Soft Washing vs. Pressure Washing: Which Is Right for Your House?

These two terms get used interchangeably, but they're different processes suited to different jobs. Knowing the difference can save your siding from damage.

What is pressure washing?

Pressure washing uses high water pressure to physically blast away dirt and grime. It's effective for hard, durable surfaces like concrete driveways and sidewalks.

What is soft washing?

Soft washing uses low water pressure combined with a specialized cleaning solution to break down algae, mildew, and dirt at the source, then rinses it away gently. This is the standard for house siding, roofs, and other delicate surfaces.

Why siding needs soft washing, not pressure washing

• High pressure can force water behind siding panels, leading to hidden moisture damage

• It can strip paint and damage the surface finish

• It doesn't kill the algae or mildew at the root, so growth returns faster

The right tool for the right surface

A professional exterior cleaning company will use soft washing for your house and pressure washing for your driveway, deck, or concrete — matching the method to the material.
