Soft washing is one of the most effective cleaning methods, using low pressure and specialized cleaning solutions to remove dirt, algae, mold, and mildew from surfaces without causing damage.
At Hydro Clean, we've been providing professional soft washing services throughout Western North Carolina for over 21 years. Throughout this time, we've encountered numerous misconceptions about soft washing that prevent property owners from choosing this gentle yet highly effective cleaning method. In this blog, we'll address and debunk the most common myths about soft washing to help you make an informed decision about your property's maintenance.
What Is Soft Washing?
Before diving into the myths, let's clarify what soft washing actually entails. Soft washing is a cleaning method that uses low-pressure water application (typically below 500 PSI) combined with specialized biodegradable cleaning solutions. This technique is designed to remove dirt, grime, organic growth, and stains from exterior surfaces without the potential damage that can come from high-pressure washing.
The key components of soft washing include:
- Low-pressure water application
- Specialized biodegradable cleaning solutions
- Appropriate dwell time to allow the solution to work
- Gentle rinsing to remove loosened contaminants
Now, let's address the common myths that surround this effective cleaning method.
Myth #1: Soft Washing Is Just Pressure Washing with Less Pressure
One of the most prevalent misconceptions is that soft washing is simply pressure washing at a lower setting. This couldn't be further from the truth.
The Reality:
Soft washing and pressure washing are fundamentally different approaches to cleaning exterior surfaces. While both methods use water, the similarities largely end there:
- Cleaning Mechanism: Pressure washing relies primarily on mechanical force (water pressure) to blast away dirt and grime. Soft washing, on the other hand, uses specialized cleaning solutions that break down organic matter at the molecular level, with the low-pressure water serving mainly as a delivery and rinsing system.
- Equipment: Soft washing requires specialized equipment designed for the application of cleaning solutions, which is different from traditional pressure washing equipment.
- Technique: Soft washing involves applying solutions, allowing proper dwell time for the chemicals to work, and then gently rinsing - a more methodical process than the immediate blasting approach of pressure washing.
At Hydro Clean, we understand this distinction clearly. Our soft washing approach uses less than 1,000 PSI along with a 40-degree wide-angle nozzle and biodegradable solutions to effectively clean surfaces without relying on destructive force.
Myth #2: The Chemicals Used in Soft Washing Are Harmful to the Environment
Many property owners express concern about the environmental impact of the cleaning solutions used in soft washing.
The Reality:
While it's true that soft washing uses cleaning solutions, professional soft washing services like ours at Hydro Clean use biodegradable solutions that are environmentally responsible when applied correctly.
- Biodegradable Solutions: Our cleaning agents break down naturally in the environment, minimizing long-term impact.
- Proper Dilution: Professional soft washing services carefully dilute chemicals to the minimum effective concentration, reducing potential environmental impact while maintaining cleaning efficacy.
- Plant Protection Protocols: Before beginning any soft washing project, we take measures to protect surrounding vegetation, including pre-wetting plants and covering sensitive landscaping when necessary.
- Controlled Runoff: Professional services manage runoff appropriately to prevent concentrated solutions from entering waterways or harming local ecosystems.
The biodegradable solutions we use are far more environmentally friendly than allowing harmful organisms like mold, mildew, and algae to continue growing on your property. These growths can release spores and toxins into the surrounding environment, potentially causing more harm than properly applied cleaning solutions.

Myth #3: Soft Washing Doesn't Clean as Thoroughly as Pressure Washing
Some believe that without high pressure, soft washing can't possibly clean as effectively as traditional pressure washing.
The Reality:
Soft washing often provides more thorough cleaning results than pressure washing, particularly for certain types of contaminants and surfaces.
- Root-Level Cleaning: While pressure washing may visibly remove surface growth, it often doesn't kill the root systems of organisms like algae and mold. Soft washing's chemical approach kills these organisms at the root level, preventing quick regrowth.
- Penetration into Porous Surfaces: The cleaning solutions used in soft washing can penetrate microscopic pores in surfaces where high-pressure water cannot reach, providing a deeper clean.
- More Complete Removal: For biological growths like mold, mildew, and algae, soft washing is actually more effective because it kills the organisms rather than just blasting away their visible portions.
- Longer-Lasting Results: Because soft washing addresses the root cause of biological growth, results typically last 4-6 times longer than pressure washing alone.
At Hydro Clean, our customers are often surprised by how much brighter their homes and buildings look after a soft washing treatment. This is because the method truly cleans the surface rather than just removing the top layer of visible dirt.
