How to Remove Rusty Screws
- 1). Make sure you are using the right size screwdriver for the screw you are removing. A screwdriver that is too small, for instance, will not generate enough torque before it slips off the screw.
- 2). Spray the threads of the screw you can get to liberally with some liquid penetrant. Allow the penetrant to work for at least 15 minutes before continuing. If possible, drill a hole next to the screw to allow you to spray penetrant on the threads on the other side.
- 3). Dip the tip of the screwdriver in some valve lapping compound. This abrasive material will give the screwdriver more traction and bite on the screw head.
- 4). Use the cigar lighting torch to heat up the material in which the screw is stuck. Try not to heat the screw itself; you are attempting to expand the material around it so as to release the screw.
- 5). Set the screwdriver into the screw, and strike the back of the screwdriver firmly with a hammer to loosen the screw and knock off the rust and corrosion.
- 6). Try turning the screw clockwise (tighten) first, then backing it out counterclockwise. The screw will often turn this direction, and then you can gain a little momentum to go back the other way.
