Hard water stains can mar the beauty of your slate outdoor table, leaving unsightly white or chalky deposits. Fortunately, there are several effective ways to restore its natural elegance. Here’s a step-by-step guide to removing hard water stains from slate:

1. Vinegar 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. Scrub gently with a soft-bristled brush, then rinse with clean water. Avoid using undiluted vinegar, as it can damage the slate over time.

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

3. Commercial Cleaners: Use a pH-neutral stone cleaner designed for slate. Follow the manufacturer’s instructions to avoid damaging the surface.

4. Prevention: To minimize future stains, wipe the table dry after rain or spills and apply a slate sealer annually.

Always test any cleaning method on a small, inconspicuous area first. With these tips, your slate table will stay stunning for years!
