Photolithotrophic growth, such as algae and mold, can quickly turn outdoor seating into an unsightly and slippery hazard. To maintain clean and safe patio furniture, follow these proven methods:

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

2. Proper Drainage: Ensure seating areas have adequate drainage to prevent water accumulation, which promotes microbial growth.

3. UV-Resistant Coatings: Apply sealants or UV-resistant paints to create a barrier against moisture and sunlight, which algae and mold thrive on.

4. Shade Management: Use umbrellas or awnings to reduce direct sunlight exposure, slowing photolithotrophic growth.

5. Natural Inhibitors: Sprinkle baking soda or use copper-based solutions, as these substances naturally deter algae and mold.

By implementing these strategies, you can keep your outdoor seating clean, durable, and free from unwanted biological growth.
