Bearing lubricant

[Carman Gentile]

   I use Joy's Rust-Solv as a bearing lubricant and it works very well;
it really helps assist the strings' excursion over pressure bars,
through agraffes, etc.  But some of my customers don't like the smell it
leaves.

  What do YOU folks recommend for a bearing lubricant which is odorless
and safe for the strings?
