Exterior Dry Wash at Cuneo Levaldigi (LIMZ)

Why choose a dry wash instead of a wet rinse at Cuneo?

Water access on the Levaldigi apron is limited, and the airport's environmental rules require containment of any runoff from traditional pressure washing. A dry wash eliminates both problems: aviation-grade waterless emulsions encapsulate dirt and are wiped away with microfibre, leaving no standing water and no need for bunded drainage. The chemistry is designed to lift bug protein, kerosene residue and hydraulic mist without scratching gelcoat or polished aluminium, so the process is safe for composite leading edges, nacelle inlets and painted surfaces alike.

Operationally, a dry wash is faster to set up—no hoses, no GPU-fed heating, no wait for a wash crew to rig containment mats—which matters when your slot at the next field is two hours away. We bring our own product, tools and lighting; the handler provides only apron access and, if the work runs past daylight, airside escort. For fleets running tight European schedules, the dry-wash method turns a six-hour wet detail into a four-hour ramp clean, and you depart with a fuselage that photographs well and sheds rain cleanly until the next stop.

What does the exterior dry-wash process include?

We start at the nose and work aft in panels: fuselage crown and sides, cheat line, belly, all control surfaces, winglets, nacelles and the empennage. Bug strikes on the leading edges and radome are treated with a separate bug-release gel that sits for a few minutes before being wiped clean; exhaust soot around the tailpipe and APU outlet receives a degreasing emulsion. The belly and main-gear bays are degreased to remove hydraulic film, brake dust and tyre rubber; nose-gear doors and strut are wiped down but not polished unless you add a single-stage correction.

Exterior windows—cockpit, cabin, entry door—are cleaned with an ammonia-free glass product that leaves no streaking on heated panes. Position lights, landing lights and the beacon lenses are wiped clear of bug residue. Brightwork—polished leading-edge strips, nacelle lips, door handles—receives a light touch-up with a non-abrasive metal polish, enough to remove oxidation haze but not a full correction. We mask or avoid pitot probes, static ports, AOA vanes and any no-touch avionics fairings; if you have a paint-protection film on the leading edges, we note it in the log and adjust chemistry accordingly.

Duration depends on size: a super-midsize airframe takes three to four hours; an ultra-long-range jet with a tall T-tail and complex belly fairings can run to eight. We deliver a dated photo set—nose, both profiles, tail, close-ups of any paint chips or corrosion spots—and a signed tech-log entry before you board.

What changes at Cuneo Levaldigi that affects the wash?

Cuneo Levaldigi sits at 1,267 feet on a plateau at the foot of the Maritime Alps, twenty kilometres north-west of Cuneo city centre. The single runway—03/21, 2,100 metres, ILS-equipped—handles large-cabin business jets without MTOW restrictions, but the airport operates strictly between 07:00 and 21:00 local (05:00–19:00 UTC in summer, 06:00–20:00 UTC in winter), with ATS and handling available beyond those hours only by prior arrangement. That daytime-only window means all ramp work, including a dry wash, must be scheduled to finish before the curfew or you will need to request an extension through Italy FBO well in advance.

There is no separate general-aviation terminal; business jets park on the main apron adjacent to the passenger building, and the handler—Delta Aerotaxi—coordinates all ground services from the same facility. Customs is on site and follows airport hours, so non-Schengen arrivals can clear at Cuneo without diverting to Torino or Milano. The elevation and alpine proximity bring sharp temperature swings between day and night, especially in spring and autumn: a cold-soaked airframe that arrives at dawn will carry condensation on the belly and gear bays, which slows the first wipe-down until the metal warms. Conversely, summer afternoons on the plateau can push thirty degrees, so we start the wash early to avoid working gelcoat that is too hot to touch safely.

Winter operations are rare for business jets—Cuneo is a seasonal leisure airport with most traffic in summer—but when a jet does arrive between December and February, expect snow-contaminated bellies, de-icing-fluid residue on the wings and nacelles, and salt spray if you have flown low over the Ligurian coast. A dry wash will remove Type I glycol film and road-salt haze, but if the airframe has been through multiple de-icing cycles without a rinse, we recommend a single wet decon at a larger base before reverting to waterless maintenance.

