How to Remove Stains from Marble 

Awesome glad to hear that!

Awesome! So great to hear that! 👏👏

Wonderful!

Oh dang! Yah grease stains will need some kind of surfactant (clear with no dyes!) to remove. I would try rubbing alcohol or ethanol (something clear like Vodka or gin) first and then if that doesn't help with the grease, I would add a few drops of clear dish soap and try again. The baking soda doesn't actually "do" anything except act as a kind of magnet to pull the stain out of the marble and the water or other liquid allows the stain to flow up to the baking soda. Keep in mind that after putting the poultice on the stone it can cause a darkened spot from water entering and hydrating the stone. This should fade away over a day or two as the water evaporates.

Hi, my oil stain got bigger too, did you remove it eventually?

Thats so sweet

Thank you

I think I lost track of reality. I might need some Barbs ( PO Box 193 Clifton Hill 3068 Victoria Australian ) thankingu

To see what it was like watch Bill and Ben the flower pot men and listen to Puff the Magic Dragon. It was weird living back then and we knew it then as we know it's now.

Whoa whoa whoa! There's certainly tougher, more stain resistant options out there (quartz, granite) but none have the timeless elegance of marble! We embrace the "patina" that comes with use on our counters. They are also honed so don't show etching/scratches like a polished marble surface does. But yea if you want flawless whiteish counters don't go with marble.

Now you tell me!

It's just a friggen countertop. Why use an expensive, high maintenance material for a kitchen application that will involve assorted foods, colored beverages, hot & cold kitchenware, strong cleaners, and dozens of other staining situations & possible chemical reactions? It's as absurd as those neurotic people who have white carpets & white furniture in their living rooms. How can adults, children, food, drinks and pets actually live in peace in a white room? Some go so far as covering their white furniture with clear plastic, like some sort of furniture condom. One can, however, find all white rooms in psychiatric wards, so yeah - nutcases use the same decorative styling. Instead of getting bent out of shape every time a child or guest does a no-no on your marble countertop, just get an inexpensive, easy to clean basic countertop and go enjoy your life. Or, you can become an expert in applying poultices to marble and research the chemistry of cleaning stained marble. And maybe, after fussing with that, find some other cool trendy things to get all neurotic about while waiting for global warming to fully take hold...

I think you might be right, we have fireplaces 600 year old fireplaces my aging mother thinks need ripping out over stains, I've suspected Alzimers for a bit now..this probably proves it..

@@TheGRITandPolish you mentioned something about a protective coat of something but didn't illiterate, ikr I probably need a building counter tops video for that information, I'm trying to save our beautiful marble fireplace from my mother ,there very very old n it would be a crime to pull them out because of normal fireplace stains..OK looks like they have never had stains removed in probably 600 or so years..If I can get them clean I'll save a fight because I can't let her do that, she's getting on n I think is losing it a bit..I'd also say they're worth a fortune.. it was My dad's family estate she's supposed to be protecting it not destroying it, but I know she knows this so stains removal is exactly what I need..

You know John we didn't do that. But it would certainly help the liquid in the poultice to penetrate the marble more fully since it wouldn't be evaporating. When we checked on ours the following morning it was dried out and if it was covered in plastic wrap it would have stayed wet for much longer. I think this could be helpful for deeper/more stubborn stains.

Great suggestion.

Yes this method does make a water mark in the marble but it is temporary! It evaporates after a day or two. The hydrogen peroxide won't harm the marble and is a good option if just water-based paste is not enough lift. Leaving the paste on for an extended time allows the stain to travel into the paste and some stains won't lift if there's only a short time. You can also repeat the process a few times if the stain doesn't come all the way out on the first try. It's basically harmless to the marble : )

@@TheGRITandPolish Thanks so much for this! Okey dokes, I'm going to give it a go! 😃 I'll let you know the result. 😁 Much appreciated!! 🙏🏻🙏🏻

@@TheGRITandPolish Ok, so I've done it and the stain from the decanter is completely gone!!! 😃🙏🏻✨ So happy, thank you!! The only thing is, the other mark from the piece of cheese that fell onto the table is still there. Not toooo noticeable, but if you've got a hack for getting rid of stains that might be more oil based, I'm all ears. Thanks again!!! 😃

Is this safe for pink marvel, with an orange stain that about 10 years old ?

