Powdered graphite is an excellent lubricant that doesn't attract crud. My father had a little squeeze tube of it for locks; it eventually ran out and I haven't seen any more since.

You can find the small tubes at hobby stores, with the supplies for Pinewood Derby cars for Cub Scouts. I went through several tubes during my son's years in Scouts.

  You can also get it at hardware stores for lubricating locks.

    The versions for lubricating motorcycle cables are finer and less messy than the cheap stuff they sell for locks. If you want to be neater with your slide rule, anyway :)
