Do you have a TopSider or Mityvac? You could possibly use them to suck up the crud as well.
WORD OF WARNING: MAF cleaner fumes are most likely flammable. If they get sucked into a vacuum cleaner and come into contact with the sparking brushes in the motor you stand a chance of igniting them. Granted, it's not going to make a rocket engine (like the Mythbusters tried to do) but you could get a nasty surprise if they ignited.
Bobs: What a great word of warning... I had never considered that... MAF cleaner has a really low flash point especially when vaporized... perhaps I will just make a standalone vacuum bottle using my existing shop vac to prevent some sort of conversation with my wife saying "see I told you so".
