Market-leading cleaning systems

Our systems have been used for large-scale projects, including Westminster Abbey, Oxford University, and the Tower of London.

Our expertise and systems are relied on by architects and building restoration companies across the UK for innovative and effective stone cleaning and masonry restoration.
We maintain an approved list of stone cleaning companies who have received our training and are using genuine systems.

DOFF Integra System

The DOFF is an expertly engineered system that utilises a normal water supply to remove some of the more resistant forms of dirt or markings from a range of surfaces.

The water supply is fed into a hot-box where it is subjected to temperatures as high as 150℃. The resultant heated water, or vapour, is then filtered through the heat resistant hoses to the nozzle at a rate of between 3 to 10 litres per minute.

Once cleaned, the surface dries within minutes to prevent any long-term damage as a result of trapped moisture.

“DOFF is an invaluable tool in our fleet of equipment, twinned with the DPU and an 800litre water tank, we are able to work remotely in town or country for many hours.”

Cleanse CRP

The TORC system is an evolution of the original Jos system, with its most distinctive feature being the revolving nozzle – creating a gentle swirling vortex to offset the concentration of the water and granulate mix.

The powder used is an inert substance that is applied with water simultaneously to achieve a ‘gentle clean’.

Its ability to effectively clean surfaces is largely due to the innovation of nozzle, rather than the granulate running through it.

Clean-Film is a latex cleaning paste that is applied to the target area and, once left for a 24-48 hour period, can be peeled off – removing all dirt in the process.

It is made up of a combination of natural latex and ammonia. Once the film is removed, the ammonia evaporates from the surface without leaving behind any residue.

There are no special arrangements that need to be made for its disposal, as it can be done at landfill sites.
