I have not worked out a perfect process yet but the holder I have not had any problems with. I use two pair of pliers and just contort it a bit and the lens will fall out as the glue breaks away from the holder. There lies the problem. The glue comes off the holder first not the lens which leaves you scraping it off the lens. I really don't like having to do it that way.
It would be awesome if there was a solution that I can submerge the whole retainer in that will remove the glue but not harm the lens or AR coating. Or if heat could be applied to soften the glue without hurting it.
Anyone have any thoughts?
