What can be used as substitute to dichloromethane for breaking optical cement bonds? An optics supply company recommends using a dichloromethane solution to break bonds between optical elements joined with its UV-cured optical cement.1 The page mentions that dichloromethane-based paint strippers also work. Use of dichloromethane in paint strippers has been phased out in the USA  as of last year. Is there an obvious chemical property that dichloromethane possesses which causes it to break UV cement bonds and if so are there any more readily available hardware store chemicals which could be used as substitute?
According to an email i got back from Norland, &quot;It will work if the paint stripper has a chlorinated ketone in it&quot;
