How to clean a car CD player

[Count Duckula]

I haven't tried that one in particular, NB, but I do own a CD drive cleaner for my CD-ROM drive and CD boombox and portable CD player. The problem with that cleaning disk is that it has a brush that stands out from the disk itself. The CD player in my car has a slot just big enough to accept a CD, and I'm afraid that a brush like that would break off.
