Best Practices for Soft Washing Your House or Deck 

Soft washing is an effective cleaning method that uses low-pressure water combined with specialized cleaning solutions to safely remove dirt, algae, mold, mildew, and other contaminants from exterior surfaces. Unlike pressure washing, which relies on high-pressure streams, soft washing gently cleans while protecting delicate materials such as siding, decks, and roofs. 

In Brampton and Toronto, where seasonal weather changes can lead to rapid buildup of grime and organic growth, soft washing has become an essential part of exterior home maintenance. This guide covers the best practices for soft washing your house or deck to ensure a thorough, safe, and long-lasting clean. 

Why Choose Soft Washing Over Pressure Washing 

While pressure washing can be effective for hard surfaces like concrete driveways, it can damage softer materials. Soft washing offers several advantages: 

• Protects wood, vinyl, and painted surfaces from cracking or stripping 

• Effectively removes organic growth at its root level 

• Uses eco-friendly cleaning solutions for safer results 

• Extends the lifespan of siding, decks, and roofing materials 

Best Practices for Soft Washing Your House or Deck 

1. Inspect the Surface Before Washing 

Before starting, check for any loose paint, cracked boards, or structural issues. Addressing these repairs first ensures the cleaning process does not worsen the damage. 

2. Choose the Right Cleaning Solution 

A key component of soft washing is the cleaning agent. 

• For mold and mildew removal, a diluted sodium hypochlorite solution is often used. 

• For general dirt and grime, mild biodegradable detergents are effective. 
  Always follow the manufacturer’s dilution guidelines to avoid damaging the surface. 

3. Use Low-Pressure Equipment 

Soft washing requires a pressure level of 500 PSI or less. High-pressure streams can erode wood fibers, strip paint, or cause water intrusion behind siding. 

4. Apply the Cleaning Solution Evenly 

Using a soft wash system or low-pressure sprayer, apply the cleaning solution from the bottom up to prevent streaking. Allow the solution to dwell for the recommended time to break down contaminants. 

5. Rinse Thoroughly 

After the dwell time, rinse with clean water using low pressure. Start from the top and work down to avoid leaving streaks. 

6. Protect Nearby Plants and Landscaping 

Before applying cleaning agents, wet plants and cover them with breathable tarps to prevent damage from overspray. 

7. Schedule Regular Maintenance 

In areas with high humidity or shaded spots, algae and mildew can return quickly. Plan soft washing every 12 to 18 months for optimal results. 

Soft Washing vs Pressure Washing: Key Differences 

Case Study: Deck Soft Washing in Brampton

Process followed:

2. A biodegradable deck cleaner with a mild algaecide was applied evenly. 

3. After 10 minutes of dwell time, the surface was gently rinsed. 

4. Plants surrounding the deck were watered before and after the process to prevent damage from overspray.
