Soft Washing in Spokane
Low-pressure exterior cleaning that safely removes algae, mildew, and organic buildup.
Not every surface can handle high-pressure cleaning. Vinyl siding, stucco, painted wood, and roofing can all be damaged by a standard pressure washer — cracked panels, stripped paint, and voided shingle warranties are common results of the wrong approach.
Soft washing solves this. Instead of raw pressure, our Spokane soft washing crew applies specialized cleaning solutions at low pressure that break down algae, mold, mildew, and organic staining at the root, then gently rinses it all away.
The result is a deeper, longer-lasting clean that's completely safe for your Spokane home's most delicate exterior surfaces — and for the landscaping around them. Pair soft washing with exterior window cleaning for a complete curb appeal reset in a single visit.

Soft Washing vs. Pressure Washing: Which One Does Your Home Need?
Simple rule: hard mineral surfaces get pressure; everything organic-stained or delicate gets soft washed. Concrete driveways and stone patios love high pressure. Vinyl siding, stucco, cedar, painted wood, and asphalt shingles don't — high pressure cracks panels, strips paint, voids shingle warranties, and drives water behind siding.
Soft washing flips the equation: instead of force, it uses a treatment solution applied at garden-hose pressure that kills algae, mold, and mildew at the root, then rinses clean. Most full exterior refreshes in Spokane actually combine both — pressure washing for the flatwork, soft washing for the house.
The Green Streak Problem on Spokane Siding
Those green streaks creeping up north-facing vinyl all over Spokane? That's living algae, not dirt — and it's why scrubbing or pressure-blasting it off never lasts. The surface layer disappears, the organism stays, and it's back within months.
Because soft washing kills growth at the root, the clean holds two to three times longer. It's the difference between mowing a weed and pulling it.

The Best Time to Soft Wash in Spokane

Soft Washing FAQs
What is the difference between soft washing and pressure washing?
Pressure washing uses high-pressure water to physically blast away grime — great for concrete. Soft washing uses specialized cleaning solutions at low pressure to dissolve organic growth — ideal for siding, stucco, and roofs.
Is soft washing safe for my roof?
Yes. Soft washing is the method recommended by shingle manufacturers. High-pressure washing can strip granules and void your warranty; soft washing cleans without any of that risk.
Will the cleaning solutions harm my plants?
No. We pre-rinse and protect your landscaping before applying anything, and our solutions are biodegradable and diluted to be plant-safe.
How long do soft washing results last?
Because soft washing kills algae and mold at the root rather than just removing the surface layer, results typically last 2–3 times longer than pressure washing alone.
What surfaces should be soft washed instead of pressure washed?
Vinyl siding, stucco, painted wood, cedar, roofs, screens, and outdoor furniture should all be soft washed. Concrete and stone do great with standard pressure washing.
Is soft washing safe for painted surfaces?
Yes — that's exactly what it's for. The pressure is comparable to a garden hose, so paint, stain, and delicate trim are never at risk the way they are under a pressure washer.
How quickly will I see results?
Dirt and most algae rinse away immediately. Heavier organic staining (like black roof streaks) keeps improving for days after treatment as the solution finishes killing the growth and weather carries it away.
How often does a house need soft washing?
Every 2–3 years for most Spokane homes. North-facing walls and heavily shaded properties may want a touch-up sooner, since algae regrows fastest where the sun doesn't reach.
