Anyone use CD tweaks

I use Shinola, not sure I'd qualify it as a tweak though. It's simply a cleaner that IMO does a good job.

2chnlben,the Herbie CD mat is so light it wont have a negative effect on the RPM's,and it works the way you describe.
Tvad, my mat didnt work on my friends 3910 either.
The Herbie CD mat was the winner of a 'best cd tweak' in a thread from long ago.
Most,if not all that owned one said it works better than any cd tweak and does what it is described to do to improve the sound of cd's and sacd's
When I bought mine I think its was 20 bucks shipped.It may be up to $24 now.
Not sure if Herbie offers a return policy,but Im very sure anyone that tries it wont be returning it.
Herbie offers a lifetime warranty I do know. Even if your dog dines on it for lunch.
As I said before,Im surprised no one has mentioned this mat except me.

I use Pledge Anti-Static to clean my CDs. My results are pretty much what others have said regarding other cleaning/shining products. Very effective and cheap. A bottle cost me about $3 or so, and I've cleaned about 200 or so CDs with less than half the bottle.

Its the spray version (not aerosol) advertised to use with electronics.

I've been using the Marigo 3-D Stabilizer Mat (which is essentially a semi-rigid disc). I had used their original disc and am now using the newer design. They both work well also.
