In the past I have used white lithium grease but I dont like the white residue against the black stabilizer. And it does collect dirt and gunk. Wiping off the excess is a dirty job.
I've also used WD-40 in a pinch.
Lately I've been using the same silicone spray I use on my slideout rails.
Sprays will drip wherever used so I try to cover the area as best I can with a utility tarp and then wipe down the tarp with paper towels for the next miscellaneous job.
I think the important thing is to lubricate them with something and run them up and down a few times to get it all coated.
