Granite countertops can look fantastic for years with just a little bit of daily care. Here are some tips for maintaining the appearance of your granite countertops and removing water stains as well as other types of stains:

  • Use water and mild soap or a natural stone cleaning product for daily cleaning. Acidic cleaning products or abrasives can damage the sealant on your countertop.
  • Wipe up spills as soon as possible. Acidic liquids like wine, orange or lemon juice, even soda and household soap, can break down the sealant and stain the surface.
  • To remove water spots, gently scrub the stain with a soft-bristled brush and a mild detergent and water. Rinse with clean water and dry.
  • To remove hard water rings around a faucet that have formed due to hard water sitting on the surface, try gently scrubbing with a Brillo pad or scraping softly with a razor blade. Wipe away any residue with a soft, damp cloth.
  • For stubborn stains, use a poultice or extractor. Poultice products made especially for granite can be purchased at a hardware or stone surface specialty store, or you can make your own paste using baking soda and water. Apply the thick, pasty mixture generously, then cover it with a plastic sheet and tape it around the edges with painter’s tape. Let it stand for 24 hours or more, then scrape up the paste and rinse the countertop with water.

If necessary, the cleaned surface can be resealed. Granite countertops may require occasional resealing. When water on the granite’s surface no longer beads up, contact a stone care professional to have your granite resealed.
