Am repurposing roof with windows of a Polar Express puppet car and need to completely remove the marionette window silhouettes. Any suggestions on most efficient way to completely remove them without discoloring, hazing, scuffing or marring or degrading the white plastic they're imprinted on? Need to completely remove them so that no noticeable trace or shadow of silhouettes is left. Would appreciate hearing method(s) you've used to successfully remove similar silhouettes from current Lionel baby madison cars. Thanks
