My friend uses these to wipe his laptop LCD and other surfaces. The cloth has antistatic properties and seems to do a good job at cleaning screens. Has anyone ever used these for their cam's LCD screen? I was thinking of buying one of these just to clean some dust/specks off of the LCD.

Any camera store should carry these cloths. I have a little package called "iClean" by Monster (as in Monster cables) that I picked up at the Apple store. It was under $20 I think and came with a nice little cloth and 2 bottles of cleaning spray that has lasted a very long time. It cleans very well and repels dust and lint and was specifically made for cleaning LCD's (laptop screens).
