DOFF Cleaning – University of Sheffield

DOFF steam cleaning is an effective way to clean your architectural details and stonework. Being a less invasive method than sand blasting, DOFF cleaning gently cleans your facade, without damaging the face of the stone. 

As you can see this stonework was very blackened by years of environmental staining. The DOFF steam cleaning system has gently removed this revealing the architectural detail of the stonework once more, and really transforming this facade.
