Fire Soot

Fire soot contamination can be widespread and intrusive, affecting structural materials, finishes, contents, and equipment. Effective cleaning must remove soot and smoke residues while controlling odors and protecting the underlying substrates.

Common methods

• Dry ice blasting: Removes soot, char, and smoke residues from structural wood, concrete, masonry, and some metals without adding water, ideal for framing and hard surfaces.

• Soda blasting: Cleans fire-damaged surfaces and helps neutralize smoke odors on wood, masonry, and metal while being less aggressive than traditional abrasives.

• Dry vapour steam cleaning: Treats soot and smoke films on hard surfaces, tile, and selected finishes using high-temperature, low-moisture steam.

• Chemical cleaning: Uses fire restoration cleaners and deodorizing agents to dissolve residues and address odours on surfaces and contents.

• HEPA vacuuming and detail cleaning: Captures loose soot, ash, and fine particulates from surfaces, cavities, and fixtures.

• Sponge and abrasive blasting (where appropriate): Remove heavier fire damage and coatings from concrete, brick, and steel prior to restoration and recoating.

Typical applications

• Structural cleaning of framing, block walls, and concrete after fire events.

• Removing soot and smoke residues from walls, ceilings, and building finishes.

• Cleaning mechanical, electrical, and process equipment impacted by soot (following manufacturer and safety guidance).

• Deodorizing and cleaning interiors and contents in commercial and industrial buildings.

• Preparing affected areas for sealing, repainting, and reconstruction as part of full fire restoration projects.
