Came across this at work today. Thought it interesting. A small magazine recently published an article on penetrating oils. They tested popular penetrants for break out torque on rusted nuts. These are the results. Penetrating oil average torque load to loosen: No oil... 516 pounds WD-40... 238 pounds PB Blaster... 214 pounds Liquid Wrench...127 pounds Kano Kroil...106 pounds Acetone/ATF Mix...106 pounds (Acetone mix is 50/50 and you can use lacquer thinner in place of acetone). I assume pounds is refering to foot pounds not inch pounds but then I'm not that smart. Any thoughts on this or penetrants not listed?
