I really like White Lithium Crayons like this for vises:

It is not sticky and will not trap dust or other filings. Just rub the end along
the thread and any wear points.  It is essentially white lithium grease in a wax

Kirk,

That raises a question in my mind:  What's the most appropriate lubricant for a
