      Miller-Stephenson Chemical makes products for this purpose.  Their
MS-190 and MS-190HD (heavy duty) solvent flux removers are available in
aeresol spray cans.  MS-190HD contains trichlorotrifluoroethane, 
dichloromethane, and dichlorodifluoromethane.  These are somewhat safer
than MEK.  The exposure limit for MS-190HD is 629ppm, averaged over
eight hours.  (By comparison, the standard for dry cleaning fluid is
125ppm and may be dropped to 25 soon.)

      I've been quite satisfied with this stuff.  

      Cans of this are available at retail outlets in Silicon Valley.
Elsewhere, you could call Miller-Stephenson at 203-743-4447.
