Rain-X as CD Enhancement Treatment

I have used the Auric Illuminator treatment on my CD collection for several years now. I am a believer in the AI, and repeated A/B tests of identical treated/untreated CDs bore out significant improvements after treatment with AI.

I ran out of the fluid and my marker dried out, so I was searching for mew treatments on the market before buying another AI kit or choosing something new. That's when I ran across this article by Greg Weaver at Soundstage, where he talks about having used Rain-X and a green marker(Staedtler Lumocolor 357, price about $3.00) as a treatment on his CDs to great effect.

Being the complete geek that I am, I had to try it for my self. I found the marker at Office Depot, and picked up a little bottle of Rain-X for $2.99. I treated a couple of CDs that I have ended up with duplicate copies of (Grant Green's Green Street, Frank Sinatra Sextet Live In Paris)and tested the Rain-X/marker treated vs. untreated disks.

Well, low and behold, the treated disks sounded notably improved; the music was clearer and louder, especially the midrange, the soundstage was larger with better definition and separation of instruments and the bass was tighter and deeper.

I can't say that the Rain-X treatment was or was not better sounding than the AI, but at the least very it is close, for a fraction of the price.

Has anyone else ever tried the Rain-X treatment?

Tbg...Yes, but all you would prove is that each disc was copied without error, but they could be different discs.
What is needed is software that will compare two files that have been read into the computer as you suggest, one file before disc treatment and one after.

This would be a lot of number crunching! However, just the first minute of music would comprise 5.28 million bits, and the handwriting should be on the wall by that point.

Eldartford, what does the WAV databass contain and what is the confidence level in this comparison? What does "zero errors" mean?

I am a social scientists and find it quite curious that many who profess to value science, refuse to listen

...science does not value ambiguous individual human subjective interpretation/opinions.

Either...

Perform a controlled double blind test with a large population and with a meaningful result with statistical confidence.

or...

Provide a plausable scientific explanation for your miraculous claims.

or...

measure a difference with an instrument and allow others to repeat and verify your experimental results.

Any of the above would be valued by a scientist.

Someone who values science would not waste time looking at just any old wacky idea. There has to be some logic....some reasoning...some proof...some plausability.

Roger Ohlhausen's 1971 patent states that the active ingredients include between 2.5 and 30% mineral acids. Polysiloxane is the main ingredient, the acid helps with adhesion to glass.

Will these acids affect the plastic of the CD?

Shadorne, I think what you have said evidences your not being a scientist. If you are, you have little experience in the development of early ventures into research in an area. Also, you seem woefully unaware of validity issues in operationalizing concepts and variables. I strongly suggest you read the Ghost Map about the cholera outbreak in London. You will see where a hidebound, unfounded commitment to an explanation or theory can dampen our understanding of nature.