I tried a similar method which said add lemon, it was to remove rust marks. It works but slightly etched the marble which I'm going to keep re polishing.

Hi Jane yes I would start with 3%-6% on the hydrogen peroxide and then regarding the soap ring, it sounds like the marble top was etched and this is actually a physical process that breaks down the surface of the marble so it requires a physical process of sanding/buffing to restore it. You might try a super fine grit wet/dry sand paper (3000-5000 grit) and give it a light go with a little water. If it looks promising keep sanding/buffing till the surface has regained its polish.

​@@TheGRITandPolishif we use the hydrogen peroxyde on polished marble surface, will it destroy the surface?

Use12%

Oh no! Yes I would use mineral spirits

The GRIT and Polish awesome!! Thank you for replying!!

@@TheGRITandPolish hello, what is mineral spirits? I am from Aus and am not sure what you mean by this. Thanks!

@@anam3763 White spirit (UK & Ireland) or mineral spirits (US, Canada), also known as mineral turpentine (AU/NZ), turpentine substitute, and petroleum spirits, is a petroleum-derived clear liquid used as a common organic solvent in painting.

Start with this simple recipe and try a couple applications. If you don't notice any difference, try with mineral spirits instead of water.

Awesome good luck!

HI Daniel. The paste will indeed leave a darkened hydration mark. This shows that water has penetrated the marble and will provide a path for the stain to travel into in the baking soda paste matrix. The water mark should evaporate out with in a day or two. You can speed the process with a fan or mild heat (blow dryer). If water doesn't work try mixing the baking soda with hydrogen peroxide. You can also cover the paste with plastic wrap to increase the time that the stain remains hydrated. Keep in mind that this method works best for colored organic stains (like wine, yellow from tumeric, or tea).

Dang so sorry to hear that! Yes if the surface is rough it typically means it's been etched. But you may still have some luck removing the pink color. First try the poultice with hydrogen peroxide and baking soda. It may take a few applications to remove it completely. But if the hydrogen peroxide haas no affect, try making the poultice with mineral spirits and baking soda. This will remove stains that are hydrophobic and prefer a non-poplar environment.

This may help but if not sub mineral spirits for the water. That should be more effective at removing fat/grease based stains.

@@TheGRITandPolish appreciate that.

Water marks should evaporate on their own within a day or so depending on the environment. You can speed the process using a hair dryer or fan if needed. If they don't go away then there's likely something else besides water, such as an oil, in the marble.

Surface spots from lemon are usually from the acids in the juice dissolving a thin layer of marble leading to a rough area that can be noticeably different than the smooth polished finish. There's no good way to restore the finish without re-polishing the surface. : (

So this is due to an actual chemical reaction between the caustic soda and the kitchen top that results in the marble surface being dissolved so it's no longer glossy and polished like the rest of the counter. The best way to remove the hazy whitish blemish is to polish it with a diamond wet polisher or a high grit sand paper (like 3000 grit).

The age of the marble shouldn't really matter. New polished marble will have a uniform glossy finish and may be sealed. In this case the poultice may take longer to penetrate into the marble to remove the stain.

The best way to restore the polished marble surface is to use a wet polisher with a diamond pad. You can also try sanding with a very fine sandpaper such as these 3000 grit papers. amzn.to/3HltN16 I would try them this in an inconspicuous spot first to make sure it gives a similar polish as the rest of the surface.

The lysol has a pretty basic pH so will dissolve the marble surface leading to an etch mark and etching can only be removed by re-polishing with a diamond pad. If water marks are a nuisance you can seal the marble with a high quality stone sealer like this: amzn.to/3AITzsL

Water spots will typically just evaporate on their own after a day or two. This method is most helpful when there is some undying colorant to the spot that you would like to lift and actually will hydrate the marble where the poultice is applied creating a temporary dark spot. You could speed the drying by placing dry baking soda on it or use a space heater or fan. If water spots are a frequent issue, once dry apply a high quality natural stone sealer such as amzn.to/3xbw21t

Yes I would use this method first. One thing to note though is that juices are often acidic (orange juice has lots of citric acid) and can etch the marble surface leaving a dull spot. This can only be removed by repolishing the surface with a diamond pad. The baking soda + water or hydrogen peroxide is good a removing organic colorants so if your spot is purple from grape juice then this should be successful.

