Lubricating metal vise screws?

I use wax on mine. Every coup0le of months, I wipe it down and clean with a stiff bristle brush the re-wax.

A little wax goes a long way. You don’t ever want to use grease or oil in a wood shop because it just gathers sawdust and clogs up. Wax and graphite are you best bet for most wood shop lubrication needs.

Wire brush the threads to get any gunk off then apply paste wax (NOT automotive wax) with a toothbrush, wipe off excess wax. Also need to lube whatever the vise uses to take the thrust from the screw. I use oil for that because can’t reach in there with wax.

Thank you all for your replies. Wax seemed like the best option to me.

I use wax and also spray graphite. The graphite doesn’t attract
junk and it is very slick.
