One of these will work. It might take a few days of letting the oil get down in there, but it will work.

Thanks, bkay. I'll see if I can pick PBblaster up here soon.
I turned my machine up like this so that the oil might be able to sink into the screw threads and what did I find up the pillar? An old mud wasp nest! Seriously!
