About a year ago I read an article where they tested different penetrating solutions to see which one was the best. I can't remember where exactly I read it but anyway....they applied all of the popular brands that we are all familiar with and one that they custom mixed to rusted nuts on a bolt. They let them all set for the same period of time(not sure of the time) and then they used a torq wrench to measure the amount of force needed to remove the rusted nut.

The winner........the custom mixure of.....50% acetone.....50% power steering fluid.

....and now you know the rest of the story.....Paul Harvey.....Good day!!
