At Softwashing UK, we have successfully used the Doff Steam cleaning system to restore and clean hundreds of buildings and monuments across the UK. Known for its exceptional results, Doff Steam cleaning is the benchmark for stone substrate cleaning and restoration. Used to maintain some of the UK’s most historic buildings, Doff is the ideal solution for delicate and tough cleaning tasks alike. Highly recommended for many restoration projects, Doff uses high temperatures that often eliminate the need for chemical treatments, providing an eco-friendly and effective solution.
The Doff Steam cleaning system heats water to temperatures of up to 150 degrees Celsius. At these high temperatures, it effectively eradicates organic growths such as moss, algae, lichen, and fungi. Doff can also remove paint and graffiti, eliminating the need for harsh chemical cleaners in many cases. The high heat targets and kills organic growth at its root system, ensuring more thorough and lasting results.
Unlike traditional pressure washing that relies on high pressure to force contamination off surfaces, Doff uses steam generated at 150°C. This method uses heat rather than raw power to clean. The steam is discharged at low pressure, in small amounts, allowing surfaces to dry quickly. This combination of heat and low pressure reduces the risk of damage and often eliminates the need for chemical cleaning treatments, making it a gentler and more eco-friendly option for restoration.
Doff is incredibly versatile and can be used on a wide variety of substrates. It is ideal for stone, ceramic tiles, concrete, and wood, making it a great choice for both outdoor and indoor cleaning. Doff is particularly effective for cleaning and restoring render surfaces, though it is always advisable to consult with us before using Doff on certain render types to ensure it is suitable.
One of the main benefits of Doff Steam cleaning is its eco-friendly nature. Since no chemicals are used, there is no need to collect or segregate run-off water. The steam-based system is safe to allow to flow back into the environment, making it a highly sustainable cleaning method. In addition, Doff is energy and water-efficient, using minimal resources while delivering powerful results.

Stone, brick, render, and other delicate surfaces on commercial buildings can become tarnished by pollution, algae, moss, graffiti, paint, and general weathering. Cleaning these materials requires care — especially for heritage sites or fragile façades. That’s where Softwashing UK comes in.
We provide professional DOFF steam cleaning — a highly effective, low-impact method using superheated water to remove grime, biological growth, and coatings without damage.
1. Gentle Yet Powerful Cleaning with DOFF Technology
The DOFF system uses high-temperature steam (up to 150°C) at low pressure, making it ideal for sensitive materials. It removes dirt, paint, and organic growth without harming the substrate, making it perfect for heritage and listed buildings.
2. No Chemicals Required
Unlike other methods, DOFF cleaning often requires no chemical use. The intense heat alone kills moss, algae, and fungi spores, offering a natural and eco-conscious solution for building restoration and maintenance.
3. Effective on a Wide Range of Stains & Substances
DOFF is ideal for removing graffiti, oil stains, chewing gum, bitumen, bird fouling, paint, biological growth, and general soiling — even from intricate or porous surfaces like stone carvings and decorative brickwork.
4. Preserves Building Fabric & Heritage Value
Because it uses steam rather than high pressure or harsh chemicals, DOFF cleaning prevents damage to mortar joints, stonework, render, and brick. It’s widely approved by heritage and conservation authorities.
5. Trained & Certified Technicians
Our team is fully trained in DOFF operation, surface sensitivity, and conservation best practices. We’re experienced with both modern and historic commercial properties — from office blocks to churches and period architecture.
6. Environmentally Friendly & Minimal Run-Off
With little water usage and no need for chemical agents, DOFF is a sustainable choice. Run-off is minimal and safe, making it ideal for urban areas, schools, retail spaces, and environmentally sensitive zones.
7. Flexible Scheduling with Minimal Disruption
We plan our work around your operational hours — early mornings, evenings, or weekends — to ensure minimal interference with staff, tenants, or customers. Cleanliness without compromise.
8. Restore Your Building’s Original Character
DOFF cleaning restores masonry, render, and natural stone to their original appearance — brightening your building façade, enhancing curb appeal, and reflecting positively on your business.
We provide professional concrete cleaning using our advanced soft wash technology — a safe, effective, and long-lasting alternative to high-pressure washing.
1. Safe, Non-Damaging Soft Wash Technology
High-pressure jets can etch or weaken concrete over time. Our low-pressure softwash system, combined with powerful biodegradable agents, removes deep-set grime without damaging the surface.
2. Remove Oil, Algae, Moss, and Surface Contaminants
We treat the surface with specialist biocides and degreasers to lift stubborn stains, organic growth, and industrial grime. This includes moss, algae, lichen, oil patches, tyre marks, and environmental pollution.
3. Improve Safety with Slip-Prevention Cleaning
Algae and moss on concrete walkways or loading zones pose a serious slip hazard, especially when wet. Our cleaning removes these risks and helps maintain compliance with health & safety standards.
4. Extend the Life of Your Concrete Surfaces
Contaminant buildup can accelerate wear and surface erosion. Regular softwash cleaning protects and preserves your concrete, reducing repair costs and extending usable life.
5. Fully Trained & Insured Commercial Technicians
Our team is highly trained in softwash systems, surface care, and commercial site safety. We’re fully insured and experienced in working across sectors including retail, logistics, education, and healthcare.
6. Eco-Friendly Cleaning Solutions
Our cleaning agents are biodegradable, pH-neutral, and environmentally safe. They’re suitable for use around people, landscaping, and drainage systems — no toxic runoff, no disruption.
7. Minimal Disruption to Your Operations
We offer flexible scheduling to suit your business, including early mornings, weekends, or planned shutdown periods. Our efficient, quiet methods ensure minimal impact on daily operations.
8. Restore a Clean, Professional Look
A clean concrete surface enhances your property’s image, reinforces professionalism, and creates a welcoming environment for clients, staff, and visitors.
