How to Clean Soot Off Walls and Ceilings After Fire Damage

Soot Cleanup

Experiencing a fire in your home or business is already traumatic enough. What lingers afterward—the stubborn black marks, odors, and stains—is a daily reminder of that stress. One of the most common post-fire issues is the need to clean soot off walls and ceilings. If not handled properly, soot can cause permanent damage to your property and pose health risks.

Let’s walk you through the best ways to clean soot off and restore your space to its pre-fire glory.

What is Soot and Why is it a Problem?

Before we dive into how to clean soot off, it’s important to understand what soot actually is. Soot is a black powdery or flaky substance consisting largely of carbon. It’s created when materials don’t burn completely during a fire.

Soot can cling to virtually any surface—walls, ceilings, carpets, furniture, and even air ducts. The oily residue can smear when touched and spread quickly. It doesn’t just look bad—it can trigger respiratory problems and worsen asthma or allergies.

Step-by-Step: How to Clean Soot Off Walls and Ceilings

1. Safety First

Before attempting to clean soot off any surface, make sure the area is well-ventilated. Wear gloves, eye protection, and a mask. If the soot is extensive, consider calling professionals.

2. Dry Cleaning Sponge Method

Start with a dry cleaning sponge (also known as a chemical sponge). It’s made of vulcanized rubber and is designed to lift soot without water.

  • Gently wipe the wall in downward strokes.
  • Avoid scrubbing; you may smear the soot.
  • Replace sponge sides as they become black.

This method is excellent to clean soot off light or newly affected areas.

3. Vacuuming Soot Off

Use a vacuum with a HEPA filter and a brush attachment.

  • Hold the brush slightly off the surface.
  • Gently vacuum soot without pressing.

This method works well to clean soot off delicate painted walls and ceilings.

4. Use a Soot Cleaning Solution

Prepare a gentle solution of water, mild dish soap, and vinegar.

  • Dip a clean cloth or sponge into the solution.
  • Wring out excess water.
  • Lightly dab the surface—don’t soak it!
  • Rinse with a clean damp cloth.

This method is safe to clean soot off painted surfaces.

5. Trisodium Phosphate (TSP) for Tough Jobs

TSP is a heavy-duty cleaner ideal for stubborn soot stains. Use it with caution.

  • Mix 1 tablespoon of TSP with a gallon of warm water.
  • Use gloves and protective eyewear.
  • Test a small area first.
  • Wipe surface using a sponge, then rinse with clean water.

TSP is an aggressive cleaner to clean soot off older or deeply stained surfaces.

6. Baking Soda and Peroxide for Ceilings

Ceilings can be tricky. Use a mixture of hydrogen peroxide and baking soda to lift stains.

  • Spray the mixture lightly.
  • Let sit for a few minutes.
  • Gently wipe clean with a sponge.

This method is perfect to clean soot off acoustic tiles or textured ceilings.

7. When Paint Is the Only Solution

Sometimes, the only way to clean soot off is to repaint.

  • Clean the surface thoroughly first.
  • Use a stain-blocking primer.
  • Then apply two coats of paint.

Common Mistakes to Avoid When You Clean Soot Off

  • Don’t use regular household cleaners. Many of them can set the stain.
  • Avoid using water right away. Soot is oily and spreads easily with water.
  • Don’t scrub aggressively. This can embed soot deeper.

Why You Might Need a Professional
