<VV> Cynical Question on Acetone/ATF Mix

[jvhroberts at aol.com]

 Not to state the obvious...

1. Acetone is seriously volatile. With a BP of ~130F, it doesn't last very long. 
2. Acetone is hygroscopic. Not what you want for a rust penetrant. 
3. It will work if it's made up fresh, it simply won't last very long. 
4. From a commercial standpoint, why would anyone sell something this bloody flammable? 
5. Commercial rust penetrants use a variety of solvents/surfactants to increase 'wetting power' that don't have the problems of acetone.

I have heard of the 50/50 acetone/ATF (A/ATF) mix  before.  If this cheapo 
mix is twice as good as the best commercial stuff  and nearly five times as 
good as the worst commercial stuff, why hasn't  someone marketed the A/ATF 
stuff and swept the market?  In effect;  is the cheap stuff really that good?
 
Does anyone have a link to a real controlled test or is this  merely an 
urban myth?  I am just posing the question; I don't know.  I  think it would be 
difficult to make the claim the A/ATF liquid is twice as good  as the best 
commercial product (etc.) without a real statistically significant  
sampling.  This would require hundreds of identical nut and bolt  combinations 
with 
very controlled corrosion characteristics and expensive test  equipment.
 
Granted, even if the A/ATF stuff merely falls in the middle of  the 
commercial stuff, it is a viable alternative.  Bur I have seen no proof  that it 

even lies in the middle.  However, whatever its effectiveness, if  it isn't as 
good as the best of the commercial stuff you may give up on a stuck  nut 
prematurely.

A friend who is not a Corvair person  sent this to me. It sounds 
interesting.? Has anyone tried it?? What were your  results?
?

>From my motorhome  forum:

Most of us have had difficulty at one time or another with  loosening nuts 
or bolts,screws etc..I have been fooling around with a 50%  mixture of ATF 
and Acetone with terrific results . It is a lot cheaper as  well. 
The engineering tests on this are as listed: 
no oil....516  lbs
WD-40...238 lbs
PB blaster....214 lbs
Liquid wrench...127  lbs
Kano Kroil...106 lbs
ATF-Acetone mix...53 lbs
Lacquer thinner  seems to work as well.
I don't know who did the testing but this stuff  seems to work for me. I 
would like others to test this out as I can't believe  my results so far & I 
have no more frozen bolts screws etc. Perhaps you  could post to this forum 
with your personal  results
