How to Remove Hearth Concrete Stains

Concrete is a highly porous material, which means it can easily suck up materials that are spilled on it. If your hearth is made of concrete, it probably has been finished to prevent spills from staining. But if your hearth is old or if you spill wine or lemon juice or other hard-to-remove liquids, practice some quick stain removal to clean it.

Things You'll Need

  • Water
  • Liquid dishwashing detergent
  • Paper towel
  • Fine-grit sandpaper
  • Concrete sealer
  • Paste wax
  • Clean cloth

Wipe the concrete hearth so that it is free from dirt, grease and oils. If needed, clean the stained area with a solution of mild liquid dishwashing detergent and water. Dry the area completely with a paper towel.

Sand the stained area gently with the fine-grit sandpaper until the stain has been removed.

Wipe away the concrete residue with a paper towel.

Apply the concrete sealer to the stained area and follow the manufacturer’s instructions. Rub the sealant into the concrete and allow it to dry for the recommended time.

Apply paste wax to the corner of a clean cloth and work it into the formerly stained area. This will help restore the patina of the concrete hearth and protect it from scratching and staining.

Tips & Warnings

  • Contact a professional if the stain has penetrated beyond the top layer of the concrete.
