Here at San Marcos Window and Pressure Washing, we frequently get asked how our team treats stained stone planters and walls around pool areas. The solution is a basic soft wash process:
The Application: We apply a specialized detergent mixed with industrial-strength bleach directly to the stained stone.
The Rinse: After letting the mixture soak in, we use a pressure washer to rinse it away.
The Results: This method removes surface-level dirt and eliminates algae buildup, whether it appears as black spots or slimy green patches.
This chemical treatment rejuvenates the stone, restoring its original milky white appearance and making it look brand new. If your stonework is looking weathered, a professional soft wash is the perfect way to bring it back to life!
