Pressure washing and soft washing have become two of the most effective exterior cleaning solutions in recent years. Whether for residential or commercial properties, a clean and appealing exterior has many advantages. Depending on the surface and cleaning objective, pressure washing and soft washing can give you very distinct benefits. So, the question arises: What is the difference between these two?
In this blog, we will explore the key differences between pressure washing and soft washing to help you understand which method is best suited for your needs. We will look at different techniques, suitable surfaces and the overall effectiveness of both methods.
Understanding Pressure Washing
Definition and Technique
Pressure washing is a cleaning method that uses a high-pressure water spray to remove dirt, grime, mould, and other contaminants from surfaces. The pressure, ranging from 1,500 to 4,000 PSI (pounds per square inch), is powerful enough to strip away stubborn stains and buildup that regular cleaning methods cannot handle.
Suitable Surfaces
Pressure washing is ideal for hard, durable surfaces that are strong enough to withstand the force of high-pressure water. Common surfaces include:
- Driveways: Often made of concrete or asphalt, these surfaces accumulate oil stains, tire marks, and general dirt over time.
- Sidewalks: Public walkways are prone to dirt, gum, and other debris that require deep cleaning.
- Patios: Stone or brick patios can develop moss and grime, making them slippery and unsightly.
Effectiveness
The most significant advantage of pressure washing is that it can deliver immediate, visible results. The high-pressure water effectively removes years of dirt, grime, and mould in a matter of minutes, leaving the surface looking new. This method is particularly effective for all surfaces that see a lot of heavy foot traffic or are exposed to harsh weather conditions.
Pros and Cons of Pressure Washing
Pros
- Highly Effective for Tough Stains: Pressure washing can tackle the most stubborn stains and buildup, making it an excellent choice for heavily soiled areas.
- Quick Cleaning Method: The high pressure allows for fast cleaning, which is ideal for large areas or when time is of the essence.
- Ideal for Large Flat Areas: Surfaces like driveways, parking lots, and large patios benefit from the speed and efficiency of pressure washing.
Cons
- Can Cause Damage to Delicate Surfaces: The intense pressure can damage softer materials such as wood, vinyl siding, and shingles.
- Uses a Lot of Water: Pressure washing consumes a significant amount of water, which can be a concern in areas with water restrictions.
- Potential for Injury if Not Handled Properly: The high-pressure stream can cause serious injury if not used correctly, so always follow safety protocols.
Understanding Soft Washing
Definition and Technique
Unlike pressure washing, soft washing uses low-pressure water combined with specialized cleaning solutions to remove dirt, algae, mildew, and other contaminants. Due to the lower pressure, soft washing requires chemical agents to break down grime, allowing it to be gently rinsed away without the risk of surface damage.
Suitable Surfaces
Soft washing is designed for delicate surfaces that could be damaged by the force of high-pressure water. Common surfaces include:
- Roofs: Asphalt shingles, tiles, and other roofing materials are prone to algae and mould growth that can be safely removed with soft washing.
- Siding: Vinyl, wood, and other types of siding benefit from the gentle soft-washing approach.
- Decks: Wooden decks, particularly those made of softer woods, are ideal for soft washing.
Effectiveness
Soft washing is particularly effective at removing biological contaminants like algae, mildew, and mould. The chemical treatment cleans the surface and also inhibits the regrowth of these organisms, resulting in a longer-lasting clean. This method is particularly favoured for any surfaces where the integrity of the material is as important as the cleanliness.
Pros and Cons of Soft Washing
Pros
- Gentle on Surfaces: Soft washing minimizes the risk of damage to delicate surfaces, making it a safer option for wood, shingles, and vinyl siding.
- Uses Less Water: The combination of low-pressure washing and cleaning agents reduces the amount of water required for cleaning, making it a more environmentally friendly option.
- Longer-Lasting Results Due to Chemical Agents: The use of specialized cleaning solutions not only cleans but also prevents the return of contaminants like algae and mould, ensuring a cleaner surface for a longer period.
Cons
- Slower Process Compared to Pressure Washing: Soft washing generally takes longer because it involves the application of cleaning agents and a more thorough rinse process.
- Requires Specialized Cleaning Solutions: The need for chemical agents adds to the cost and makes soft washing a bit more complex.
- May Not Remove Heavy Stains as Effectively: Soft washing may not be as effective as pressure washing for surfaces with heavy staining or deep-seated dirt.
Comparing Pressure Washing and Soft Washing
Techniques
- Pressure Washing: Involves using high-pressure water alone to blast away dirt and grime. It is a straightforward method that relies on the force of water.
- Soft Washing: Combines low-pressure water with cleaning agents to break down dirt and biological contaminants. This method is gentler and more targeted in its approach.
Effectiveness
- Pressure Washing: Provides immediate, visible results and is better suited for rugged, durable surfaces where quick cleaning is needed.
- Soft Washing: Offers long-lasting cleanliness, especially on delicate surfaces, and is effective in preventing the regrowth of contaminants.
Suitable Surfaces
- Pressure Washing: Best for hard surfaces such as concrete, brick, and stone. Ideal for driveways, sidewalks, and large outdoor areas.
- Soft Washing: Ideal for fragile surfaces like roofs, siding, and wooden decks. Suitable for materials that require a gentle touch to avoid damage.
Choosing the Right Method for Your Needs
Assessing the Surface
The most significant factor to consider when deciding between pressure washing and soft washing is the surface you are cleaning. Hard, durable surfaces can withstand the force of pressure washing, while delicate surfaces may require the gentle cleaning method of soft washing.
Considering the Cleaning Objective
The cleaning objective is also a significant factor. If you need an immediate visible clean, pressure washing may be the better option. However, if you are looking for a long-term solution that prevents the return of contaminants, soft washing is the more appropriate choice.
Safety and Environmental Considerations
Pressure washing uses a significant amount of water and can cause damage if not handled properly. Soft washing uses less water and is safer for delicate surfaces, but it involves chemicals. Both methods require proper safety measures to ensure effective and safe cleaning.
