Stuck bolts? See what helps the most

Machinist's Workshop magazine tested penetrants for break out torque on rusted nuts. 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 results are as follows;
Penetrating oil........... Average load
None ...................... 516 pounds
WD-40 .................... 238 pounds
PB Blaster ................ 214 pounds
Liquid Wrench ........... 127 pounds
Kano Kroil ................ 106 pounds
ATF-Acetone mix...........53 pounds
The ATF-Acetone mix was a "home brew" mix of 50-50 automatic transmission fluid and acetone.

Really useful info.
I've got a bolt that's cross threaded that I may have to drill out. I tried PB blaster and it didn't help. I should try one of the other options and probably some heat too.

Heat is good! And if the table is correct, using acetone and ATF should reduse the needed torque to remove the bolt by 75%, which is more than significant.

At your age they are probably hanging low enough that you should pay road tax for them :D  (I know mine does  (:))  )

Heat is good, but before you bust out a blowtorch, try a hair dryer. Works surprisingly well, less hazardous and at times open flames are just a no go.

Oh, boy! When they do get stuck you're really going to regret it.

Great info! Thanks for this.
 
For the record, stay well away from the tinfoil based hardware included with ERMAX parts.

Faffi. Try an acetone/2stroke oil mix ( some 2 stroke oils are not miscible with acetone) . I suspect an even better result. I THINK 2 stroke oil contains an oil surfactant. Methyl benzene ( acrylic general paint thinner) also can be substituted for acetone.
For really stubborn metal/metal Castor Oil based oil and petrol. let soak then hit with a heat source away from the mix entry point. castor oil when in the presence of heat runs TOWARDS to heat source insted of away.

Posts about nuts, pipe nipples, thrust washers, etc bring out the 8 year old in all of us. Thanks for the info and the laughs.

At the risk of sounding dumb, did you buy a windscreen from them? If so, which one?

Not at all.  I bought their under-tail and their rear-hugger. As for windscreen I tempted fate and tried the Chinese special (after another member bought one). Really dig the look of it...and everything lined up in application. ;)
