What is Soft Washing? The Safe and Effective Way to Clean Your Home’s Exterior

When you think about cleaning the outside of your house, powerful pressure washing might immediately come to mind. However, there’s a smarter, safer, and often more effective method for many surfaces: **Soft Washing**. At **EdgeFlow**, we utilize professional soft washing techniques extensively across Sydney because it delivers exceptional results without the risks associated with high pressure. Let’s explore what soft washing is and why it’s often the superior choice.

What Exactly is Soft Washing?

Soft washing is an exterior cleaning technique that relies primarily on specialized cleaning solutions rather than high water pressure to do the work. Key characteristics include:

• Low Pressure Application: The water pressure used is typically very low, often comparable to or just slightly stronger than a standard garden hose (usually well under 500 PSI, sometimes even under 100 PSI).
• Specialized Cleaning Solutions: Biodegradable solutions are applied to the surface. These are specifically formulated to kill organic growths like mould, mildew, algae, and lichen, and to break down dirt, grime, and other contaminants.
• Dwell Time: The solutions are allowed to sit on the surface for a specific period (dwell time) to effectively neutralize organic matter and loosen dirt.
• Low Pressure Rinse: The surface is then thoroughly rinsed with clean water at low pressure, washing away the dead organisms, dirt, and cleaning solution residue.

Essentially, **soft washing cleans surfaces by treating the root cause of the staining (often biological growth) rather than just blasting away the visible layer with force.**

Soft Washing vs. High Pressure Washing: The Key Differences

Understanding the distinction is crucial:

• Pressure: Soft Washing uses very low pressure; High Pressure Washing uses very high PSI. See our guide on understanding cleaning pressure.
• Mechanism: Soft Washing relies on cleaning solutions; High Pressure Washing relies on water force.
• Safety for Surfaces: Soft Washing is safe for virtually all exterior building materials; High Pressure Washing can easily damage siding, paint, wood, roofs, and seals. Read about the risks in our pressure cleaning house guide.
• Effectiveness on Organic Growth: Soft Washing kills spores, leading to longer-lasting results; High Pressure Washing might just remove the surface growth, allowing it to return faster.

Benefits of Using Soft Washing for Exterior Cleaning

Choosing soft washing, especially from professionals like EdgeFlow, offers significant advantages:

• Unmatched Safety for Delicate Surfaces: It’s the recommended method for cleaning vinyl siding, render (stucco), weatherboards, painted surfaces, timber features, Colorbond®, asphalt shingles, and more without risk of etching, stripping, or forcing water intrusion.
• Highly Effective Organic Growth Removal: The specialized solutions effectively kill mould, mildew, algae, lichen, and bacteria deep down, sanitizing the surface.
• Longer-Lasting Cleanliness: By eliminating organic growth at the source, the clean appearance typically lasts much longer compared to just using pressure.
• Reduced Risk of Water Damage: The low pressure significantly minimizes the chance of forcing water behind cladding, under roof tiles, or into sensitive areas.
• Often More Eco-Friendly: Professional soft washing services like EdgeFlow’s often use biodegradable solutions, and the lower water volume compared to constant high-pressure rinsing can be more water-efficient overall.
• Restores Appearance Gently: Brightens surfaces and restores colour without abrasive force.

Surfaces Where Soft Washing is the Preferred Method (Especially in Sydney)

Given the variety of building materials used across Sydney, soft washing is the ideal technique for:

• House Washing: Cleaning render, weatherboards (timber or composite), vinyl cladding, painted brick, etc.
• Roof Cleaning: Safely cleaning terracotta tiles, concrete tiles, and Colorbond® metal roofing without damaging the surface or compromising integrity.
• Painted Surfaces: Cleaning fascias, eaves, gutters, window frames, doors.
• Wooden Decks and Fences: Often a much safer alternative to pressure washing for preserving wood integrity (see our deck cleaning info). Link to fence cleaning page.
• Stucco and EIFS (Exterior Insulation and Finish Systems): These cladding systems require very gentle cleaning.
