I would prefer one of the more fluid glycols over methanol but want to avoid the excess heat. I will let you know about the temp. BTW, since glycerol can be used (although in larger concentration) to prevent curling in paper, I wonder if either of the glycols might have a good effect on curling of paper of film? On second thought, the washing surely removes it so it probably doesn't. OT, propylene glycol is a great cerumenolytic (dissolves earwax) and can be used to good effect in cleaning out obstructed ears. Perhaps a good use for outdated HC110?
