Hi folks. What cd/dvd cleaners have you used that actually worked? Is there anything that will actually fix small scratches, or is removing fingerprints and the like the best I can expect from these products? I've seen several in local electronics/computer stores, all from say $5-$35, and all about the same thing. You squirt some magic fluid on the disk, and either wipe it with a cloth by hand, or put it in a little case with a crank on the side that does the same thing. Is there anything better, before I spend my $20? thanks.
