How to Remove Stains from Granite Countertops

Question: “How do I remove water stains from my black honed absolute granite counter tops?”

Removing stains from granite countertops can be both a challenge and a puzzle at the same time. In order to remove a stain, you need to ensure that it is indeed a stain and not damage to the stone. Next, you need to determine what caused the stain so that you can apply the correct materials to remove it. Here are guidelines for determining the problem and the necessary steps to resolve it.

Stain or Damage?

Use these guidelines to determine whether the spots you are seeing are in fact stains or if they are areas of damaged stone. If you are unsure, consult a professional before proceeding.

Stains:

  • Discoloration from the stone absorbing a staining agent (coffee, tea, oil, etc.)
  • When the staining agent is removed, the stain is gone.

Damage: 

  • A change in the natural chemical makeup of the stone.
  • Not caused by the stone absorbing an agent, but rather caused by damage to the surface.
  • Corrosion, typically caused by acids, leaving “rings” or “water spots” that cannot be removed.
  • You cannot remove a “stain” that is actually damage as it requires repairing/removing the damaged area.
  • It needs to be determined if the damage is to the stone or to the protective coating/sealant. (Some types of granite do not require sealants and when they are applied, they become damaged and look as though the area is stained.)

Removing Stains from Granite

Removing stains requires the use of a poultice. A poultice consists of two materials: 1) an absorbent material, such as Bounty or Viva paper towels, talcum powder or diatomaceous earth and 2) a chemical to remove the stain. There are five different categories of stains and each has its own designated chemical for the poultice.

Categories of Stain:

  1. Stains: Organic (coffee, soda, mustard, gravy, tea, etc.)
    Chemical: Hydrogen Peroxide (30%-40% by volume)
  2. Stains: Inorganic (ink, dyes, dirt, etc.)
    Chemical: Rubbing Alcohol for ink; Hydrogen Peroxide (30%-40% by volume) for all others
  3. Stains: Oil (any type of cooking oil, some mineral oils, butter, margarine, etc.)
    Chemical: Pure Acetone (avoid using nail polish remover as different brands have different ingredients)
  4. Stains: Biological (mold, mildew, etc.)
    Chemical: Bleach or MB-9
  5. Stains: Metal (rust, copper, etc.)
    Chemical: Iron-out (a white powder available at hardware stores)

The Removal Process:

Due to the nature of this removal process, you may want to test a small, inconspicuous area of the stone to ensure there are no adverse effects.

  1. Begin by mixing the poultice (ex: talc powder and hydrogen peroxide). You will want to create a thick paste. It should have the consistency of putty.
  2. Apply the mix to the stained area, keeping it only on the stain. The layer of paste should be about one fourth of an inch thick and overlap the stain about a half an inch.
  3. Cover the area with plastic wrap and tape the edges down. Allow it to set for 24 hours.
  4. Remove the tape and plastic wrap only, leaving the poultice in place.
  5. Allow this to remain on the stain until it is completely dry. This can take anywhere from a couple of hours to a couple of days.
  6. When the paste is completely dry, use a plastic scraper to scrape away the paste.
  7. Wipe remaining paste away with a clean cloth.
  8. Clean the area as normal and dry with another clean cloth.
  9. If the stain remains, you may need to repeat steps 2-6 several times, especially for oily stains, each time removing more of the stain.

Water Stains

Most water stains are only a temporary problem. The granite may darken or lighten in color when the water is absorbed into the stone. However, once the water evaporates, the color of the stone should return to normal. To prevent this absorption from happening in the first place, it is necessary to seal the surface of the granite with a high quality sealer. This can be completed on your own or by a professional.

If hardwater stains occur, they can be removed by applying vinegar to the area using the same methods as above.

Repairing Damage to Granite

It will require professional assistance to repair damaged stone. You can also consult the location where you purchased your stone for advice and service options.

    Although staining a properly sealed granite countertop is unlikely, I found this article to be a good source of information about how to remove stains from granite countertops.

  2. Joe says:

    We put a bleach bottle down on the granite counter top – it left a ring. How can we remove this stain (ring)?

  3. Shelby says:

    We just got our granite countertops about two months ago and we were not told that we need to seal it. I got bacon grease on it and it left a stain. I am really upset. Has anyone tried to remove the stain with the combination they mention on this site? I am so afraid I will ruin it more.

    The granite around my kitchen sink has become darker. It looks like a water stain, but never drys, just seems to get darker. My housekeeper claims she did not use any cleaner on the granite. What could be causing the granite to be turning dark? Thanks in advance for any help you can give.

