the best way I've found to remove rust from a bolt is to use CLR bath, tub, and tile cleaner.
If that doesn't take the rust out then you can try mixing some vinegar with a baking soda solution and make one of those not-to-scale volcanos. it's a great afternoon activity to enjoy with the little ones and it will probably remove the rust.

From experience on stubborn bolts on cars, you have a few options. With simple hand tools the best you can do it beat it off or round off the head. If you can get something to extend the length of your wrench (like small pipe) you can try a breaker bar. Use some penetrating oil first in any case(WD-40 or 10-in-1). With these methods there is a good chance you'll break the head off and the rest of the bolt will be stuck. You should try hot wrenching it. Heat it with a blowtorch then cool it off quickly with some water. The expansion and contraction of the metal may break the rust loose. If none of the above a Sawzall or a Dremel can be used to cut the head off. If you cut the head or break it off, you'll have to use an extractor to get it out. You can buy them at any hardware store (well known brand is EZ-Out). You have to drill a pilot hole first (which also means you need a bit for metal), then put your drill on reverse and use the extractor. It should grab the new hole you made and dig in until the bolt comes out. As much as you would rather not, your best bet is to use the blowtorch. Otherwise you run the risk of breaking the bolt or stripping the head which makes it all a lot harder.

If you have not already rounded the head I like to use heat and an air impact tool. That almost always works. If the head is already rounded then you may have to drill a hole in the center and use an easy out or bolt extractor. Worse case is you may have to drill out the screw completely and run a tap into the hole. Be very careful doing this because you have to drill exactly in the center and not go off on an angle. Sometimes this is best left for a machine shop but I have done it a few times in the garage with good results.

One method is to simply use a good impact wrench and socket (either air or electric powered) to break it loose. You may need to keep the bolt itself from turning by holding it with a big wrench while using the impact wrench on the nut. If the bolt snaps, simply replace the bolt and nut with a new one.

If you have access to a torch heat it up till its glowing red then start to remove it, you need to keep it as hot as possible to continue to remove it just make sure you dont catch anything on fire other wise WD40 can work but its going to take some time and effort

Hey mvtwin,
PB blaster is the bomb! Saturate the bolt and let it set for a few days. Works great!

PB Blaster is the best penetrating oil to use. If you can heat it up with a torch that will work or a hack saw. Good luck
