Good Product or Nonsense?

I've been using Optrix for about 3 weeks now. I buy a lot of used cd's & know for sure they sound better when they are cleaned. Can't really say if there is an improvement using it on a "clean" cd or not. Also hope David is incorrect here because I've cleaned a couple dozen already... Good to hear inna and others haven't had any issues with it. 

Thanks for all the experiences! 
Does anyone know if there was a more recent legit review
that followed a scientific method? 

If not why?

If I wanted to do it the right way I would get, say, four copies of a well done cd and compared Optrix, LAST, Auric and Walker treatments. Yeah, maybe better not to use Optrix on valuable gold discs. I treated three gold cds with it but only two Mo-Fi ones gave me that haze, another one didn't. No idea why. 
I have a top loaded player and clean the lens with some Disc Doctor or whatever it is fluid that came with their cleaning disc. I rarely play the player these days, as I remember there was a small difference when cleaning every 50 hours or so. Maybe it was 100 hours, not sure.
I only compared Optrix treatment with washing the discs in warm water with kitchen soap. Yup, Optrix was better but soap and water was better than nothing.

Another +vote for eye glasses cleaner or windex for fingerprints/light scratches. I tend to buy used CDs weekly and have never experienced an ill effects. Rubbing alcohol and/or soap and warm water works well.

Happy Listening!

If using alcohol to clean CDs, I believe it should be highly diluted, as in lens cleaner.
And I would worry about preserving the polycarbonate coating if using Windex... 
the S.C. Johnson website lists Windex's ingredients as water, 2-hexoxyethanol, isopropanolamine, sodium dodecylbenzene sulfonate, lauramine oxide, ammonium hydroxide, fragrance, and Liquitint sky blue dye.
I'm not a chemist, so I don't know for sure. 

In any event, what is the consensus with using cleaner/clarifiers on the top (label) side of the disc?
