The difference
Pressure washing uses high pressure water to blast dirt off hard surfaces. Soft washing uses low pressure, about what a garden hose puts out, combined with a cleaning solution that breaks down mildew, algae and organic growth so it rinses away.
Pressure removes what is on the surface. Soft washing treats the growth itself, which is why results on siding and roofs usually last longer.
Which surfaces get which
| Surface | Method |
|---|---|
| Vinyl, Hardie and painted siding | Soft wash |
| Asphalt shingle roofs | Soft wash only, no pressure |
| Stucco and painted masonry | Soft wash |
| Concrete driveways and sidewalks | Pressure wash with a surface cleaner |
| Pavers and brick | Moderate pressure |
| Wood decks and fences | Low pressure with the right cleaner |
What goes wrong with the wrong method
- High pressure on siding can force water behind panels and into walls.
- Pressure on a roof can strip the granules that protect shingles.
- Too much pressure on wood raises the grain and leaves a fuzzy, splintered surface.
- A wand held too close to concrete can leave permanent stripes and etching.
How to choose a company
Ask how they will clean each surface. A good company soft washes siding and roofs, uses surface cleaners on concrete, and adjusts pressure for wood and pavers. Make sure they are licensed and insured, and read their reviews.

Frequently asked questions
Is soft washing just a gentler pressure wash?
Not exactly. The cleaning solution does most of the work in a soft wash, and the low pressure rinse simply carries the growth away.
Can I pressure wash my own house?
You can, but high pressure on siding is risky. Soft washing is the safer method for most home exteriors.
