How To: Clean Your Granite Countertops

I know at first this doesn’t really seem like necessary “how to.” I think most of us have learned how to wipe off countertops by now, right? Right. Except that granite countertops require a slightly different cleaning ideology. Don’t worry, it’s no 12 step process.

"Hooray! I've mastered the art of countertop cleaning!"


The key to keeping your countertops streak free, build-up free, and looking like new is simple. I think it can be broken down into three easy rules:

1. Less is More

The polish and shine of granite countertops comes from the polishing process.  Similar to wood, you start with a very coarse polishing pad and move onto progressively finer pads until the stone shines. This means that you don’t need a specific product to keep your granite looking like new. For everyday cleaning I like to use just plain water or a chemical-free all-purpose cleaner (the kind you would find at a health food store) for sanitizing. We also give our customers an unlimited supply of high end 3-in1 Cleaner, Sealer, Polisher that can be used as often as you need it.

Sealing & cleaning are so easy your puppy could do it!


2. No chemicals, abrasives, or wax based products

That means NO WINDEX! Homeowners ask me why their granite is dull looking. I ask “Are you using Windex?” and the answer is almost always “yes.” If your granite doesn’t look shiny or it looks greasy, then I’m guessing you’re use either a  chemical or something soapy like dish detergent. The chemicals dry out the your stone, and the soapy products leave a buildup on the granite that just gets thicker every time you use more of it to get that smear off.

3. Seal it once a year

While sealing is not always essential (it depends on the color of stone), we highly recommend it.  Granite is naturally porous. Sometimes, liquids can absorb into the stone. They will evaporate back out, but depending on which granite (they all have different compositions and therefore different rates of evaporation) it could leave a mark for a couple hours or even a day while it does so. Sealing is a simple process. We give our customers an unlimited supply of bottles of 100% silicone sealer. Once a year, you pour it onto the countertops, wipe it in, wait 15 minutes, and wipe off the excess. The sealer stops liquids from absorbing into the granite. This means your granite will be easier to clean, and retain its original luster. This is a great way to maintain your granite since silicone has a very low chemical reactivity.  It’s safe. It’s sanitary.

    planning to put leathered granite all over my kitchen counters
    i cook a lot and clean a lot!
    what are the cons of leathered granite? do you sell a lot of it?
    are your customers happy?
    any help would be appreciated

      Hi Donna,

      Thanks for messaging. We put leathered granite in kitchens all the time! You treat it exactly like polished granite. The only difference is how it looks (leathered doesn’t have the shine that polished does). Please let me know if you have any other questions!

    I had black leathered granite put in my kitchen. Three problems–1) the seams are surrounded by excess putty, 2) the backsplash and back of counter got silicone on them, & 3) the edges are not as polished/shiny as the counter finish. How do I correct these three problems? Thank you!

    • Katie says:


      Thanks for messaging us. These are primarily installation/fabrication issues. There is nothing you can do about the edges at this point. Unfortunately, these would have to be refabricated in a shop. The “putty on the seams” is hopefully not putty. If there seems to be a lot of Akimi/epoxy, they are really poor seams. A seam should be an 1/8th of an inch wide. Again, this is an installation issue. Silicone is the right product to use where the backsplash meets the countertop, but it should be clear and undetectable. This can be taken out and redone properly. I would contact the company that originally installed the kitchen and explain your disappointment. You are justified and you have a good eye for quality work which you did not get. Please let me know if you have any other questions. Good luck!

    Great tips, thanks! We have leathered granite in our kitchen and the crevices have collected a good deal of debris and paper towel lint that seems impossible to remove. No matter how much we clean them, they always look dirty. Any tips? Thank you!

    I can’t wait to see the answer as well. We just had black leathered granite installed. The tiny pits/crevices almost look like some of them are filled with the construction dust. And parts of the granite are hazy and other parts are blacker (streaky). The fabricator says the streakiness is a characteristic of the stone. She also said they sealed it before bringing it out. From everything I read i wonder if this streakiness is uneven sealant. And what to do about the crevices that appear dirty? Will acetone take care of both of these? I am reluctant to try hut hopeful for a solution. The fabricator is very difficult ao if there is something simple i can do myself, I’d rather at this point. Thoughts??

    • Katie says:


      Thanks for the message. First of all, the streakiness you are seeing could be a result of the stone. It also could be the way it was leathered. For example, if it was leathered by hand, in a fabricating shop opposed to at a manufacturer. Another reason could be the way the sealer was applied. Using Acetone is a good start. Use a rag and wipe the surface of the stone with Acetone. Then, reseal the stone with a 100% silicone sealer. Another idea is to apply ager to the stone to enhance its rich color. We get our ager from a company called GranQuartz. Please let me know if you have any other questions. Thank you!

    We just had honed black absolute installed in our kitchen. Now that it’s in, we’re hearing all sorts of stories about water stains, oil stains, fingerprints, etc. Did we make the wrong granite choice? How do we keep it clean and stain free? Should it be sealed? If so, with what? I’ve read that Method Granite Cleaner works very well. Is this a product that you recommend? Thanks!

    • Katie says:

      Hi Barry,

      Thanks for the message. We have installed dozens of honed Absolute Black and never get complaints about staining. As far as maintenance on the stone goes, make sure that you apply a 100% silicone sealer. We recommend doing it once or twice a year. Another idea is to apply ager to the stone to enhance its rich color. We get our ager from a company called GranQuartz. Please let me know if you have any other questions. Thank you!

    We also have black leathered granite that we love in our kitchen. However, any drop of water leaves a watermark on the surface. We use a water softener, but live in a hard water area. Any idea how to remove the water spots without removing the sealer?

    • Katie says:

      Hi Kathy,

      Thanks for the message. It sounds like the sealer that was used is the problem here. The first step I would take to remove the water stains is to get a product called TSP from a local hardware store. This will remove the mineral deposits that have “stained” your stone. Then, I would reseal. Make sure that you apply a 100% silicone sealer. We recommend doing it once or twice a year. Another idea is to apply ager to the stone to enhance its rich color. We get our ager from a company called GranQuartz. Please let me know if you have any other questions. Thank you!
