Those wipes are convenient, that's about it. If you don't use them often, they may dry up on you and then it's a waste of $.
I'm with lovin--Most of my CDs I will just run under the water and wipe them off on my jeans or T shirt. If it's a particularly dirty or sticky CD, then I may use good old IPA (i.e. rubbing alcohol) and a lint-free cloth.
If that won't get the job done, then most likely that CD is going to the trash and getting replaced.
