“Power washing” gets used for everything, but there are really two very different ways to clean the outside of a home. Choosing the wrong one can strip paint, force water behind siding or leave mildew that comes right back. Here is how pressure washing and soft washing differ, and which one your Michigan home actually needs.
What Is Pressure Washing?
Pressure washing uses a high-pressure stream of water, often 2,500 to 4,000 PSI, to blast away dirt and stains. It is the right tool for hard, durable surfaces like concrete driveways, sidewalks, brick pavers and some masonry. It removes ground-in dirt, gum, salt residue and surface stains quickly.
What Is Soft Washing?
Soft washing uses low pressure, about the same as a garden hose, combined with a cleaning solution that kills algae, mildew, mold and bacteria at the root. The solution does the work, not the pressure. It is the method recommended for vinyl siding, painted wood, stucco and asphalt shingle roofs.
Which Is Right for Your Siding?
- Vinyl siding: Soft wash. High pressure can crack panels and drive water behind them.
- Painted wood or fiber cement: Soft wash. Pressure can peel paint and gouge wood.
- Brick: Usually soft wash, with low-pressure rinsing. Old mortar can be damaged by high pressure.
- Roofs: Always soft wash. See roof cleaning and moss removal.
- Decks and fences: Low pressure with wood-safe cleaners. See deck restoration.
- Driveways and sidewalks: Pressure washing with a surface cleaner.
Why Soft Washing Lasts Longer
Pressure alone knocks off the visible green and black growth but leaves the roots behind, so it returns within months. Soft washing kills the organisms, which is why homes stay clean for a year or more, even on shady, north-facing walls common in Southwest Michigan.
The Bottom Line
Most homes need both: soft washing for siding and roofs, pressure washing for concrete. A professional crew uses the right method on each surface.
