Pressure Washing vs. Soft Washing: What’s the Difference and Why It Matters

The Highlights

• Soft washing uses lower-pressure water combined with specialized cleaning solutions to gently clean more delicate surfaces like roof shingles and painted siding, effectively treating and preventing biological growth.
• Soft washing is noted for its gentleness and long-lasting results, as it not only cleans but also treats surfaces to prevent future growth of mold, mildew, and algae.
• The decision between pressure washing and soft washing depends on the surface material and the kind of contaminants present.

When it comes to maintaining the exterior of your home or business, choosing the right cleaning technique is crucial not only for aesthetic appeal, but also for the longevity of your property’s surfaces. Two popular methods, pressure washing and soft washing, offer unique benefits and are suited for different types of cleaning tasks. Understanding the differences between these methods can help you make an informed decision about the best way to care for your property. 

What Is Pressure Washing? 

Pressure washing uses high-pressure water spray to remove dirt, grime, mold, algae, and other pollutants from surfaces. This method is highly effective for cleaning hard surfaces such as concrete driveways, stone paths, and brick walls. The water pressure can be adjusted to suit different types of materials, ensuring a thorough clean without causing damage. 

Key Advantages of Pressure Washing: 

• Effectiveness: High-pressure water is excellent at breaking down tough stains and deep-seated dirt. 

• Speed: Pressure washing is a quick way to clean large surfaces like driveways, sidewalks, and decks. 

• Versatility: With different nozzle tips and settings, pressure washers can be used on a variety of surfaces. 

What Is Soft Washing? 

Soft washing is a gentler cleaning method that uses low-pressure water combined with special environmentally friendly cleaning products to remove dirt, bacteria, algae, and other organic stains. This method is particularly suited for cleaning softer surfaces like roof shingles, PVC siding, wood paneling, and painted surfaces. The cleaning solution used in soft washing also helps inhibit future biological growth, making it a more sustainable cleaning option. 

Key Advantages of Soft Washing: 

• Gentleness: Low-pressure water ensures that delicate surfaces are not damaged during the cleaning process. 

• Effectiveness on Organic Material: The biodegradable environmentally friendly cleaning products used in soft washing target mold, mildew, and algae, which are often difficult to remove with pressure washing alone. 

• Long-lasting Results: Since soft washing kills spores and other organic matter at the source, it often results in a cleaner surface for a longer period. 

Choosing Between Pressure Washing and Soft Washing 

The choice between pressure washing and soft washing largely depends on the type of surface you need to clean and the specific contaminants present. Here’s a quick guideline: 

• Use Pressure Washing for: 

• Hard surfaces that can withstand high pressure, such as concrete, brick, and stone. 

• Areas with heavy soiling or stubborn stains, such as oil or grease spots on driveways. 

• Use Soft Washing for: 

• Delicate surfaces that may be damaged by high pressure, like roof tiles, siding, materials involving adhesion, and some types of decking. 

• Surfaces prone to biological growth, such as shaded walls that may develop mold or algae. 

Choosing the wrong method can be ineffective and potentially damaging to your property. For example, using a high-pressure wash on old, brittle shingles can strip them of their protective granules. Conversely, using soft washing on oil-stained concrete might not be powerful enough to achieve the desired level of cleanliness.