  5. Irma says:

    There was a glass left on my black granite coffee table for about two days while I was away for the weekend. There is a glass ring stain that will not come off. What can I use to clean the stain that will not damage granite? I’d very much appreciate any help. Thanks!!

    The granite around my kitchen sink has become darker after I used oven cleaner for the sink. How do I remove the stain?
    Thank you so much.

  11. Jim says:

    In Nov. 2009, I spilled bleach on my black honed granite. It left a stain that was lighter than the stone. Turns out that the stone itself will not stain, it being non-reactive to the high pH of bleach (alkali). What happens is that the sealer gets etched, so here’s what I did. I carefully applied a methylene-based paint remover according to instructions just to the spots. I then treated the spots with an enhancer according to instructions, which I repeated three times. Wax on/wax off. It wasn’t completely gone right away, but it’s almost a year now and the stain is gone. Saved $600 for grinding and resealing.

  12. Jim says:

    Hand soap is alkaline, but mildly so. Granite is non-reactive and the soap is too mild to etch the sealer. My guess is what you got is a water stain where water gets under the sealer and darkens the color. Give it time and it will dry out and the stain will disappear. Again, my guess.

  13. Josh says:

    Hello,

    I have a water stain around my faucet that won’t dry up. I had granite counter tops installed about a month ago and we have noticed a water stain building up around the ring where the faucet is installed. We removed the faucet and have left it to dry for 5 days now and the stain is no different in color than when we started the drying process. How can I get this water stain to dry up?

    I know once it is dry, I will seal it like crazy, but until that time, I need advise on how to get this water stain out.

  14. Sasha says:

    Thank you so much for posting this information to get stains out of granite! It worked GREAT!!! My five-year-old daughter had left one of her many art projects on our granite countertop. This particular masterpiece was done in permanent marker. Over the weekend, we had many people in and out of the house and at some point, someone placed an empty glass on the art work. The water coming from the outside of the glass caused the ink to bleed into the granite. Worst part is no one noticed it for a day or so…the ink was blue and the granite is almost white! It looked so bad; I just knew we were never going to get it out! I took the saran wrap off at 8:30 p.m. last night, allowed it to dry over night and this morning it came off beautifully! Thanks again for saving our counter!!!

  15. Julie says:

    Regarding water stains around the faucets (sink). My plumber just installed a sink over new granite counter. He began using “putty” to install fittings and remembered out loud, “I need to use only silicone to install these; putty will darken the area around the faucet and I had to buy someone a new countertop for this mistake.” Check and see what your plumber used. Hope this helps.

  16. Barbara says:

    I have what I think are water stains in two places around my sink. I want to reseal the counter, but not until the stains go away. Any advice on how I can help these stains dry quickly? With it being around the sink, I feel I will never get to reseal it. I tried using my hairdryer, but did not see a difference. I appreciate any advice. I thought a granite countertop was the toughest and easiest material to take care of. Doesn’t seem to be the case so far…

  20. Sue says:

    I put a few layers of newspaper on my dark grey granite bench top, then put oven shelving on the newspaper and sprayed it with oven cleaner, not realizing that the oven cleaner would soak through the newspaper and onto the granite bench top, which now has streaky, light marks on it.
    Could you suggest what I might do to try and get rid of these “streaky” marks? Many thanks.

  21. Deborah says:

    We put in a faucet that turns on when you touch it, and it left a stain on our granite countertop, which we believe is from its battery. The stain is greenish in color. What kind of poultice would be best to try to remove the stain?

  28. Cindy says:

    I have a granite bathroom countertop that is a year old. The installer told me to seal it and when dark spots appear that do not dry, it meant I needed to reseal those spots. I did, but now I have what appear to be two permanent dark spots. I’m wondering if resealing just those two spots trapped something even though they were completely dry when I resealed. Do I need to remove the sealer and then do something else?
    Thanks, Cindy

  29. Lynn says:

    I used a bathroom cleaner with bleach and it left stains on the granite surface. What is the best method to treat the surface? I am confused; is it hydrogen peroxide and talc, or is it methylene paint remover?
    Please help…I’m moving from my rental soon.

  30. Robin says:

    My granite floor darkened after rain water seeped into my floor skirting, and underneath my granite. It has been a month, and that portion of the stone still has not reverted to its original color. Any solution? Appreciate your kind help!

