You can remove green algae from your house using a few different methods, depending on the severity of the growth.
Here's a breakdown of effective approaches:
1. Mild Algae Growth: Dish Soap and Water
- For light algae accumulation, a simple solution of dish soap and water often does the trick.
- Mix a small amount of dish soap (e.g., 1-2 tablespoons) with a gallon of water.
- Apply the solution to the affected area using a sponge, brush, or cloth.
- Scrub gently to loosen the algae.
- Rinse thoroughly with clean water.
2. Thicker Algae Growth: Powdered Laundry Detergent and Water
- When algae growth is more established, a stronger cleaning agent is required.
- Create a solution using powdered laundry detergent and water. Follow the detergent manufacturer's instructions for dilution strength, but generally, a stronger concentration than for laundry is needed. Start with a small amount and increase until you see results.
- Apply the solution and let it sit for a short period (e.g., 10-15 minutes) to help break down the algae.
- Scrub vigorously with a brush.
- Rinse thoroughly with clean water. Be sure to protect any plants or delicate surfaces from overspray.
3. Heavy Algae Growth: Oxygen Bleach Solution
- For significant algae infestations, oxygen bleach is an effective option. It's also considered more environmentally friendly than chlorine bleach.
- Mix oxygen bleach powder with water according to the product instructions.
- Apply the solution to the affected area using a sprayer or brush.
- Allow it to sit for the recommended time (usually 10-20 minutes).
- Scrub if necessary to remove any remaining algae.
- Rinse thoroughly with clean water.
Important Considerations:
- Safety First: Always wear gloves and eye protection when working with cleaning solutions.
- Test in an Inconspicuous Area: Before applying any solution to a large area, test it on a small, hidden spot to ensure it doesn't damage the surface.
- Pressure Washing: A pressure washer can be effective for removing algae, but use caution, especially on delicate surfaces, as it can cause damage. Start with a low-pressure setting and gradually increase it as needed. Ensure proper runoff to avoid damaging surrounding landscaping.
- Prevention: Address the underlying cause of the algae growth (excess moisture, lack of sunlight, etc.) to prevent future recurrence. Consider trimming back vegetation that blocks sunlight or improving drainage.
- Avoid Chlorine Bleach: While chlorine bleach can kill algae, it can also damage surfaces, harm plants, and is harsher on the environment. Opt for oxygen bleach as a preferable alternative.
By following these steps, you can effectively remove green algae from your house and restore its appearance.
