What soft washing is
Soft washing uses low pressure combined with a biodegradable treatment that kills mould, algae and lichen at the root. Instead of blasting grime off with force, it lifts it gently — which is why it’s the right choice for anything painted or delicate.
Use soft washing for house cladding (weatherboard, brick, plaster, fibre-cement), roofs, eaves, soffits and fences. Because it’s low pressure, it won’t strip paint or force water in behind your cladding, and the clean lasts longer because the treatment tackles the source, not just the surface.
What waterblasting is
Waterblasting (high-pressure cleaning) uses strong force to strip away dirt. It’s the right tool for hard, solid surfaces — concrete driveways, paths, patios and pavers — where moss, oil and ground-in dirt need real power to shift.
The catch: that same force can crack tiles, gouge timber, strip paint and damage plaster if it’s used on the wrong surface. High pressure belongs on the ground, not on your house.
The simple rule
Soft wash for anything painted or up high (house, roof, fences). Waterblast for hard flat surfaces on the ground (driveways, paths, patios). A good exterior cleaner uses both — matching the method to each surface so nothing gets damaged.
