The DOFF specialist steam cleaning system is the ultimate cleaning choice for eradicating dirt and eliminating biological matter from all stonework and masonry. It removes all grime and unwanted material without the use of harmful chemicals.
How does the DOFF cleaning system work?
DOFF is a steam based stone cleaning system. It’s unlike any other steam system and can achieve temperatures of up to 150°C. Temperature and pressure can be varied according to the surface, and the system will remove many different types of paint, grime and biological matter.
A normal water supply is taken into the DOFF machine’s hot box where the water is heated to a range of temperatures from 30°C up to 150°C. The heated water is then fed through a heat resistant hose to a special nozzle at a rate of between 3 and 5 litres per minute. The special nozzle allows the jet of steam to diffuse at a very low pressure, preventing damage to the surface being cleaned.
The superheated water and steam cleans off moss, algae and other biological matter instantly. The steam also kills off any spores, preventing immediate regrowth.
What can be cleaned with the DOFF system?
The DOFF cleaning system can be used to clean ingrained surface contaminants from a great number of surfaces. These include all stone surfaces, as well as marble, plus brickwork, tiled surfaces (including roofs), metals and commercial cladding.
DOFF is the best cleaning option for heritage buildings, because it doesn’t force water droplets into the substrate. It’s also a useful sterilisation tool for toilets, kitchens, swimming pools, factories and hospitals.
DOFF is also effective in removing most oil and plastic-based paint, some graffiti, bird and vermin excrement, algae, moss, fungi, wax, chewing gum, bitumen oil and grease.
What are the benefits of the DOFF cleaning system?
- No need for chemicals.
- Steam temperature of 150°C.
- Kills biological matter and spores.
- Dries within minutes.
- Effective paint removal.
- No damage to underlying substrate – there’s no pressure, thermal shock or saturation.
Why is it especially good for masonry, stone and brickwork?
Unlike high-powered jet cleaning systems, the DOFF system doesn’t force water droplets into porous surfaces. With other high-powered jet cleaning systems water can be driven into porous surfaces. In freezing temperatures later on, this can cause spalling of brick or stonework.
