DOFF CLEANING

The DOFF System

The DOFF system complements the JOS system and is the natural answer to the removal of surface coatings such as bitumen, oil, grease and other disfiguring materials. Here you can see brick cleaning underway. A unique combination of heat and pressure is used to cut through and remove unwanted matter without eroding the underlying surface.

DOFF cleans stonework and masonry using high temperature steam. Whilst the temperature in the system is high, the pressure on the surface being cleaned is very gentle and the volume of water is low. The surface is therefore not saturated and will be dry within minutes.
