i use tri-flow, kroil and liquid wrench...
I can't stand the smell of Ballistol, but it's good stuff for firearm related items.
Acetone and atf may get the job done, but acetone is some nasty stuff. Avoid flames and inhalation/skin contact if you can.
This has been discussed here before in the past but it may have been awhile. Look at this:
Penetrating oil comparisons
For all of you that are mechanically inclined..... Penetrating Oils Compared A study done by Machinist's Workshop magazine in their April 2007 issue looked at different penetrating oils to see which one did the best job of removing a rusted bolt by measuring the pounds of torque required to loosen the bolt once treated. If the study was scientifically accurate, it turns out a home brew works best! Here's the summary of the test results:
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
The Automatic Transmission fluid (ATF)-Acetone mix was a "home brew" mix of 50 - 50 automatic transmission fluid and acetone. Note the "home brew" was better than any commercial product in this one particular test. A local machinist group mixed up a batch and all now use it with equally good results. Note also that "Liquid Wrench" is about as good as "Kroil" for about 20% of the price.
I've used the ATF-Acetone mix and can say it worked when heat, WD-40 (no surprise) and breaker bars didn't. It's readily available, cheap and you just mix up enough for what you need. Why pay $$$ and have to internet order something else?
I like the smell.
A good penetrant is ATF mixed with acetone. I have it in a spray bottle. Shake and spray...
