What Is Soft Washing? A Complete Guide to Chemical Softwash

Mar 23, 2026

When it comes to cleaning the exterior of your home or commercial property, not all methods are created equal. Traditional pressure washing can be effective for some surfaces—but for many materials, it can actually cause damage. That’s where soft washing comes in. If you’ve heard the terms chemical softwash or chemical soft wash, you might be wondering what they mean and why they’re becoming the industry standard.

What Is Soft Washing?

Soft washing is a cleaning method that uses low-pressure water combined with specialized cleaning solutions to safely remove organic growth, dirt, and contaminants from exterior surfaces. Unlike pressure washing, which relies on high force, soft washing focuses on treating and eliminating the root cause of stains—such as algae, mold, mildew, and bacteria.

This process is often referred to as a chemical softwash or chemical soft wash because the cleaning power comes primarily from the solution itself, not the pressure of the water. The result is a deeper, longer-lasting clean without the risk of surface damage.

How Does a Chemical Softwash Work?

A professional chemical soft wash system uses a carefully balanced mix of cleaning agents—typically including sodium hypochlorite (a biodegradable disinfectant), surfactants, and water. This solution is applied gently to surfaces, where it:

  • Breaks down organic growth at the root
  • Kills algae, mold, and mildew spores
  • Lifts dirt and grime from the surface
  • Prevents regrowth for an extended period

After the solution has had time to dwell and do its job, it is rinsed away using low-pressure water, leaving surfaces clean and sanitized.

Where Is Soft Washing Used?

Soft washing is ideal for a wide range of exterior surfaces, especially those that can be damaged by high pressure. Common applications include:

  • Roof cleaning (asphalt shingles, tile, slate)
  • Vinyl and wood siding
  • Decks and fences
  • Stucco and painted surfaces
  • Solar panels and delicate exteriors

At Pura Softwash, we utilize advanced chemical softwash techniques—including drone-assisted applications—to safely clean even hard-to-reach areas without ladders or lifts.

Benefits of Chemical Softwashing

Choosing a chemical soft wash over traditional pressure washing offers several key advantages:

1. Protects Your Property
Low-pressure application prevents damage to shingles, siding, and other delicate materials.

2. Longer-Lasting Results
Because a chemical softwash kills organic growth at the source, surfaces stay cleaner for longer compared to pressure washing alone.

3. Improves Curb Appeal
Removes unsightly black streaks, green algae, and buildup—instantly enhancing the look of your home or business.

4. Eco-Conscious Approach
When done correctly with proper dilution and plant protection measures, chemical soft wash solutions are safe for your landscaping and surrounding environment.

Soft Washing vs. Pressure Washing

While both methods have their place, the key difference comes down to force vs. treatment:

  • Pressure Washing: Uses high pressure to blast away dirt (can damage surfaces if misused)
  • Soft Washing: Uses a chemical softwash solution to clean and sanitize at low pressure

For most residential and commercial exterior cleaning needs—especially roofs and siding—soft washing is the safer and more effective choice.
