The Potential of DOFF Cleaning for High-Rise Buildings

What is DOFF cleaning?
DOFF cleaning is an advanced, eco-friendly method for cleaning building exteriors. Unlike other methods that use harsh chemicals, the DOFF system relies solely on high-temperature steam to remove dirt, algae, and other pollutants. This helps prevent surface damage whilst still removing grime.
DOFF cleaning is particularly popular when cleaning both heritage buildings and high-rises. Heritage buildings because of the specific regulations surrounding them, and modern high-rises, due to their size (using chemicals is far more expensive than simple hot water!).
The DOFF Cleaning Process
The first step is always preparation and assessment. Before cleaning begins, the building’s material, surface condition, and contamination level should be reviewed. This ensures the correct temperature and pressure settings are used to clean, but not damage, the surface.
Once the assessment is complete, the equipment is set up, the DOFF machine is positioned, connected to a water supply, and heated to produce the high-temperature steam – very often reaching up to 150°C. Unlike pressure washers, however, (which use high pressure) DOFF systems operate at low pressure. This further helps to prevent surface erosion.
Once everything is ready, a DOFF technician will begin blasting areas of dirt, algae, paint residues, and other pollutants. As the technician works an area, the steam loosens, then lifts contaminants off the building’s surface before washing it away.
After a first clean is done, the area will be inspected to assess if further work is required.
Key Benefits of Using Hot Water Vapour Over Other Methods
As mentioned above, the main advantage of DOFF cleaning is it is entirely chemical-free and environmentally friendly. This makes it a safer and more sustainable option compared to chemical cleaning methods, which will degrade a building’s surface over time.
Suitability for Different Materials
DOFF cleaning is highly versatile and suitable for a wide range of materials, making it ideal for any building with mixed surfaces. However, it is particularly effective on stone and brick, making it popular for period properties. But it can be used on concrete, terracotta, metalwork, and glass without the risk of etching or surface damage.
Notably, DOFF steam cleaning complies with Historic England guidelines and the National Planning Policy Framework (NPPF) standards. This makes it ideal for listed buildings and other historic properties.
Ideal Applications of DOFF Cleaning
Beyond heritage and conservation work, DOFF cleaning is widely used for large-scale commercial cleaning projects, ensuring minimal disruption for high-rise offices, hotels, and residential properties. It is also effective in restoration projects following fire or smoke damage, as it cleans surfaces without introducing further chemical contamination.
Advantages Over Traditional Cleaning Methods
Compared to pressure washing and chemical treatments, DOFF cleaning offers clear advantages. It is particularly effective in preserving delicate materials, avoiding erosion and chemical staining that can occur with other solutions. The process also ensures minimal disruption, as it doesn’t require extensive setup or long drying times.
Furthermore, it allows for safer access to high-rise buildings because the system is compatible with rope access techniques. This also saves on cost as it reduces the need for expensive scaffolding setup and hire.
And if that wasn’t enough, DOFF cleaning is compliant with UK building safety and environmental standards, providing property managers and owners even more peace of mind.
Ensuring the Longevity and Cleanliness of High-Rise Buildings
For property managers and owners of high-rise buildings, DOFF steam cleaning is the optimal choice for maintaining exteriors safely, efficiently, and in an environmentally friendly manner. The process ensures that buildings remain clean, well-preserved, and compliant with conservation regulations, all while minimising disruption.
Consulting with a professional cleaning services provider is recommended to explore how DOFF cleaning can benefit your property. Maintaining a high-rise building’s integrity starts with choosing the correct cleaning method, and DOFF steam cleaning offers an effective and sustainable solution for long-term maintenance.