Well dang! Hair bleach is an alkaline solution (higher pH) that can actually dissolve the surface of marble. This would look like a sightly rough patch on the polished surface. The only way to restore this type of etching is by polishing with diamond pad : (

Well since no one has responded I'll chime in with our own experience. I have to note that our marble is honed so it doesn't have that glossy shine for a finish. So I can't say whether this method affects the polish. If you have this type of finish it might be a good idea to try it in an inconspicuous spot first. That said, this poultice has worked well for us on organic stains such as colored spots from spices, (turmeric!) flowers, and fruits--things that were once living. We also found that using hydrogen peroxide instead of water was a more powerful stain remover. We did notice a darkened spot under the poultice after we scraped it off but I think this was just moisture that was absorbed into the marble and it was gone after a day or two. It's not likely that this poultice would work on a stain oil-based stain like a dark spot from olive oil left on the counter. For this you would need to use mineral spirits in place of water. Also keep in mind that repeated applications may be necessary depending on the depth and intensity of the stain.

👏 🙌 😄

Yes a dark spot that can appear brownish is due to hydration of the marble by the water in poultice. This is an indication that the poultice did its job in penetrating the marble to allow the stain to flow into the baking soda. It will evaporate away within a day or two but you can speed the evaporation by applying dry baking soda or a fan/hair dryer.

It's always a good idea to test in an inconspicuous spot first! But the physicochemical properties of baking soda in water (or hydrogen peroxide) are not compatible with etching marble. However it will likely leave a water mark where the poultice was applied which looks like a darkened spot. This will fade over a day or two as the water evaporates out of the marble.

@@TheGRITandPolish thanks. Hopefully, that will be true.

Dang that sounds like a bummer! The great thing about this poultice is that it's not likely to harm any existing marble nor make stains worse. Hydrogen peroxide can kill mold as well so this would be a good one to try if mold is suspected and you don't want to use something stronger like bleach which could etch and damage the finish on the marble. The trick is to allow the hydrogen peroxide to soak into the marble and this is what the baking soda does. You can also do this by soaking a washcloth in hydrogen peroxide and placing it over the affected areas.

Our pleasure!

So sorry to hear that! But here's what I would try. Make the poultice with clear acetone (which is the main solvent in nail polish remover) in place of water. Cover it with plastic wrap for a few hours to prevent the acetone evaporating too quickly. After 3 hours or (whenever the acetone has evaporated) remove the plastic and let the acetone evaporate until you're left with dry baking soda. Scrap it off and check to see if the stain is gone or has lightened. You can repeat that process until it's gone. If the acetone doesn't have an effect, use hydrogen peroxide to make the poultice and let it set on there for at least 3-4 hours. I think between those two methods you'll be able to get the purple out! Good luck.

I would try isopropyl alcohol or acetone first and then if needed go to something stronger like Goof off.

For oil stains sub mineral spirits for the water/hydrogen peroxide

You can also try subbing in mineral spirits for the liquid. This will preferentially lift oil-based stains.

Oh dang! We just put in a marble hex shower floor... so we'll see how that goes. Yellow marble stains are often due to rusting of iron present in marble tiles. There are a few different chemical solutions that can be used to remove the iron but the process isn't straight forward and unless the underlying cause is addressed (water penetrating into the tile) the stain will come back. It's also possible that the yellow is from the iron in the water. You can test for iron especially if your water is from a well and if this is the case then treating your water to remove the iron should do the trick in the long run.

Alwin I'm wondering if you're seeing the steel plate itself through the marble. The opacity of marble varies and since light can travel through it, the dark steel plate may actually be visible?

For a grease stain, I would sub mineral spirits or clear acetone for the water and make a "spirits" poultice. Same process overall though.

Cement on marble would usually need mechanical removal. Scrape, sand or polish

Definitely try with hydrogen peroxide. It might take a few rounds.

If it's marble, vinegar isn't advisable. Due to it's acidity, the vinegar can actually dissolve the marble. The baking soda will have neutralized the vinegar if enough was added. I would try this poultice with backing soda and hydrogen peroxide. Leave it overnight and repeat the application if needed. Keep in mind that the liquid may create a darkened spot under the poultice. This is good because it means the hydrogen peroxide penetrated into the marble to remove the stain. This watermark should evaporate away within a day or two.