Myth #4: Soft Washing Is Only for Delicate Surfaces
Many people believe soft washing is only necessary for fragile materials that would be damaged by pressure washing.
The Reality:
While soft washing is indeed excellent for delicate surfaces, its benefits extend to virtually all exterior surfaces, including those that could technically withstand pressure washing.
Surfaces that benefit from soft washing include:
- Roofs: Asphalt shingles, metal, tile, and other roofing materials
- Siding: Vinyl, wood, fiber cement, stucco, and brick
- Decks and Fences: Wooden, composite, and vinyl
- Concrete and Pavers: Driveways, walkways, patios, and retaining walls
- Gutters and Soffits: Aluminum, vinyl, and painted surfaces
Even surfaces that aren't physically damaged by pressure washing often benefit more from soft washing because of the superior cleaning results and longer-lasting effects. This applies particularly to surfaces prone to biological growth like algae and mold.

Myth #5: Soft Washing Is More Expensive Than Pressure Washing
Cost concerns often lead property owners to choose pressure washing over soft washing, believing it to be the more economical option.
The Reality:
While the initial cost of soft washing might sometimes be slightly higher than basic pressure washing (though not always), the long-term value makes it the more economical choice for most properties.
Factors that affect the true cost comparison include:
- Frequency of Cleaning: Soft washing results typically last 4-6 times longer than pressure washing, reducing the number of cleanings needed over time.
- Preventative Benefits: Soft washing helps prevent premature deterioration of surfaces by eliminating harmful biological growth, potentially saving significant repair or replacement costs.
- Reduced Water Usage: Soft washing often uses less water than pressure washing, which can be a consideration in areas with water restrictions or higher water costs.
- Property Protection: The gentler approach of soft washing reduces the risk of damage that might require costly repairs.
When considering the full lifecycle cost rather than just the initial service price, soft washing often emerges as the more cost-effective solution.
Myth #6: Soft Washing Will Damage Plants and Landscaping
Concern for landscaping often makes property owners hesitant to choose soft washing.
The Reality:
When performed correctly by professionals, soft washing poses minimal risk to surrounding vegetation.
Professional soft washing services take specific precautions to protect plants:
- Pre-treatment rinsing: Thoroughly wetting plants with water before cleaning begins helps dilute any solution that might come into contact with them.
- Proper application techniques: Controlled spraying and careful application minimize overspray and runoff.
- Plant-friendly formulations: Professional solutions are designed to break down quickly and cause minimal harm when used properly.
- Post-treatment rinsing: Additional rinsing of any plants that may have been exposed to cleaning solutions helps further protect them.
With these precautions in place, soft washing typically poses no significant threat to established landscaping. In our extensive experience at Hydro Clean, plant damage is extremely rare when proper protocols are followed.
Myth #7: Soft Washing Results Don't Last
Some property owners believe that without the "deep cleaning" of high-pressure washing, soft washing results will be short-lived.
The Reality:
Soft washing actually provides longer-lasting results than pressure washing in most scenarios, particularly when dealing with biological growth like algae, mold, and mildew.
The reasons for this superior longevity include:
- Elimination vs. Removal: Soft washing kills organisms rather than simply removing their visible portions, preventing quick regrowth from surviving roots or spores.
- Residual Protection: Some soft washing solutions leave a slight residual effect that continues to inhibit new growth for a period after cleaning.
- Complete Surface Treatment: Soft washing treats entire surfaces uniformly, including cracks and crevices where contaminants might hide and later spread.
Our clients at Hydro Clean often notice that soft washing increases the amount of time they can go between cleanings since the method actually kills the bacteria rather than just removing it from the surface.
Myth #8: Soft Washing Can't Remove Tough Stains
Another common misconception is that without high pressure, soft washing can't handle stubborn stains like rust, hard water deposits, or oil.
The Reality:
Soft washing can be extremely effective at removing tough stains, often more so than pressure washing alone, because it combines chemical cleaning action with appropriate pressure.
Different types of stains require different approaches:
- Organic Stains (algae, mold, mildew): These respond exceptionally well to soft washing's biocidal components.
- Mineral Deposits (hard water stains, efflorescence): Soft washing solutions often include ingredients that dissolve these deposits more effectively than water pressure alone.
- Oil and Grease: Specialized degreasing agents can be incorporated into soft washing solutions to break down these substances.
- Rust and Metal Stains: While some of the most challenging stains, many can be addressed with specialized soft washing formulations.
Professional soft washing services assess the specific types of staining present and adjust their solution formulations accordingly, often achieving superior results to one-size-fits-all pressure washing.
