How to Clean Smoke Damage From a Brick Fireplace?
Last updated October 26, 2026
The short answer
Start with Dry Cleaning
Begin by protecting the surrounding area with drop cloths and wearing gloves and a dust mask. Use a stiff-bristled brush to loosen dry soot from the brick surface, working from the top down to avoid streaks. Vacuum up the loose debris with a shop vacuum fitted with a HEPA filter to trap fine particles.
Avoid using water at this stage, as wet soot can smear and drive deeper into the porous brick. If the fireplace has heavy buildup, repeat the dry brushing until most of the visible soot is gone. This step makes the wet cleaning more effective and reduces the risk of spreading stains.
Choose the Right Cleaner
For light smoke residue, a simple solution of dish soap and warm water often works well. For tougher stains, look for a cleaner made specifically for brick or masonry, which can break down oily soot without damaging the surface. Always test any cleaner on a small, hidden area first to check for color change or etching.
Avoid harsh acids or bleach, as they can discolor brick and mortar. If the smoke damage is extensive or the brick is old and fragile, a professional assessment may be safer. The pros can identify the right cleaning method and protect the fireplace structure.
- Dry brush and vacuum first
- Test cleaner on a hidden spot
- Use masonry-safe products only
- Avoid bleach and acid cleaners
- Rinse thoroughly after cleaning
- Let the brick dry completely
Wet Cleaning Steps
Mix your chosen cleaner according to the label instructions and apply it to the brick with a sponge or brush. Work in small sections, scrubbing gently in a circular motion to lift the soot. Rinse each section with clean water before moving on, so the residue does not dry back into the pores.
For deep-set stains, you may need to repeat the process several times. A paste of baking soda and water can help lift stubborn marks without harsh chemicals. After the final rinse, use a clean cloth to blot excess moisture and allow the brick to air dry for at least a day.
Handle Lingering Odors
Smoke odor can persist even after the brick looks clean. Place bowls of white vinegar or activated charcoal near the fireplace to absorb smells over several days. Baking soda sprinkled on the brick and left overnight can also help neutralize odor, then vacuum it up the next morning.
If the odor remains strong, the smoke may have penetrated deeper into the masonry or the surrounding walls. In that case, you might need professional odor removal equipment that reaches into porous surfaces. The pros can also check for hidden soot in the chimney or flue.
Know When to Call the Pros
Smoke damage can be tricky, especially if the fire was large or the fireplace has not been cleaned in years. If dry and wet cleaning does not remove the stains or the odor lingers, it may be time to bring in local water damage pros. They have the tools and experience to handle heavy soot and smoke residue safely.
In humid climates like Daytona Beach, leftover moisture can worsen smoke damage and lead to mold growth. If you notice a musty smell or see any water stains near the fireplace, a professional inspection can help. They can also document the damage for your insurance claim if needed. Policies vary, and your insurer decides what is covered.

Can I use bleach to clean smoke off brick?
Bleach is not recommended for brick because it can discolor the surface and damage the mortar. Instead, use a mild detergent or a cleaner made for masonry. Test any product on a small area first, and rinse thoroughly to avoid residue.
How long does it take for brick to dry after cleaning?
Brick is porous and can take 24 to 48 hours to dry fully, depending on humidity and airflow. In a humid area like Daytona Beach, drying may take longer. Use fans or open windows to speed up the process, and wait until the brick is completely dry before using the fireplace.
Will smoke damage come back after cleaning?
If soot and odor are not fully removed, they can reappear, especially when the fireplace heats up. Proper cleaning and thorough rinsing help prevent this. If the problem persists, a professional cleaning may be needed to reach deeper layers of the brick.
