Your gorgeous granite countertop was once cooling lava, which makes for a porous stone that, unfortunately, tends to stain. Luckily, restoring your countertop’s shine is a cinch, and all you need is some household cleaning supplies. [1] We’ll show you how to clean and buff those granite surfaces to make them sparkle, and also show you how to keep them that way.

Things You Should Know

  • Use a soft sponge to scrub down the countertops with warm, soapy water, removing any easier stains.
  • Use a razor blade to carefully chip away any stuck-on substances, or cover stubborn stains with a 3:1 mixture of baking soda and water for 1-2 days.
  • Scrub the countertop with isopropyl alcohol to disinfect it, then use a cloth to buff a few drops of cooking oil into the surface to give it a shine.

Cleaning and Buffing Granite Countertops

  1. Granite countertops are sealed to protect the stone from being weakened and damaged from everyday use. To test the seal, pour a few drops of water or cooking oil onto the countertop and check that water beads form, as this indicates that the seal is working properly. If the water soaks into the countertop, apply a granite seal or contact a granite restoration professional to get it resealed. [2]
    • Make sure you do this sealant test before you do any buffing and cleaning of the granite. Otherwise, you may further damage the deteriorated sealant or the granite itself.
  2. First, unplug any appliances and set them somewhere safe, like the kitchen table. Also remove any cutting boards, spice racks, or anything else that’ll get in the way to create a clear, obstacle-free surface to work with. Then, use a spare rag or a dry sponge to wipe any crumbs or other large debris into the trash. [3]

  3. In a bucket or other large container, add 1 US tbsp (15 mL) of mild dish soap to 1 US gal (3.8 L) of warm water water. Then, soak a soft sponge in the soap solution and use it to scrub away at the countertops, removing any oil stains or other dirty spots. Move the sponge in an “S” pattern to attack stains from multiple angles.
    • Or, use a commercial granite cleaning solution . Spray the solution lightly over the surface, then wipe it down with your cloth.
    • Never use harsh chemicals on granite. Although granite is a hard-wearing material, it must be treated gently to keep it looking good. Avoid products that contain lemon, vinegar, lime, ammonia, bleach, or glass cleaners, as these chemicals can break down the sealant and damage the granite over time.
  4. Thoroughly dry the countertops with a spare rag. Then, for more set-in or stubborn stains, don some safety gloves and wield a razor blade, or a bladed scraping tool . Tilt the razor blade so that it’s almost flush with the surface of the countertop, and carefully chip away at any remaining stains. Afterward, scrub the countertop again with your cleaning solution. [4]
    • Or, cover stubborn stains with a 3:1 paste of baking soda and water, then cover the pasted spot with plastic wrap for 1-2 days to let the paste absorb the stain, then scrub it away with warm water. This is especially handy for cleaning oil stains .
  5. Now that the countertop is all clean, use a spray bottle to spritz it all over with isopropyl alcohol . Let the alcohol sit for 5 minutes to kill any germs, then wipe it away with a microfiber cloth soaked with warm water. [5]
    • Or, mix 1 part of isopropyl alcohol with 1 part of warm water and use this solution to wipe down the countertop for a more hands-on disinfection.
  6. Soak a rag with warm water and wipe down the counters one more time. Then, with a dry microfiber cloth, wipe the counters again to dry them off. Using a microfiber cloth rather than a rag or paper towel helps prevent streaking and gives your counters a uniform shine. [6]
  7. Now comes the finishing touch. Pour a few drops of cooking oil—like canola or olive oil—onto a microfiber cloth. Then, use the cloth to buff the entire countertop, working in small, circular motions. This gives your countertop added shine, and also grants it some stain resistance. [7] Work until the entire surface is coated in a thin, barely-there film of oil that’s a bit tacky to the touch. Be sure to buff the edges, too.
    • Or, use a commercial granite polish for a more professional shine. Spray the solution lightly over the countertop and let it rest for the indicated time, usually 2-3 minutes, before buffing it in with a microfiber cloth.
  8. In most cases, your granite countertop will polish up nicely using simple cleaning agents. However, sometimes the granite can be too deeply scratched or damaged for home remedies to work. Contact a granite restoration professional to get your granite countertop professionally polished, and looking as good as new! [8]
    • Professionals use specialty tools and either wet or dry polishing techniques on the granite. These techniques are only recommended for professionals to use, as they can cause irreversible damage if they are done incorrectly.
    • Remove smaller scratches at home by buffing a dab of granite polishing paste into the scratch.

Maintaining Granite Countertops

  1. Liquids that are left on granite for too long can cause dark, shadow-like marks to form, especially coffee, juices, wine, or sodas. Similarly, bright-colored beverages can stain light granite countertops. Get into the habit of wiping up spills with a soft cloth as soon as they occur to prevent stains from seeping into the granite. [9]
    • Also, keep bottles of oil or soaps on a dish to prevents passive leaks onto the granite.
  2. Apply cooking oil to a clean cloth, then make circular motions across the surface of the countertop. Use gentle pressure as you buff the surface. This will create a nice shine on your granite and temporarily reduce the risk of staining, as spills won't be able to soak into the granite as easily. [10]
    • Repeat this periodically, such as daily or once a week, depending on your preferences.
    • Use whatever oil you typically use for cooking. For example, you can use vegetable oil, olive oil, or avocado oil.
  3. Although granite is very hard-wearing, it can still be damaged if you regularly cut straight on the surface. Always use a cutting board when you’re preparing food and try not to leave any sharp objects directly on the countertop. [11]
    • This will also help to protect your knives and keep them sharp.
  4. Hot pots, pans, hair straighteners, and curling irons can all cause micro-scratches to form when the granite undergoes a sudden change in temperature. Keep a silicone, heat-resistant pad or an insulated mat within easy reach of the countertop. [12]
    • Hot objects can also cause the sealant to break down more quickly.
  5. Granite countertops are vulnerable to harsh chemicals like citric acid, ammonia, and other ingredients that may be found in beauty products. [13] Makeup and nail polish may tarnish the granite and break down the sealant with long-term exposure. Place these products on a tray or a mat, or leave them in a cabinet instead.
  6. The best defense against stains on your granite countertop is a good sealant. Sealants containing the ingredient fluorocarbon aliphatic resins are the most durable and water- and oil-repellent, and will last you up to 5-10 years. [14] Perform a sealant test every 6 months—place a few drops of water or oil onto the countertop and wait 15 minutes. If they’re absorbed into the counter, you granite needs a new coat of sealant.

    Although water can damage your granite, you can prevent water from sinking in by applying a sealant over the granite. After you apply the sealant, test it by putting a little water on the countertop. If it beads up, your seal is good. If it doesn't, you need to apply a better seal.

      • Avoid any sealant tests that involve lemon juice or other citric acids, as these can corrode both the sealant and the granite. [16]

You can also purchase a retail granite cleaner from the store and follow the instructions on the packaging to apply it. After you’ve finished polishing, wipe the countertop with a damp cloth to avoid a streaky finish. For tips from our Household co-author on how to preserve your granite over time, keep reading!
