How to prevent algae from forming on shaded granite outdoor chairs?

Granite outdoor chairs are durable and stylish, but when placed in shaded areas, they can become prone to algae growth due to moisture and lack of sunlight. Here are some effective ways to prevent and remove algae:

1. Regular Cleaning – Wash the chairs weekly with a mixture of mild soap and water to remove dirt and moisture that algae thrive on.

2. Use Vinegar or Bleach Solution – For stubborn algae, apply a diluted vinegar or bleach solution (1 part bleach to 10 parts water), scrub gently, and rinse thoroughly.

3. Improve Airflow – Rearrange furniture occasionally to allow better air circulation and reduce dampness.

4. Apply a Sealant – Use a granite-safe sealant to create a protective barrier against moisture and algae buildup.

5. Keep the Area Dry – Wipe down chairs after rain or dew to minimize lingering moisture.

By following these steps, you can keep your granite outdoor chairs algae-free and maintain their aesthetic appeal for years.
