Best CD/DVD cleaners & tweaks?

I have tried a couple of CD treatments, using duplicate CDs to test effectiveness, and Auric Illuminator is my choice. First let me say I am very reluctant to apply any treatment to my CDs, if you have been around for long enough you know the history of "great" tweaks, some irreversable, that turned out to be BS, and may actually degrade sound. I don't use AI on all CDs, although it is cheap, but about 1/2 of my rock/alt CDs have treatment......main benefit is to reduce digital grain/hardness, smoother sweeter sound with no detail loss......it will not work miracles, but it is worthwhile, and can be removed with some effort if needed......I also use Bedini II on all CDs before playing, regards Sam

Auric Illuminator is 2 step tweak........first black opaque pen used to blacken inner/outer edges of CD, 2nd blue gel is applied to both sides and buffed off......the claimed total effect is improved read of CD data for various reasons, and thus improved sound, Galen Carol sells kit for $34..........Bedini II is subject of much debate, "clarifies" CD by spinning over electromagnetic field, creates polarization of CD surface which produces cleaner sound, $149 from Galen Carol.......I know, plastic and aluminum aren't magnetic, but I detect improvement and AI/Bedini II combo is even more effective together...... again not a miracle, but worthwhile and shows largest improvement on avg/poor recordings, more subtle on already good recordings, regards Sam
