Professionals say that nothing will help a really dried out cartridge and
that once it is dead it is dead. But I have had some luck with Pelikan Ink
cleaner (ammonia or possibly window cleaner might do the job fairly well as
well).
I turn the cartridge upside down, put a few drops on the heads, cover to
stop the liquid from evaporating and leave overnight. Then you will have to
prime it to draw ink through the heads as the clear liquid you left on top
overnight will have penetrated slightly into the cartridge (and hopefully
'un-dried' the ink at the bottom) if the method has worked
