Hard water stains can be a frustrating sight on your beautiful obsidian outdoor table, but don’t worry—there are effective ways to restore its natural shine. Obsidian, a volcanic glass, is durable but requires gentle care to avoid scratches or damage. Here’s how to tackle those stubborn stains:

1. Vinegar and Water Solution: Mix equal parts white vinegar and water in a spray bottle. Lightly spray the stained area and let it sit for 5-10 minutes. Gently scrub with a soft microfiber cloth or sponge, then rinse with clean water.

2. Baking Soda Paste: For tougher stains, create a paste using baking soda and water. Apply it to the stains, let it sit for 15 minutes, then scrub gently with a soft brush. Rinse thoroughly to avoid residue.

3. Commercial Stone Cleaner: Use a pH-neutral stone cleaner designed for obsidian or similar surfaces. Follow the product instructions to avoid damaging the table’s finish.

4. Preventive Measures: To minimize future stains, wipe the table dry after rain or spills and consider using a sealant for added protection.

Avoid harsh chemicals or abrasive tools, as they can scratch the obsidian. Regular maintenance will keep your outdoor table looking sleek and stain-free for years to come.
