so I'm very new to all this, so I don't know a lot. My mountain bike will no longer shift gears, I've been told this is because my cables need lubricated, but I have no idea how to do this, so, how would I do that with a spray lubricant?

And please keep in mind, I don't really know anything about bikes.
