Soft Wash vs. Water Blasting in Tauranga: What’s Best for Your Property?
If you’re a Tauranga homeowner, you’ve probably heard the terms soft washing and water blasting thrown around when it comes to exterior cleaning. But what’s the difference? And more importantly — which one should you choose for your property?
Whether you’re removing mould from your house, cleaning your driveway, or preparing for a repaint, choosing the right cleaning method is essential for achieving great results without damaging your surfaces.
In this guide, we’ll break down the pros and cons of each approach, explain which surfaces are best suited to soft washing vs water blasting, and help you avoid common (and costly) mistakes.
What Is Soft Washing?
Soft washing is a low-pressure cleaning method that uses eco-friendly chemical solutions to remove dirt, grime, algae, and mould.
Rather than blasting away growth with force, soft washing uses detergents to kill and lift contaminants, followed by a gentle rinse.
Key Benefits:
- Safe for delicate surfaces
- Kills organic growth at the root
- Longer-lasting results than pressure alone
- Uses less water
- No surface damage or paint stripping
Ideal For:
- Painted weatherboards
- Timber cladding
- Plaster and stucco
- Colorsteel walls and trims
- Soffits and eaves
- Roof treatments
- Windows and window frames
What Is Water Blasting?
Water blasting, also known as pressure washing, uses a high-powered water jet to forcefully remove grime, stains, moss, and dirt from surfaces.
This method is highly effective for hard, durable surfaces that can withstand high pressure — but it can be risky if used incorrectly.
Key Benefits:
- Instantly removes visible dirt and grime
- Effective for heavy stains
- Great for textured or porous surfaces
- Quick, powerful cleaning method
Ideal For:
- Driveways and concrete
- Brick walls and paths
- Retaining walls
- Pavers and tiled patios
- Car parks and commercial surfaces
- Industrial exterior cleaning

When to Use Soft Washing in Tauranga
Soft washing is the best option for most home exteriors in Tauranga, especially when dealing with:
- Painted homes
- Mouldy weatherboards
- Older or heritage buildings
- Salt buildup near Mount Maunganui or Papamoa
- Roofs with visible moss or lichen
- Pre-paint preparation
It’s also a safer, longer-lasting solution for homes surrounded by trees, shade, or high humidity — all of which contribute to algae and mould growth.
When to Use Water Blasting in Tauranga
Water blasting is the go-to method for hard outdoor surfaces such as:
- Dirty concrete driveways
- Moss-covered paths or pavers
- Stained retaining walls
- Garage floors and exterior steps
- Grease or oil marks on parking areas
This method is great for quickly restoring large flat areas. However, it must be used with caution — especially near painted walls, wooden fences, or windows.
Real Case Example: Papamoa Mistake Turned Into a Soft Wash Save
A homeowner in Papamoa Beach attempted to water blast their painted timber cladding to remove black mould. Unfortunately, the high pressure stripped patches of paint, splintered the timber, and caused water intrusion into their eaves.
We were called in to fix the situation. After a full soft wash and mould treatment, the rest of the house was safely cleaned — and a repaint was scheduled to repair the damage. Lesson learned: not every surface can handle high pressure.
How We Use Both at Metro Water Blasting Tauranga
At Metro Water Blasting Tauranga, we tailor every job using the right method for the right surface.
We often combine:

Water Blasting Works Best For:
- Long, mossy driveways in Pyes Pā
- Commercial car parks and pathways in Tauriko
- Heavily stained concrete patios in Greerton
- Grit-covered footpaths near construction zones
- Oil-stained warehouse loading bays in industrial zones
Why Not Use Water Blasting Everywhere?
It might seem faster or more satisfying — but that jet of water can:
- Force water behind walls or under roofing
- Strip paint and cause costly repainting
- Damage timber, lead to rot, and loosen caulking
- Blow seals on windows or cause leaks into ceiling spaces
That’s why we always assess your surface type first, and never apply high pressure where it’s not suitable.
Common Mistakes to Avoid
- Using water blasting on painted surfaces
- Blasting timber decks or fences with high PSI
- Skipping pre-treatment when dealing with mould
- Using the wrong nozzle or angle
- Holding the lance too close to the surface
- Forgetting to clean up overspray or runoff
