Caring for Your Bluestone Countertops

July 2, 2020 Published by Leave your thoughts

Bluestone has long been a favorite material for landscapes and gardens. It has since moved indoors, especially to kitchen countertops, laundry rooms and even mudroom floors. While it is impervious to sudden temperature changes—making it an ideal material for Brooklyn, NY—it will get dirty, and if you invest in it, it’s important to know how to clean bluestone. Here are four tips for taking care of your bluestone countertops:

  • Do not underestimate water: Bluestone is popular for pavers because it’s water resistant, and when wet, it is not slippery. This can also be an advantage for kitchens, since spills can make for a messy and sometimes dangerous area. When installed outdoors, hosing off and sweeping is often all bluestone patios need to stay clean. The same approach works for your kitchen—most stains and messes can be cleaned up with a quick stroke of a wet rag.
  • Look out for oils: While water is not an enemy of bluestone, cooking oil can leave stains. Wipe up any cooking spills as they arise. Do not let olive or vegetable oil linger on your countertops. If you overlook a drop or two and a stain develops, ammonia can help you remove it. Add two teaspoons of ammonia to a liter of warm water. Dip a small scrubbing brush in the solution and scrub until you pull most of the oil out of the stone. Rinse and let it dry overnight. Ammonia is tough on your respiratory system, so be sure to use gloves and a mask to avoid contact with it.
  • Keep mineral spirits handy: If a stain remains even after you scrub and dry the spot overnight, do not use stronger cleaners. Bluestone is also resistant to chemical cleaners, so the typical Lysol products will likely not make a dent in the stain. Mineral spirits and other household acetones can address the tougher stains. Rub the stain with mineral spirits, including the surrounding area. This will remove it completely, or at the very least blend the stain into the stone so it’s less noticeable.
  • Control mineral deposits: Mineral deposits are a larger problem for bluestone installed outdoors, but as kitchens are constantly exposed to water, chemical cleaners and soap residue, you may notice them on your countertops as well. They present as white spots or scaled layers and will detract from the beauty of the stone. The safest and most effective way to remove mineral deposits is with a vinegar and baking soda paste. Just as with mineral spirits, rub the mixture into the deposits, and when you start to remove them, rinse thoroughly.
