Not all exterior cleaning is the same. Understanding when to use soft washing versus pressure washing can mean the difference between a spotless home and costly damage.
If you've looked into getting your home's exterior cleaned, you've probably seen the terms "soft washing" and "pressure washing" used interchangeably. But they're actually two very different methods, and using the wrong one on the wrong surface can cause serious damage.
What Is Pressure Washing?
Pressure washing uses high-pressure water — typically between 2,500 and 4,000 PSI — to blast away dirt, grime, oil stains, and buildup from hard surfaces. The force of the water does the heavy lifting.
Best for:
- Concrete driveways and sidewalks
- Concrete patios
- Parking lots and commercial concrete surfaces
Not safe for:
- Vinyl siding
- Brick
- Hardie board
- Stucco
- Wood surfaces
- Painted surfaces
What Is Soft Washing?
Soft washing uses low-pressure water (typically under 500 PSI) combined with specialized, biodegradable cleaning solutions. Instead of relying on force, the cleaning solutions do the work — killing mold, mildew, algae, and bacteria at the root.
Best for:
- All siding types: vinyl, brick, Hardie board, stucco, aluminum, and wood
- Roofs
- Fences (especially wood)
- Decks
- Painted surfaces
- Any surface that could be damaged by high pressure
Why the Distinction Matters
Using high-pressure water on your home's siding can:
- Force water behind siding and into wall cavities, causing mold and rot
- Crack or chip brick and mortar joints
- Gouge and splinter wood on decks and fences
- Strip paint and protective coatings
- Damage window seals and screens
We've seen homeowners attempt to pressure wash their vinyl siding with a rented machine, only to end up with water damage inside their walls. The repair costs far exceeded what professional soft washing would have cost.
How Splash Pressure Washing Approaches Each Job
At Splash Pressure Washing, we assess every surface before we start cleaning. Our approach is simple:
1. Concrete surfaces (driveways, sidewalks, patios) get pressure washed with commercial-grade surface cleaners for even, thorough results.
2. Siding, fences, decks, and delicate surfaces get soft washed with professional-grade cleaning solutions that kill organic growth at the source and rinse clean without any risk of damage.
This tailored approach means every surface on your property gets the specific treatment it needs — no shortcuts, no damage.
The Bottom Line
The right method depends entirely on the surface being cleaned. Concrete can handle high pressure. Everything else should be soft washed. When you hire Splash Pressure Washing, you don't have to worry about which method to choose — we handle that for you.
