Vinyl siding is low maintenance, but it's not no maintenance. Over time it collects dust, pollen, cobwebs and green or black mildew, especially on the north side of the house. The good news is that vinyl cleans up easily with water and a little patience.
What You'll Need
- A garden hose with a high pressure nozzle that has adjustable spray patterns
- A soft brush on an extension pole
- A bucket of water with a mild soap (optional)
- Plastic sheeting for delicate plants (optional)
Step 1: Close Everything
Shut windows and doors, and cover outdoor outlets, lights and vents. Water should never be sprayed directly into these openings.
Step 2: Test a Small Area
Start in a low, hidden spot with a gentle setting. You want to clean the surface, not force water behind the panels.
Step 3: Spray From Top to Bottom – and Downward
This is the key rule for siding. Vinyl panels overlap like shingles. If you spray upward, water can get trapped behind them. Always aim the spray at a downward angle and work from the top of the wall to the bottom.
Use a wider spray pattern for general dirt and a more focused one only for stubborn spots, keeping a safe distance.
Step 4: Scrub Mildew Spots
For green or black spots, scrub gently with a soft brush and mild soapy water, then rinse. Avoid abrasive pads – they can dull the finish.
Step 5: Final Rinse
Rinse each section from the top down before soap dries on the surface. Dried soap leaves streaks.
Mistakes to Avoid
- Spraying upward under the panels
- Using the strongest setting on old or brittle siding
- Cleaning in direct, hot sun (soap dries too fast)
- Spraying directly into vents, outlets or light fixtures
How Often to Clean Siding
Once a year is enough for most homes. Shady walls or homes near trees and dirt roads may need a rinse twice a year.

Quick FAQ
Can I clean vinyl siding with a garden hose?
Yes. A hose nozzle with adjustable spray and a soft brush handles most dirt and mildew. Always spray downward.
Is high pressure safe for vinyl siding?
Use a lower setting and keep your distance. Too much pressure, or spraying upward, can push water behind the panels.
