Most glazing putty uses linseed oil as the primary vehicle. Ordinary
paint stripper has been successfully used to soften old putty,
however depending on the treatment of the sash paint stripper may be
incompatible with the goals or techniques of the conservation
efforts.  If a gentler alternative is needed soaking with linseed
oil may work.  More information can be found at:
