Granite Countertop Care: How to Remove Hard Water Stains

Granite kitchen countertops are great because they are tough and look great. However, everyday wear and tear can get to them if you’re not careful. Already have hard water stains? Don’t worry – we’ve got you covered. 

Remove Hard Water Stains

Follow these tips for removing hard water stains on granite countertops:

  • For water spots, you can use some gentle detergent mixed with water. Scrub lightly with a soft-bristled brush, rinse with water, and then dry.
  • For stains around faucets, use a scour pad or a razor blade, and scrape gently. Wipe away residue as you go with a soft, damp cloth.
  • For tougher stains, make a paste by mixing water and baking soda or talc with a diluted solution of hydrogen peroxide, bleach and ammonia. Scrub gently using a soft brush, and rinse with water. Depending on how stubborn the stain is, you may need to repeat cleaning several times.
  • For the toughest of stains, you may have to turn to an extractor or poultice. You can buy these products from stone surface or hardware stores, or you can make your own by mixing hydrogen peroxide and flour. Apply the thick, pasty mixture generously, and cover with a plastic sheet. You can secure the plastic sheet with some painter’s tape. Let stand for at least 24 hours, and then scrape the paste off and rinse with water. 


Granite countertops require occasional resealing. Once water stops beading on top of the granite, it’s time to have the countertop resealed.
