Good Product or Nonsense?

I’ve used a number of CD cleaners. I’ve found a really cheap way to go and its found in any Walmart optometry department. It’s their eyeglass lens cleaner. About two or three bucks per spray bottle. Just spray it on, then wipe with a lint-free cloth. Then use your demagnetizer.

I've tried a bunch of the after-market CD treatments. While some appear to "make the sound of digital sound more analog," by smoothing the sound, I've found that they remove some high frequencies. That's why I switched to a basic eyeglass lens cleaner. After cleaning, I use a Radio Shack DVD tape eraser to demagnetize the CD. 

I think it best to seek out recordings that were engineered correctly. If done properly, Redbook CD's sound amazing.
