Kroil, Liquid Wrench, PB Blast, Knock R Loose, homemade mixture of ATF and Acetone, and others. Many folks swear by each of these. There are some fun video's on Youtube testing and comparing all of them. Personally, if something is really, really rusted to death, none of them usually get the job done. I tend to use PB Blast because it's cheap and available anywhere. Kroil is almost 10 times as expensive and hasn't worked any better for me at least. I work on rusty crap every day. Actually got a book for Christmas called the Rusty Nut Bible by Chas Newport. A 252 page book about how to remove rusty nuts and bolts. Learning a few new techniques to try. The number one lesson is to work slowly and carefully. Once the fastener is rounded off beyond recognition or broken off, the project gets much tougher. Good luck to everyone dealing with this kind of stuff. Here are a few pics of the rusty crap that comes into my shop every day.
