The secret to house washing for eifs (synthetic stucco) is using the right method, not the most pressure. In Illinois, we match the cleaner and pressure to the surface so it comes out clean without damage. On eifs (synthetic stucco), the method we use is soft wash.
Method and pressure
Cleaning solution: A mild, EIFS-safe detergent solution with a gentle rinse.
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.
