Soft Washing or Pressure Washing? - Which Method Do You Chose?

Having the exterior of a property professionally cleaned can produce fairly dramatic results. The correct cleaning processes can remove all imperfections. Whether your property is covered in algae, environmental staining or discolouration caused by leaks. It is our goal to return the exterior of the property to its original aesthetic condition. 

 

To get the best possible results from an exterior clean, you need to select the most appropriate technique for the job. In many cases, this will be either soft washing or jet washing. Deciding which is right for your building will help you remove algae, staining and discolouration without damaging the property's façade.

 

Benefits of pressure washing

 

Pressure washing the exterior of a property is a great way to remove dirt and grime quickly and effectively. The technique uses pressurised jets of water to blast algae, mould, staining and other forms of discolouration from a surface. Once the work is complete, the façade should be clean, clear and look like new.

 

Power washing is generally used when the underlying substrate is hard and non-porous. This is because the high-pressure water can cause damage to some softer materials. Using pressure washing on a delicate surface like render, aged stone or masonry can result in an uneven finish. It can also cause long term damage to the exterior of a property and affect the aesthetic.

 

Benefits of soft washing

We can use a soft washing system to clean surfaces that would be damaged by pressure washing. Soft washing uses low-pressure water to clean surfaces and remove dirt.

Low-pressure water is not as powerful as high-pressure jets. Therefore, soft washing chemicals are often used to help loosen dirt. It will ensure a clean finish.

 

Soft washing is often used on façades that are porous or made from soft materials. Period building with stone or masonry in their exterior can benefit from soft washing. The technique won’t damage or erode stone or brick's soft surface.

 

Choosing the most appropriate method

 

Spectrum uses both power washing and soft washing on our cleaning projects. However, even for a team with extensive cleaning experience, it is not always obvious which cleaning method is the best choice. To decide between pressure washing or soft washing on UK projects, our teams test both methods. They will see the results for themselves.

 

This involves doing a sample square on the building's façade. We can determine how the surface reacts to high-pressure jets and soft washing equipment. Once the tests have been carried out, our teams are able to assess the results and choose the best method.

 

Specialist cleaning

 

In some cases, a combination of cleaning techniques is required to get the best possible results. We use a DOFF machine when soft washing is the most appropriate choice, but additional cleaning power is required. This will turbocharge the process.

 

These innovative machines allow us to offer thorough and comprehensive soft washing solutions. Unlike other systems, DOFF machines heat the low-pressure water jets to around 155˚C. This extreme heat quickly and effectively loosens and removes dirt to leave all façades stain-free and look like new. This combined approach is often used to clean surfaces such as stone and masonry that other cleaning techniques would damage.

 

This technique forms part of our patented P.A.S.T cleaning method. In the first step of this 4-stage process, our operatives prepare the area for cleaning. They then apply a specially selected biocide before using the DOFF system to remove dirt and grime. Finally, our team will apply targeted treatment to any heavy staining that dirt or grime might leave on the façade.

 

A flexible approach

 

As well as DOFF machines and specialist soft washing chemicals, our teams can use a range of innovative and patented techniques. All of which thoroughly clean the exterior of a building.

Our 4-step P.A.S.T process is incredibly effective at removing all types of staining and discolouration. Our adapted and patented equipment allows our operatives to work via ropes and from the ground. Our expertise allows us to clean the surfaces of all types of building.

 

This flexible approach means we generally require no scaffolding to be erected when cleaning a property's exterior. By avoiding the use of scaffolding, we’re able to complete the project quickly and efficiently. It will also keep access costs to a minimum.

 

When our operatives are unable to work via rope access, they can draw on a range of alternative access solutions. Our teams might opt to work from cherry pickers or adapt their equipment to carry out the clean from the ground. Using various access techniques, we can reach all areas of large commercial and residential properties.

 

Maintaining modern render

 

We carry out a wide range of cleaning and maintenance services. However, we are best known for our expertise in render cleaning. Render has a porous surface and so needs to be cleaned with soft washing in order to prevent damage. Using a DOFF machine and specialist chemicals will make the process even more effective. 

 

To help share our expertise in render cleaning, we’re running monthly CPD webinars on the subject. These will teach participants how to maintain modern render and protect the building's rendered façade from damage. If you are interested in taking part in a webinar, please contact us for more details.
