It's just the rubber seal that's gone right? If the glass itself is viable why not just use solvent and some elbow grease to clean them up, chuck 'em in the oven to sterilise and then buy new kilner clip top caps? You can get them as accessories only in most cook shops (Steamer Trading do them down in Brighton, presume Nisbetts will in London, Lakeland etc).
I've never seen the seal go quite so dramatically though so presume there was something left on it that ate away.
