Aw right, time to bring what could be a very enlightening thread into a serious vein for a moment.
I'm known at work and home as: "Don't touch my screen," referring to my notebooks' screens. I'm so anal on that topic that it's become a joke to all around me. I cringe when I see people pointing their phalanges right into their soft LCD screens. Heck, I forbid my cleaning lady from cleaning my plasma TV and my other LCD TVs.
One time, when my kids were younger (and my hair was a nice dark brown) I was sitting in a hallway of a school while my then 10 year old daughter (now 17 and driving, and driving my wife and me crazy) was practicing with her basketball team. I was doing work on my laptop, when a woman walked up to me laughing.
She said to me, "I just said to your daughter, 'is that your dad outside working on that computer? It's very nice.'"
She tells me my daughter said to her, "Oh, yes, it is. And you can feel free to go over and look at it, but whatever you do, don't touch the screen,'" and the woman walked away laughing.
let me bring this back around to the thread. I never, ever touch my elements on my lenses and will almost emasculate anyone who attempts to. Therefore, I very rarely, if ever, need to clean my lenses.
