The DOFF is a professional cleaning system that utilises low pressure and water volume with high temperatures to safely clean sensitive surfaces. It is an essential tool for brick and stone cleaning , especially for heritage properties.
We all want our buildings to look their best, but there’s a catch that many property owners learn the hard way: the very thing you do to “fix” a dirty exterior can often be the thing that breaks it. While it’s easy to spot the damage caused by pollution, moss, or weather, the damage caused by a well-intentioned but overly aggressive cleaning crew is much harder to undo.
Protecting your building isn’t just about fighting off the elements; it’s about protecting it from the cleaning process itself. If you use too much pressure or the wrong chemicals, you risk “blowing” the face of your bricks or permanently scarring delicate stonework. To get a deep clean without the collateral damage, you need a method that respects the age and material of your property. That’s exactly why the DOFF cleaning system has become the gold standard for restoration.

FAQs
DOFF cleaning is a specialised steam-based cleaning method designed for the sensitive restoration of building exteriors.
Unlike traditional “pressure washing,” which relies on high-velocity water to strip away dirt (often taking the face of the brick with it), the DOFF cleaning system uses temperature as its primary cleaning agent. By heating water to 150°C, the system creates a “superheated” vapour. When this steam hits the surface, it instantly liquefies grease, paint, and organic matter without the need for abrasive force or harsh chemicals.
The brilliance of the DOFF system lies in its ability to remain “gentle but firm.” Because the volume of water is kept low, the substrate does not become saturated. This is critical for older buildings, as it prevents water from being trapped behind the surface, which causes damp or “freeze-thaw” damage during winter months.
Furthermore, because the steam is delivered at such high temperatures, it provides a level of sterilisation that cold-water systems simply cannot match. It doesn’t just wash away algae; it kills the spores, significantly delaying regrowth.
Graffiti on a commercial property or a historic home is a nightmare for owners. The challenge isn’t just removing the paint; it’s doing so without leaving a “ghost” image or a permanent scar on the masonry.
Using the DOFF system for graffiti removal is the most effective solution available. The heat breaks down the chemical bonds of the aerosol paint, allowing it to be lifted out of the pores of the stone. This ensures a uniform finish that restores the wall to its original state, protecting the aesthetic value of your property.
A building’s facade is constantly under attack from carbon pollutants, bird guano, and biological staining. For modern finishes like K-Rend or traditional London stock brick, facade cleaning must be handled with precision.
The DOFF system is the preferred choice for architects and heritage bodies (including English Heritage) because it cleans without changing the “character” of the stone. It removes years of industrial grime and “black crust” while leaving the delicate patina of the building intact.
Whether you are managing a retail park, an office block, or a residential estate, external building cleaning is a vital part of preventative maintenance. Accumulated dirt isn’t just an eyesore; it can hide structural cracks and accelerate the decay of mortar joints.
By employing DOFF expertise, property managers can ensure their assets remain in peak condition. The system’s versatility allows it to move from cleaning heavy bitumen and oil on a loading bay to delicate moss removal on a roof, all with a simple adjustment of the controls.
A tool is only as good as its operator. At Ideal Response, our technicians are highly trained in the nuances of the DOFF cleaning system. We don’t believe in a one-size-fits-all approach; we assess the substrate, the type of contaminant, and the surrounding environment to deliver a bespoke cleaning plan.
