The secret to house washing for vinyl siding is using the right method, not the most pressure. In Maryland, we match the cleaner and pressure to the surface so it comes out clean without damage. With vinyl siding, the right approach is soft wash.
How we clean it
Cleaning solution: A diluted sodium hypochlorite (house wash) mix with a surfactant, applied low and rinsed thoroughly.
Cleaning vinyl siding safely
Vinyl is the most common siding in the U.S. and cleans up well, but the panels overlap. Water driven upward under the laps can soak the sheathing behind them, so siding is rinsed at a downward angle and never blasted from below.
Avoid: High pressure aimed up under the panel laps, and hot water on dark-colored vinyl, which can warp.
How often: Every 1-2 years, more often on shaded north walls.

Local house washing for vinyl siding for Maryland
Humid summers in Maryland grow green algae and black mildew on the shaded sides of homes, especially on vinyl and painted wood. A soft wash kills the growth rather than just knocking it off, so the siding stays clean longer.
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.

We pre-wet plants and lawns, keep cleaning solutions diluted to what the surface needs, and rinse landscaping again when we finish. Keep pets and children inside until surfaces are rinsed and dry.
How often should I schedule house washing for vinyl siding?
