2 questions: I'm interested in a suggestion made in an article to spray an ink degradant onto the screen before reclamation to prevent the formation of a ghost image on the screen. Can someone tell me what kind of chemical is used as an ink degradant-and does this practice really work?

If not, is there a preferred alternative (other than cleaning and reclaiming the screen as soon as possible after use and the use of highly caustic compounds) screen printers use for ghost image removal? Can someone also tell me what screen printing application in particular uses predominantly solvent-based inks? (give product type and substrate if not obvious)?
