Doff is a highly specialised system that offers cleaning possibilities as low as 50 bars yet still outputting temperatures up to 150c.
The Doff cleaning system is suitable for sensitive surfaces that cannot tolerate the psi of a high pressure, extensive system or jet wash.
As we are a Doff Approved Contractor, our work, ethics and customer service meet the stringent requirements associated with Doff. This is something that is earned and not paid for.
In short, the answer to this is no. Carbon is a stain and requires an additional poultice along with the Doff to remove carbon, even then. Due to years of the stone absorbing the carbon, you will need chemical assistance and even media blasting to remove the carbon.
We have a reach pole that can clean 35ft safely from ground level, still maintaining up to 150c at the surface!
Brick, stone, concrete, tiled (glazed and encaustic), wood, faience, and terracotta surfaces suitable for steam cleaning using Doff.
Not only this, but our Doff steam cleaning services are a helpful sterilisation tool for kitchens, toilets, swimming pools, hospitals and factories.
