Heterotrophic growth, such as algae, mold, and mildew, can quickly turn outdoor seating into an unsightly and unhygienic mess. To maintain clean and durable outdoor furniture, follow these proven strategies:

1. Regular Cleaning – Use a mixture of mild soap and water to scrub surfaces weekly. For stubborn growth, a diluted vinegar or bleach solution can be effective.

2. Proper Drainage – Ensure seating materials allow water to drain quickly, preventing stagnant moisture that fosters microbial growth.

3. UV-Resistant Materials – Opt for synthetic fabrics, treated wood, or metal, which resist moisture absorption and UV damage.

4. Protective Covers – Use waterproof covers during rainy seasons or when furniture is not in use to shield against moisture and debris.

5. Natural Preventatives – Apply eco-friendly solutions like tea tree oil or citric acid sprays to inhibit microbial growth without harsh chemicals.

By implementing these methods, you can extend the lifespan of your outdoor seating while keeping it safe and visually appealing.
