    Make sure that the wood stove is cool and the firebox is empty.

  3. 3

    Use your duster and work top to bottom, left to right, finishing with the sides and base of the wood stove, to remove any dust, debris and loose residue.

    Use your wire brushes to scrape off any baked-on or difficult to remove dirt.

    For rust spots or calcified deposits on your cast iron wood stove, left by leaks or humidification, use metal-grade sandpaper and gently rub the spots away. Use the duster to clear the area of the particles you have scraped away.

    Use the toothbrush to scrape dirt and dust deposits from the corners and crevices of your cast iron wood stove.

  10. 10

    Wipe out the firebox with a clean rag, starting with the top and moving left to right, allowing any residue to fall to the bottom of the firebox. Use your wire brush to scrape away any grit.

    Re-vacuum the firebox.

  12. 12

    Scrape the grit and dirt off the grate using a wire brush before replacing it in the firebox.
