Mixotrophs, such as algae and lichens, can quickly colonize outdoor seating, leading to unsightly stains and potential damage. To prevent their growth, follow these proven methods:

1. Regular Cleaning: Use a mild detergent and water to scrub surfaces weekly. For stubborn growth, a solution of vinegar or hydrogen peroxide can be effective.

2. Protective Coatings: Apply water-resistant sealants or anti-microbial coatings to create a barrier against mixotrophs.

3. Proper Drainage: Ensure seating surfaces are sloped or designed to avoid water pooling, which encourages mixotroph growth.

4. Sunlight Exposure: Position furniture in areas with ample sunlight, as UV rays naturally inhibit mixotroph development.

5. Storage Solutions: During prolonged wet seasons, cover or store outdoor seating to minimize moisture exposure.

By implementing these strategies, you can maintain clean, durable outdoor seating free from mixotroph infestations.
