Why this matters for Melbourne properties
This Pressure Cleaning article is written for Melbourne owners and managers who need more than a quick blast. Render Cleaning jobs in our city require a surface diagnosis before any cleaning starts.
In Melbourne, everything from growth corridor new-build mortar smear to inner-suburb heritage brick has its own cleaning risk profile. The right method, chemistry and pressure keep the surface safe and the result lasting.

Acrylic paint on render flakes when hit with full pressure. Soft wash uses chemistry to do the work.
Soft wash is below 500 PSI
A genuine soft wash uses detergent dwell + low-pressure rinse — typically 300–500 PSI.
Mix rates matter for biocide
Sodium hypochlorite mix rate determines whether mould kills or just bleaches surface.
