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.*
*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.*
