What I use (since I always have it around anyways) is bike chain lube.
Shimano Slippery Spitt - even comes with the little piece of spaghetti for
getting into tight places.  Fantastic stuff - designed to penetrate into
chain links, and wick itself along cables, etc.  Comes in a little (about 2
oz???) bottle.  For the price, it'll last forever.

YMMV
