How To Remove Mildew From Outdoor Patio Cushions

Outdoor patio cushions are a popular and comfortable addition to any outdoor space. However, they can be susceptible to mildew growth, especially in humid climates or during periods of prolonged dampness. Mildew can create unsightly stains and an unpleasant odor, making the cushions unappealing and potentially harmful to health. Fortunately, with the right cleaning methods, mildew can be effectively removed from outdoor patio cushions, restoring their appearance and freshness.

Step 1: Assess the Severity of the Mildew

Before embarking on any cleaning process, it is crucial to assess the severity of the mildew infestation. Mildew that is still fresh and light in color can often be removed with a simple cleaning solution. However, if the mildew is thick, dark, and has permeated the fabric, more intensive methods may be required.

Step 2: Choose the Right Cleaning Solution

There are several cleaning solutions that can be used to remove mildew from outdoor patio cushions. The choice of solution depends on the type of fabric and the severity of the mildew. Here are some commonly used options:

Bleach Solution: For heavily soiled cushions, a bleach solution can be effective in killing mildew spores. Mix one part bleach with three parts water. Apply the solution to the affected area and let it sit for 10-15 minutes before rinsing thoroughly. However, bleach can fade some fabric colors, so it is important to test it on an inconspicuous area first.
Baking Soda Paste: Baking soda is a natural cleaning agent that can effectively remove mildew. Create a paste by mixing baking soda with water. Apply the paste to the affected area and let it sit for 30 minutes before scrubbing with a brush. Rinse thoroughly with water.
Vinegar Solution: White vinegar is another natural cleaning agent that can kill mildew. Mix equal parts of vinegar and water. Apply the solution to the affected area and let it sit for 30 minutes before rinsing thoroughly with water.
Commercial Mildew Remover: Several commercial mildew removers are available on the market that are specifically designed for cleaning outdoor furniture. These products are often effective in removing mildew and preventing it from returning.

Step 3: Clean the Cushions Thoroughly

Once you have chosen a cleaning solution, follow these steps to clean the cushions effectively:

Prepare the Cushions: Remove any loose dirt or debris from the cushions using a vacuum cleaner with a brush attachment or a soft-bristled brush.
Apply the Cleaning Solution: Apply the chosen cleaning solution evenly to the affected area using a soft cloth or sponge. For heavier stains, you may need to scrub gently with a brush. However, avoid scrubbing too hard as this can damage the fabric.
Let the Solution Sit: Allow the cleaning solution to sit on the cushions for the recommended time (usually 10-30 minutes) to allow the solution to penetrate the fabric and kill the mildew spores.
Rinse Thoroughly: Rinse the cushions thoroughly with clean water to remove any remaining cleaning solution and mildew spores. You can use a garden hose or a bucket of water for this step.

Step 4: Dry the Cushions Completely

After cleaning the cushions, it is essential to dry them completely to prevent mildew from returning. Ideally, cushions should be dried in direct sunlight for several hours. If this is not possible, you can use a fan to circulate air around the cushions or hang them on a clothesline to air dry. Avoid using a dryer on the cushions as the high heat can damage the fabric.

Step 5: Prevent Mildew Growth

Once the cushions are completely dry, it is important to take steps to prevent mildew from returning. Here are some helpful tips:

Store Cushions Properly: Store cushions in a dry, well-ventilated area when not in use. Avoid storing them in damp basements or garages. You can consider using a waterproof storage bin to further protect the cushions from moisture.
Regularly Clean Cushions: Clean the cushions regularly, even if they do not appear to have mildew. This will help to remove dirt and debris that can attract mildew spores.
Use a Mildew-Resistant Fabric: When purchasing new cushions, consider choosing cushions made from mildew-resistant fabrics, such as Sunbrella or Olefin.
