Mildew on your outdoor furniture cushions is an unsightly and common problem, especially in urban environments where moisture can linger. Fortunately, cleaning it effectively is straightforward with the right approach. The best method involves using a simple, non-toxic solution.
Start by taking the cushions outside to a well-ventilated area. Brush off any loose dirt or spores with a stiff-bristled brush. For the cleaning solution, a 1:1 ratio of white vinegar and water is highly effective against mildew. Alternatively, you can use a mixture of one cup of bleach with a quarter cup of mild laundry detergent in a gallon of water, but be cautious as bleach can fade colors. Always test any solution on a small, hidden area of the cushion first.
Pour your chosen solution into a spray bottle for easy application. Generously spray the entire surface of the cushion, ensuring the mildew spots are thoroughly saturated. Allow the solution to sit for at least 15-20 minutes to penetrate and kill the mildew.
After soaking, use a soft-bristled scrub brush or a sponge to gently agitate the area, paying close attention to the mildewed spots. Avoid using a brush that is too harsh, as it could damage the fabric.
Once scrubbed, rinse the cushion completely with a garden hose or plenty of clean water until all soap residue is gone. It is crucial to remove all the cleaning solution to prevent attracting more dirt.
The final and most critical step is drying. Mildew thrives in damp conditions. Ensure the cushions dry completely in direct sunlight before placing them back on your furniture. Sunlight is a natural mildew killer. To prevent future mildew growth, store cushions in a dry, well-ventilated area when not in use, especially during humid or rainy weather. Regular cleaning and thorough drying are the best defenses against mildew returning to your urban outdoor oasis.
