How to prevent biological growth on shaded stone outdoor ottomans?

Shaded stone outdoor ottomans add elegance to any garden or patio, but they are prone to biological growth like mold, algae, and mildew due to moisture and lack of sunlight. Here’s how to keep them clean and protected:

1. Regular Cleaning: Use a mixture of water and mild detergent to scrub the surface monthly. Avoid harsh chemicals that may damage the stone.

2. Apply Sealant: A high-quality stone sealant creates a protective barrier against moisture and spores. Reapply every 1-2 years.

3. Improve Airflow: Trim nearby plants or rearrange furniture to reduce shade and increase ventilation.

4. Use Natural Solutions: Spray diluted vinegar or hydrogen peroxide to kill existing growth without harming the stone.

5. Cover When Not in Use: Use breathable waterproof covers during rainy seasons to minimize moisture buildup.

By following these steps, you can maintain the beauty and durability of your stone ottomans while preventing unsightly biological growth.
