Interesting
For those of us in the rust belt now we can see what works best

Here is an interesting finding on Penetrating Oils
Recently “Machinist Workshop Magazine” did a test on penetrating oils. Using nuts and
bolts that they ‘scientifically rusted’ to a uniform degree by soaking in salt water, they then
tested the break-out torque required to loosen the nuts. They treated the nuts with a variety
of penetrants and measured the torque required to loosen them.
This is what they came up with:
Nothing: 516 lbs
WD-40: 238 lbs;
PB Blaster: 214 lbs;
Liquid Wrench: 127 lbs,
Kano Kroil: 106 lbs
The best and an old favorite
(ATF)/Acetone mix (50/50): 50 lbs.


This last “shop brew” of 50% automatic transmission fluid and 50% acetone appears to beat
out the commercially prepared products costing far more.

I thought shop brew would've been more like home brew with more kick :5SHOTS: :SOMBRERO:

Arguing about whether the glass is half full or half empty misses the point: the bartender cheated you.
