Soft Washing vs Pressure Washing: What Your Siding Actually Needs

People use "pressure washing" and "power washing" to mean any kind of outdoor cleaning with water. But there are really two different methods, and using the wrong one on your house can do more harm than good. One blasts dirt off with force. The other lets cleaning solution do the work at low pressure.

Here's the plain difference, and how to tell which one each part of your property needs.

What pressure washing is

Pressure washing uses a machine that pushes water out of a narrow tip at high pressure, often 3,000 PSI or more. It's the right tool for hard, durable surfaces where dirt and stains are ground in.

• Concrete driveways and sidewalks
• Patios and pool decks
• Brick walkways and pavers
• Trash can pads

On those surfaces, high pressure with a surface cleaner gives an even, clean result. That's how our driveway and patio cleaning works.

What soft washing is

Soft washing uses low pressure, about what comes out of a garden hose, combined with a cleaning solution that breaks down mildew, algae, and dirt. The solution does the heavy lifting. Then it's rinsed off gently.

The big advantage is that soft washing kills the growth at the root instead of just knocking off the top layer. That means your siding stays clean longer.

Why high pressure is rough on siding

Vinyl siding is made of overlapping panels. Hit it with high pressure from the wrong angle and you force water up behind the panels, where it can soak the wall and grow mold where you can't see it. You can also crack older vinyl, strip paint, etch wood, and blow out window seals.

Brick and mortar can take more, but high pressure can still damage older mortar joints. Painted surfaces and wood trim are the most delicate of all.

What your siding actually needs

For almost every house in DeSoto County, the answer is soft washing for the house itself and pressure washing for the concrete around it.

• Vinyl siding: soft wash
• Painted wood or fiber cement: soft wash
• Brick: soft wash, with low pressure rinse
• Gutters (outside face): soft wash to remove black streaks
• Driveways, sidewalks, patios: pressure wash with a surface cleaner
• Wood decks and fences: low pressure with the right cleaner

How long does a soft wash last?

Because soft washing kills the mildew and algae instead of just spraying it off, results last much longer. In our humid climate most homes look good for one to two years before the green starts creeping back, especially on the north side or under trees. We explain why that happens in why siding turns green in Mississippi.

Is soft washing safe for plants and pets?

When it's done right, yes. A careful crew wets down plants before and after, mixes solution to the right strength for the surface, and rinses thoroughly. Keep pets inside while the work is happening and for a little while after so everything has time to dry.

Doing it yourself

A rented pressure washer is fine for a small patio if you keep the tip moving and stay back from the surface. For the house itself, we'd steer you away from renting a machine and climbing a ladder with it. Most siding damage we see comes from a well-meaning weekend with a borrowed washer.
