Poor mans WD-40

Postby vdubjim » Tue Oct 16, 2012 6:28 pm

Simply mix one part acetone and one part ATF in a re-fillable spray bottle and go to town. The idea is to thin the ATF with the acetone so it will penetrate and seep into and between surfaces. The acetone will evaporate, leaving the oil to do its job. Because the acetone evaporates so quickly, it's a good idea to mix this in small batches.

Skeptical? We were too. Then we did some poking around on Google and found that in the April 2007 issue of Machinist Workshop Magazine, they performed subjective independent testing of penetrating oils using a single steel bar with 1/2" x 20 nuts torqued to 50 ft/lbs and treated with a 10% salt water solution that was allowed to rust.

Listed are the chemicals tested and the respective required removal torque:


516 pounds


238 pounds

PB Blaster

214 pounds

Liquid Wrench

127 pounds

Kano Kroil

106 pounds

50/50 Acetone / ATF

53 pounds
