I own some older Kodak Ektar/Wollensak lenses for my Graflex cameras and, if the '50s Leica lenses have the same coating type, it is extraordinarily fragile and scratches *far* more easily than any modern coating I know of. I would never use anything on those coatings that required me to "press hard" and hope you'll consider using extreme caution when considering cleaning methods. For my 50's lenses, I use Q-tips and 91% isopropyl alcohol and almost zero pressure. After a microfiber cloth made many fine coating scratches, I had to find a way that worked and the above was the only way I've found that cleans to perfection and never scratches. Danny Gonzalez
