Hard water stains can dull the beauty of your marble outdoor table, but with the right techniques, you can restore its shine. Here’s how:

1. Use a Mild Soap Solution: Mix warm water with a few drops of mild dish soap. Gently scrub the stained area with a soft cloth or sponge. Rinse thoroughly and dry with a microfiber towel.

2. Baking Soda Paste: Create a paste with baking soda and water. Apply it to the stain, let it sit for 5-10 minutes, then gently scrub with a soft brush. Wipe clean with a damp cloth.

3. Vinegar and Water (Diluted): For stubborn stains, mix equal parts white vinegar and water. Dampen a cloth with the solution, place it on the stain for a few minutes, then wipe clean. Avoid prolonged exposure to vinegar, as it can etch marble.

4. Commercial Marble Cleaner: Opt for a pH-neutral cleaner designed for marble. Follow the product instructions to safely remove stains without damaging the surface.

5. Prevent Future Stains: Regularly seal your marble table with a marble-safe sealer to protect it from water marks and stains.

Always test any cleaning method on a small, inconspicuous area first. With these steps, your marble outdoor table will look pristine again!
