    Never be frustrated by a rusted nut and bolt again with this foolproof removal method.

    Step 1: Brush off
    Loosen as much rust as possible off the nut with a wire brush.

    Step 2: Tap
    Tap the sides of the nut with a hammer to help the rust separate and fall off.

    Step 3: Apply heat
    Apply heat to the side of the nut for about a minute.

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

    Step 4: Spray lubricant
    When the bolt is cool enough to touch, spray WD-40 on and around the nut and bolt.

    Step 5: Tap
    Tap the end of the bolt with a hammer to loosen the threads and allow the oil to penetrate.

    Step 6: Loosen
    Wait another minute or so for the oil to work, and then use your wrench to loosen.

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

    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.

    Did You Know?
    Painting an object prevents rust from forming by blocking water and air from reaching the iron or steel surface.
