot from short hops across Europe settles on the belly and around the APU outlet, mixing with hydraulic mist to form a sticky film that attracts dust on the next approach. A dry wash every two to four weeks prevents both from etching the clear coat.

Winter fog and light rain leave water spots on the fuselage if the aircraft sits on the ramp for more than a day, and de-icing fluid—Type I or Type IV—can streak the belly and gear doors if not rinsed or wiped soon after application. We remove dried glycol residue as part of the belly degreasing step, restoring the hydrophobic finish so the next rain sheets off cleanly. Brightwork on nacelle lips and wing leading edges oxidises faster in the damp months; a light single-stage polish during each dry wash keeps the aluminium bright without a full compound-and-wax cycle.
