beleive it or not...brake fluid will actually work alot better fot rusted and stuck bolts...i have used it on exhuast manifolds and such where pb just wasnt working...so keep that in mind.Use plenty of PB Blaster, and good luck.![]()
Did some searching around, and found these supposedly as the results of the
April 2007 Machinist's Workshop magazine comparison test.
Penetrating oil ..... Average load
None ..................... 516 pounds
WD-40 .................. 238 pounds
PB Blaster ............. 214 pounds
Liquid Wrench ..... 127 pounds
Kano Kroil ............ 106 pounds
ATF-Acetone mix....53 pounds
Looks like the homemade mix worked the best. Just keep it away from anything painted that you do not want to damage.
