Mildew stains on a stone composite outdoor table can be unsightly and difficult to remove if not treated properly. Fortunately, with the right approach, you can restore your table’s appearance. Here’s a step-by-step guide to effectively eliminate mildew stains:

1. Prepare a Cleaning Solution: Mix equal parts water and white vinegar in a spray bottle. For tougher stains, add a small amount of mild dish soap or baking soda to create a paste.

2. Apply the Solution: Spray or spread the cleaning mixture onto the stained areas. Let it sit for 10–15 minutes to break down the mildew.

3. Scrub Gently: Use a soft-bristle brush or sponge to scrub the stains. Avoid abrasive tools that could damage the stone composite surface.

4. Rinse Thoroughly: Wash off the solution with clean water and a damp cloth. Ensure no residue remains, as this could attract more mildew.

5. Dry Completely: Wipe the table dry with a clean towel or let it air-dry in the sun to prevent moisture buildup.

To prevent future mildew growth, regularly clean your table and store it in a dry, shaded area when not in use. For persistent stains, consider using a commercial stone cleaner designed for composite materials.

By following these steps, your stone composite outdoor table will stay mildew-free and look like new for years to come.
