DOFF steam cleaning uses very high temperatures and extremely low pressure, allowing delicate, historic and porous surfaces to be cleaned safely using heat rather than force.
Traditional pressure washing relies on high water pressure, which can force water into surfaces, erode materials and cause damage — particularly to older brickwork, stone, render and lime mortar.
For a full breakdown of the differences, including where each method is appropriate, see our guide:
