How to Clean Smoke & Soot Off Walls & Ceiling

House fires, fireplaces, lit candles—all forms of fires can lead to smoke and soot collecting on home surfaces. The effects are more serious than just staining; smoke and soot present serious health risks, which is why prompt removal is so important. 

Cleaning smoke and soot can be difficult when the pollutants collect in hard-to-reach places, such as your walls and ceilings. This guide walks you through the cleaning process and provides recommended tools to use, along with some do’s and don’ts of smoke and soot cleaning. We’ll also discuss when it’s best to call a professional smoke and soot cleanup technician to get the job done. 

Preparing to Clean the Walls and Ceiling

Before beginning the cleaning process, there are a few preparatory steps you’ll need to take. The first is to wear the appropriate safety gear—including a face mask, safety goggles, and gloves—that help you avoid touching or inhaling smoke and soot particles. Next, you may want to put down a tarp to protect your floors during the cleaning process, particularly if there is a lot of soot on the ceiling. 

Proper ventilation is also essential. Open the windows to let in fresh air, and use fans to aid air circulation. It’s wise to turn off your HVAC system during the cleaning process so soot doesn’t get into your air ducts. That said, you should still check and clean your vents after soot cleaning.

Finally, have all of your cleaning supplies ready to use, and know the order in which to use them. Applying cleaning tools out of order may smear the soot and elongate the cleaning process.

Here is a complete list of the supplies you’ll need: 

  • Face mask 
  • Safety goggles
  • Gloves
  • A cover for the floor and any nearby furniture 
  • A powerful vacuum with a nozzle or crevice cleaner 
  • A stepladder
  • Dry soot sponge
  • Dish detergent solution
  • Sponge for wet cleaning
  • Drying towel

How to Clean Your Walls and Ceilings

Once you’ve prepared your home for cleaning and you’re wearing your protective gear, you can start removing the smoke and soot. There are four key steps to cleaning:

Step 1: Vacuum

      Start at the ceiling, then direct the vacuum’s nozzle or crevice cleaner down the walls. Make sure the end of the vacuum does not touch the surface to avoid smearing; leave about a half-inch of space to avoid contact. 

      Step 2: Wipe with a Dry Sponge

      It’s important not to use any wet products before wiping the walls with a dry sponge designed specifically for cleaning soot. Moisture at this stage would make it more difficult to remove soot.

      Apply gentle downward strokes on the walls and ceiling, being careful not to smear. The sponge will pick up soot quickly, and when that happens, you can switch to the clean side.

      Step 3: Switch to a Wet Cleaning Method

      Get as much soot off with the dry sponge as possible. If smoke stains and soot remain, use a cleaning solution of dish detergent and warm water. Some sources recommend the addition of trisodium phosphate (TSP) for heavy-duty jobs. However, if you do have severe soot and smoke damage, it’s best to contact a professional cleanup service. 

      With your cleaning solution, use a new, regular sponge or microfiber cloth to clean the remaining soot. Wring out the sponge frequently, as it will blacken from soot absorption. 

      Step 4: Rinse and Dry

        After cleaning with the sponge and detergent solution, rinse the area with clean water. Use a dampened cloth, then dry completely using a towel. 

        Fire Safety Tips for a Smoke-Free Home

        While large amounts of smoke and soot accumulation can be serious, this doesn’t mean you can never light a candle again. Practicing fire safety can prevent greater problems down the road. To maintain a safe, smoke-free environment: 

        • Trim candle wicks: Particularly with new candles, trimming the wick produces a steady flame and prevents flickering, which can lead to soot.
        • Check your fireplace: Regular fireplace maintenance helps you ensure ash is removed and the vents are clean and working properly.
        • Watch what you are cooking: A common cause of kitchen fires is leaving a stovetop or oven unattended. If you leave the room, always make sure to turn off the burner.
        • Keep your kitchen clean: Regularly wiping surfaces near the stove and cleaning your oven prevents crumbs and grease from burning. 

        When Cleaning Isn’t Enough: Signs It’s Time to Call a Professional

        While cleaning your walls and ceiling yourself may be enough to remove limited amounts of smoke and soot, the remnants of a house fire or a large accumulation of soot over time will likely require professional intervention. The following signs indicate it’s time to call your local professional restoration company. 

        • Staining returns soon after cleaning
        • Persistent odor
        • Peeling paint or damaged drywall
        • Large affected areas or ceiling damage
        • Structural and safety concerns, such as HVAC contamination

        Another reason to call a professional is if you’re uncertain or have questions about the cleaning process. If this sounds like you, skip the DIY steps and leave the cleanup to the restoration experts.
