I've heard good things about this https://www.musicdirect.com/equipment/optrix-cd-cleaner-clarifier New thread... https://forum.audiogon.com/discussions/are-there-any-really-good-cd-cleaners-out-there?highlight=CD%... |
There was a CD treatment shootout quite some time ago. Lotions Eleven by the illustrious Clark Johnsen in Positive Feedback. It might have been updated to Lotions Twelve. Kind of been a while. 😳 I’ve had a lot of em over the years, Liquid Resolution was Top Dog, and would you believe I stumbled on my stash of Liquid Res just last week? Oh, my! I didn’t get off on Essence of Music. Optrix is OK. Jena Labs is very good. |
The best product I have seen for CDs is the AudioDesk CD Sound Improver. It trims and balances the CD so it has less jitter and is easier to read. We did tests ripping a CD and then ripping it again after using the AudioDesk. The CDs we tried all ripped around 10% quicker after the AudioDesk. Which means that there were less errors that had to be re-read. |
roberjerman Digital data storage is not analog-like at all! It exists independent of the physical properties of the storage medium! This is the revolutionary change in music storage and retrieval! Analog- like fixes do not apply (sprays, green pens, trimming the edges,weighted pucks, demagnitizers ... ). >>>>Actually, while it’s true the physical data on a CD is unalterable, the process of reading the data is an analog process, an optical process. And therein lies the problem. Because the laser reading process is not perfect, even with Reed Solomon codes and laser servo mechanism, the physical data is subject to misinterpretation/error caused by any of a variety of things, vibration of the CD transport, background scattered laser light, magnetic fields, static electric charge, and others, even the color of the CD label. Don’t be a digital denier. Join the thousands of happy campers who use vibration isolation, coloring of CD, beveling the edges of CDs, demagnetizers, static charge neutralizers, CD sprays, whatever they can think of to improve the sound. Don’t be an ostrich. Don’t be a cube, rube, go ape! |
@roberjerman +1 to Geoff pointing out the analog nature of the reading of the binary digital code. Any "tweaks" that enable your player or transport to read the digital data on your silver discs will yield sonic benefits. As far as "Spaying", I treat every CD or SACD with Rain-X. No, it's not just for windshields!💿📀 |
Light is not effected by magnetic fields so drop that as an issue for reading the CD, only after it has been converted to electrical signals will it be effected by the magnetic fields. vibrations, out of round, miss reads etc are the issues and no amount of snake oil on the CD will stop that. clean scratch free CD is the best we can do. |

static charge on the disk may cause induction in the electrical section after the optical system and may cause issues with the drive system if heavily ferrous. the drive system also has a motor that can be susceptible to the static charges. My feeling is the disk is rather benign (other then vibrations etc) in the system its what is effected around it that is probably what you hear. I think the better solution would be to remove the CD reading all together and go solid state drives and store the data on a NAS etc. but many are reluctant to give up their CD players yet. |

I've tried a multitude of sprays on my CDs including expensive ones like L'Art du Son. I've found the eyeglass cleaner fluid (under 3 bucks for a large spray bottle) sold at Walmart to be just as effective as anything else I've tried. In addition to cleaning the surface with the Walmart stuff, I demagnetize the CD with a Radio Shack video tape eraser. That's it ... for what its worth. Frank |
Static charge is a separate issue. Which is why ionizers or anti static sprays are often recommended. But static charge is not affected by demagnetizers. So we still have the dodgy problem of magnetism and why demagnetizing the CD improves the sound. This, ladies and germs, is looks like a real and legitimate mystery we have on our hands. |
