David Allen began his cleaning business at the age of 15, detailing automobiles with his best friend. Living near the Indianapolis Motor Speedway gave the opportunity to start a mobile washing service at the racetrack.

After high school, he continued his business of cleaning cars and traveling around the country while attending Indiana University.   It was at this point in 1991 that David formalized his business.

David has always had a passion for aviation and flying. While some only dream of flying, David made it a reality. David’s start in the Private Aviation Cleaning business came when one of his clients asked him to detail his single engine airplane (a Beechcraft Bonanza). Then, another client requested cleaning on his twin-engine airplane (a Mitsubishi MU-2.). It wasn’t long after that David completed and received his pilot’s license and his “first shot” at a corporate flight department...the rest is history.
