Black spots on your outdoor table are often caused by mold, mildew, or algae due to moisture and lack of proper maintenance. Here’s how to prevent and remove them effectively:

1. Regular Cleaning: Wipe your table with a mild soap and water solution weekly to remove dirt and prevent mold growth.

2. Dry Thoroughly: After cleaning or rain, dry the table completely to avoid moisture buildup.

3. Use Protective Covers: Cover your table when not in use to shield it from rain and humidity.

4. Apply Vinegar or Bleach Solution: For existing black spots, mix equal parts water and white vinegar or a diluted bleach solution (1:10 ratio) to scrub the affected areas.

5. Seal Wooden Tables: If your table is wooden, apply a sealant annually to protect it from moisture and mold.

By following these steps, you can keep your outdoor table spot-free and extend its lifespan. Regular maintenance is key to preventing black spots and ensuring your furniture stays in great condition.
