[Leica] Cleaner older Leica lenses

[len-001 at verizon.net (Leonard Taupier)]

Tom,

Unless absolutely necessary I only use air forced from a rubber bulb  
to clean my lenses. The less scrubbing the better.

As for your old lenses, look through them with a flashlight shining  
into the front element. You'll find out very quickly how much damage  
was done. But do you really want to know? It can look pretty scary.
