From the free quote to the final rinse, soft washing for wood siding in King of Prussia, PA follows a simple process: inspect, protect, clean, rinse and check. On wood siding, the method we use is soft wash.
How we clean it
Cleaning solution: A mild house-wash mix; an oxygen-based cleaner when the wood will be stained.
Caring for wood siding
Painted and stained wood siding grows mildew and loses its finish faster on the shaded and weather-facing sides. A soft wash cleans it without raising the grain, and is the usual first step before repainting or restaining.
Avoid: High pressure that raises fibers, gouges the wood or strips sound paint unevenly.
How often: Every 1-2 years, and before every repaint.
