I use spray bicycle lube to clean it, but I wipe off as much as I can. I think less is more when it comes to lube on antennas. Mine has worked fine doing it this way since 1999 (nylon broke two years ago, but not for lack of lube, just got brittle), so I'm working on a new mast. I put lots of white lithium grease inside the motor when I changed masts.