Acids like lemonade can actually dissolve the surface of the marble in a chemical process called etching, resulting in a dull spot that may be rough compared to the rest of the smooth polished marble surface. The only way to restore the glossy finish is through polishing with a diamond pad. However if there is a colored mark like a yellow from a dye in the lemonade this would work.

Thanks!

The great thing about this poultice is that it is a very gentle way to get rid of stains so I would start with this method and then escalate if needed. Unpigmented darkened spots are typically from water or from oils seeing into the marble. If you do this poultice you will likely notice a darkened area of hydrated marble after you remove the baking soda and this will evaporate out after a day or so. If the spot is from oil, clean it well with clear dishsoap and the use mineral spirits in place of water to make the baking soda poultice to draw out the lipids.

This mix only works for water-based stains. You can try the same process but substitute mineral oil for water in the poultice and then this can work on oil-based stains. Keep in mind after removing the poultice, a water mark will likely be present but this evaporates off after a day or two.

@@TheGRITandPolish thanks!

Ours too...!!

Oh dang! Since vinegar is an acid it's likely that it dissolved a thin layer of the marble surface. This process is called etching and is especially apparent on polished/glossy marble. If this is the case then the only way to restore the gloss is by re-polishing the surface. However if the stain is from the color of the vinegar, like a dark spot from basalmic vinegar, then this would be a great thing to try and would likely help to lighten or remove the discoloration.

Shanti sorry to hear about this stain! It depends if the yellow is a dye from the hand soap? In this case the hydrogen peroxide/baking soda could help. But sometimes yellowing is due to the oxidation of iron that is naturally present in the marble. Essentially, iron in the marble can rust if exposed to water or acids or bleach. If your yellow coloration is due to this iron reaction then this poultice won't help.

Hi Jordan! I did this with a lemon squeezer the other day. Some juice dripped onto the counter and I quickly wiped it up but I forgot to clean up the squeezer and left sit on the counter for ~an hour and sure enough it etched the top. But our counters are a little "rustic" so we just say they're getting a nice patina ; ). If it's a classic champagne, I don't think the mark you're seeing is a stain in the sense that it's a color pigment from an organic source seeping into the marble and these are the types of stains that this poultice will have the most luck removing. I have two guesses as to what's going on in your case. One is that it's actually just a water mark that will go away as the water evaporates over a day or two. Another possibility is that the finish/counter top has been etched by the acids in the champagne. This is a physiochemical process whereby the marble is actually dissolved. There's no way to restore etched marble without refinishing or re sealing the countertop. You can tell if the marble has been etched by feeling the spot to see if it's different than the unmarked countertop. Hope that helps!

Try baking SODA not baking POWDER. Makes a big difference.

Agree that there's still yellow. But it was lighter after the poultice and it can take multiple applications to completely remove a stain. Also the poultice in the video is made with water. If you use hydrogen peroxide instead it is a more powerful stain remover.

The acid will permanently "etch" the cement floor so I think the surest way to remove it would be a concrete polish/sand. Alternatively you could try to paint over the spot with a concrete paint to conceal it.

Keep in mind that Vimto is carbonated so pH will likely be acidic. Acids (and also strong bases) can dissolve some of the marble leaving a permanent mark called an etch. These are especially noticeable on glossy polished marble surfaces since they create a dull-looking spot. The baking soda poultice will only remove colored stains and won't do anything for etching. Ok that said if the color is particularly stubborn definitely try making the poultice with hydrogen peroxide. And then repeat the application a couple times. If this doesn't do the trick you can also try making the poultice with mineral spirits. This solvent can help dislodge some compounds that aren't miscible in water.

@@TheGRITandPolish Thank you I will give the hydrogen peroxide a go when i get my hands on it, it is polished marble, but not to a mirror like finish, so hopefully a few goes with this will give me some joy...Many thanks

Oh so sorry to hear that Safiya! Sunlight liquid is an acidic detergent cleaner and likely etched the surface of your black marble. If the spot where the liquid looks dull and a little rough then the marble surface has actually been dissolved by the acids in the cleaner and there's no good way to repair it short of re-polishing with diamond pads to bring the glossy finish back. : (

Use the poultice formulated with hydrogen peroxide The H2O2 will reduce the pink/purple permanganate to a colorless product.

