At French Valley Airport, Subzero Surface Solutions performed precision dry ice blasting within the engine compartment of a Cessna 206 during scheduled maintenance. More than 2,000 hours of baked-on grease, oil residue, and operational buildup were removed quickly and efficiently without introducing moisture or abrasive media. Compared to traditional cleaning methods requiring solvents, countless rags, and trips to the wash rack, dry ice blasting dramatically reduced labor while preserving sensitive wiring, hoses, fittings, and surrounding finishes. The result was a clean engine compartment that improved inspection visibility and demonstrated the speed, precision, and maintenance advantages of cryogenic cleaning in general aviation..
