Are there any really good cd cleaners out there?

Another vote for L'Art du Son -- more than just a cleaner, a once over with this is a must even for brand new CDs

rub in small circular motions

I have mostly read CDs should be wiped from the center out and not with the direction they spin.  I haven't read doing it with small circular motions. Does it really matter which direction you wipe them as long as you don't overdo it?  Anyone else with specific recommendations? Just trying to learn something.

I have always had best results with the circle method but others may find success in other ways but make sure it is the lightest of touches and also use a natural sponge as they tend ro remain cleaner for longer and I find they are not so prone to picking up grit.

Dish soap is just fine, and if you want to treat it for better sonics afterwards, use Auric Illuminator.
