That headline is another example of a clickbait teaser. If the claim is that there’s a “0 effort” way to remove green algae from house siding, the reality is more modest: algae can often be cleaned effectively, but there isn’t a method that requires no work.
A common and effective approach is:
- Mix 1 part household bleach with 3–4 parts water (some people add a small amount of dish soap to help it cling).
- Wet nearby plants with plain water first and protect them if possible.
- Apply the solution to the siding and let it sit for 5–10 minutes.
- Gently scrub stubborn areas with a soft brush if needed.
- Rinse thoroughly with water.
Alternatively, there are commercial exterior cleaners designed for algae and mildew.
A few precautions:
- Never mix bleach with ammonia, vinegar, or other cleaners, as this can produce dangerous gases.
- Avoid using a pressure washer at high pressure on vinyl siding, since it can force water behind the panels or damage the surface.
- Wear gloves and eye protection when working with bleach solutions.
If you can paste the rest of the article, I can tell you whether its “trick” is genuinely effective or just a marketing claim.
