Your fence looks like this? Don’t replace it yet!
If your fence, siding, or patio furniture is covered in this green algae or fungus, you might be able to clean it instead of replacing it.
Here’s what I used: pool bleach, water, and a surfactant.
The surfactant helps the solution stick to the surface longer, so it can actually do its job.
And yes… it was raining while I was doing this. 😂
Before spraying, I soaked the grass really well with water because bleach can damage or kill your grass.
Then, apply the solution and let it sit for about 5 to 10 minutes.
Don’t let it dry.
If it’s still dirty, apply it again.
And now… look at this!
That is a completely different fence.
So before you spend thousands replacing your fence or siding, try cleaning it first.
Just be careful with bleach, protect your plants and grass, and always use the proper dilution and safety precautions.
