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?

I have used car wax on scratched dvd's (netflix) with success...remembering to wipe from center outwards.
It looks like the Rain-X treatment came to the fore about the same time as the green marker pen. I don't necessarily subscribe to the views in this article but it is interesting that this was in vogue about 18 years ago .
I just tried the stuff on one of those pesky, non-playing, scratched all to hell DVDs from the video rental store Friday nite. It worked just as well as my UltraBit Platinum(the disc played perfectly after treatment). This thread will save me a lot of money in UBP($4/bottle vs $65/bottle). It's in vogue for me as of two days ago. I'll save the UBP for my CDs.
Repairing scratches that cause skips is not the same thing as making a perfectly good disc sound better, or louder. Scratch repair is plausible.
Eldartford, you are correct; I have never used CD treatments as a repair method. My goal is entirely improved sonics. There seems to be some confusion here about scratch repairs and sonics. Any scratch repair in my usage of polishes is entirely incidental.

I wanted to clarify so that you do not think the challenge/concept of CD treatment stems mostly from repairs. My discussion pertains to the usage of disc treatments solely for change/improvement of the sound.
