The only thing the owner's manual for my Blue Ox tow bar suggests to
"clean and lubricate" is the extendable arms "once a year." (You need
to remove the rubber boots to perform this task and use nylon
electrical ties to re-attach the boots.) My bar has a spherical joint
(it does not use a ball-hitch) that the manual explicitly says "do
not lubricate."
I did use some light oil on the 'hinges' at the RV end of the arms
because the then new tow bar was so stiff that it was near-impossible
to spread them to change from the storage position to the towing
position.
I have not lubricated the pins that go through the couplings on the
toad end. I will probably use WD-40 or some penetrating oil if the
pop-outs that hold the pins in place should even fail to operate
smoothly. Oil or grease on the pins are likely to simply attract road
dust and other dirt --- making their lubrication probably a negative
instead of a plus.
