Have you ever looked at the outside of your house and noticed those annoying green streaks and patches appearing on the siding?

They can make an otherwise clean home look neglected. The good news is that you often don’t need to spend hours scrubbing every panel.

With the right exterior cleaner and a little patience, much of the work can be done by the cleaning solution itself.

🌿 Why Does Green Algae Appear on House Siding?

Green algae, mildew and other organic growth tend to appear where surfaces stay damp for long periods.

Common problem areas include:

• Shaded walls
• North-facing siding
• Areas beneath trees
• Places near gutters and downspouts
• Siding that receives little direct sunlight
• Areas where water regularly splashes against the house

Moisture and limited sunlight create favorable conditions for algae and mildew to develop.
