Gabi,
        I'm afraid that if you want to remove the flux in the solder paste,
you must use a solvent that also removes the OSP coating.  So joint the rest
of us in the frothing sea and use IPA.  Just make sure you reprint that
board as soon as it is clean.  (Works great!).  By the way, if you use
no-clean, you will need to use an ultrasonic cleaner to avoid solderballs.
It is impossible to completely clean solder paste out of vias without it.

Thanks
