Just got this note from a cousin out in California . . .

---------------------------------------
Penetrating Oils Compared

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.

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.

------------------------------------------

Kool Data! I have a can of Kroil that's
left over from our airport days. Bought it to refurbish
some parts on our tractor/hedge-hogg. But it's
interesting to see that one can do better yet
with some off-the-shelf ingredients. Would
be interested in hearing from members on
the list who have tried the home brew.

Bob -

I have been using "the brew" now for about a year, and am astonished at
how well it works. Recently I was tearing down a washer for repair, and
the tub nut was frozen in place (aluminum). All the repair directions
said to cut it off with a chisel and replace. I soaked it in "the brew"
for around an hour, ever so often, giving it a couple of whacks around
the perimeter with a hammer and a drift. When I put the wrench on it,
off it came like it was new! I have used it side by side with Liquid
wrench, and it works twice as fast. Drawbacks are that it is very
flammable, has to be kept in a closed container (I use old shampoo
bottles with the snap over tops and a short length of vinyl tubing in
the hole for a spout), and will ruin a paint job in a hurry. I'm on a
couple of machinist's websites and put the info on both of them
recently. All my buddies are using it now.

Good Afternoon 'Lectric Bob,

I have been using Corrosion X for those purposes I wonder how it would fare on an equivalent test?

Happy Skies,

I would assume that this is the lubricant,
and the acetone is a strong solvent which carries it into the "nooks and
crannies" of the rusted assembly. Probably some other lubricant could be
used, but this apparently works!

In addition, ATF is a pretty good solvent in it's own right...besides lubricating, it can dissolve lacquers, corrosion and other hard to remove cruds. It is a recommended solvent for cleaning gun powder fouling in firearms.

So, I would think that between the acetone's properties of being thin and working into tiny spaces and being a solvent for most plastics, and the additional solvent properties of the ATF and it's ability to stay behind as a lubricant, it makes a good combination.

The containers of ATF do have warnings against getting it on your auto's finish...

Bob,
I had seen that note a few months ago. Over this last winter I had to replace an engine on a log splitter. Since it had been together for 25+ years, everything was pretty well rusted together. With nothing to lose, I tried the "home brew" and it worked exactly as advertised! I was working outside, and removing paint was not an issue, so none of the concerns expressed on the list were an issue for me. I was as surprised as anyone how well the brew worked. I certainly recommend it for seriously rusted together parts!

Hi Bob,

Thank you for forwarding this great info on. I was pondering this info while
driving into work this AM and came up with a couple of curiosity questions:

- How long were the assemblies exposed to the penetrants before applying the
torque (seconds, minutes, hours, days)?

- Is there any data for 'torque vs time' - ie. How much torque to break an
assembly vs time exposed to the penetrants?
Also, I would imagine that the assemblies would have to be _very_ clean before
re-assembling them - particularly for the 'home brew' stuff since it offers
nearly 10x reduction in torque.

Regards,
/\/elson

Here's one I have used a few times and it seems to work well. 1 oz of
wintergreen oil (available at a pharmacy) with 1/2 gal diesel fuel is
the formula I have seen. When I've used it, I mix small (<1oz) batches
of wintergreen and air tool oil ('cause it was close at hand and low
viscosity).

info while driving into work this AM and came up with a couple of
curiosity questions:

- How long were the assemblies exposed to the penetrants before
applying the torque (seconds, minutes, hours, days)?

I Did a web search on "ATF" and "acetone" and got a gob
of hits. Seems the original author of the article
did an update of the article but the website link
is broken. I think the site is defunct. Did find this
bit on at:

------------------------------
http://mytractorforum.com/showthread.php?t=99250
------------------------------
This same quote has been circulated over the internet for a while but
if you actually read the article you will find:

The scientifically rusted environment was just 12 hours in salt water.

No bolts, no nuts but just dowel pins rusted into a block of steel.

A 8 hour soaking in the penetrating oil not just a few sprays.

There was no ATF but it was a 50-50 mix of acetone and power steering fluid.
Power steering fluid and acetone do not mix well, it will separate
into two layers because acetone is relatively polar.

How valid was his study? From what I could tell from the article, it
was really not valid. I suggest getting a copy of the article and
deciding for your self.
-------------------------------

The ATF/Acetone thing is very widely spread
on 'net. Almost viral. A search on "power steering
fluid" and "acetone" yielded a bunch of articles
on hazardous waste disposal.

Would be interesting to pursue further but I'm painting
cabinets today . . .

I have teach some advanced high school classes where the students are always
looking for interesting projects for science fairs. This research might be a
good fit. What thoughts does anyone have on how to "scientifically" within a
reasonable time frame get a bunch of comparably rusted bolts? Also, any
ideas on what application protocol for the "nut busters" would be most
useful?

Dr. G,

I'd say you have at least two nice projects here.

1. Studying corrosion
Compare solutions of water, water with NaCl, water with CaCl, water
with both, on cheap, unplated, hardware bolts/nuts over time (days/
weeks/months).

2. Once you get a suitable set of corroded bolts/nuts, what works best
to separate them.

I'll think more about the necessary protocols until I return home and
can write more easily.

Regards,
Bob Borger
