Heritage Stone Cleaning
DOFF

The DOFF steam cleaning system is a safe and effective way to remove organic material such as mosses, as well as carbon and paint. Being able to produce a spray of up to 150ºC at the nozzle, with a fully adjustable pressure, it helps kill the substrate and extend the length of time needed for cleaning.


It is a portable system that uses a regular water supply which then passes through a high pressure pump unit and then to the heating system and leaves the nozzle in a vortex action. Due to the temperatures it can achieve it is known as the ‘superheated water system’.

This system is best used on brick and stonework, however is capable of cleaning many types of materials such as concrete, tiled (glazed and encaustic), wood, faience and terracotta. It is a useful sterilisation tool for kitchens, toilets, swimming pools, hospitals and factories.

As the system is extremely low risk to the environment and the material being cleaned, it is one of the recognised methods of cleaning listed buildings, churches, chapels and monuments and is recommended by CADW and English Heritage.

This system is a product that is not available to hire, due to the complexity and the maintenance of the system and must only be used by a fully trained operator. It is an extremely expensive piece of equipment to purchase and is not to be mistaken with other ‘hobby’ steam cleaners and pressure washers on the market.
All our staff are fully trained to use the Doff system by Stonehealth. We are also among the short list of companies on their rosette scheme who they recommend to carry out work using their systems.

 


The DOFF system can also be used in conjunction with Paint-Rid, CleanFilm and our Torc cleaning system.
