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’s then no need to use a chemical biocide during the removal process or as a protection against further biological activity. We have used the process to clean stone, concrete and brickwork
HOW DOES DOFF CLEANING WORK?
DOFF cleans stonework and masonry using high-temperature steam, up to 150 C. 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.
WITH ABSOLUTELY NO SURFACE DAMAGE.
We recommend the DOFF for use on surfaces such as brick, stone, concrete, tiled (glazed and encaustic), wood, faience and terracotta. It is a useful sterilisation tool for kitchens, toilets, swimming pools, hospitals and factories.
As the Doff uses super-heated steam, there are no harmful chemicals being used. After being used outdoors, the debris needs to be separated from the water and disposed of in accordance to local regulations. The water, however, will simply run into the ground to be absorbed back into the earth.
