What is DOFF cleaning? - Why is a DOFF Machine so Good?

DOFF cleaning is one of the most popular cleaning services offered by Spectrum. Effective at removing a wide range of organic matter, as well as paint, staining and discolouration, DOFF cleaning helps our operatives to achieve outstanding results every time.

What is DOFF cleaning? 

Doff cleaning is a specialist cleaning process that uses a ‘DOFF’ machine. This machine super-heats water to produce high-temperature steam. This steam can then be used to clean roofs, walls, render, cladding and almost all other structural surfaces on a building. DOFF steam cleaning machines are easily portable and so can be brought to any site that requires this powerful process.

How does it work? 

Specialist DOFF cleaning machines heat water to a much higher temperature than traditional steam cleaners. This superheated steam is incredibly effective at removing a wide range of unwanted substances including algae, mould, paint and staining. The steam is delivered to the surface of the cladding, stone, masonry or render using a targeted nozzle. This helps to concentrate the power of the steam and remove staining quickly and efficiently. In fact, the steam is so effective that it negates the need for chemical solutions. This can be a real benefit when dealing with delicate materials and sensitive substrate.

What can a DOFF system be used for?

The DOFF system can be used to clean a wide range of surfaces. It is effective at removing a variety of organic substances as well as paint and graffiti. When DOFF cleaning properties in the South East, our operatives are often tasked with removing: 

·       Algae 

Algae growth is a common issue on many commercial and residential properties. Algae spores are carried through the air and deposited on external surfaces. In favourable conditions, these spores can quickly take hold, producing large areas of red, green or black discolouration. DOFF steam cleaning can quickly and efficiently remove algae from almost all surfaces to leave a façade looking like new. 

·       Graffiti 

Graffiti is a problem in lots of towns and cities across the UK. The DOFF steam cleaning system is one of the most effective ways of removing graffiti from both commercial and domestic properties. In many cases, this type of cleaning removes graffiti in a matter of moments, leaving the façade looking clean, fresh and like new. 

·       Paint 

Old, peeling paint is often removed from external surfaces before the start of a new cleaning project. Our operatives use DOFF cleaning to get rid of a wide range of water and oil-based paints, as well as varnishes and bitumastic and thermoplastic coatings. 

Cleaning at height. 

In cases where Spectrum is asked to clean high-rise buildings and large commercial structures, our operatives are able to increase the reach of DOFF cleaning using our patented equipment. This innovative approach gives our expert team the reach they need to access all corners of a building and leave the exterior looking like new.

The benefits of DOFF cleaning.

The DOFF cleaning system offers a number of benefits over other options. While it is not suitable for all situations and all surfaces, it is ideal for a wide variety of applications. 

- Protecting the underlying structure.

One of the major benefits of DOFF cleaning is that it does not damage the underlying substrate. Other high-pressure cleaning methods, like jet washing, can easily damage soft stone or masonry, resulting in a pitted, uneven appearance at the end of the cleaning process. 

As DOFF cleaning uses low pressure, high temperature steam, there is no chance of inadvertently damaging the underlying materials. The method is so safe and so effective that it is the only system accredited by English Heritage for use on their protected buildings. 

Spectrum often uses this system to clean period properties. These buildings, like many managed by English Heritage, have antique façades and are made of delicate materials. DOFF cleaning London period properties allows our teams to restore these beautiful buildings to their former glory. 

- No need for chemicals. 

The superheated steam produced by DOFF machines is so effective it can remove a wide range of stains and discolouration without the need for chemical cleaning products. 

- Quick and efficient.

 Completing cleaning projects quickly and efficiently allows Spectrum to keep costs down and minimise disruption. As DOFF cleaning gets rid of a wide variety of staining, paint, organic matter and discolouration in moments, the system allows our teams to work as fast as possible. 

- Easy access

 DOFF cleaning machines are readily mobile, allowing our operatives to use the system wherever necessary. In cases where the staining or discolouration is located high up on a building’s façade, Spectrum can use a variety of specialist access techniques to reach the affected area and resolve the issue. 

What facades can be cleaned with DOFF?

DOFF cleaning services are very versatile. The system can be used to clean everything from stone and brick to wood and tile. Our experienced operatives are able to advise clients as to whether DOFF cleaning is the best option for their needs. They will also be able to talk them through the cleaning process and what they can expect from the finished result.
