Doff Cleaning

The DOFF steam cleaning system is ideal for cleaning stonework, masonry, and K-Rend surfaces with its high-temperature steam. Its ability to generate intense heat allows for a reduction in water pressure, making it a gentle and non-abrasive cleaning method unlike pressure washing. Besides being environmentally friendly by minimizing water usage, the system ensures quick surface drying within minutes. Moreover, the DOFF system prevents moisture from seeping into cracks or gaps, eliminating the risk of internal dampness and potential structural damage.

In addition to being environmentally friendly and safe, the DOFF system effectively eliminates spores during the cleaning process without relying on harsh chemicals. Its use not only promotes a cleaner environment but also serves as a preventive measure against future biological growth.

Deep Cleaning

Dirt, moss and algae can give stone and brickwork a faded look. The stonework can be brought back to its former glory using the cleaner (before and after pictures above). Doff cleaner can clean the following surfaces among many others:

Stone
K-rend
Brick
Wood
Building restoration

Doff steam cleaner can clean away:

Bitumen
Grease and oil
Some forms of graffiti
Chewing gum
Bird and vermin fouling
Paints
Fungi, moss and algae
General dirt and grime

Will the surface get damaged during cleaning?

No, when used correctly, DOFF cleaning solely relies on steam and water, minimizing the risk of harming solid surfaces such as masonry, concrete, or brickwork. This method is entirely devoid of chemicals, ensuring the safety of historic structures or more delicate materials.

What surfaces can DOFF be used on?

The DOFF system is highly effective in cleaning sturdy materials like stone, brick, and concrete. However, it can also be utilized on delicate surfaces such as wood, terracotta, and faience without causing any damage.

Where can DOFF be used?

In addition to its popularity for outdoor cleaning purposes, it serves as a highly beneficial tool for various applications including building restoration, food production environments, and hygiene control. Indoor environments such as swimming pools, kitchens, toilets, and hospitals can be effectively sterilized with its usage. Moreover, its industrial strength makes it perfect for cleaning high-traffic and heavily polluted facilities like factories, workshops, garages, and vehicle depots.

What can DOFF be used for and How does it work?

The Doff steam cleaning method is highly secure and won’t cause any harm to the surface being cleaned. By using superheated water, it effectively eliminates moss, algae, fungi, and other biological substances, while also eradicating spores. This implies that there is no necessity to apply chemical biocides for removal or subsequent protection against further biological activities. One major advantage of utilizing superheated steam for your building cleaning project is that it doesn’t involve harsh pressure or chemicals, ensuring there is no risk of damage. English Heritage exclusively supports the Doff steam cleaner for use on its buildings, and this endorsement is well-founded.
