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.
