To those concerned about fine scratches on CDs using microfibre cloths (and I'm NOT singling out EOM), info at this guitar forum site might be of interest. It appears that not all microfibre is created equal.

Excerpt here:
"A good microfiber cloth like these will not harm your nitro finish, and in fact, they are less harmful than even soft cotton or flannel cloths. I learned this as a concours car guy with fine lacquer finishes. I use these on my nitro-finished Private Stock and my V12 stuff, and have no swirl marks:
The secret of a good fluffy cloth like this is that the filaments of the fabric are even finer than cotton fibers. You don't have to rub as hard.
It's easy enough to check - take a cotton cloth and rub it hard on something like a clear plastic CD case, then do a different spot with the microfiber. You'll see swirl marks where you used the cotton, and not the microfiber."
The microfibre cloth he's recommending is used for auto detailing.
