DOFF Cleaning at Fulwell Windmill

DOFF Cleaning at Fulwell Windmill

Works have started cleaning algae and weathered Lime Wash from the External faces of the Windmill with our DOFF machine utilising the Water Retrieval System.

 The DOFF machine is a steam-based stone cleaning system that relies on superheated water rather than chemical biocides to clean materials from stone and brick to wood and terracotta. As well as removing algae, the system can be used on most paints, bird fouling, and oils and grease.
