    There are so many penetrating oils on the market its 
hard to know which, if any, work best. I strongly suspect 
there is not really much difference among them. WD-40 seems 
to be a combination of Kerosene and light oil, not a good 
lubricant and in my experience, only a fair penetrating oil. 
I find Liquid Wrench works better.  I also have PB Blaster 
and agree about the odor but it seems to work. I think at 
least some of these products must contain a reducing agent; 
that is something that reverses oxidation, but I have no 
specific information. They may also have something in them 
to make them "wick".
   The MSDS for these products will tell you a little 
something about their composition but MSDS are not required 
to show non-hazardous ingredients or even hazardous ones if 
present in very small amounts.
     FWIW, Diesel fuel is close to Kerosene.
