Unscrew A Rusted Nail
If you’re about to start fixing up very old bits and pieces around the house, the chances of you coming across at least a couple of corroded nails are high. If there’s ever the need to unscrew them, going straight at it with a screwdriver won’t help.
You will first have to get rid of the rust, which isn’t as challenging as you’d think. Start by cracking the rust with a few swift hammer blows. Then, prepare a solution with equal parts nail polish remover and transmission fluid or sewing machine oil. Apply the mix generously and let soak before proceeding with a few extra hammer blows. Finally, unscrew!
