Sounds like one of those “too easy to be true” cleaning hacks.
What’s the actual trick your neighbor showed you? You didn’t include the steps after “Here’s how it works,” so I’m missing the key part.
If you’re trying to describe the common low-effort method people use for green algae on siding, it’s usually something like:
- Spray on a diluted bleach solution or oxygen-based cleaner
- Let it sit (no scrubbing)
- Rinse later with a hose or let rain wash it off
But there are a few different versions depending on what they used (bleach, vinegar mix, or a commercial “spray-and-leave” product).
Share the exact steps your neighbor gave you, and I’ll tell you if it’s actually safe, effective, or just a viral myth.
