How do you prevent algae growth on shaded marble outdoor bar stools?

Algae growth on shaded marble outdoor bar stools can be unsightly and slippery, posing a safety hazard. To prevent algae, follow these steps:

1. Regular Cleaning: Wash the stools with a mixture of mild soap and water weekly 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 (1:10 ratio with water), scrub gently, and rinse thoroughly.

3. Improve Airflow: Trim nearby plants or rearrange furniture to allow more sunlight and airflow, reducing damp conditions.

4. Apply Sealant: Use a marble-safe sealant to create a protective barrier against moisture and algae.

5. Cover When Not in Use: Protect stools with waterproof covers during rainy seasons to minimize exposure to moisture.

By maintaining cleanliness and reducing shade and moisture, you can keep your marble bar stools algae-free and pristine.
