If your patio gets zero sun, you are right to be concerned about mildew on your outdoor furniture cushions. The lack of direct sunlight creates a damp, cool environment where mildew and mold thrive. This is a common challenge for urban outdoor spaces like balconies and shaded patios.
Mildew is a type of mold that grows on organic materials, such as the fabric of your cushions, when moisture is present. Without the sun's natural drying and disinfecting power, any moisture from rain, humidity, or even morning dew lingers much longer, significantly increasing the risk of mildew growth. The problem can be exacerbated if debris like leaves accumulates on the cushions, trapping more moisture.
However, mildew is not an inevitable fate. You can take several proactive steps to prevent it:
1. Choose the Right Cushions: Opt for quick-drying, mildew-resistant cushions made from solution-dyed acrylic or polyester fabrics. These materials are designed to shed water and resist microbial growth.
2. Improve Airflow: Arrange your furniture to allow for maximum air circulation. Avoid pushing furniture directly against walls.
3. Remove Moisture Promptly: After a rain shower or if you notice condensation, wipe down your cushions with a dry towel. This simple step removes the moisture mildew needs to grow.
4. Proper Storage: When not in use for extended periods, or during consistently wet weather, store your cushions in a dry, well-ventilated area. A storage bench is a perfect solution for urban settings.
5. Regular Cleaning: Establish a routine of cleaning your cushions with a mild soap and water solution. This removes the dirt and organic matter that mildew feeds on.
If you do spot mildew, act quickly. Create a cleaning solution of one part white vinegar to one part water, or a diluted bleach solution (follow manufacturer guidelines carefully). Scrub the affected area with a soft brush, allow it to sit for 10 minutes, and then rinse thoroughly. Ensure the cushion is completely dry before using it again.
In conclusion, while a sunless patio does create a high risk for mildew, it is a manageable problem. By selecting appropriate furniture and implementing a consistent maintenance routine of drying and cleaning, you can keep your cushions looking fresh and mildew-free all season long.
