Phototrophic growth, such as algae and moss, can quickly turn outdoor seating into a slippery and unsightly mess. To maintain clean and safe outdoor furniture, consider these proven strategies:

1. Use UV-Resistant Materials: Opt for seating made from UV-stabilized plastics, metals, or treated wood, which resist moisture and inhibit algae formation.

2. Install Shade Solutions: Canopies, umbrellas, or pergolas reduce direct sunlight and moisture retention, slowing phototrophic growth.

3. Apply Protective Coatings: Anti-microbial or water-repellent sealants create a barrier against algae and mold.

4. Regular Cleaning: Frequently scrub surfaces with a mix of vinegar or mild bleach to remove early growth before it spreads.

5. Ensure Proper Drainage: Elevate seating or use sloped designs to prevent water pooling, a key factor in algae development.

By combining these methods, you can keep outdoor seating pristine and extend its lifespan.
