Concrete & Driveways
Concrete is tough and porous. High-pressure water blasts out embedded dirt, oil, and tire marks that soft washing can't fully remove.

At a Glance: The Key Differences
Both methods clean your exterior, but they work very differently. Here's how to tell them apart.
Feature
Pressure Washing
Soft Washing
Water Pressure
1,300–4,000+ PSI
Under 500 PSI
Cleaning Agent
Water only (or mild detergent)
Biodegradable algaecides & surfactants
How It Cleans
Blasts dirt and grime away
Kills organic growth at the root, then rinses
Best Surfaces
Concrete, brick, stone, pavers
Siding, roofs, fences, wood decks
Risk of Damage
Low on hard surfaces; high on siding/roofs
Very low — safe for all exterior surfaces
Result Longevity
Cleans visible buildup
Kills roots; stays cleaner longer
What Is Pressure Washing?
Pressure washing (also called power washing) uses a high-pressure stream of water — typically between 1,300 and 4,000 PSI — to blast away dirt, grime, oil stains, and organic buildup from hard surfaces.
It's the fastest, most effective way to clean concrete driveways, brick walkways, stone patios, and block walls. The force of the water does the heavy lifting, so no chemicals are needed for most jobs.
Best for:
- Concrete driveways & walkways
- Brick & stone walls
- Pavers & pool decks
- Commercial parking lots
What Is Soft Washing?
Soft washing is a low-pressure cleaning method that uses specially formulated, biodegradable cleaning solutions to kill algae, mildew, mold, and bacteria at the source — then gently rinses them away with low-pressure water.
Instead of relying on brute force, soft washing relies on chemistry. The solution penetrates the surface, destroys organic growth down to the root, and leaves your exterior cleaner for longer. Because it uses under 500 PSI, it's completely safe for roofs, siding, and delicate materials.
Best for:
- Vinyl, brick & stucco siding
- Asphalt shingle & tile roofs
- Wood & vinyl fences
- Soffits, gutters & eaves
Which Method for Which Surface?
Here's a quick reference for every exterior surface on a typical Cypress-area home.
Pressure Washing
House Siding
Vinyl, brick, stucco, and fiber cement can all be damaged by high pressure. Soft wash solutions safely kill algae and mildew without forcing water behind panels.
Roofs & Shingles
High pressure will strip granules from asphalt shingles and void warranties. Soft washing is the only manufacturer-recommended cleaning method for roofs.
Wood & Vinyl Fences
High pressure splinters wood and can warp vinyl boards. Soft washing cleans fences gently while preserving their finish and structural integrity.
Brick & Stone Walls
Brick and natural stone are durable enough for pressure washing, which restores their original color by removing ground-in grime and efflorescence.
Patios & Pool Decks
Concrete, pavers, and stone pool decks collect slippery algae and deep stains. Pressure washing restores traction and a clean, even appearance.
Why Using the Wrong Method Matters
Pressure Washing Damage Risks
- • Forces water behind vinyl siding, causing mold inside walls
- • Strips granules from asphalt shingles and voids manufacturer warranties
- • Cracks stucco and chips paint on wood surfaces
- • Splinters wood decks and fences
Soft Washing Safety Benefits
- • Kills algae and mildew at the root for a longer-lasting clean
- • Gentle enough for roofs, siding, and painted surfaces
- • Biodegradable solutions safe for plants and pets when used correctly
- • Restores curb appeal without risk of surface damage
Roofs Must Be Soft Washed
This is the most important rule in exterior cleaning: never use high pressure on a roof.
Asphalt shingle manufacturers explicitly void warranties if high-pressure cleaning is used. The granules that protect your shingles from UV damage will be stripped away, dramatically shortening your roof's lifespan.
Soft wash roof cleaning is the only ARMA-recommended method. It safely removes black algae streaks (Gloeocapsa magma), moss, and lichen without damaging shingles or tiles.
Soft Wash vs Pressure Wash FAQs
Not exactly. Soft washing uses specially formulated cleaning solutions that kill algae, mildew, and mold at the root, combined with low-pressure water to rinse them away. It's the cleaning solution doing the work, not the pressure. Pressure washing relies on high-pressure water to blast dirt off hard surfaces.
Yes. High pressure can force water behind siding, strip paint, crack stucco, and dislodge or break shingles. That's why soft washing is the only safe method for roofs, siding, and other delicate exterior surfaces.
Pressure washing is better for concrete and other hard, porous surfaces. The high pressure effectively removes embedded dirt, oil stains, and mildew that a soft wash alone can't lift from porous concrete.
Soft wash solutions contain surfactants and algaecides that kill organic growth at the source. The dead algae and mildew are then gently rinsed away, and the treatment helps prevent regrowth for months longer than pressure washing alone.
Costs are similar and depend more on the size of the job and type of surface than on the method. A driveway pressure wash might run $150–$350, while a full house soft wash is typically $250–$450. We always provide a free written quote before starting.
DIY soft washing is possible but risky without the right solutions and equipment. Using the wrong chemical mix can damage plants, stain siding, or leave residue. Professional soft washers have commercial-grade equipment, trained technicians, and proper insurance.
Soft washing typically lasts longer on organic growth because it kills the source. Pressure washing removes visible buildup but may leave microscopic roots that regrow quickly. On hard surfaces like concrete, both methods deliver similar longevity.
