How to clean soot off walls

To clean soot off walls, always dry clean first. Then do the following:

Vacuum loose soot with a HEPA filter
Lift the residue with a dry chemical sponge before any wet cleaning

Soot is oily and acidic, so attempting to clean it with water first will smear it deeper into the surface and may stain the wall permanently. If you are dealing with anything other than light marking, professional cleaning is always the safer option. Here’s why and what the process involves:

If you do attempt to clean light soot marks yourself:

Ventilate the property and protect yourself: Soot particles are harmful to breathe, so wear a mask and gloves. Keep the room ventilated throughout.
Dry-clean before anything wet: Vacuum loose soot using a HEPA-filter vacuum, holding the nozzle just off the surface so you don’t smear particles into the wall. Then use a dry chemical sponge, in light, single-direction strokes, never scrubbing.
Consider wet cleaning: If marks remain on the walls, a degreaser may help remove them, but test this on a hidden area first, as soot residue and some cleaning materials can lift paint.
Work from top to bottom: Clean from the ceiling down so any loose particles fall onto surfaces you haven’t cleaned yet.
Know when to stop: If the soot smears, spreads or reappears, stop cleaning. Continuing could lead to further damage.

We explore this process in more detail in our guide on how you can try cleaning soot off walls.

Why DIY cleaning isn’t enough

DIY attempts at soot and ash removal may work for very light, superficial marks, but soot from a fire is acidic and embeds into paint, plaster and porous surfaces. Furthermore, it has health risks that you would much rather avoid.

Improper cleaning can spread contamination, drive soot deeper and cause etching and staining on the affected surfaces. This is why most soot damage needs professional cleaning.

Our technicians use HEPA-filtered equipment, specialist chemical sponges and alkaline neutralising agents to remove soot safely and completely, protecting your surfaces and your health.

How to clean soot off brick

Cleaning soot off brick is harder than cleaning it from a painted wall. This is because brick is porous and absorbs soot deeply. As with walls, brush or vacuum loose soot away before applying anything wet.

For light soot on brickwork, try the following if you feel comfortable doing so:

Dry-brush first: Use a stiff (non-wire) brush to remove loose soot, brushing away from the clean areas. Vacuum up the residue with a HEPA filter.
Don’t wet it yet: Never start with water. This will drive the soot deep into the pores, causing lasting discolouration.
Use a degreaser for deeper marks: Because brick is porous, you’ll need a specialist masonry degreaser rather than just general surface wiping. Results will vary, and this is not guaranteed to remove heavy staining.
Don’t seal over soot: Applying a sealant or paint over the uncleaned brick traps the residue and the smell. Over time, the stain will bleed back through.

Brick's porous nature is why DIY cleaning often falls short. For fire-damaged or heavily stained brickwork, professional soot removal is usually the only way to restore it properly.

Depending on the surface, we use techniques including specialist chemical cleaning and, for stubborn masonry staining, controlled methods such as sandblasting, an approach we used in our Bromley case study. Find out more about our specialist brick and stone cleaning services across the country.

Why you need professional ash and soot cleaning services rather than DIY

After a fire, acidic soot and ash residues can linger on surfaces, posing health risks and causing ongoing damage if not removed quickly and correctly. Professional soot and ash cleaning targets these harmful particles at their source, protecting your property, improving air quality and preventing long-term deterioration.

Immediate protection against corrosive residues: Soot and ash contain acidic compounds that can etch glass, corrode metal fixtures and degrade porous materials over time. Professional cleaning stops these corrosive effects before they worsen.
Enhanced health and safety: Fine soot particles can become airborne and irritate lungs, eyes and skin. Specialist removal with HEPA filtration and advanced techniques improves indoor air quality and reduces respiratory risks.
Thorough, surface-by-surface cleaning: BDMA-accredited technicians use proven methods like HEPA vacuuming and specialist chemical cleaning to remove residues from walls, ceilings, fixtures, and fabrics, beyond what ordinary cleaning can achieve.
Prevention of secondary damage: By eliminating ash and soot promptly, professional cleanup helps prevent further staining, odour absorption and difficult-to-reverse material degradation, saving time and repair costs later.
Tailored solutions for every property: Whether it’s a small domestic space or a large commercial building, experts customise soot and ash cleaning plans to suit the unique condition and contamination level of each site.
Insurance-ready reporting and compliance: Professional restoration teams document their work clearly, providing evidence and reports that support fire damage insurance claims and demonstrate adherence to industry standards.

Soot & ash cleaning FAQs: Your questions answered by experts

How do you remove ash and soot after a fire?

We use a precise combination of specialised techniques to safely and effectively remove ash and soot. This typically includes advanced HEPA vacuuming to capture microscopic particles, specialist chemical sponges for delicate surfaces, and a range of alkaline-based cleaning solutions to neutralise corrosive residues. Our team always wears full Personal Protective Equipment (PPE) to ensure safety during the entire removal process.

Can ash and soot be harmful to my health?

Yes, prolonged exposure to ash and soot can be harmful. These toxic particles can irritate your lungs, skin, and eyes. If you have existing respiratory conditions like asthma, inhaling fine soot particles can significantly worsen your symptoms and increase the risk of long-term health issues. Professional soot and ash cleaning is crucial for your well-being.

How much does a professional soot cleaning service cost in the UK?

The cost of specialist soot cleaning services in the UK varies depending on the extent of the affected area and the severity of the damage. For a company offering comprehensive, high-quality service, you can typically expect charges to range between £1,000 and £1,500 per day. We provide a detailed, transparent quote after assessment which is based on photos of the damage or, in worse cases, a site visit.

Are you able to permanently remove the smell of smoke too?

Yes, absolutely! While our primary focus here is soot and ash removal, we can certainly eliminate lingering smoke odours. We use BIOSWEEP® technology, one of the most effective treatments for completely removing smoke smells after a fire. In fact, we guarantee 100% odour removal with this advanced system.

We understand the urgency of soot and ash removal. As soon as payment for the work is confirmed, our team will promptly schedule your service for a date that suits you best. We can often offer appointments for the very next day, or at the very least, within one week, ensuring a rapid response..

How long does it take to clean a property affected by soot and ash?

Smaller areas or light contamination might be completed in a single day, while extensive fire damage across a larger property could take several days or even weeks. During our initial on-site assessment, we’ll provide a clear, estimated timeline tailored to your specific situation.

Can I clean soot and ash myself?

While small, superficial marks might seem manageable, we strongly advise against attempting to clean soot and ash yourself. Soot particles are highly acidic and abrasive; improper cleaning can spread contamination, embed the soot deeper into surfaces, and cause permanent damage. More importantly, it poses significant respiratory and skin health risks. Professional soot and ash cleaning by certified experts ensures safe, complete, and effective restoration.

What happens if soot and ash are not cleaned properly?

If soot and ash are not properly removed, they can lead to severe long-term problems for your property and health. Beyond persistent unpleasant odours, soot causes irreversible etching and discolouration on surfaces like walls, metals, and plastics. Its corrosive nature can also damage electrical components and HVAC systems. From a health perspective, microscopic soot particles can cause ongoing respiratory issues, especially for vulnerable people such as the elderly and children.
