Lens cleaning
Basically the lens on my G10 seems to have attracted some beer/lager drops and stains that seemed to have dried into a smear. I ahven;t noticed any discussions about such things here for quite a while so was wondering if there's any prefered methods or solutions (pun intented) Got me wire wool and bleach ready ;-) |

Sometime even a clean hanky and breath. If that wasn't adequate, try warm water (not letting it get into the lends, of course), and if not that /very/ mildly soapy warm water. Modern lens coatings are usually quite robust, but I suspect that not even Canon's would stand the wire wool treatment! G David |

Do you realize how much greassy crap comes flying out of your mouth when you breathe on your lens?

A lens cloth with a small area dampened should get this cleaned up without causing too much damage. There are also non-alcohol eye-glass lens cleaning fluids for use on non-glass lenses which you could use instead of water to dampen the cloth. -- Regards, Savageduck |

I purchase 8 oz. bottles from a surplus outfit for pennies. So inexpensive that I give bottles of it away. Best optics cleaner I've ever found and used. It'll even remove dried plant-saps from lens surfaces. The very best microfiber cloths are purchased as "Clean & Shine" cloths from Windex in your grocery store. 12, 11"x11" cloths for around $3 that can be cut into 4ths. They're much softer with an open-weave mesh that traps particles, it doesn't push the grit around like your standard tightly-woven 6"x6" microfiber cloths that you buy from a camera dealer for upwards of $10. So inexpensive that you can discard them after one or a few uses. I design my own lenses and have repaired many complex optics assemblies (right down to plan-apo phase contrast oil-immersion microscope objectives). I've tried and used all manner of cleaning methods. The best optics cleaning system can be had for under $5 and will last nearly a lifetime--IF you know what works best and where to buy it. Just more proof that "you get what you pay for" is a simpleton fool's claim. Just one more example of the kind of valuable information that you'll usually miss out on by being total asshole trolls. The only thing that has me puzzled is why I'm even sharing this valuable information with cretins that don't deserve help from anyone in the world at all. I'll never know. Perhaps for the 1 or 2 who might read this who don't deserve to suffer for you resident trolls being complete asswipes. |

I think the above is a "gross" exaggeration of things since the "acid" is VERY mild, and only VERY temporarily on the lens surface. BTW, if one breathes UP onto the down-facing lens surface, spit, etc. tend not to reach the lens surface, just the fogging moisture. I have used this method successfully for decades to clean lenses. For more difficult "glop" on the lens, I VERY SLIGHTLY moisten a Q-Tip with Windex (a window cleaner), then in turn use that to barely moisten another Q-Tip for the actual cleaning, finishing with breath and a good lens tissue (AFTER washing my hands with a dish washing detergent), WITHOUT silicone in it (that's horrible stuff to remove from a lens later, when it begins to fog). Some now prefer microfiber cloths for lens cleaning, though... --DR |

Like you, I have used this method for decades to clean lenses, and I have /never/ seen any ill effects. And I'm proud of my lenses, and would certainly not do anything to damage them. Modern lens coatings are relatively robust. Cheers, David |
