How do I lubricate these spring loaded hinges?
If dry graphite is problematic to apply you can also find it suspended in a liquid for use in locks. Lightweight oil or volatile lubricants flow into the lock leaving the suspended graphite behind when they evaporate. (Dry graphite, if you haven't had a reason to use it before, is also very easy to "shoot" by squeezing the tube. It's a very fine powder.)

A trip to the local hardware store will be a big help since you can see all of your options. "Zoom spout turbine oil" is probably not primarily used on turbines; I think people like the long, flexible tube.
