How often does an aircraft belly need degreasing?

An aircraft belly needs degreasing at least once every full detail cycle. High-utilisation or oil-throwing airframes benefit from it between details too, because the job is quick when done regularly and slow when done rarely. Left in place, the exhaust and oil film is acidic, holds moisture against the skin and hides the seep lines maintenance needs to see.

Why does a clean belly matter for maintenance?

The belly is where corrosion starts and where leaks announce themselves. A degreased belly leaves seep and weep lines readable, so maintenance can see a new leak against clean paint. The FAA's Advisory Circular 43-4B, Corrosion Control for Aircraft, treats engine exhaust trail areas as prone to corrosion, and the belly's condition is photographed to the record after every job.

Is anything sprayed into static ports or drains during a belly degrease?

No. Around antennas, drain masts and static ports the belly is cleaned with distance kept, and no chemistry goes into drains or ports. After treatment, static ports and drains are checked by sight for residue, and anything found is reported to maintenance rather than handled by the detailing crew. The last check is a white towel wiped across the belly.

What is aircraft belly degreasing?

Belly degrease strips the exhaust soot, oil film and hydraulic residue that accumulate on the lower fuselage, then spot-treats staining. Left in place, the film is acidic, holds moisture against the skin, and hides seep lines maintenance needs to see.