Use this poultice with hydrogen peroxide in place of water. It may take more than one application. That said dog poo can be pretty acidic and depending how long it was in contact with the floor it could actually dissolve the marble! If that's the case then there's no way to restore the finish short of wet polishing.

Turpentine would work especially well for oil-based stains

This baking soda poultice should help remove stains from cosmetics. Makeups (especially the creams) can have both water and oil-based components so first try a baking soda and hydrogen peroxide combination. This will remove the water-based colorants and then if the stain is still noticeable try baking soda with mineral spirits. This one will remove the oil-based portion of the stain.

Yes! Most of the time a darkened spot will be present once the poultice has been removed. This is due to water absorbed into the marble and it will evaporate away over a day or 2.

Thanks for sharing hector it sounds like you were able to restore the polished finish on your marble using wet sandpaper and a buffer. This method only works to remove colored stains so if you do have dull spots from an acid like lemon juice, you'll need to do something similar to what you did with the fine sandpaper

Yes I would use hydrogen peroxide to make the paste as it should oxidize the dye in addition to drawing it into the paste. You can also repeat the process a few times as there's no downside. But make sure the surface has been well cleaned before adding the poultice so more dye doesn't diffuse into the marble

Sorry to hear that Melissa! It's not likely that heat alone will cause discoloration on marble. Most likely it's hot residue on the bottom of a pan that gets absorbed in the stone. If this is the case I would use dish soap and a plant fiber scrubber like this one amzn.to/2RNBxiA to see if the residue comes off. After this step I would try the poultice, first with hydrogen peroxide and baking soda and then also with mineral spirits and baking soda. These two poultices will remove water-soluble organic stains and oil-based organic stains respectively.

Acids (like vinegar) can actually dissolve the marble in a process called etching which would result in a dull-looking spot. This can coincide with discoloration if the acidic solution had some pigment. The only way to restore the finish is using a diamond polisher. however the pigments could be removed with the baking soda-peroxide solution.

Hi Abhay. You've already identified that there are actually a couple important factors in this stain: the puke and acid! For the puke part I think this baking soda poultice is a perfect place to start. It is suited for removing organic stains such as those from chewed and partially digested food. I would use hydrogen peroxide as the liquid instead of water for greater power. Make a generous amount of the poultice and repeat the application on consecutive days. I think you will see any color in the affected area fade considerably. Now for the second part. Gastric acids help break down our chewed food and are quite powerful! and if they land on marble watch out. Depending on how long the vomit was on the marble it could have dissolved some of the finish or even some of the marble tile leaving a rough patch. This type of etching won't be restored by this poultice and requires more specialized repair/refinishing.

Sorry to hear that Ritu! If there is a color present in the stain, try this hydrogen peroxide, baking soda poultice. If the it's just a dark spot, like it got wet, this should go away on it's own as water evaporates from the marble over a day or two.

It depends on what it causing the cup ring. If it's from some brown coffee or tea then this should work well. You can also sub hydrogen peroxide for water for extra stain removing power. But if the cup ring was caused by something acidic such as Coca-Cola, then the surface of the marble, especially if it's polished, may have been dissolved leaving a dull ring that can only be removed by refinishing the marble surface.

@@TheGRITandPolish thanks for replying! It’s for sure gotta be from something acidic. Is there a product you can buy to refinish it or does that involve buffing a layer off

It depends on what caused the water ring. If it's from a pigmented drink like say tea or wine and the tea seeped into the marble forming a brownish ring, this would be likely to help. However if it's from an acidic drink like some lemonade spilled little and the glass formed a lemonade ring then it won't work cause the ring is from the acid in the drink dissolving the marble thereby "etching" a ring in the table.

Hydrogen peroxide is a colorless water-based liquid with a pretty neutral pH so it works very well on marble, same for baking soda, colorless and neutral. Though keep in mind the poultice will leave a darkened ring where the marble is hydrated by the water. This will evaporate away after a day or so.

