Soft Washing for Homes & Siding

A low-pressure, chemical-based clean that lifts mildew, algae and grime from siding without the damage a pressure washer can cause.

Soft Washing

Gentler Than Pressure Washing, Built for Siding

High-pressure washing can strip paint, crack vinyl siding, and force water behind panels where it doesn't belong. Soft washing uses low pressure — typically under 500 PSI, compared to the 1,500–3,000 PSI range used on decks — combined with a specialized cleaning solution that breaks down mildew, algae and grime at the surface, then rinses it away safely without damaging siding, brick, stucco, or trim.

It's also more effective long-term. Pressure washing alone blasts growth off the surface but leaves the roots behind, so mildew and algae often return within months. Soft washing's cleaning solution kills mold and algae at the root, which is why a soft-washed house typically stays cleaner longer than one that's only been pressure washed.

We protect landscaping, outdoor furniture and anything else near the house before we start, and rinse thoroughly when we're done so no cleaning solution is left behind on plants or hardscaping.

Cedar shake and shingle siding needs this approach more than almost any other exterior surface. Shakes are thin, hand-split (or resawn) pieces of cedar, and a pressure washer's direct force will lift and separate their grain, split them along the face, and blast away the wood's natural weathering layer — damage that can't be undone. Cedar shakes are also especially prone to moss, lichen and black algae staining because they hold moisture in their rough, porous surface longer than smooth siding does, particularly on north-facing walls and anywhere shaded by trees. Soft washing's low-pressure chemical solution lifts that growth off the shake surface and kills it at the root without ever forcing water up under the courses or eroding the wood itself, which is exactly why it's become the standard method for cleaning cedar shake and shingle exteriors.

Common Questions

Soft Washing Questions We Hear a Lot

What Southeast Michigan homeowners usually want to know before their first soft wash.

What's actually in the soft-wash solution?
Soft washing uses a specialized, low-pressure cleaning solution designed to break down mildew, algae and organic grime without the force of a pressure washer. We size and apply it to your specific siding material so it cleans effectively without damaging paint, caulking or trim.
Will soft washing kill algae and mildew for good?
Soft washing kills mold, mildew and algae at the root rather than just blasting the visible growth off the surface, so results generally last significantly longer than pressure washing alone — though nothing outdoors stays clean forever in Michigan's climate.
Is soft washing safe for landscaping and pets?
We protect plants, furniture and anything else nearby before we start and rinse thoroughly once the cleaning is done, which keeps runoff to a minimum around landscaping.
How is soft washing different from pressure washing my siding?
Pressure washing relies on force — often 1,500 PSI or more — which can strip paint, crack vinyl, or drive water behind panels. Soft washing uses much lower pressure and lets the cleaning solution do the work, making it the safer choice for most home exteriors.
Can you pressure wash cedar shake siding?
We don't recommend it, and we don't do it. Cedar shakes are thin, hand-split cedar pieces, and direct high pressure can split the face of the shake, lift and separate the grain, and strip away the wood's protective weathered layer — none of which can be repaired short of replacing the shake. Soft washing is the safe method for cedar shake and shingle siding.
Why does my cedar shake siding turn dark or grow moss?
Cedar shakes are porous and hold moisture longer than smooth siding, which makes them prone to moss, lichen and black algae staining — especially on north-facing walls or anywhere shaded by trees. That discoloration is a surface growth issue, not a sign the wood is failing, and a soft wash typically restores the shakes' natural color without damaging them.
