Why is Green Algae Important?

While green algae may seem like an unwelcome presence on surfaces, it plays a crucial role in the ecosystem. As photosynthetic organisms, green algae are responsible for producing oxygen and capturing carbon dioxide, contributing to the planet’s overall carbon cycle. Additionally, they serve as a vital food source for various aquatic organisms, supporting the biodiversity of ecosystems.

How Does Green Algae Work?

Green algae grow and spread through spores, which are tiny reproductive cells. These spores can be carried through the air and water, allowing green algae to colonize surfaces like roofs, decks, and sidings. Once settled, green algae start to photosynthesize, using sunlight and carbon dioxide to produce energy and grow, eventually forming visible green patches.

What Are the Benefits of Green Algae in Pressure Washing?

When it comes to pressure washing, green algae can be both a friend and a foe. The benefits of green algae in pressure washing include:

  • Natural Cleaning Power: Green algae can help break down organic matter and stains, making it easier for pressure washing equipment to remove dirt and grime from surfaces.
  • Eco-Friendly Solution: Since green algae is a natural organism, using it as a cleaning agent is environmentally friendly compared to harsh chemicals that may harm aquatic life and plants.
  • Effective Pre-Treatment: In pressure washing, green algae can serve as a pre-treatment step, softening tough stains and preparing the surface for a thorough cleaning.

Are There Any Downsides to Green Algae in Pressure Washing?

While green algae can aid in the cleaning process, there are some downsides to consider:

Incomplete Cleaning

Green algae might not fully remove all stains and grime, leading to the need for additional cleaning or manual scrubbing.

Re-Growth Potential

If not entirely eliminated, green algae can quickly re-colonize surfaces, requiring more frequent cleaning.


Pressure washing with green algae as a pre-treatment may require a longer dwell time to achieve satisfactory results.
