Soft Washing vs Pressure Washing – What’s Right for Your Home?
When it comes to cleaning the exterior of your home, it’s not a one-size-fits-all approach. The two most common cleaning methods—soft washing and pressure washing—may sound similar, but they serve very different purposes.
So, which one should you choose for your home? Let’s break it down.
What Is Soft Washing?
Soft washing is a low-pressure cleaning method that uses a combination of water, biodegradable chemicals, and surfactants to gently remove dirt, algae, mould, and mildew from delicate surfaces.
Best for:
Roof tiles (including asphalt shingles and colorsteel)
Painted weatherboards or cladding
Gutters and soffits
Wooden decks and fences
Outdoor furniture
Benefits:
Gentle on surfaces – No risk of damage to paint, sealants, or roofing materials.
Kills mould and algae at the root – The cleaning solution disinfects and prevents regrowth.
Longer-lasting clean – Because it removes spores, surfaces stay cleaner for longer.
What Is Pressure Washing?
Pressure washing, also known as power washing, uses high-pressure water spray to blast away dirt, grime, and debris from harder surfaces.
Best for:
Concrete driveways and paths
Brick or stone walls
Paved patios
Retaining walls
Garage floors
Benefits:
Highly effective at removing built-up grime
No chemicals needed (in most cases)
Fast results for hard surfaces
Caution: Pressure washing can damage softer surfaces if not done correctly. It can strip paint, crack timber, or even dent soft metals if too much pressure is used.
Why the choice matters
In New Zealand’s climate, especially in damp or coastal areas, homes are prone to mould, moss, and lichen growth. Using the wrong method could either damage your home’s exterior or fail to prevent regrowth. Soft washing is ideal for our often damp and changeable weather—it treats the cause, not just the surface.
The Bottom Line
Both soft washing and pressure washing have their place in home maintenance. The key is to use the right method for the right surface to protect your property and extend the life of your exterior materials.
