Spray Wash cleaned the exterior of this parking deck on June 1. The exterior is an exposed aggregate limestone, which makes it very difficult to clean ( and nearly impossible to pressure wash!) Due to the aggregate, each square inch of surface has about 15 different "faces" and angles to hit. We cleaned the exterior with a 2% mixture, rinsed, reapplied, and then rinsed again. Later this week we will be attacking the graffiti with "Worlds Best Graffiti Remover".
One day project, no pressure washer was used.
Feel free to call/email with questions.
