Many homeowners often struggle to choose between pressure washing and soft washing. Both methods are highly effective, but they serve different purposes and require different approaches. However, choosing the wrong cleaning method can lead to costly damage, such as eroded surfaces, stripped paint, or water infiltration that encourages mould growth. In this blog, we will help you avoid such issues by going over all the differences between pressure washing and soft washing to determine which technique is best suited for your specific cleaning needs.
Pressure Washing vs Soft Washing
What is Soft Washing?
Soft washing is a low-pressure cleaning method that relies on specially formulated cleaning solutions rather than high-pressure water to break down dirt, algae, mould, and other contaminants on surfaces. Unlike traditional power washing, which can be too forceful for certain materials, soft washing provides a gentle yet effective alternative. It is particularly beneficial for cleaning fragile surfaces like roof shingles, vinyl siding, painted wood, and stucco.
What is Pressure Washing?
Pressure washing is a cleaning technique that uses a high-pressure stream of water to remove dirt, grime, mould, and stains from surfaces. Unlike soft washing, pressure washing relies on the force of water rather than chemical solutions to break down and wash away contaminants. This method is highly effective for hard, durable surfaces that can withstand strong water pressure.
Pressure washing is an excellent option for removing built-up dirt, grease, and even loose paint from outdoor surfaces. However, it requires careful handling, as excessive pressure can cause damage to certain materials, leading to costly repairs.
When to Use Soft Washing
Soft washing is ideal for surfaces that are prone to damage from high pressure or require a delicate touch to maintain their structure and appearance. It is the preferred method for cleaning roofs, as high-pressure water can dislodge shingles or force water under roofing materials, leading to leaks and water damage. It is also recommended for wooden decks and fences, which can splinter or warp under intense pressure.
Soft washing is highly effective in removing a wide range of stains caused by organic growth and environmental pollutants. Here are some statins that soft washing tackles:
- Algae and mould, which commonly grow on damp surfaces, can be safely eliminated using soft washing techniques.
- Pollen and dust, which accumulate on exterior walls and outdoor furniture, can be easily rinsed away, leaving surfaces looking fresh and clean.
- Bird droppings, which contain acidic compounds that can damage surfaces, can be broken down and washed away without the need for harsh scrubbing.
- Soft washing is also effective against rust stains that develop on non-metallic surfaces, restoring their original appearance without the need for abrasive cleaning.
Since the cleaning solution is designed to penetrate porous surfaces, soft washing can remove deep-seated stains that would be difficult to eliminate with traditional scrubbing alone.
When to Use Pressure Washing
Pressure washing is best suited for surfaces that can endure high water pressure without sustaining damage. Below are some surfaces that can be pressure washed:
- Concrete driveways and walkways are ideal candidates, as the strong water jets can effectively remove deep-set stains, tyre marks, and accumulated grime.
- Brick and stone exteriors also benefit from pressure washing, as the force of the water can dislodge moss, lichen, and other debris that build up over time.
- Patios and pool decks, which are frequently exposed to moisture and develop mould and mildew, can be thoroughly cleaned with pressure washing, restoring their original look.
- Metal surfaces, such as garage doors and steel fences, can also be cleaned using this method, as it removes rust and old paint efficiently.
While pressure washing is highly effective, it should only be used on surfaces designed to handle high-impact cleaning.
How Soft Washing Works
Soft washing involves a multistep cleaning process. First, a specialised biodegradable cleaning solution is applied to the surface, typically using a low-pressure sprayer. This solution contains detergents, surfactants, and algaecides that break down and dissolve organic stains caused by mould, mildew, algae, and bacteria.
Once the cleaning agents have done their job, the surface is gently rinsed with a controlled stream of water, washing away the loosened dirt and biological matter.
Risks and Precautions of Pressure Washing
Despite its effectiveness, pressure washing comes with certain risks if not performed correctly.
High-pressure water can erode surfaces, causing premature wear and tear on materials like wood, brick-and-mortar, and painted surfaces. Water can also be forced into cracks and crevices, leading to hidden mould growth and structural damage. The intense force of pressure washing can strip away paint and protective coatings, requiring costly repainting or refinishing.
In order to avoid these risks, it is crucial to use the correct pressure settings and techniques or hire a professional who has experience with pressure washing equipment.
Soft Washing vs. Pressure Washing: Which Is Best for Your Home?
Determining whether soft washing or pressure washing is the right choice depends on various factors, including the type of surface, the severity of the issue, the risk of damage, and the environmental impact.
Soft washing is the preferred method for delicate surfaces that require gentle cleaning, while pressure washing is better suited for hard surfaces that need deep cleaning. Soft washing is more effective for removing organic stains like mould and algae, whereas pressure washing works well on tough stains such as oil and graffiti. Additionally, soft washing uses biodegradable chemicals that are safer for the environment, while pressure washing can cause runoff pollution if not handled properly.
