Softwashing is a highly effective and eco-friendly cleaning process that involves using a range of biocides and low pressure water to kill and remove the living biofilm of algae, mould, bacteria and other organic material that stain and discolour the exterior surfaces of buildings.

Biofilms are a combination of different algae, mould, bacteria, lichens, moss and organic matter that form when microorganisms adhere to a surface. They typically thrive in a moist environment where the porosity of the surface, its mineral composition, alkalinity and availability to retain air borne salts creates an environment favourable for them to settle, thrive and multiply.
