I was at our local drugstore not long ago and I came across a display of some Zeiss lens wipes, which are pre-moistened little towelettes designed to clean your glasses and, according to the box, your camera lens as well. Does anybody have any experience with these? They work fine on my glasses; they've never been cleaner, in fact. The name "Zeiss" leads me to believe they'd work ok for my camera lenses, but I thought I would poll the unwashed masses just to be sure. Thanks in advance for your input.
