Good old wheel bearing grease works just as well. One can will last for years! :)

No need for a special lube which most likely is more expensive.
A light film of wheel bearing grease works great and a plain old blue shop towel to remove the grease after use works wonders for cleaning off the ball and the shop towel can be tossed out.
Although I tend to store my hitch with the grease on the ball and wrap the ball in a plastic shopping bag. This keeps the ball from gaining any surface rust while not in use.
Pull it out of the bag, wipe off old grease and freshen up with a light layer of new grease. Put shop towel in the greasy bag and discard.
Been doing that for 25+ years.
