I bought a Bedini Clarifier on Agon and I must admit that it seemed to "fix" couple of skipping Cd's. I tried it on some Cd's that were in good shape and nothing seemed to happen. After about 30 Cd's of varying age I came to the conclusion that it's just a fancy CD cleaning machine. It helped some Cd's that had trouble spots but didn't make a noticeable difference on most discs. I guess if you put that liquid on a CD and spin it around real fast some dirt comes out or something. 
Could well be.
Y'ever read Bedini's patent for the Clarifier? In it, he "proves" that simply spinning a CD in a magnetic field not only performs data compression, but also rearranges the data on the disc.
His "proof" begins with a Kodak PhotoCD.
He picks an image file on it and copies it to a directory on his hard drive. Then he "treats" the disc in his Clarifier, and copies the same image to another directory on his hard drive.
Here's where things get weird.
Instead of doing a file comparison directly on the two image files, he first converts them to PostScript files. Then he loads them up into a text editor. He counts the number of lines of text in the two files. The PostScript file of the image file from the treated disc has fewer lines. So clearly his Clarifier must have performed data compression.
Then he uses a utility in the text editor to show the differences bewteen the two files. There are significant differences. So clearly his Clarifier must have rearranged the data on the disc.
I tried doing the same thing. Only I didn't have a Clarifier so I just copied the same image file off a CD into two different directories without doing anything in between.
I then converted each file to PostScript.
Just doing a directory of the two files showed that they were of two different file sizes. And using the ol' DOS file comparison utility (fc.exe) I saw that there were significant difference between the two files.
Of course the "trick" here is that the PostScript algorithms used in various graphics programs don't create identical files even when the files are generated from the same image.
