For applications like this, I find the dry-style spray-on motorcycle chain lubes to be near perfect; they don't attract dust once dry (a few minutes) and contain molybdenum disulfide, which is a good extreme pressure lube.
Prevents rust, too.... this stuff also works nicely in keeping the various moving parts in Airstream window latches, etc, working smoothly.
