Bugs, exhaust & oil stains
Work contamination wet, remove loose grit first, and separate removable residue from finish damage before escalating friction.
Aircraft
Surface care at aviation speed.
Aircraft surfaces combine demanding environments, high visibility, repeated contamination, and strict material considerations. Good aircraft detailing begins with identifying both the contaminant and the substrate before choosing chemistry or friction.
Aircraft problem library
Start with the exact aircraft surface problem.
Use the hub to move directly from the symptom or material to the appropriate process. Cleaning, correction, transparency care, and final protection are separate decisions.

Polish & surface protection
Use Koenig as the finishing polish and protection step after the surface has been cleaned, evaluated, and prepared.
Aircraft acrylic windows, windscreens & canopies
Identify the transparency material first, then use a conservative, scratch-aware cleaning and polishing process on compatible aircraft acrylic.
Oxidation, rust, water stains & scuffs
Distinguish removable residue from oxidation, corrosion, staining, transfer, and defects that require a separate correction decision.
Common conditions
Aircraft contamination is not one problem.
Leading-edge bugs
Bug residue can dry onto painted leading edges and other forward-facing surfaces. Repeated aggressive scrubbing can create its own defects, so dwell, lubrication, and controlled mechanical action matter.
Exhaust and belly residue
Exhaust deposits, oil-related films, and grime can build into complex contamination that may need a different approach from ordinary dust or wash residue.
Environmental fallout
Outdoor storage, ramp exposure, airborne particles, minerals, rain residue, and other fallout can remain bonded even after a routine wash.
Paint and clear finishes
Age, prior correction, repaint history, oxidation, and existing protection can all change how a finish responds to cleaning and polishing.
Polished metals
Metal surfaces require material-specific care. Oxidation, staining, and polishing marks should not be treated as if they were painted surfaces.
Transparencies
Acrylic and other aircraft transparencies can be particularly sensitive to incompatible cleaners, solvents, and abrasion. Manufacturer guidance takes priority.
Process
Separate cleaning, decontamination, correction, and protection.
The safest effective process is usually staged.
Begin by removing loose contamination. Then determine what remains bonded. Only after the surface condition is understood should more aggressive decontamination or correction be considered. Protection belongs at the end of that sequence, not as a substitute for preparation.
For aviation surfaces, material compatibility and aircraft or component manufacturer restrictions should be checked before using a chemical or abrasive process on an unfamiliar finish or transparency.
Protection
What should be evaluated after treatment.
Cleaning ease
Does bug residue, grime, or environmental fallout release more easily during subsequent maintenance?
Appearance
Track gloss, clarity, residue, streaking, and visible uniformity rather than relying on a single subjective impression.
Water behavior
Beading and roll-off can document a change in the outer surface, but they should be considered alongside cleaning ease and durability.
Durability
Repeat observations after washing and exposure. A treatment that looks impressive on day one still has to survive maintenance and environment.
Application effort
Time, residue removal, working area, and ease of use matter on large aircraft surfaces.
Material response
Watch for haze, staining, softening, gloss change, or other signs that a process is not compatible with the substrate.
Surface Lab
Aircraft is a primary test vertical.
Koenig’s history in aviation makes aircraft contamination, preparation, and maintenance an important Surface Lab focus. Planned testing includes bug residue, exhaust-related contamination, environmental fallout, cleaning effort, water behavior, gloss, and wash-cycle durability on appropriate representative surfaces.
