Empire Aircraft Detailing
Removes exhaust streaking, oil residue, and accumulated grime from aircraft belly and underside surfaces in San Jose and the San Francisco Bay Area. Buildup that standard washing does not fully clear. Restores panel appearance and supports inspection readiness. On-site at San Jose International (KSJC), Reid-Hillview (KRHV), Buchanan Field (KCCR), and every airport we serve.

Our Process
The belly and underside of an aircraft accumulate the heaviest contamination on the airframe, including exhaust streaking, oil and hydraulic residue, gear-well grime, and baked-on environmental buildup. A standard exterior wash does not fully clear this, which is why dedicated belly degreasing is a separate, more intensive service.
We use aviation-approved solvents and degreasers that break down oil, soot, and grime without harming paint, sealants, or dissimilar metals. Particular attention goes to exhaust stain patterns, gear wells, and hydraulic leak paths, working the contamination off the surface rather than smearing it.
A clean belly is not just cosmetic. Removing accumulated grime reveals panel surfaces, fasteners, and seams, supporting inspection readiness and making it easier to spot leaks, corrosion, or developing issues during maintenance events and pre-buys.
Belly degreasing can be performed as a standalone service or combined with a full exterior detail. For aircraft with heavy exhaust output, such as many turboprops and piston twins, we recommend building regular belly degreasing into the maintenance cycle.

Questions
The belly accumulates the heaviest contamination on the airframe that a standard exterior wash does not fully clear. Degreasing is a more intensive, dedicated process.

A clean belly makes a real difference during annual inspections, pre-buy evaluations, and routine maintenance checks. Removing accumulated exhaust and oil residue reveals the panel surfaces, fasteners, and seams that mechanics and inspectors need to see clearly. Empire Aircraft Detailing provides dedicated belly degreasing at every Bay Area airport we serve, timed to coordinate with your maintenance schedule. For turboprops and piston twins based at KSJC, KRHV, KCCR, and KLVK, regular belly degreasing is a smart investment in both presentation and inspection readiness.
In Depth
The belly of an aircraft collects the worst of everything — exhaust residue, oil film, hydraulic weep and the airborne grime that streaks aft from every opening. Left alone it bakes into a stubborn black film that not only looks poor but hides the very surfaces mechanics and buyers need to examine. Our belly degreasing service safely breaks down and removes that accumulated grime, revealing clean metal and composite underneath. For a pre-purchase inspection or an annual, a clean belly lets inspectors actually assess the aircraft, and it signals an owner who takes maintenance and condition seriously.
Degreasing an aircraft belly is not simply a matter of strong chemicals — the wrong products or careless technique can harm paint, seals and sensitive components. We use appropriate degreasers and methods that cut through oil and exhaust film while protecting the surfaces and fasteners around them, paying careful attention to static ports, drains and antennas. The work is completed on-site, so it can be timed to a maintenance event or a pre-sale detail. The result is a clean, presentable underside that complements a freshly detailed exterior and supports the inspections that matter to owners, operators and buyers alike.
