PB Blaster is the way to go if you can get it. It's the best penetrating oil I've ever used, and much better than WD-40 in that regard. WD-40 will work too. In either case, soak the screw with the oil, and don't be afraid to let it sit for a while. You may need to reapply the oil a few times. If it's a bolt, and not a screw, you can also use what's called a breaking bar on the end of a ratchet or wrench. Essentially, it's a metal tube that goes on the end of the wrench that gives you the ability to apply more torque to the bolt. With this approach, however, you may break the head off the bolt if the rusty threads aren't taken care of first.

First, soak it in penetrating oil (liquid wrench, WD-40, Pb Blaster...there's lots of brands.) A few hours is good - overnight is better. The oil will be soaked up by the rust, so add a little more just before unscrewing.
Next, insert the correct size screwdriver into the slot. The biggest problem here is using a screwdriver that is too small, which will blur the slot and make the job much harder, or one that's too big and doesn't fit all the way into the slot. Remember, the metal around the slot will be weakened by the rust.
Step 3: Hit the end of the screwdriver handle a few times firmly with a hammer. This will often help jar the screw free of the rust. Try turning the screw, always pushing in to ensure the screwdriver doesn't slip in the slot. If it does, try the hammer again. If nothing seems to be working, get yourself an impact screwdriver. These incorporate the jarring impact of the hammer with a twisting action at the same time - and they're pretty cheap. I don't know where I'd be without mine.
If none of this works, you'll have to drill it out, and then tap (cut threads in) the hole for a larger screw.

Yup, spray it good with any one of several lubricants available, such as Liquid wrench, wd-40, PbBlaster, etc.
And let it soak, 20-30 minutes to a couple of hours, overnight is good too. Sometimes you have to repeat the soaking by spraying it some more, I don't suppose you want to use the whole can, but nothing wrong with a squirt every hour or so, 2-3 applications should be good.
Patience, and lots of soaking lube.

Penetrating oil. There are several brands available. WD-40 has been around for an age. There are also other tools you can buy also. I have a manual impact that you can load with a screwdriver head bit and then you strike the head with a hammer and the impact will help break the screw loose.

soak it with WD40 and let it sit for a couple minutes, thats should help loosen it up. Try not to warp the screw though, then it makes it almost impossible, ha I know from experience
