How do you remove mildew stains from canvas outdoor sofa cushions?

Mildew stains on canvas outdoor sofa cushions can be unsightly and difficult to remove, but with the right approach, you can restore them to their original condition. Here’s a step-by-step guide to effectively eliminate mildew:

1. Brush Off Loose Mold: Start by brushing away any loose mildew spores outdoors to prevent spreading. Use a soft-bristle brush and wear gloves for protection.

2. Prepare a Cleaning Solution: Mix equal parts white vinegar and water in a spray bottle. Vinegar is a natural antifungal agent that kills mildew. Alternatively, use a mild detergent mixed with warm water.

3. Apply the Solution: Spray or dab the solution onto the stained areas. Let it sit for 10-15 minutes to penetrate the mildew.

4. Scrub Gently: Use a soft brush or sponge to scrub the stains in circular motions. Avoid harsh scrubbing to prevent damaging the canvas fabric.

5. Rinse Thoroughly: Rinse the cushions with clean water using a hose or damp cloth. Ensure all cleaning residue is removed to prevent attracting more dirt.

6. Dry Completely: Place the cushions in direct sunlight to dry. Sunlight helps kill remaining mildew spores and prevents future growth.

For stubborn stains, repeat the process or use a specialized mildew remover. Regular cleaning and proper storage can prevent mildew from recurring. Keep cushions dry and store them in a well-ventilated area when not in use.

By following these steps, your canvas outdoor sofa cushions will look fresh and mildew-free, extending their durability for seasons to come.
