Slate outdoor tables are durable and stylish, but they can develop unsightly base stains over time. These stains often result from moisture, dirt, or organic debris accumulating at the base. Here’s how to restore your slate table’s appearance:

1. Identify the Stain Type: Determine if the stain is organic (like algae or moss) or inorganic (like rust or mineral deposits). This will guide your cleaning approach.

2. Gentle Cleaning Solution: Mix warm water with a mild dish soap or a pH-neutral cleaner. Avoid harsh chemicals, as they can damage the slate’s natural finish.

3. Scrubbing Technique: Use a soft-bristle brush or sponge to gently scrub the stained area. For tougher stains, a mixture of baking soda and water can act as a mild abrasive.

4. Rinse Thoroughly: After scrubbing, rinse the area with clean water to remove any residue. Ensure no soap remains, as it can attract more dirt.

5. Prevent Future Stains: Apply a slate sealer to protect the surface and make future cleaning easier. Regularly wipe down the table to prevent buildup.

For persistent stains, consider a specialized stone cleaner or consult a professional. With proper care, your slate outdoor table will stay beautiful for years!
