Fire damage can be devastating, leaving behind soot, stains, and a pervasive odor that can linger for months. Cleaning fire-damaged walls is a critical step in restoring your home to its former state. This guide provides a step-by-step approach to effectively clean fire-damaged walls, and also Fire Damage Restoration  ensuring they look and smell fresh again.

Assess the Damage

Before starting any cleaning process, it's important to assess the extent of the damage. This includes checking for structural damage, the severity of soot and smoke stains, and any underlying issues such as water damage from firefighting efforts. Consulting a professional might be necessary for severe cases to ensure the structural integrity of the building.

Gather Necessary Supplies

For effective cleaning, you will need the following supplies:

  • Personal protective equipment (gloves, masks, and goggles)
  • Dry cleaning sponges
  • Trisodium phosphate (TSP) or a TSP substitute
  • Buckets
  • Warm water
  • Clean cloths or sponges
  • Baking soda
  • Vinegar
  • Paint (if necessary for repainting)
  • Odor neutralizers or air purifiers

Safety Precautions

Safety is paramount when dealing with fire damage and Water Damage Restoration Services. Wear gloves, masks, and goggles to protect yourself from harmful chemicals and soot particles. Ensure the area is well-ventilated by opening windows and using fans to circulate air.

Dry Cleaning Sponges

Start by using dry cleaning sponges to remove the bulk of the soot and ash. These sponges are designed to lift soot off surfaces without smearing it. Gently wipe the walls with the sponge in one direction, frequently rotating the sponge to avoid re-depositing soot. Do not use water at this stage, as it can cause the soot to smear and stain the walls further.

Washing with Trisodium Phosphate (TSP)

Trisodium phosphate (TSP) is a powerful cleaning agent effective in removing soot and smoke stains. Prepare a cleaning solution by mixing TSP with warm water according to the manufacturer's instructions. Dip a clean cloth or sponge into the solution and wring it out well to avoid dripping.

Start washing the walls from the bottom up. This technique helps prevent streaking. Apply gentle pressure and use circular motions to scrub the stains. Rinse the walls with clean water and a separate cloth to remove any TSP residue. Be thorough in rinsing, as TSP can leave a film that may interfere with paint adhesion if you plan to repaint.


After cleaning the walls, the smoke odor may still linger. Baking soda and vinegar are excellent natural deodorizers. Place bowls of baking soda or vinegar around the room to absorb odors. Additionally, wiping down the walls with a vinegar and water solution can help neutralize lingering smells.

For more persistent odors, consider using commercial odor neutralizers or an ozone machine. An ozone machine releases ozone particles that can effectively eliminate smoke odors. However, ozone machines should be used with caution and the area should be vacated during operation.


In some cases, even after thorough cleaning, the walls may still have stains or discoloration. Repainting might be necessary. Before painting, ensure the walls are completely dry. Use a primer designed for smoke damage to seal any remaining stains and odors. After the primer has dried, apply a fresh coat of paint.

Preventing Future Damage

To minimize the risk of future fire damage, consider the following preventive measures:

  • Install smoke detectors and regularly check their batteries.
  • Keep fire extinguishers in easily accessible locations.
  • Practice safe cooking habits and never leave open flames unattended.
  • Create a fire escape plan and ensure all family members are familiar with it.


Cleaning fire-damaged walls is a meticulous process that requires patience and the right techniques. By following the steps outlined above, you can effectively remove soot, stains, and odors, restoring your home to a livable condition. Always prioritize safety, use the appropriate cleaning agents, and consider professional help for severe damage. With the right approach, your walls can be clean and fresh, free from the reminders of the fire incident.

By implementing these methods, not only will you enhance the aesthetic appeal of your home, but you will also ensure a healthier living environment free from harmful residues and unpleasant odors.
