What CD cleaner to use?

After all of these years, I still use a dab of Windex (original).
Never heard nor seen any damage.

Happy Listening!

The best CD cleaner is L’Art du Son i have tried many this is by far the best.

  There are cases where I use a cleaner. When I do use a cleaner, I just use a spray intended for my glasses. Otherwise, I will just rinse them under hot water , and carefully dry them off with terry cloth, from center to outer edge. Most important to me is not to make any scratches. If you do, it is better that they are radial scratches rather than circular, i.e. in line with the laser tracking the disc.

Best I ever used was Intron Protect from Nanotec Systems out of Japan. Unfortunately haven't been able to find any more. CDs that would not play after a few skirts played without any issues.

Another Shinola guy here.
Been using it for years.
