Agree with Chris here.
Spit is probably better than WD40.

It is a PENETRANT, NOT a lubricant. It penetrates into everything. It dissolves and ruins real lubricants, it can ruin optical coatings, it can ruin circuit boards, and it can actually accelerate
corrosion.
A drop of LUBRICANT in counterweight shaft threads is good. Cleaning dirty, contaminated threads with a toothbrush is good. And doing both is even more goodness. LOL.
Using a [slightly oily] rag to clean shaft threads before assembly might do the trick as well. Place rag around threads, grab rag and threads and then "unscrew" the threads from the rag and your hand.
If your threads are really dirty with something that is really stuck to them, a metal brush and some Break-Free CLP might be required. Followed by the old "unscrew from an oily rag" trick. (Nod to Don Adams.)
Currently my favorite lubricant is Break-Free CLP (the older brown formula over the newer blue formula) but there are lots of good lubes out there for various applications.
