What are the best ways to remove mildew stains from synthetic rattan outdoor armchairs?

Mildew stains on synthetic rattan outdoor armchairs can be unsightly and difficult to remove if not treated properly. Here are the best ways to clean and prevent mildew buildup:

1. Vinegar Solution: Mix equal parts white vinegar and water in a spray bottle. Spray the affected areas and scrub gently with a soft brush. Rinse with clean water and let it dry.

2. Baking Soda Paste: Create a paste using baking soda and water. Apply it to the mildew stains, let it sit for 15-20 minutes, then scrub and rinse thoroughly.

3. Mild Soap and Water: Use a mild dish soap mixed with warm water. Scrub the stains with a soft cloth or sponge, then rinse well.

4. Bleach Solution (for tough stains): For stubborn mildew, dilute 1 part bleach with 10 parts water. Apply carefully, avoiding overuse, and rinse immediately after scrubbing.

5. Preventive Measures: Keep your synthetic rattan furniture dry and covered when not in use. Regularly clean with a damp cloth to prevent mildew growth.

By following these methods, you can keep your synthetic rattan outdoor armchairs looking fresh and mildew-free.
