The benefits of DOFF steam cleaning.

When it comes to cleaning stone, brick and other materials DOFF cleaning can be extremely beneficial for both individuals and businesses. The DOFF cleaning technique refers to a steam cleaning system used specifically for brick, stone, concrete and removing graffiti. This type of steam cleaning is used on external walls and other building areas that require a intensive clean without causing any damage to the structure and substrate. Internal cleaning can be achieved via a DOFF vacuum recovery system.

In order to effectively sterilise an area and eliminate moss, fungi and other biological matter from a structure, the DOFF machine method uses pressurised heated water to cleanly remove spores and prevent future regrowth.

The pressure of the water is low (just enough to apply the amount of pressure required to remove debris) but the temperature of the water is quite high. This ensures the best results and prompt drying of the surfaces leaving the site completely free of mess and fully operational with no down time.

Why use a Doff machine for Wood?

Wood is commonly used to clad buildings and add detail to a structure. As wood is a natural material, it is prone to the growth of algae, moss and mould. It can also suffer discolouration caused by rust staining and pollution. Doff machines can remove most impurities from wood quickly and easily. This includes paint, varnish and other finishes that might have been applied to the surface of the timber.


Why use a Doff machine for stone?

Like brick, stone becomes soft and brittle over time. Using pressure washing, or other inappropriate cleaning processes to remove staining and discolouration can result in damage to the stonework. As a lot of stonework on period properties is beautifully carved, this damage can have a significant impact on the aesthetic of the façade.

The best way to protect stone during the cleaning process is to use a Doff machine. Like brick, stone responds well to cleaning at high temperatures. The 150˚C steam is able to lift virtually all types of staining and discolouration from the surface of stone, without damaging the substrate.

Doff machines are designed so that water doesn’t penetrate deeply into the surface being cleaned. This allows stone, and other materials, to dry quickly, further minimising any potential damage to the surface.
