Making a Visible Difference
The DOFF System is unique in achieving temperatures up to 150 degrees at the nozzle end making it a super heated water system. Designed and developed to effectively remove paint, biological matter and general dirt and grime without causing harm or shock to the substrate.
DOFF is a steam based stone cleaning system. unlike any other steam system and can achieve temperatures of up to 150 degrees at the nozzle end making it a superheated water system. The operator is able to vary the temperature and pressure to remove many different types of paint and biological matter.
The Doff Cleaning System in Action
We were recently commissioned to clean the Queen Victoria Statue outside the Worcestershire Combined Courts.
The statue hadn’t been cleaned for some time and it was covered in moss, algae and bird droppings. As you can see from the video and the before and after photographs below the Doff steam system cut through the dirt and matter leaving the Queen looking pristine with no damage to the stone at all.
We were really amazed at the detailed carvings in the statue which were not evident before the clean up.
What can Doff be used for?
The steam/superheated water will remove moss, algae, fungi and other biological matter and will also kill off spores. This means there is then no need to use a chemical biocide during the removal process or as a protection against further biological activity.
How does it work?
DOFF cleans stonework and masonry using high temperature steam. Whilst the temperature in the system is high, the pressure on the surface being cleaned is very gentle and the volume of water is low. The surface is therefore not saturated and will be dry within minutes.
What is Doff most effective in removing?
Paint coatings (most oil and plastic types)
Certain types of graffiti
Bird or vermin fouling
Algae, moss, and fungi
Bitumen, Oil, Grease and many others, all without causing any damage or disfiguring the substrate.
No Harmful Chemicals Are Used
As the Doff uses super-heated steam, there are no harmful chemicals used.
