Slate outdoor tables are durable and stylish, but they can develop stubborn clip stains over time. These marks, often caused by metal clips or other accessories, can be unsightly. Fortunately, removing them is easier than you might think.

First, start by wiping the stained area with a damp cloth to remove loose dirt. For tougher stains, mix a solution of warm water and mild dish soap. Gently scrub the stain using a soft-bristle brush or sponge. Avoid harsh chemicals or abrasive tools, as they can damage the slate’s surface.

If the stain persists, try a paste made from baking soda and water. Apply it to the stain, let it sit for 10-15 minutes, then scrub lightly and rinse. For deep-set stains, a specialized stone cleaner may be necessary—always test it on a small, inconspicuous area first.

To prevent future stains, consider using protective coasters or mats under metal objects. Regular maintenance, like wiping the table down after use, will also help keep your slate table looking its best. With these simple steps, your outdoor slate table will stay clean and beautiful for years to come.
