Oiling the Z axis screw

I've noticed that there's one point, a little more than halfway down, where my platform is consistently producing a rubbing noise as it travels up and down the center screw. Any advice on lubricating this screw? I've got WD-40, lithium grease, etc, just curious if there are any thoughts on the best stuff to use in here.

I use Krytox or Saf-T-eze Anti-Seize or similar

Use this on the lead screw and rails. Cheap and the tube will last forever.

If you use anything you want something kinda thick otherwise it will just run off and disappear.

Don't use WD-40 use (in moderate) lithium grease.
