Soft Washing for Stone & Stone Veneer in Mountain View, CA
In California, stucco and siding mostly collect dust, cobwebs and sprinkler spots, while shaded walls can grow mildew after winter rains. A soft wash handles both without etching stucco.
Near the coast, salt air leaves a film on siding, windows, screens and railings that dulls finishes and speeds up corrosion on metal. Regular rinsing and washing help protect them.
Much of California has hard water. Sprinklers and misters leave white mineral spots on walls, windows, fences and pool tile, and those spots need a mineral-safe cleaner, not more pressure.
Some cities in California limit outdoor water use, including washing hard surfaces with a hose, especially during drought declarations. Pressure washers use far less water than an open garden hose, but rules vary, so it's worth checking your city's current restrictions. Wash water should also be kept out of storm drains.
