Could it be that if this is the case this build up on the plates could be removed? Is there a substance that would do this job ?

  That is the correct term (Sorta) sulphation is the bonding of elemental sulfur to the lead plates , Being relatively Non-Conductive it prevents the cell affected from charging properly. There have been witch doctor cures, Of which most cause more problems than they cure. (If there were a simple and reliable cure there would be no battery re-builders) The Main problem with chemical treatment, would be completely flushing the sulfuric acid from the substrates. Introducing a leaching agent to release the sulfur , Then Completely removing that from the substrates prior to reintroduction of normal electrolyte. Since the Substrates are much like Sponges, it would be nearly impossible without dissassembly. And if you're gonna go that far, Why not just Build-Rebuild it.Melt the lead, Sulpher releases, and floats on top. Skim it off. and re-cast your plates.
