The secret to pre-paint washing for stucco is using the right method, not the most pressure. In Yakima, WA, we match the cleaner and pressure to the surface so it comes out clean without damage. On stucco, the method we use is 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.

Pre-Paint Washing for Stucco in Yakima, WA
Green algae on siding is very common in Washington, especially on north walls and under trees. A soft wash kills it, and keeping plants trimmed back helps the walls dry between rains.
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.