  31. Cynthia says:

    We just installed a new vanity with a granite black top finish, and by mistake I picked up Scrubbing Bubbles instead of the granite wipes. It stained my granite top and left it with white spots. Please help; I tried granite cleaner and it didn’t help at all.

    Hi, my new black granite kitchen counters have white spots and rings from the bottoms of glasses. I am unsure what is making these marks, however I believe it might be caused from citrus fruits, as one mark was confirmed to be caused by a pineapple. Does anyone know how to either remove the stain, or color the marks back to black? Thanks.

  44. Ann says:

    Hi, I have black granite worktops and spilled some bleach on them. It was only there a couple of minutes, but it left a mark. You can only see it in certain light, but how do I polish it back to how it was before? Grateful for any help. Thanks.

  45. Gaby says:

  47. Rajesh says:

    I did a home-fix on my new white granite and after the final touch of acid wash, the granite turned yellow! Can someone please tell me how to restore the white granite color?

  48. Kelly says:

    I have a stain around my faucet caused by the plumber’s sealant. The whitish granite now has a dark ring around the faucet. I’ve tried flour, water and dish detergent with no luck. Then, I tried flour and hydrogen peroxide; again, no luck. What should I use and will this come out? My plumber says he’s never seen this happen; I think he didn’t know what he was doing now that I’ve read more on this subject. I can’t seem to find any solution to this problem; I’vbe read about others who have had this happen to them, but no one is posting what they did to remedy it. Please; any suggestion will be appreciated!

  49. Armen says:

    For a mouthwash stain, similar to soap stains that are dry, use a wet sponge and leave it on the stain for as long as it takes to dry up the sponge (24-48 hours). Remove the sponge and voila; the stain is gone!

  50. Rhonda says:

    Hi, I need HELP! I rent my home and I was using Lysol Toilet bowl cleaner in the toilet and did not notice that some had gotten on the bottle and I set it on the counter… it left a blue spot in the shape of a C on the counter! Is there any way I can get it out?

  51. Melanie says:

    Rhonda,
    I broke a red ballpoint pen on a counter at a house where I was visiting and tried everything I could find to get it out – baking soda, vinegar, rubbing alcohol, dish soap – to no avail. Finally, I found some Oxi-Clean laundry detergent and it worked! The stain was completely gone within minutes. It was the concentrated powder version. Good luck!

  52. Melanie says:

    Kelly,
    Plumber’s putty (used as a sealant) is a common cause for dark stains on granite around the faucet because it contains oil. Silicone is typically used as a sealant in place of plumber’s putty for granite or other natural stone sinks because even the non-staining plumber’s putties can sometimes stain granite. If the putty is causing the stain, you need to have the putty replaced, otherwise the stain will return. Try the acetone poultice to remove the stain.
    You can also try covering the stain with baking soda, talcum powder, cornstarch, or even flour to draw the oil out of the counter, similarly as one would for oil stains on a couch or concrete. If the dry powder doesn’t work, turn the powder into a poultice by mixing with either acetone or water to make a paste, apply the paste to the stain and wrap the area with plastic wrap to draw out the oil.

    I had a soap dish that turned moldy and spread on the granite. I used some bleach to remove it . Now there is discoloring and a ring around the paper towel dispenser. How do I get rid of the ring and the discoloration?

  54. Melanie says:

    Linda,
    Try the pure acetone poultice to remove the stain.
    You can also mix an oil-absorbing powder, such as baking soda, talcum powder or cornstarch with hydrogen peroxide to make a paste, apply the paste to the stain and wrap the area with plastic wrap to draw out the oil.

  55. Trina says:

    I just want to clarify something. Does the paste really require 30-40% Hydrogen Peroxide? I ask because I have been unable to find it anywhere except online. It is very expensive (at around $50 or more for a little bottle) and says it is highly corrosive.

  56. Zsofia says:

    I have a dark ring from cooking oil on my countertop. What type of paste should I use (what would I make it out of) and what other processes should I do?

  65. Sans Rival says:

    The stain I have been trying to remove came from the paper towel holder with an oil base rubber material bottom that inadvertently left a stain from where I had it near the sink. Would appreciate getting confirmation to use a cream of tartar and hydrogen peroxide poultice. Many thanks.

  66. Matt says:

    A plastic soap dispenser was left on the corner of a bathroom sink granite top. Over the winter, when the house was unattended, a dark corner resulted. I believe the plastic container split and soap was leaking on the granite. The granite co. placed a putty-type material on the stain and sealed it with a plastic cover. After 24 hours and two tries, the stain is still there…Any suggestions?

