Rust Buster
I just got this E-mail from another forum that I visit, thought I would pass it along.
"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) = 50 lbs."
The "shop brew" of 50% automatic transmission fluid and 50% acetone
beat out the commercially prepared products costing far more.
I'm gonna give it a try, don't know how soon. If anyone has tried or tries before me, let us know how it works.

very interesting and thanks for posting this.pb blaster kind of like boils up on contact and gives the impression of an extreme chemical action taking place.most agree krill is the best but not as easy to find.atf is mentioned to free stuck lifters so who knows.i will give it a try on my next project.

I've used Kano Kroil for years. I'm not suprised by the rankings. It's kinda hard to find around here. I use WD 40 on items I want to protect from rusting or whenever I need to spray a larger area and don't want to 'waste' the Kroil.

Im a believer in kano kroil. Not saying the home brew will not work, but a spray can of kroil is convenient. Plus I've never had a fire using it around heated parts. Acetone, I'd be a bit hesitant.
