Hmmmm. Is it capable of cleaning the lettering, for instance on a Leica lens ?
I think I'd find myself being somewhat squeamish about using it on optical 
surfaces although the (possible) Leica-sanctioned mixture that I mentioned 
would probably not be much less nasty.
Thanks
Dave

For a few years I was buying, fixing up if necessary, trying out and then 
selling classic cameras.
I've used lighter fluid on practically all of them (lenses, bodies and 
mechanisms) without any adverse effects.

If Leica approved a home brew for a lens cleaner, I'd wager the recipe
is 40 years old.  I doubt current management would stand by it.

Brush off the dust, breathe vapor on it, and use a clean microfiber
cloth on it.
