Ah, that’s a classic “easy-clean” trick many homeowners love! Green algae on siding can be stubborn, but there’s a surprisingly simple and low-effort method to get rid of it:
The Trick: Baking Soda or Vinegar Spray
- Choose Your Cleaner:
- Baking Soda Method: Mix 1 cup of baking soda with 1 gallon of water.
- Vinegar Method: Mix equal parts white vinegar and water.
- Apply to Algae:
- Pour the solution into a garden sprayer or a spray bottle.
- Spray generously over the siding covered in green algae.
- Let It Sit:
- Allow it to sit for 15–20 minutes. The solution loosens the algae and kills it naturally.
- Rinse (Optional):
- For mild cases, sometimes no scrubbing is needed—just let rain or a garden hose rinse it away.
- For stubborn patches, lightly scrub with a soft brush.
Why It Works
- Baking soda is mildly abrasive and raises the pH, which makes it hard for algae to survive.
- Vinegar is acidic, which also kills algae and prevents regrowth.
- Both methods are non-toxic and safe for most plants and pets.
💡 Pro Tip: Spray on a cloudy day or when siding is cool to prevent streaks and maximize effectiveness.
If you want, I can share a “no-scrub, zero-effort” version using just household items you probably already have, which makes siding look almost brand new in minutes.
Do you want me to show that?
