Wahoo Washing
People use "power washing," "pressure washing," and "soft washing" like they're interchangeable, but they describe two different methods, and picking the wrong one for a surface can do more harm than good.
Pressure washing relies on high water pressure, sometimes in the thousands of PSI, to physically blast dirt, grime, and buildup off a hard surface. It works well on concrete driveways, sidewalks, pavers, and other surfaces that can handle that kind of force without being damaged.
Soft washing relies on lower water pressure combined with a cleaning solution that does the actual work of breaking down mold, algae, and mildew. Instead of blasting the growth off, the solution kills it at the surface and the low-pressure rinse washes it away. This is the method we use on house siding, stucco, and roofing, where high pressure could strip paint, force water behind panels, or loosen shingles.
Why the distinction matters
The short version: pressure is for tough, hard surfaces, and chemistry is for delicate ones. If you use pressure washing on siding, you risk stripping paint, driving water into places it shouldn't go, or damaging softer materials like wood and vinyl. If you use soft washing on a driveway with years of built-up grime, you might not get enough physical force to actually lift it.
A good rule of thumb: if a surface is something you could scratch with a fingernail or dent with a firm push, like siding or shingles, it's a soft-wash surface. If it's something you'd need a chisel to damage, like poured concrete, it can usually handle pressure washing.
What we clean with each method
We use pressure washing for driveways, walkways, patios, and other hard, flat surfaces built to take direct force.
We use soft washing for house siding, stucco, fences, and any surface where mold or algae growth is the problem rather than embedded dirt.

The method matters more than the marketing term. If a company offers to "power wash" your house without asking what the siding is made of, that's worth a second thought. We look at the surface first and choose the method that gets it clean without putting it at risk.
