I picked up the Dec. issue of Peterson's 4Wheel & Off Road. On page 96 there is a cleaner called "N-Terpinal". It looks to be a good replacement for some other cleaners/methods of removing rust/grease. Has any one used this stuff? The only drawback is that it works best at 120-145 degrees F.

I might pickup a gallon and try it on some parts I got laying around.
