I would go with this:Im sorry, i had to. The title and word use just made me do it.
anyways...
I would go with WD-40 myself and I would do it the same way as mentioned already.
DONT just aim and spray. Even short quick bursts or anything you convince yourself will work due to laziness!
Ive seen people do that and basically over lube an ENTIRE machine... rather than the little area they wanted to hit.
its too bad that WD40 doesnt just come in a non aerosol can form as well.
