WHY SOME AIRCRAFT ARE WASHED EVERY 15-30 DAYS

WHY WOULD AN AIRCRAFT NEED CLEANING THAT OFTEN?

For someone accustomed to automotive detailing, washing an aircraft every few weeks may sound excessive.

In aviation, however, cleaning frequency is not determined only by appearance.

Operating environment matters.

The FAA’s Corrosion Control for Aircraft guidance recommends a comprehensive corrosion-prevention program that includes periodic cleaning, inspection, lubrication, and preservation.

Its suggested intervals vary according to the severity of the operating environment:

Mild environment — 90 days
Moderate environment — 45 days
Severe environment — 15 days

The principle is important:

The more aggressive the environment, the shorter the interval between preventive care.

THE MILITARY TAKES SALT EXPOSURE EVEN FURTHER

U.S. Air Force Technical Order 1-1-691 provides an even clearer example of how seriously aviation treats coastal exposure.

Under the Air Force corrosion-control program, aircraft stationed within 1.25 miles of salt water are considered to be operating in a severe environment.

Those aircraft require a clear-water rinse at least every 15 days unless they have already been washed.

The same guidance establishes a 30-day aircraft wash interval for locations within 1.25 miles of salt water.

Why?

Because salt contamination does not need to become visually dramatic before it deserves attention.

The objective is to remove contamination on a preventive schedule rather than waiting for visible deterioration to determine when cleaning is necessary.

WHY THIS MATTERS IN FLORIDA

For aircraft operating in Florida, this concept is particularly relevant.

Florida combines several conditions associated with elevated corrosion exposure:

High humidity. Coastal salt. Frequent rainfall. Heat. Condensation. Exhaust residue. Bugs. Oils. Ramp contamination.

Aircraft may also move repeatedly between coastal airports, inland airports, outdoor ramps, and hangars.

An aircraft does not need to be based directly beside the ocean for environmental exposure to accumulate over time.

This is why the question should not simply be:

“Does the aircraft look dirty enough to wash?”

A better question is:

“What environment has this aircraft been operating in since its last cleaning?”

WHY WAITING FOR VISIBLE DIRT CAN BE THE WRONG STANDARD

Visible dirt is useful—it tells us contamination has accumulated.

But not every contaminant is immediately obvious.

A thin film of salt or environmental residue may be far less noticeable than bugs across a leading edge or exhaust staining underneath an aircraft.

That creates an important distinction between appearance-based detailing and preventive aircraft care.

Appearance-based detailing reacts to what can be seen.

Preventive aircraft care considers what the aircraft has been exposed to.

THE JETREADY APPROACH: CONSISTENCY OVER CORRECTION

Understanding that contamination accumulates continuously changes the way aircraft care should be approached.

Rather than waiting until an aircraft looks dirty, JetReady’s Aircraft Maintenance & Preservation Program allows owners, operators, and flight departments to establish a recurring cleaning schedule based on how the aircraft is actually operated.

Our program can be structured around:

After Every Trip
Weekly
Bi-Weekly
Monthly
Quarterly
Custom operating schedules

The objective is simple:

Manage contamination while it is manageable instead of waiting for heavy accumulation to determine when the aircraft receives attention.

FREQUENCY SHOULD ALSO REWARD CONSISTENCY

Recurring aircraft care is more efficient for both the aircraft and the operation.

JetReady therefore provides preferred pricing based on service frequency:

Monthly Maintenance — 5% Preferred Pricing
Bi-Weekly Maintenance — 10% Preferred Pricing
Weekly / Fleet Maintenance — 15% Preferred Pricing

The more consistently an aircraft is maintained, the easier it becomes to control bugs, exhaust residue, belly contamination, environmental film, and other recurring deposits before they develop into heavier cleaning requirements.

AIRCRAFT CARE WITHOUT THE ADMINISTRATIVE FRICTION

Consistency also requires making the program easy to manage.

JetReady recurring clients have access to our online Client Hub, giving owners and operators one centralized place to manage their relationship with JetReady.

From a phone or computer, clients can review upcoming and previous appointments, approve quotes, view invoices, make payments, access records, and request additional service.

There is no complicated scheduling process or separate paperwork trail every time the aircraft needs attention.

The goal is to make recurring aircraft care operate like a professional maintenance program:

Scheduled. Documented. Accessible. Repeatable.

CONTROLLED RINSELESS MAINTENANCE CLEANING

For appropriate aircraft and operating conditions, JetReady utilizes a controlled rinse-less wash process as part of recurring maintenance.

Instead of introducing large quantities of water simply because an aircraft is being washed, our objective is to use the moisture necessary to safely remove contamination while maintaining greater control around aircraft surfaces and sensitive areas.

That makes frequent maintenance cleaning practical while supporting JetReady’s broader philosophy:

Use the least aggressive process necessary to achieve the required result.

FROM OCCASIONAL DETAILING TO AIRCRAFT PRESERVATION

A recurring program changes the relationship from:

Dirty Aircraft → Corrective Detail

to:

Exposure → Scheduled Care → Contamination Removal → Continued Preservation

That is the fundamental difference between occasional appearance-based detailing and a disciplined aircraft-care program.

Consistency becomes part of the preservation strategy—not simply a matter of appearance.

MAINTENANCE CLEANING IS NOT CORROSION MAINTENANCE

There is an important distinction.

FAA and military corrosion programs involve far more than washing. They include inspection, preservation, lubrication, treatment, documentation, and maintenance procedures performed by appropriately qualified personnel.

Professional aircraft detailing does not replace those responsibilities.

JetReady does not diagnose or repair corrosion.

Our role is to support aircraft preservation through disciplined contamination removal and controlled cleaning.

If corrosion, damaged coatings, unusual staining, compromised fasteners, or another maintenance concern becomes visible during service, it should be evaluated by qualified aircraft maintenance personnel.

THE LESSON FROM MILITARY AVIATION

The most important lesson is not that every civilian aircraft should follow a military wash schedule.

It is that sophisticated aviation organizations do not necessarily wait for an aircraft to look dirty before taking action.

Environmental exposure helps determine the maintenance interval.

For aircraft operating regularly in Florida’s coastal environment, a consistent cleaning program can therefore make considerably more sense than occasional appearance-driven detailing.

KEY TAKEAWAY

Aircraft cleaning frequency should reflect exposure—not simply appearance. In severe environments, aviation corrosion-control guidance can call for preventive attention measured in weeks, not months.
