What is our approach?

Soft Washing involves the use of biodegradable chemicals to gently remove algae and other stains. 

 

Sodium Hypochlorite is the only chemical to effectively remove black algae. 

Properly mixed with a surfactant, also called a surface-active agent, this substance  (a detergent) when added to a chemical, reduces its surface tension and penetrates to kill organic matter. 

​

There are other chemicals that can be used depending on surface materials. A site survey is carried out to determine which cleaning method is most suitable. 

​

The results are stunning! And in most cases reduce the costly need to paint exterior walls.
