Anyone use CD tweaks

Pledge AntiStatic works great for CDs. The non-aerosol one that's safe for electronics. Far cheaper than any audiophile brand, and far better than anything I've used. For about $5, if it doesn't work as well, you can still use it for other stuff.

Spray a little on the disc, wipe it with a microfiber cloth, then buff with a dry microfiber cloth.

I have used various products and potions as well as mats. My best and FREE tweak is all I do now. Wash the cd with a little (very little) liquid soap and rinse well with water. I work the soap in with my fingers and rinse. Dry with a cheap paper towel so there is no lint. I have an R.O. system and I use the water from there, I don't know if it would matter though. It is an easily noticable difference. Clearer music across the board like a haze has been removed.

BlueMaxx cd cleaner is worth trying out, as well as Audiodesk

One of my favs is three 1 inch strips of black plastic tape on the label side arranged like spokes of a wheel.

The CD mat from Herbie's Audio Lab works great but sometimes gets stuck in the drawer mechanism, which is why i stopped using it. That, and it looses its ability to stay stuck after several uses and needs to be cleaned as a result. I believe its no longer available and has been replaced with a permanent stick on.
It really cleaned up the sound.
