There are folks out there that rub WD40 on their
bodies for arthritis.
It did attack the plastic. The PTO by the way (which
was replaced with a used spare) ended up in my junk

was dropped on the knob and the shaft pushed the
plastic bushing out of the back. Another one was so
worn that vernier spring pushed the knob right out on
the owners desk.
