Do CD players need to be cleaned? If so, how?

Yes, most CD players should be cleaned if the CD tray (if ejectable as in multi-disk players) is left open or if the top cover was left open. This may cause an accumulation of dust and dirt on the lens or "eye" of the player, causing the player to be unable to read the disk. Also CD players should be cleaned yearly, to clean out the build-up of dust and lint inside the player, which may cause malfunction of moving parts. Both typed of these problems may be fixed by calling your local electronics store and taking it in to be cleaned.
