According to a piece a day or three ago in the WSJ, there is a company whose business model consists of spraying some kind of juice into a jet engine (even while at the ramp), have that engine spooled up for a minute or two, and then catch the toxic soup that drains out. Done a few times, all the crud that accumulates on the turbine blades disappears, thus allowing the engine to run cooler and use less Jet A. Supposed to pay for itself in two-week's operations, and millions for the airline over a year's time.
Forget the name, though. (My half-heimer's kicking in)
