You Will Need

  • A wire brush
  • A hammer
  • WD-40
  • A wrench
  • Safety goggles
  • A nut-splitter
  • A small blowtorch

Steps

  1. Step 1

    Brush off

    Loosen as much rust as possible off the nut with a wire brush.

  2. Step 2

    Tap

    Tap the sides of the nut with a hammer to help the rust separate and fall off.

  3. Step 3

    Apply heat

    Apply heat to the side of the nut for about a minute.

  4. A small, narrowly directed propane torch—one made especially for small jobs—will work best for this job, but be careful.

  5. Step 4

    Spray lubricant

    When the bolt is cool enough to touch, spray WD-40 on and around the nut and bolt.

  6. Step 5

    Tap

    Tap the end of the bolt with a hammer to loosen the threads and allow the oil to penetrate.

  7. Step 6

    Loosen

    Wait another minute or so for the oil to work, and then use your wrench to loosen.

  8. It sometimes helps to tighten the nut slightly and then try loosening it again.

  9. Step 7

    Split it

    If all else fails, buy a nut splitter and crack that sucker in half. Always wear safety goggles when using a splitter.

  10. Painting an object prevents rust from forming by blocking water and air from reaching the iron or steel surface.
