Cleaning eifs (synthetic stucco) safely
EIFS looks like stucco but is a foam insulation board with a thin acrylic finish coat. It dents and gouges easily, and water forced behind it is a well-known cause of hidden damage, so it is cleaned with low pressure and solution, never blasted.
Avoid: Any high pressure, which can tear the finish coat or drive water into the wall system.
How often: Every 1-2 years.

Serving Alpine, CA and nearby towns
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.
