Croft is included in the Stonehealth register of trained and inducted contractors for using TORC and DOFF masonry cleaning systems.
The TORC system utilises a swirling vortex for gentle but effective cleaning, and comprises a mixture of low air pressure, a little water and a safe inert powder material. It is most effective in areas where it is inappropriate to use a lot of water and removes graffiti, paint and grime.
The DOFF system uses 'superheated water' and is ideal for removing painted finishes and can be combined with various products which soften stubborn paints. It is non-abrasive and therefore does not disturb the underlying surface.
