Having a coal-burning fireplace in your home adds warmth in a traditional and rustic way. However, fireplaces can bring unwanted dirt and stains to your home's carpets. You can extract these coal soot stains from your carpet. Remove soot stains as soon as you notice them. If you let soot stains sit on the carpet, it could permanently stain it. Contact a professional if you are unable to completely remove the stain. Soot stains are some of the hardest to remove, so be careful not to spread the stain or work it deeper into the carpet.
Sprinkle baking soda over the stain. Let it sit for 1 hour. The baking soda will absorb some of the soot stains from the carpet.
Vacuum the dry soot stain and the baking soda with the hose attachment of your vacuum. Do not run the vacuum over the stain as the pressure of the weight of the vacuum could push the stain deeper into the carpet. Vacuum from the outside of the stain toward the centre so that you don't press the soot further than the original stain boundaries.
Blot rubbing alcohol onto the soot stain with a clean, white cloth. Work from the edges of the stain toward the centre. Use a white cloth so that you can see the soot transfer to the cloth.
Apply 1 drop of liquid dish soap to the soot stain if it is still visible.
Blot the soap into the stain with a clean cloth until you've removed as much of the stain as possible.
Press a clean cloth into the solution to soak up as much of it as possible. If you leave cleaning solution residue on the carpet, it will change the carpet's texture and appearance.
Mist the area with clear water.
Press a cloth into the area to soak up the water and cleaning solutions.