How do we coordinate a dry wash with the handler and your turnaround?

Timing is agreed as soon as you file the flight plan or, for positioning legs, when the previous sector's block-off is confirmed. We ask for aircraft type, registration, estimated chocks-on time, and the length of the ground stop; if you are turning in under four hours, we will stage the team on the apron before you land so the wash begins as soon as the cabin door closes and catering is clear. If the stop is overnight or longer, we schedule the wash to finish two hours before your next departure, leaving a buffer for any paint touch-ups or a quick cabin vacuum if the pilots request it.

The handler—Italy FBO—expects a formal work order or email confirmation from the chief pilot, flight ops or the charter broker, naming Terso as the third-party service provider and listing the scope (exterior dry wash, duration, any add-ons). We supply our own airside passes for the Cuneo airport authority, but if we arrive outside normal hours under an extension, the handler will provide escort. The aircraft does not need to be repositioned; we work around GPU leads, air-conditioning hoses and tow-bar if they are still attached, though it is easier—and faster—if the ramp is clear.

Photo documentation goes to the captain or the flight-department manager by email or WhatsApp within an hour of finish; the tech-log sticker with date, service description and technician signature is placed in the book before you pre-flight. If the handler invoices all ground services on one statement, we can bill through them; if you prefer a separate invoice, we send it directly to your accounts team with the same tail number and date reference.

What does Piedmont weather do to the paint between washes?

The climate at Levaldigi is continental with alpine influence: warm, dry summers and cold, occasionally snowy winters, with the heaviest rainfall in spring and autumn. Summer operations mean long days of ultraviolet exposure on the apron, which accelerates oxidation of single-stage paint and fades darker colours—navy, forest green, charcoal—faster than you will see at a coastal or northern European field. Bug strikes accumulate quickly in June and July when the plateau is warm and insects are active at altitude; if the airframe sits for more than forty-eight hours between flights, the protein hardens and requires a stronger bug-release gel, adding fifteen minutes to the wash.

Autumn and spring bring rain showers that leave hard-water spots on the fuselage if the aircraft is parked outdoors overnight; the local water is moderately hard, and spots will etch the clear coat if not removed within a week. A dry wash every two to four weeks prevents that etching and keeps the hydrophobic layer intact, so rainwater sheets off rather than beading and staining. Winter is the quietest season at Cuneo, but if you do operate in January or February, expect de-icing-fluid residue, road salt carried on the wind from the valley, and cold-soak condensation that traps dirt on the belly—all of which a waterless clean will remove, though a post-winter wet decon at your home base is still the best practice before the summer season begins.

When should a dry wash be part of the maintenance rhythm?

For aircraft in regular service—two or more legs per week—we recommend an exterior dry wash every two to four weeks, timed to coincide with a longer ground stop or a crew-rest overnight. The interval shortens if you are flying low-level legs (below FL250) in summer, when bug strikes and turbine exhaust accumulate faster, or if the jet is parked outside at multiple airports without hangar cover. A dry wash is not a substitute for an annual or six-monthly wet decon and polish, but it extends the life of that heavier detail by preventing dirt from bonding to the paint and brightwork from hazing over.

Operationally, the dry wash fits into any turnaround longer than four hours or any overnight stop; it does not require the aircraft to be hangared, cold, or disconnected from ground power, so it can run in parallel with cabin cleaning, catering or a minor tech inspection. The result is a presentable airframe for client flights, charter legs or pre-purchase inspections, and a smoother surface that improves airflow and, marginally, fuel efficiency. If you are operating into Cuneo as part of a Mediterranean or alpine tour—Cannes, Nice, Geneva, Lugano—a mid-tour dry wash at Levaldigi keeps the exterior sharp without the cost or delay of repositioning to a wash bay at a larger hub.
