The BEST penetrating fluid is an easy DIY mix!

Post by DaleH »

FWIW the best penetrating oil one can use is a DIY homemade mix of 50% acetone and 50% automatic transmission fluid (ATF).

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

ATF/Acetone mix (50/50 mix): 50 lbs
