There was an article in Machinist workshop about penetrating oils. If you want to see the original I have the magazine somewhere and can copy it. This is a post I copied off another site.

"The April/May 2007 edition of Machinist's Workshop did a test of penetrating oils where they measured the force required to loosen rusty test devices. Buy the issue if you want to see how they did the test. The results reported were interesting. The lower the number of pounds the better. Mighty interesting results for simple acetone and tranny fluid!

Penetrating oil . Average load .. Price per fluid ounce
None ................. 516 pounds .
WD-40 ............... 238 pounds .. $0.25
PB Blaster ........... 214 pounds .. $0.35
Liquid Wrench ..... 127 pounds .. $0.21
Kano Kroil ........... 106 pounds .. $0.75
ATF-Acetone mix.. 53 pounds .. $0.10

The ATF-Acetone mix was a 50/50 mix (1 to 1 ratio)."
Try some Automatic Transmission Fluid and Acetone. It was noticeably better.
