CD sprays have been talked about before, but this is worth bringing up.
Here is a very inexpensive CD Tweak that I accidently found at my Lowe's Home Improvement Store.....
It's called "Plastic Cleaner" by Plaskolite, 8fl oz for $4.00 aprx! On the bottle it says "Restores plastic surfaces to bright finish, for use with Optix, Plexiglas, and other Acrylic Plastics." Also says Anti Static.
This stuff does wonders for the sound, more depth, clarity, punch, and a slightly fuller sound. Do a before and after and you will hear a difference, most of the time a good one. I sprayed it on both sides. I have not tried it on a DVD yet or SACD.
If anyone tries it, let me know how it goes. It's non flammable, non toxic, and there is no grit to it. It makes the cd surface shine like crazy.
