The only fluid I have ever used on my CD's is L'Art du Son and it has provided the most dramatic improvement in sound since I had my CEC TL-1X modded by RAM. The sound is fuller, richer, with less of the digital nasties in the high end, with great upper treble xtension and purity, and deeper, tighter bass. This really is amazing stuff, in my experience. I was skeptical, but hearing is believing.
