Mold growth on outdoor sofa undersides is a common issue, especially in humid or rainy climates. To keep your furniture mold-free, follow these expert tips:

1. Use Waterproof Covers: Invest in high-quality, breathable waterproof covers to shield your sofa from moisture. Ensure the covers fit snugly and are removed periodically to allow ventilation.

2. Elevate the Sofa: Place your sofa on raised legs or a slatted base to improve airflow underneath. This prevents moisture buildup and reduces mold risk.

3. Regular Cleaning: Clean the underside of your sofa monthly with a mixture of mild soap and water. For stubborn mold, use a solution of white vinegar or diluted bleach (1:10 ratio with water).

4. Apply Mold-Resistant Spray: Treat the underside with a commercial mold inhibitor or a natural alternative like tea tree oil spray (1 tsp oil per cup of water).

5. Ensure Proper Ventilation: Position your sofa in a well-ventilated area, avoiding tight spaces or damp corners. If possible, store it indoors during prolonged wet weather.

By following these steps, you can extend the life of your outdoor sofa and enjoy a mold-free seating area year-round.
