The secret to house washing for stucco is using the right method, not the most pressure. In Mountain Lakes, NJ, 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.
Cleaning stucco safely
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.

House Washing for Stucco in Mountain Lakes, NJ
Humid summers in New Jersey grow green algae and black mildew on the shaded sides of homes, especially on vinyl and painted wood. A soft wash kills the growth rather than just knocking it off, so the siding stays clean longer.
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.
