While jet washing companies are often hired for specific jobs like roof cleaning, sometimes we’re needed for larger jobs, such as historical building stonework restoration. However, getting the stone back to its former glory requires a process called DOFF cleaning.
Here’s everything you need to know about what a DOFF cleaning service involves.
What is DOFF cleaning?
DOFF cleaning is one of the most common cleaning techniques used for restoring the appearance of listed and heritage buildings.
While some forms of pressure washing involve using power jet streams to blast away grime from external surfaces, this isn’t always the most appropriate method when it comes to some hard materials. This is where DOFF cleaning comes in handy, offering a gentler form of steam cleaning ideal for restoring stonework.
High temperatures (up to 150 degrees) and different pressures are manipulated through the DOFF machine’s nozzle to remove all kinds of dirt and other substances from the stone without causing any damage. It’s a much gentler form of steam cleaning but has highly effective results without using harsh chemicals.
What does a DOFF machine remove?
Doff cleaning removes different grime and biological matter from stonework, including algae, moss and fungi. It can also remove graffiti, bird droppings, oil, grease and chewing gum.
As well as restoring stonework, it’s also chosen for cleaning concrete, brick, tiles, wood and other surfaces that require a kinder pressure washing method. The temperatures used may be high, but the pressures are relatively low, so they won’t damage the building’s façade.
Benefits of DOFF steam cleaning for stonework restoration
Much like soft washing solutions, the lower steam and water pressures of DOFF cleaning means it can be used on delicate materials, like historical stone walls and buildings. The surfaces won’t be subjected to thermal shock or abrasive methods like other cleaning techniques that may chip away at the old stone. It’s even been approved by places like English Heritage and The National Trust as a safe method of restoring older buildings.
This highly effective stone cleaning system can remove stains, discolouration and organic compounds, helping to restore properties back to their original appearance. This is thanks to the superheated steam used.
The low pressures also mean the ejected water won’t penetrate the surface deeply, ensuring materials like wood, brick and stone are dry again in no time. And, because there are no harsh chemicals used in the cleaning process, it’s better for the environment too!