  67. Harry says:

    Read all comments regarding stains above, but not much help for I need specific input on how to remove bleach stains. Vague references to hydrogen peroxide and talk about methylene paint thinner isn’t much to go on. If u could dilate/clarify what, exactly, I need to do to, hopefully, restore the countertop or point me in right direction I would greatly appreciate it and I thank you in advance for your anticipated courtesy/assistance in this regard.

    Please advise how I can remove stains from a new gravestone made from viscount white granite. The stains were caused by a dissolved by rain red dye from an artificial flower left on the grave. It looks like the dye penetrated inside the granite stone. I would appreciate your help. Regards from Poland, Andrzej

    I have recently installed a granite countertop and in the process of installing the new backsplash, the installer mentioned he plans to do an acid wash (or spray) on the backsplash. I am concerned what might happen to the granite countertop if the acid wash is not confined to the backsplash. Please advise immediately, as he plans to do that today.

  75. Kathy says:

    THANK YOU so much for your insight and help! We left a container of strawberries on our sealed granite countertop for several days and it leaked a 12″ diameter stain. We made the hydrogen peroxide/talc combination and followed your directions to the letter. After it dried, I wiped it away and the stain was gone!!! I was so relieved!

  76. True story says:

    I have to agree with Idiot’s earlier post. I find it hard to believe that everyone is able to afford granite countertops, yet do not have the capacity/willingness to read the article above. If you are that stupid/lazy, how did you afford the granite in the first place? Take a minute and read the article before you post your moronic questions; you might realize your question has already been answered. Mold on your counter? Really?? How long do you have to let something sit and fester for that to happen? Advise immediately? Faith in humanity…long gone.

  77. Cathy says:

    New granite in bathrooms have ring where the antibacterial soap dispensers are. How do I get rid of it? Is it the water or soap that is staining it?

  78. Melanie says:

    Cathy,
    Since it’s in a ring shape, I would bet that it’s a water stain; like if there was still water on the counter when you set the dispenser down while cleaning, or if it dripped down the dispenser from your hand. If it were a soap stain, it would be more of a puddle shape from a leak in the dispenser. Since you are unsure, you may have hard water and the stain is actually a mineral deposit. In that case, use the article How to Remove Mineral Deposits from Granite Countertops. If you think it could be a soap stain after all, use the article How to Remove Soap Stains from Granite.

  81. Angela says:

    When renewing our kitchen last year, we decided to have granite worktops. After listening to peoples comments on which color is most recommended, we went to our local supplier. We asked him to recommend us a top most suitable for our needs. I have cooked for masses, for charities and love entertaining. The supplier showed me where the samples were, in open yard outside. We were left to choose without any help. We chose `Sahara Gold’. After 2 weeks of being installed, I accidentally dropped a cooked sausage. I immediately wiped the surface. Overnight, a greasy stain appeared. Also, near the sink water marks appeared. The supplier came and resealed all the worktops. Everything was fine for 2 weeks. Then, a dark mark appeared all around the cooking area and the sink. If you look at the thickness of the worktop, you can see a 1 cm deep darkness. Where we had a piece of heavy marble near the oven for hot items, when I lifted it, it had the original color on it. The rest of the worktops, which are separate areas, are not effected. When we asked the supplier to help us with this, he said it was our cleaning products. One particular one which we have only used for 1 month, since this January, got the blame. But the darkness was already there beforehand. Also, we used this product all around, and it hasn’t effected other parts. I contacted the consumer advice, they said the worktop is not fit for the purpose it is meant for, so I should ask the supplier to remedy it. And if not, then go to small claims court.
    Since then, we have seen many comments about problems with granite. If I had known this earlier, I would have had Formica or even the cheap MDF type. We had MDF for 11 years with 100% satisfaction. What a mistake it is to think that granite is best. As we have spent thousands on this awful granite; we are lumbered with it until we can afford to replace it. Any help will be appreciated.

  82. Laura says:

    We just got our granite countertops. There is this haze over the top of it. I was told that this is in the stone. Can it be damaged when they put sealer over it? Can this be fixed?

