The Benefits of Soft Washing for Your Home and Business

Revised by Bruce Hulse

If you are among the many who have ever wondered what the difference is between pressure washing and soft washing, do not stress. Clear Ottawa is here to fill you in. Many homeowners and business owners have asked us about our soft wash services, so this article explains the basics: where soft washing comes from, how it differs from pressure or power washing, and why it is a safer and more effective cleaning solution for your property. Use this guide to make an informed decision about your next exterior cleaning service.

Key Summary

• Soft washing uses low-pressure water combined with biodegradable cleaning solutions to remove algae, mold, dirt, and bacteria safely.
• Unlike pressure washing, it targets the root cause of stains (such as bacteria like Gloeocapsa magma) instead of just blasting away surface buildup.
• It is safe for delicate surfaces such as siding, shingles, stucco, and wood, where high pressure could cause costly damage.
• Eco-friendly benefits include lower water consumption, biodegradable chemicals, and reduced environmental impact.
• Results last four to six times longer than traditional pressure washing, saving both money and maintenance time.

History of Soft Wash

Soft washing originated in 1992 with AC Lockyer, a Florida entrepreneur with a background in horticulture. He developed the process to remove algae streaking on roofs without relying on destructive high-pressure washing. By combining his plant science knowledge with cleaning methods, he discovered that a specialized cleaning solution could not only wash away stains but also kill the root causes of organic growth.

After Hurricane Andrew devastated his region and left him without roofing jobs, Lockyer adapted his “Green Wash” solution to clean siding, stucco, and brick surfaces. The results were remarkable, and soft washing quickly gained popularity as a safer, longer-lasting alternative to traditional pressure washing.

Today, soft washing is widely recognized across North America as one of the most effective methods for exterior property maintenance. It is trusted by both residential and commercial property owners who value long-term results, environmental responsibility, and surface protection.

What Is Soft Wash?

Soft washing is a cleaning method that uses low-pressure nozzles combined with biodegradable cleaning agents. The unique combination allows it to remove contaminants such as:

• Algae streaks on roofs
• Mold and mildew growth
• Moss and lichen patches
• Bacteria such as Gloeocapsa magma
• Dirt, pollen, and dust

The cleaning solution works on a microscopic level. Rather than scraping away the surface, it penetrates porous materials and kills the root organisms causing staining and decay. This process sanitizes the surface and ensures that the growth will not return quickly.

Surfaces Suitable for Soft Washing

• Asphalt shingles
• Vinyl siding
• Stucco walls
• Brickwork
• Wood fences and decks
• Clay roof tiles
• Composite and engineered materials
• Painted or coated masonry

This versatility makes it an excellent choice for both homes and businesses. From restoring curb appeal to protecting expensive materials, soft washing is a preventative solution that goes beyond simple cleaning.

Soft Wash vs. Pressure Wash

It is important to understand where each method shines and where it should be avoided.

Why Pressure Washing Can Be Risky

Pressure washing relies solely on the force of water. While effective for blasting away dirt on concrete, it can be too aggressive for most building materials. High pressure can strip away protective coatings, break shingles, force water behind siding, or even crack softer materials. Homeowners often call Clear Ottawa after discovering damage caused by improper pressure washing techniques.

Another drawback is that pressure washing only cuts off the visible portion of the problem. Organic growth, such as algae, often regrows faster after pressure washing, just like trimming weeds in a garden without removing the roots. This is why many homeowners feel like they need to pressure wash again and again.

Why Soft Washing Delivers Longer-Lasting Results

Soft washing addresses the root of the problem. By using specialized cleaning solutions, it not only removes the visible stains but also destroys the bacteria, fungi, and algae colonies causing them. This means surfaces stay clean for much longer. In most cases, soft washing results can last three to four years, compared to one season with pressure washing.

Benefits of Choosing Soft Wash

Soft washing is more than a cleaning method. It is a preventive care system for your property.

Additional Advantages

1. Protects Property Value
   A well-maintained property looks better, sells faster, and retains its value. Regular soft washing prevents premature aging and deterioration of your home or business exterior.
2. Improves Health and Safety
   Mold, mildew, and algae are not only unsightly but can also contribute to health issues, especially for those with allergies or respiratory concerns. By sanitizing surfaces, soft washing improves the safety of your living or working environment.
3. Enhances Curb Appeal
   First impressions matter. Whether you are welcoming guests, customers, or potential buyers, a clean exterior creates a positive impression and demonstrates pride in ownership.
4. Saves Time and Effort
   Because results last longer, you will not have to schedule exterior cleaning nearly as often. This reduces hassle and gives you peace of mind knowing your property is protected.

Conclusion

Choosing soft washing is one of the smartest ways to care for your home or business. It is gentle enough to protect delicate materials, powerful enough to eliminate tough stains at the root, and environmentally responsible. Soft washing can be applied to roofing, siding, patios, fences, and brick surfaces without damaging them, and it keeps your property cleaner for longer periods of time.

Just like pressure washing, however, soft washing requires training and expertise. When handled incorrectly, the cleaning solutions could harm plants or landscaping. This is why it is important to trust professionals. At Clear Ottawa, our team takes every precaution to shield and rinse greenery before, during, and after the wash.

For reliable, safe, and long-lasting cleaning, trust Clear Ottawa’s experienced technicians.
