Vinyl siding is low-maintenance—but it’s not no-maintenance. Over time, dirt, mold, mildew, and even insect residue can build up. Here’s how to safely clean your siding and keep your home looking its best.

1. Start with a Visual Inspection

Before you grab the hose, take a walk around your home:

• Look for cracks, gaps, or loose panels

• Check for signs of mildew or algae growth

• Note any spots that may need extra attention

🛠️ Fix loose panels before cleaning to avoid water getting behind the siding.

2. Use the Right Cleaning Solution

For general dirt:

• Mix 1/3 cup of laundry detergent with 1 gallon of water

For mildew or mold:

• Add 1 quart of white vinegar to the mix

🚫 Avoid harsh chemicals like undiluted bleach or abrasive cleaners—they can damage vinyl’s finish.

3. Choose Your Tools Wisely

Use:

• A soft-bristle brush on an extension pole

• A garden hose with a spray nozzle

• Optional: a pressure washer on low setting only

⚠️ Always spray downward, not upward, to prevent water intrusion behind panels.

4. Work in Sections

Start at the bottom and work your way up:

1. Wet the siding

2. Scrub with your solution

3. Rinse thoroughly before it dries

⏱️ Don’t let soap or vinegar dry on the surface—it can leave streaks.

5. How Often Should You Clean It?

Most homes benefit from a full clean once a year, ideally in spring or fall. Shadier areas may need touch-ups more often.

📸 Bonus: Take a before-and-after photo—you might be surprised how much brighter your siding looks.
