Well I pulled my derailleur apart so I could thoroughly clean my chain, only to find out that I've got ceramic bushings in one of my jockey wheels, and I don't know what kind of lube to use on them.

I wasn't expecting that - I thought both pulleys were sealed bearing and I could just clean around them as they probably don't need re-packing yet. But the whole thing came apart.

I sure would like to reassemble everything so I could go for a ride tomorrow! I don't have any bicycle-specific grease, so Deb or whoever, if you could specify the composition of whatever grease I need to use (moly paste, white lithium, etc.) that maybe I could get from the auto parts store, that would be a huge help! Thank you!
