A slate tile surround adds an elegant and natural appearance to a fireplace. The slate, a stone product, requires certain cleaning tools and procedures. Stone has a porous surface, and acidic agents can erode the slate, leaving the tile discoloured and etched. A mild soap, and products made especially for stone surfaces, clean the slate tile and grout without sacrificing the beauty of the stone.

  1. 1

    Spray a dust rag with a stone-cleaning product. Wipe dust and dirt from the slate tile surround with the dust rag. Fold the dust rag to expose a clean area as you wipe.

  2. 2

    Fill a small bucket with warm water and 1 tsp mild dish soap. Wet a sponge with the mixture and wipe it over the slate tile. Start at the top of the tile on the fireplace and work your way down.

  3. 3

    Discard the soapy water and fill the bucket with clean, warm water. Rinse the slate tile with the sponge and water. Dry the slate with a clean microfiber cloth.

  4. 4

    Pour 1 to 2 tbsp of tile sealant onto a soft cloth. Wipe the cloth over the slate tile. Wait 30 minutes and apply a second coat. The sealant adds a protective barrier for the stone.

  5. 5

    Apply 2 tbsp of mineral oil onto a clean cloth. Wipe the mineral oil over the tile after the second coat of sealant has dried. Mineral oil adds shine to the slate tile.
