I have about 100 dishwashers with SS bodies that I am waiting to process. MOST of them have the heavy rubber/plastic insulation that is basically glued to the body. My yard says they are dirty ss, and will only take them as shred. Anyone have any ideas about removing this insulation? I have tried chisels and scrapers, but none of them work worth a flip. Sure would hate to have to turn them in as shred. There is one type of insulation that if I leave it out in the sun during the hotter days, it will fall off on its own. The other types, not so much, and it is these types that I am looking for suggestions.
