Green algae growth on outdoor tables is a common issue, especially in humid or shaded areas. To prevent this, follow these practical tips:

1. Regular Cleaning: Wipe your table weekly with a mild soap solution to remove dirt and moisture that algae thrive on.

2. Proper Drying: After rain or cleaning, dry the surface thoroughly to eliminate dampness.

3. Use Protective Covers: When not in use, cover your table with a waterproof cover to shield it from moisture and debris.

4. Apply Vinegar or Bleach Solution: For stubborn algae, mix equal parts water and white vinegar (or a diluted bleach solution) and scrub the affected area. Rinse well afterward.

5. Ensure Good Airflow: Place your table in a sunny, well-ventilated spot to reduce humidity buildup.

By adopting these habits, you can keep your outdoor table algae-free and extend its lifespan. For persistent problems, consider using commercial algae-resistant coatings designed for outdoor furniture.
