Doff Cleaning

The DOFF Cleaning machine is a steam-based, stone cleaning and brick cleaning system. It’s completely unique and unlike any other steam-based cleaning system. It can achieve high temperatures of up to 150°C at the nozzle end, making it a ‘superheated water system’.

Due to its ‘superheat’, it is incredibly useful for removing moss, algae, fungi and other biological matter, and can also kill off spores by completely cleaning the surface it is being used on. This means there’s no need for a chemical biocide during the removal process or as a protection against further biological activity.

How Does DOFF Cleaning Work?

A DOFF machine cleans both stone 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. 

The DOFF Cleaning machine is perfect for removing all types of dirt and grime usually found on the exterior of a building, but is particularly good at tackling:

• Paint Coating
• Certain Types of Graffiti 
• Bird & Vermin Fouling 
• Algae, Moss & Fungi 
• Wax Coatings 
• Chewing Gum Oil
• Grease and Bitumen
• Other Biological Matter