  83. Melanie says:

    Laura,
    The sealant could be the cause of the haze. Stone Care International says, “The haze that you see is from excess sealer that dried on the surface. This is normal for less-porous stones. The haze can easily be removed by reapplying the sealer to the surface, let it stay wet for one minute, and then buff off the excess with a clean and dry towel.”
    CountertopSpecialty.com agrees that the haze could be from sealant that dried on the surface, either from an improper application or because the stone is non-porous and may not need sealant. They recommend that you test the stone to determine if it needs sealant.

  84. Vera says:

    Hi,

    The granite around my sink has darkened and around my cooktop. Do you have any advise on how to treat it so it lightens up again? I’ve had the granite for three years. It was sealed when we had it installed. The name of the granite is Caledonia. I have tried a poultice with baking soda and mineral spirits a few times. It helped, but not enough. Do you have any other suggestions?

    Thank you.

    Hi, we got a small bit of over pride cleaner on our granite worktop and it has gone much lighter than the rest. Is this a stain or damage? What can we do to repair?

  86. Mattie says:

    My daughter left a glass with cooking oil in it on my new granite counter top, which supposedly had been sealed. Thinking that it could do no harm, I left it there. To my surprise, I found a deep stain (grease) on removal. I’ve tried acetone, vinegar and soda liquid detergent. What will get this out!

  87. Teri says:

    I have what appears to be a water stain around our sink by the faucet. We took the sink apart and it is not the faucet leaking. What can we do to remove the dark areas that appear to be water? We have not used anything that would have caused this problem.

  88. Melanie says:

    Teri,
    Dark stains around the faucet could be, as you said, water stains. Try not to use the sink for several hours or even a whole day to see if the stains evaporate, which would prove they are actually water stains. If the stains don’t evaporate, they probably aren’t water stains. Stains around the faucet are often caused by the plumber’s putty that is used to seal the faucet. Even the non-staining kinds of plumber’s putty often stain granite, which is why silicon is often used instead. A plumber’s putty stain is an oil stain, so try the acetone poultice. Even if you remove the stain though, you would need to have the putty removed and replaced so that it doesn’t stain the counter again.

    I have dark grey, very porous counters in my bathroom. It appears shaving cream drips were left unattended for more than we week and now left dark spots. There are other spotty areas which are mystery marks, but my guesses would be toothpaste, eye drops, as well as the identified shaving cream. In the event I can not remove these stains, is there a countertop stain that I could use to even out the color? Then, what is best sealer to use in a bathroom situation?

    Colleen,
    According to CountertopSpecialty.com, toothpaste and shaving cream stains are often not really stains as much as they are damage (etching). However, try removing the mark with a poultice first; either the peroxide or acetone poultice might work.
    Dying granite is very tricky because the stone is made up of a variety of minerals, each of which would absorb the dye differently. Also, there is no guarantee that the dye would cover up the marks/stains. As far as I know, there isn’t a dye sold commercially that is specifically used for granite, although if you want to paint over the stone, there are paints made for use on granite or stone.
    The sealer that you need depends on the particular piece of granite; some stones shouldn’t be sealed at all. Test your granite to determine if it needs to be sealed. If you do decide to seal the stone, Ethos Marble Care recommends the use of an oliophobic penetrating sealer for bathroom and kitchen countertops because it will seal the stone against not only water, but also oils. However, a sealant will not prevent future damage, such as etching.

    We have a bacon grease stain on our new granite countertop. What would you do??

  92. Melanie says:

    Bill,
    Since grease is so similar to oil, I would try the poultice for oil stains first. Butter is listed in the oil poultice section, but it is actually a grease because it is animal-based (dairy). If that doesn’t work, you can try the poultice for organic stains.

    My fabricator says he only used acetone on my white and grey granite. It turned the granite yellow. He says there may have been some ager on the cloth he used. Is there any way to reverse this?? The granite has not been sealed.

    I have a white cookie jar on my dark granite counter top that left a white ring. What can I use to get this mark out?

  95. Melanie says:

    Joanne,
    The white ring could be a water stain (if the cookie jar was still wet when you replaced it after washing). If that is the case, use the information in the Water Stains section at the bottom of the article.
    If the ring is solid, then it’s possible that the stain could be from sunlight exposure to all areas surrounding the cookie jar. If that is the case, your best option is to darken the spot, rather than try to turn the entire counter back to the lighter shade. To darken the spot, this is the article that you need: How to Restore Granite Countertop Color.

    Left a wrapped cube of butter on the counter top to soften. When I picked it up the next day, there was a dark stain. Can this be removed?

  97. Melanie says:

    Mary,
    That stain can be removed! Use the method for oil stains.
