TORC Cleaning Process
For the gentle removal of Carbon Sulphation, Brittle Paints, Limescale and more
The TORC System is a complete stone cleaning system designed and sold exclusively by Stonehealth. It is an evolution of the Jos system that we first introduced to the market over 20 years ago.
How does it work?
The TORC system creates a gentle swirling vortex using a mixture of low air pressure, little water and a safe inert fine granulate.
The Torc Head is modularised into separate components which results in an efficient and gentle swirling vortex using even less water and granulate than the original Jos system.
The removable nozzle cone can easily be changed so that a larger cone can be used to clean large areas such as ashlar or a smaller nozzle cone can be used for more intricate detail such as an elaborate capital or rustications.
Different abrasive media are used in the TORC system; calcite, dolomite and unil, which is a by product of coal, allow fine-tuning of the cleaning method through varying hardness, grain shape and abrasion. By choosing the most appropriate abrasive medium to suit the substrate material, skilled use of the TORC system ensures the cleanest possible finish with the minimum possible damage to your property.
All Stonehealth approved aggregate contains less than 1% quartz with no other form of crystalline silica. It is completely safe for the environment & non-toxic.
