House Siding Wash
Soft-wash that lifts a winter of algae off your siding without etching the paint.
Pressure-only washing can force water behind your siding and damage the surface. Soft-wash is the approach siding manufacturers recommend. The chemistry does the work, not high PSI.
Algae, mildew, and pollen build up fast in the Pacific Northwest's wet season. We use a low-pressure soft-wash with a sodium-hypochlorite cleaning solution that kills organic growth at the root, then rinse from the eaves down. Safe on cedar, LP, Hardie, vinyl, and brick.

Will this damage my siding or paint?
No. Soft-wash runs under 500 PSI — closer to a strong garden hose than a pressure washer. The cleaner does the lifting, not the water.
How long does it last?
Soft-washed siding in the Pacific Northwest typically stays clean for 18–30 months. North-facing walls under tree cover come back faster than sunny exposures.
