Hard water stains can be a stubborn nuisance on basalt outdoor tables, leaving unsightly white or chalky marks. Fortunately, removing them is easier than you might think. Here’s a step-by-step guide to restoring your table’s natural beauty.

1. Identify the Stain: Hard water stains are typically white or grayish deposits caused by mineral buildup. Ensure the stain isn’t mold or algae before proceeding.

2. Gentle Cleaning Solution: Mix equal parts white vinegar and water in a spray bottle. Vinegar’s acidity helps dissolve mineral deposits without damaging the basalt.

3. Apply and Scrub: Spray the solution onto the stained area and let it sit for 5–10 minutes. Use a soft-bristled brush or sponge to gently scrub the stain. Avoid harsh abrasives to prevent scratching the stone.

4. Rinse Thoroughly: Rinse the table with clean water to remove any vinegar residue. Repeat if necessary for stubborn stains.

5. Prevent Future Stains: Dry the table after rain or spills to minimize water spots. Applying a stone sealer can also protect against future mineral buildup.

For tougher stains, a paste of baking soda and water can be applied as a gentle abrasive. Always test any cleaner on a small, inconspicuous area first. With these tips, your basalt table will stay pristine for years to come!
