Thanks! I found some old "Liquid Wrench Powerful Penetrating Oil" in the toolbox. Looks like it has a spray nozzle. Do you think that would be good? I don't mind buying a new oil, or even using something from the kitchen (coconut?) as long as it's a good solution.
Thanks again!
“Penetrating oil” sounds like a WD 40 competitor, meaning a solvent rather than a lubricant. A lithium grease is what I use for that sort of thing, which I happen to use the WD40 version of (it’s a yellow and gray there, rather than red and blue).
As jrbaconcheese said, penetrating oil is likely a solvent, designed to clean stuck joints rather than add lubricant. The greases are pretty good, however it may be difficult to work it into the hinge without disassembling it. PTFE sprays come with the nozzle though and are very thin liquids, so you might have better luck getting them in just by aiming in the gaps and working the hinge.
