Keeping the exterior of your property clean is not just about curb appeal, it also helps extend the life of surfaces and prevent costly repairs. Two common methods used for exterior cleaning are soft washing and pressure washing. While they both work well for cleaning exterior surfaces, each method has its own strengths, limitations, and best use cases. Choosing the right approach depends on the type of surface, the level of dirt or buildup, and the overall condition of the material being cleaned.
What Is Pressure Washing?
Pressure washing uses high pressure water, often between 1,300 to 3,000 PSI, to blast away dirt, mold, mildew, grease, and other tough buildups. It’s effective for:
- Concrete driveways and sidewalks: Removes deep stains, dirt, and algae.
- Brick walls: Can strip away grime and moss.
- Metal surfaces: Great for removing rust and paint flakes.
Because of its strength, pressure washing should be handled with care. The force of water can damage softer surfaces like wood siding, roof shingles, or painted finishes if not used correctly.
What Is Soft Washing?
Soft washing uses low-pressure water combined with specialized cleaning solutions to remove dirt, algae, mold, and bacteria. Instead of relying on the sheer force of water pressure, soft washing cleans at the chemical level by killing organic growth and preventing it from quickly returning.
Soft washing is best suited for:
- Roof cleaning: Removes algae and moss without loosening shingles.
- Stucco and siding: Cleans without cracks and water penetration.
- Decks and fences: Gentle enough for wood, effective at killing mold.
- Painted surfaces: Protects paint while cleaning thoroughly.
Key Differences Between Soft Wash and Pressure Wash
| Factor | Soft Wash | Pressure Wash |
| Water Pressure | Low (under 500 PSI) | High (1,300–3,000+ PSI) |
| Cleaning Method | Cleans with chemical solutions | Cleans with water force |
| Best For | Roofs, siding, wood, painted surfaces | Concrete, stone, brick, metal |
| Risk of Damage | Lower with proper chemical handling | Higher if performed incorrectly |
| Long Term Results | Kills algae, mold, bacteria at the source | Removes surface stains and grime |
Choosing the Right Method for Your Property
When deciding between soft washing and pressure washing, consider these factors:
- Type of Surface – Fragile materials like wood, stucco, and roofing shingles require soft washing. Strong, durable surfaces like concrete or brick can handle pressure washing.
- Level of Dirt and Growth – Heavy stains or oil spills may need pressure washing, while mold, mildew, and algae are better treated with soft washing.
- Longevity of Results – Soft washing often provides longer lasting results since it kills organic matter at its root.
- Manufacturer or Contractor Recommendations – Some roofing and siding manufacturers specify soft washing to protect warranties.
Final Thoughts
Both soft wash and pressure wash have their place in property maintenance. Pressure washing is the right choice when you need force to remove stubborn buildup on hard surfaces while soft washing is safer for delicate materials and killing organic growth.
Oftentimes, the best approach for cleaning your property is a combination of both, but choosing the right cleaning method for the right reasons helps protect your property and maintain its appearance for years to come.
