If your home’s siding, roof, or fence is starting to look discolored or grimy, but you’re hesitant to blast it with high-pressure water, soft washing could be the perfect solution.


Soft washing is a safer alternative to traditional pressure washing—especially for delicate surfaces. For homeowners in Greenville, MS, it’s an effective way to restore your home’s beauty while preventing long-term damage caused by algae, mold, and mildew.


Let’s dive into what soft washing is, how it works, and why Pro Green, LLC recommends it for many exterior cleaning needs.


What Is Soft Washing?

Soft washing is a cleaning method that uses low-pressure water combined with eco-friendly chemical solutions to gently remove dirt, grime, mold, algae, and other organic buildup from exterior surfaces.


Unlike pressure washing—which uses high-pressure water (2,000+ PSI)—soft washing operates at pressures under 500 PSI, minimizing the risk of surface damage.


The cleaning solution typically includes:

  • Water
  • Biodegradable detergents
  • Sodium hypochlorite (a disinfectant)



This combo breaks down stains at the molecular level and continues to sanitize surfaces even after rinsing.


Soft Washing vs. Pressure Washing: What’s the Difference?

Feature Soft Washing Pressure Washing
Water Pressure Low (under 500 PSI) High (1,500–3,000+ PSI)
Ideal For Roofs, siding, fences, stucco Concrete, brick, stone, driveways
Cleaning Agent Yes – disinfecting solution Mostly water (detergent optional)
Risk of Damage Very low Higher, especially on soft surfaces
Longevity of Clean Longer lasting Shorter unless disinfectant is added

At Pro Green, we evaluate each surface before cleaning to determine which method will be both safe and effective.


What Surfaces Should Be Soft Washed?

In Greenville’s warm, humid climate, organic buildup can form quickly. Soft washing is ideal for removing this without damaging surfaces like:

  • Asphalt shingles (black streaks from algae)
  • Vinyl siding
  • Wood siding or fencing
  • Stucco or painted surfaces
  • Outdoor furniture
  • Screen enclosures


Using pressure washing on these surfaces can cause:

  • Water intrusion
  • Surface etching or paint removal
  • Shingle granule loss


Benefits of Soft Washing for Homeowners in Greenville, MS

1. Preserves Delicate Surfaces

Soft washing gently lifts dirt and contaminants without eroding or stripping your home’s exterior finishes.


2. Prevents Organic Growth from Returning

The treatment kills mold, algae, and bacteria at the root, preventing regrowth for up to 12–18 months—ideal for humid environments like the Mississippi Delta.


3. Improves Curb Appeal Instantly

A soft-washed home looks brighter, cleaner, and more welcoming. It’s a simple upgrade that can increase property value and pride of ownership.


4. Environmentally Friendly Solutions

Pro Green uses biodegradable, eco-safe solutions that are gentle on your landscaping and safe for pets and family.


5. Increases Roof Lifespan

By removing algae and lichen that deteriorate shingles, soft washing extends your roof’s life and prevents early replacement.


How Often Should You Soft Wash Your Home?

In Greenville’s climate, homes benefit from soft washing once every 12–18 months, depending on factors like:

  • Tree cover (shade encourages algae)
  • Rainfall and humidity
  • Windborne pollen and dust
  • HOA or neighborhood standards


Some homeowners also schedule soft washing before:

  • Listing a home for sale
  • Hosting a major event
  • Repainting or refinishing exterior areas
