From the free quote to the final rinse, exterior mold & mildew removal for wood siding in Evansville, IN 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.
What to know about cleaning 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.
