WHAT CHANGES THE SCHEDULE
Bug season: insect residue is acidic and bakes onto leading edges, windshields, and inlets. In summer, a quick de-bug after every few flights keeps it from staining.
Winter operations: de-icing and anti-icing fluids leave a residue that attracts dirt. Washing after a de-icing event, and at the end of the season, keeps it from building up.
Outdoor parking: aircraft that live on the ramp collect dust, pollen, and bird droppings much faster than hangared aircraft.
Utilization: an aircraft flying several legs a week needs more frequent attention than one flown a few times a month.
WET WASH OR DRY WASH?
A wet wash uses water and aviation-safe soap. It's the most thorough option and the right choice for heavy soiling, landing gear, and belly panels, but many ramps and FBOs restrict water use.
A dry (waterless) wash uses products that lift and encapsulate dirt so it can be wiped off without scratching. It can be done almost anywhere, including inside a hangar or on a busy ramp, and is ideal for routine maintenance washes between deeper cleanings.
PROTECT THE FINISH BETWEEN WASHES
A wax or ceramic coating makes every wash faster and safer for the paint. Contaminants release more easily, so less scrubbing is needed. Ceramic coatings in particular can stretch the time between deep washes.
Always follow your aircraft manufacturer's maintenance manual for approved cleaning products and procedures.
