Apparently this email  has been bouncing round the globe without reaching anyone
before returning to me. So I re-send it in case it might still be
useful...........

If the problem you have is ingress or retention of moisture (and associated
ionics) then no semi-aqueous process is going to be satisfactory as these
involve a water rinse. Some of the glycolether products aka oxygenated alcohols
- Prozone Dowanol Zestron etc- can be used solvent/solvent instead of
solvent/water, in addition some people rinse with  isopropanol instead of
water.( This is primarliy to get over drying problems.) You would have to take
account of the flammability of the IPA before going down this route.

 We are currently using Duriod 6002/6010 type PWB's on one of
          our products and are having problems cleaning the PWB's
          after soldering and assembly operations.  Removal of fluxes
          and the cleaning fluid (Axarel) from this very hygroscopic
          material has been difficult inspite of using the
          Manufacturers recommended process.  Any information
          or sources of potential information relating to resolving
          this situation would be appreciated.
