Pressure Washing vs. Soft Washing: What Your Conway Home Actually Needs
Pressure Washing vs. Soft Washing: What Your Conway Home Actually Needs
If you've searched around Conway or Horry County for exterior cleaning, you've probably seen both terms thrown around like they mean the same thing.
They don't — and using the wrong one on the wrong surface can actually damage your home.
Here's the real difference, and how to know which one your house needs.
The short version
Pressure washing: uses high-powered water alone to blast dirt, oil, and grime off tough, durable surfaces like concrete and pavers.
Soft washing: uses low pressure combined with a specialized cleaning solution to lift algae, mold, and mildew off more delicate surfaces like vinyl siding, stucco, and roof shingles — without the force that can strip paint or force water behind your siding.
The surface determines the method. Get it backwards, and you risk cracked caulking, stripped paint, or water intrusion that costs a lot more to fix than the cleaning itself.
When pressure washing is the right call
High pressure is built for surfaces that can take the impact:
Driveways and walkways — concrete and pavers handle pressure well, and it's often the only thing that lifts embedded oil stains and tire marks.
Surface cleaning a driveway Patios and pool decks — same logic, especially concrete that's gone gray or slick over time.
Pool pressure washing Some brick surfaces — brick is tough enough for moderate pressure in most cases.

If it's flat, hard, and outdoors, pressure washing is usually the right tool.
When soft washing is the right call
Soft washing exists because not every surface can handle a blast of high-pressure water:
Vinyl, wood, or stucco siding — high pressure can force water behind panels, leading to mold growth you can't see until it's a real problem.
Vinyl siding Roof shingles — those black streaks aren't dirt, they're algae feeding on the shingle material. Pressure washing a roof can actually strip granules and shorten its lifespan. Soft washing kills the algae at the root without touching the shingles aggressively.
Painted surfaces — trim, fascia, and painted wood siding can lose paint under high pressure.
In Conway's humidity, this is the more common need. That green and gray buildup on siding is almost always some mix of algae, mold, and mildew — soft washing is what actually kills it instead of just knocking the surface layer off (which lets it grow back faster).
How often does each one need to happen?
Soft washing (siding/roof): Once a year is typically enough for most Horry County homes, given how quickly humidity brings growth back.
Pressure washing (driveways/patios): Every 1–2 years, or sooner if you're noticing oil stains or slick spots after rain.

Signs you need one now
Green or black streaks spreading across siding → soft wash
Black streaks running down roof shingles → soft wash
Concrete that's gone from gray to almost black, or feels slick when wet → pressure wash
Oil stains or tire marks on the driveway → pressure wash
The bottom line
If you're not sure which one your home needs, the safest move is to have someone look at it before booking — using the wrong method on the wrong surface is how homeowners end up with damage instead of a clean house.
