Lithotrophic growth, such as algae, moss, and lichen, can quickly turn outdoor seating into a slippery, unsightly mess. Preventing these organisms from taking over requires a combination of proactive measures and regular maintenance. Here are the most effective ways to keep your outdoor seating clean and safe:

1. Regular Cleaning – Use a stiff brush and mild detergent to scrub surfaces weekly. For stubborn growth, a pressure washer (on a low setting) can help remove deep-seated algae.

2. Proper Drainage – Ensure water doesn’t pool on seating surfaces, as moisture encourages lithotrophic growth. Adjust furniture placement or install slight slopes to improve runoff.

3. Natural Inhibitors – Apply vinegar or baking soda solutions to deter growth. These eco-friendly options disrupt microbial activity without harsh chemicals.

4. Sealants and Coatings – Use stone or concrete sealants to create a protective barrier. Reapply every 1-2 years for maximum effectiveness.

5. Sunlight and Airflow – Trim overhanging plants to increase sunlight exposure and improve ventilation, reducing damp conditions where growth thrives.

By following these steps, you can maintain clean, slip-resistant outdoor seating while extending its lifespan. Consistent care is key to preventing lithotrophic growth from becoming a recurring problem.
