Soft Wash vs Pressure Wash
Soft wash (low pressure + biocide): Kills mould at the root, prevents quick regrowth. Lasts 2–4 years. Safe on weatherboards, painted surfaces, and roofs. Recommended for house exteriors.
High pressure: Best for concrete driveways, paths, and decks. Too aggressive for most painted or clad surfaces.
