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.

I've used lighter fluid on practically all of them (lenses, bodies and mechanisms) without any adverse effects. ----- Original Message ---- From: Sonny Carter <sonc.hegr@xxxxxxxxx> To: leicareflex@xxxxxxxxxxxxx Sent: Sat, January 16, 2010 4:31:32 AM Subject: [LRflex] Re: formula for lens cleaning fluid 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.
