Caig pro gold works well and not expensive, I use it on interconnects, speaker terminals and even tube pins.
I've had good luck with the Walker silver paste, but use it very sparingly. I find it works well on fuse holders where additional contact is beneficial and there is little chance of the silver creating a short. So far I've been hesitant to put the silver on output tube pins of my VTL 750 amps.
For cleaning without adding any treatment, ordinary alcohol works very well. Just be careful to avoid splashing it around stereo equipment that's powered up. A friend of mine spilled a very small amount of alcohol into the chassis vents of an Aesthetix Io and it ignited into full flame. I don't know what the repair cost was but it was not a pretty situation.
Anyway, Caig is safe and I don't know anyone who thinks it's bad for connections or sound.
