If it has fish oil or vegetable oil in it, it'll get sticky as it oxidizes. If it's all mineral oil or lard oil, it won't. I'm not sure that it matters for this application.
I need something that will penetrate and will lubricate a little so I can get the cable to move in the housing. Then I'll probably pull it out and inspect it, and then not be able to get it back in.
PB Blaster, huh? Do I get that at a gun shop or Ace Hardware or an auto parts store?
