The TORC system, also commonly referred to as JOS cleaning, creates a gentle swirling vortex that combines low air pressure, a small amount of water, and a safe fine granulate. By carefully adjusting the air and water pressures, our technicians can tailor the cleaning process to suit different surfaces and conditions.
This method is recognised as one of the most controlled and sympathetic ways to clean masonry and stone surfaces. Alongside DOFF cleaning, the TORC system provides exceptional precision, allowing specialists to remove surface contamination while preserving the integrity of delicate materials.
The design of the TORC system enables it to clean large areas across a wide variety of surfaces while remaining gentle enough for intricate architectural features that could be damaged by traditional abrasive cleaning methods.
Conventional cleaning methods can often harm delicate masonry and decorative stonework. However, the adjustable settings of the TORC/JOS system allow for safe and effective cleaning, even on the most sensitive surfaces commonly found on historic or listed buildings.
Typical applications for TORC façade cleaning include removing heavy carbon deposits from brick and stone, particularly on buildings exposed to long term urban pollution. The system is also highly effective at removing graffiti, paint, biological growth, and limescale, and can remove lime washes in many cases.
The cleaning process can be finely tuned by adjusting the water content, granulate quantity and pressure levels. This flexibility allows the TORC system, often used alongside DOFF cleaning, to deliver the best possible results across different materials, façade types and environmental conditions.
