DOFF Steam Cleaning

DOFF Steam Cleaning

An expertly engineered system that uses steam or superheated water

DOFF is an expertly engineered system that uses steam or superheated water to remove more stubborn forms of dirt or markings from stonework and masonry, from moss and algae to bitumen and paint.

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

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

We can send our operatives nationwide and always guarantee 100% customer satisfaction, which is backed up by our recommendations.
