Red-clay dust bakes into concrete; hot-water surface cleaner lifts it in one pass. East County homes get a yearly coating of granite dust and wildfire smoke residue.

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.
