Homemade Penetrating Oil

[EdK]

I don't know if this has been posted before but here it is.

"Machinist's Workshop" recently published information
on various penetrating oils. The magazine reports they
tested these products for "break out torque" on rusted nuts
and bolts.

A subjective test was made of popular penetrating oils,
with the unit of merit being the torque required to remove
the nut from a "scientifically rusted" bolt.


Average torque load to loosen nut:

No Oil used ........................ 516 foot pounds

WD-40 ..................... ........ 238 foot pounds

PB Blaster ......................... 214 foot pounds

Liquid Wrench ...................... 127 foot pounds

Kano Kroil ......................... 106 foot pounds

ATF/Acetone mix...................... 53 foot pounds


The ATF/Acetone mix is a "home brew" mix of 50/50
automatic transmission
fluid and acetone. Note this "home brew" released bolts
better than any
commercial product in this one particular test.


Our local machinist group mixed up a batch, and we all
now use it with
equally good results.

Note also that Liquid Wrench is almost as good as Kroil
for 20% of the price.

ATF/Acetone mix is best, but you can also use ATF and
lacquer thinner in a
50/50 mix.

ATF = Any type of Automatic Transmission Fluid
