WD-40 will work, but any of the true gun oils you can buy at a gun store or at Wal-mart will work better. WD-40 is a cleaner, not a lubricant, so clean, then follow up with an oil...
Here is a report on WD-40, it works, but not as well as other oils...

The "WD" stands for "water displacing," and WD-40 does that task well. That means it is good for hosing down and flushing out that duck gun that fell overboard, at least until you can get it home for a proper cleaning. However, WD-40 tends to gum and turn into a varnish with time. So WD-40 may be fine for an external wipe down, but it is potentially devastating to moving parts that require lubrication. In my experience, WD-40 has little, if any, lubricating properties, and is best left for its designed tasks.
