JOS / TORC
The patented JOS cleaning process gives a new dimension in cleaning technology doing no harm to the environment because it is chemical free.
- Low pressure
- Rotational vortex
- Cleaning of facades
- Chemical free
- Works gently and effectively
For the safe removal of carbon pollutants from: Stone,brick,terracotta,ceramic tiles,glass,concrete & many other materials. Also oxidation/Sulphuration products from Bronze, Brass, Copper, Anodised Aluminium etc. A mixture of low air pressure, very little water (1.5 to 10 gallons per hour ) and a fine inert safe abrasive powder is developed into a rotating vortex. When directed onto a surface to be cleaned, this swirling vortex gently, yet effectively removes unwanted matter such as carbon, stubborn dirts, scale, graffiti and certain kinds of paints, from many types of materials including stone, brick, metals – even wood and plaster. JOS is unique in it’s efficiency and gentleness in cleaning as the substrates surface is left undamaged.
There is a JOS Nozzle for all tasks. For most surfaces the JOS standard nozzle will quickly and efficiently clean. For more detailed work there is the micro nozzle. For very fine, intricate and delicate objects, the conservator can produce some remarkable cleaning results with the JOS Piccolo Nozzle. Whichever JOS Nozzle is used, JOS works in a totally different way and produces a far superior result than any other cleaning system.
Many fine and important buildings have been cleaned by the JOS/TORC system including: Albert Memorial London, Entire bronze cleaning at Buckingham Palace (Kitchen block), Henry V11’s Chapel at Westminster Abbey, Lincoln Cathedral, St James Palace – London, Salisbury Cathedral, Stafford Library, Canterbury Cathedral, Harrods, Oxford Colleges, Empire Hotel Bath Royal Mews, and Windsor Castle.

TORC cleaning system
Primarily a new design nozzle that we in the UK call ‘TORC’ , possessing the same swirling vortex characteristics it inherits from the supplier of JOS. The new nozzle is supplied in the basic sizes ‘TOC’ and TORC studio’. The Torc has a removable nose section allowing a choice of 5,7,9,11 or 13mm apertures, while the studio has 1, 2, 3, or 4 apertures. The swirling actions developed by replacement ‘Stator’ housed within the nozzle itself. The Stator also develops a more ‘exaggerated’ action demanding less water to ‘lubricate’ the process of swirling. This has a number of benefits; A reported lower consumption of granulate to produce a given rate of work; The ability to work drier, or even dry if necessary while still maintaining the swirling action ( though water always enhances efficiency and the natural appearance of the clean ).
Is it the gentlest system available?
Is it cost effective?
Of all the new method of cleaning technology now available, JOS/TORC has proved to be very cost effective and compares favourably with the cost of more traditional and damaging methods of cleaning particularly when considering how gently it works.

The new method of cleaning using steam in a unique way, chemical free.
- Oil & Grease
- Chewing Gum
- And many other problems solved without damage
How the DOFF works:
A normal water supply is taken into the high pressure pump where the pressure is increased to a required level before it enters the hot box where the temperature is increased to up to 150 degrees Celsius if necessary. This is then fed through the high pressure heat resistant hoses to the nozzle.
