[V8] Kroil vs PB blaster vs etc.

[Mike Arman]

OK guys, here's the word:



this is forwarded from another list:

<quote>
Machinist's Workshop magazine actually tested penetrants for break
out torque on rusted nuts. Significant results! They arranged a subjective
test of all the popular penetrants with the control being the torque
required to remove the nut from a "scientifically rusted" environment.

Type of 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 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.
