What Is DOFF Cleaning?

The unique DOFF cleaning machine superheats water in order to produce a high-temperature steam (up to 150ºc at the nozzle end) at low pressure. This enables our team of specialist operators to clean stone and brickwork without excess water, which can flood the area. Pressure and temperature can both be adjusted, depending on the type of matter being removed.

Whilst the DOFF cleaning system may resemble a standard pressure washer system, the actual cleaning process used is much different. A much lower and gentler volume of water is used to achieve impressive results, meaning that surfaces dry out much quicker than they would following pressure washer cleaning and less water is used. As the superheated water vapour removes stubborn matter and kills off damaging moss and fungi spores, there is no need to use a further chemical cleaning solution.

What types of buildings can DOFF cleaning be used on?

DOFF cleaning is now the preferred method of cleaning for building contractors and architects. It is important to use the specific DOFF cleaning process in order to protect buildings - the high temperatures and gentle pressure used removes mould, graffiti and discolouration and leaves stone or brickwork looking like new without any risk of damage to the building surface and without the use of harsh chemicals.

The DOFF cleaning system also allows us to work in remote locations and areas, without access to water or power, as we can supply these ourselves.
