From the free quote to the final rinse, rust stain removal for stucco in Mill Valley, CA follows a simple process: inspect, protect, clean, rinse and check. For stucco, that means soft wash.
Method and pressure
Cleaning solution: A diluted house-wash solution with surfactant, given time to dwell, then a gentle rinse.
Caring for stucco
Traditional stucco is porous and holds moisture, which is why it streaks green and black in humid and shaded spots. Hairline cracks are common, and high pressure can force water into them or break off the finish coat.
Avoid: High pressure, which can etch the texture, blow out patches and push water behind the wall.
How often: Every 1-2 years.
