What is Softwashing?

Softwashing is an effective way of removing dirt, grime, algae and other discolouration from a building’s surface. Unlike other cleaning methods, such as jetwashing, a softwash doesn’t damage modern render or cladding. Instead, it gently but thoroughly removes residue from the exterior of the property to leave the surface looking like new.

The results of a comprehensive softwash can be dramatic and long lasting. Once the exterior of a property has been cleaned and treated, algae, fungi and dirt can be kept at bay for years to come. This method of cleaning is also environmentally friendly, as it uses less water than jetwashing and has less of an impact on surrounding trees, plants and habitats.

Softwashing can be carried out from the safety of the ground or via rope access. This flexibility allows our skilled and experienced operatives to clean all areas of a building and access roofs, façades, balconies and cladding that would be impossible to reach using other methods.

What can Softwashing be used for?

This versatile and innovative cleaning solution can be used to renovate and aesthetically restore a wide variety of surfaces. Softwashing is primarily used to clean buildings that have been finished with modern render. Softwashing is the ideal cleaning method for this finish as it is powerful enough to remove stains, algae and discolouration, but gentle enough to prevent damage to the surface of the render.


Algae growth is incredibly common, and most buildings will have at least some algae growing on their exteriors. Algae is most commonly found on the north faces of buildings as this is generally the dampest and darkest part of a property.

Algae spores are carried by the wind and deposited on exterior surfaces. As they grow, these colonies become increasingly visible, turning the exterior of a building green, red or black. Softwashing is one of the most effective ways of removing algae from modern render. It can also be used to clean algae from stone, wood and tiled surfaces.


Stains can appear on the exterior of a building for a number of reasons. Leaking pipes can cause render to stain and discolour, as can persistent runoff from balconies and other metal fixings. These stains can have a significant impact on the exterior of a building and cause it to look old and tired before its time. Softwashing can remove these stains quickly and easily to leave the exterior of a property looking fresh and clean.


Buildings that are located in cities and close to busy transport links can easily be discoloured by high levels of pollution in the atmosphere. Particles from exhaust fumes and industrial activity can make the exterior of a property appear dull and dirty in a relatively short period of time. Softwashing can be used to effectively remove this dirt and grime and aesthetically renovate a property.

Which Surfaces are suitable for Softwashing?

Softwashing can be used to clean and restore many of the surfaces and materials used in modern construction. Spectrum’s innovative approach allows our operatives to restore the entire façade of a building. From balconies and window frames to walkways and roofs, softwashing can be used to transform all parts of a property.


Softwashing is the best way to clean buildings finished with render. Most types of modern render are not designed to withstand high-pressure jetwashing. This means that pressure washing can easily damage the surface of the render, leaving it with an uneven and irregular appearance.

Softwashing, on the other hand, will not damage the surface of modern render during the cleaning process. Using softwashing to clean the exterior of a building can help to restore the property to its original aesthetic condition.


Stone is commonly used to add character and visual interest to a property. Softwashing stone on a regular basis will help to keep it clear of algae and staining and ensure the exterior of the property look as good as possible.


Wooden cladding is extensively used on both commercial and domestic properties. While wooden cladding can look very attractive, it is prone to algae growth and discolouration. Softwashing can be used to effectively remove this staining and ensure the cladding is kept in good condition.


Like façades, roofs can discolour and stain over time. Softwashing is an efficient method of removing staining and organic matter from the roof. As softwashing is gentler than other cleaning methods, this algae and discolouration can be removed without any damage to your roof.

It can be tempting to just go at your brickwork with a pressure washer, but this is not advised! ❌

As jet washers exert too much pressure on the bricks, they can create cracks or erode the top layer. They also can also force more water into the brick, which later could result in the brick expand at colder times and cause further cracking.

As specialists in exterior cleaning solutions, we use steam heated up to 150 degrees Celsius to clean bricks.
