Pre-Paint Washing for Fiber Cement Siding in Spokane Valley, WA
Green algae on siding is very common in Washington, especially on north walls and under trees. A soft wash kills it, and keeping plants trimmed back helps the walls dry between rains.
Near the coast, salt air leaves a film on siding, windows, screens and railings that dulls finishes and speeds up corrosion on metal. Regular rinsing and washing help protect them.
