Soft-wash house washing. The siding's dirty, not beat up.

Low-pressure application (typically 60–80 PSI at the wall) of a cleaning solution, sodium hypochlorite plus a surfactant that keeps it on the surface long enough to work. The chemistry kills algae, mildew, and gloeocapsa. Then we rinse with clean low-pressure water. No tip of a pressure wand ever touches your siding.

Not if we do it right. We pre-wet every plant bed within overspray range, dilute the mix correctly, and post-rinse the foliage. Soft-wash pros do house washes every day around rose bushes, lemon trees, and Japanese maples. The damage stories come from DIY mixes that skip the pre-wet and use uncut SH.

Pressure washing uses force to blast dirt off. Soft wash uses chemistry to kill and loosen what's there, then a gentle rinse. Concrete and masonry handle high pressure fine. Painted and wood surfaces do not, and stucco cracks from high pressure faster than people realize.

The walls are visibly dry in 30 to 60 minutes depending on sun and humidity. Full cure on any remaining chemistry is a couple hours. You can walk around the house immediately, we rinse everything at ground level.