The greenish stains around the faucet are likely the result of copper present in the water that has leached into the marble and oxidized to form copper carbonate. Normally you would remove copper carbonate with an acid but this would likely damage the marble in the process. The hydrogen peroxide paste could help lighten the stain and there's no downside there so give it a go. The trick is to remove the copper and another thing to try is a poultice of baking soda and L-cysteine which is an amino acid that chelates copper.

Hi Amrit. I haven't yet been able to find out what is in Harpic but my suspicion is that it has some acid. Another commenter had a blemish from Harpic spill on their marble floor. Your description of a faded spot sounds to me like the polished marble finish has been etched away by the Harpic. This poultice is most effective for removing stains from organic sources (yellow spot from turmeric for example). If your marble has been etched by acid in the Harpic you will need to re-polish to bring back the shiny finish.

You can try the water poultice first since it's the gentlest method, and if that doesn't work go with the hydrogen peroxide.

@@TheGRITandPolish Thank you so much!!! The hydrogen peroxide worked so beautifully after I tried the water and baking soda poultice three times. Do you you have any suggestions for granite that was etched by toothpaste water marks? I really appreciate your time and advice.

Ajax powder creates a slurry with a high pH when mixed with water. This could dissolve the marble so I would stick with baking soda and hydrogen peroxide or water to start. Then try other options if that doesn't work.

A stain remover has stained your marble floor! I would use this poultice a couple times in a row. This will pull out the water-soluble components of the Harpic. Then I would substitute mineral spirits for water and this should pull out the detergents and oil-soluble parts of the detergent.

This mixture works well for organic stains so should be good for wood stains

Hi Addy. So soy sauce is slightly acidic and could actually dissolve the marble. What you may be seeing is actually an etch mark from the lactic acid in the soy sauce and would look like a slightly dull spot in the glossy surface of the polished marble. Maybe this is what you are seeing?

If the water + baking soda doesn't remove it I would try hydrogen peroxide + baking soda. Make a generous amount and let it sit overnight on the stained area. If your stain is from a natural organic source like flowers or food, this should do the trick!

No this probably won't work for a burn mark. : (

Oh so sorry to hear that! Lemon juice and marble are not such a good combination! The acidic lemon juice can actually dissolve the marble creating a rough patch that has a noticeably different appearance than the polished or honed finish. Is that the case with your stain? If so you would need to re-polish that spot with a diamond pad to restore the look. Unfortunately this marble poultice does not help with acid etched marble.

Marble and natural stone in general does pretty well vs. heat! I place hot pans on our marble counters regularly. One reason you see marble as a fireplace surround is that it resists discoloration and cracking due to heat.

The GRIT and Polish Thank you

Oh interesting! This is a new one ; ) but given that the yellow stain is from an organic source I think this method should work well. I would use hydrogen peroxide if you have some handy. Otherwise try with water and see what happens. You can always try it again with hydrogen peroxide if needed. The nice thing about this method is that it's very gentle and you can use repeat applications for stubborn stains.

@@TheGRITandPolish I will try this and come back with an update. Thanks so much for getting back to me. I appreciate that so much.

Update: Neither method worked. 😔

You’ll probably have to buff it out with scotch bright pads on a rotary tool (other videos demonstrate it).

@@mulliganstew72 thanks, Mimi!! When i get around to it I'll provide an update.

Yes the darker spot is from the water in the poultice and it should evaporate out naturally within a day or two. You can speed the water removal by adding dry baking soda over top or just setting up a fan to blow over the spot.

This poultice works best on pigmented stains. Water marks can result from different causes that need different approaches. If it's a dull-looking ring in a highly polished marble surface no amount of scrubbing will restore it since the surface has been dissolved away in a process called etching. But if it's a ring from surface mineral deposits try giving the rings a scrub with clear detergent and cotton cloth or gentle scrubber (plastic or natural fiber). If your marble surface is honed, you can use a metal scrubber. Test out your method on an inconspicuous spot if you can. You can also check out the other video I did on removing some faucet rings on our marble vanity. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ibmdXY6DdVo.html

This poultice is an excellent way to remove the turmeric coloring! Use mix hydrogen peroxide and baking soda and let it sit over night on the stain. Scrape it off in the morning and you should notice the stain is either gone or much lighter and you can repeat if needed.

Haha.. Typical problem in Indian kitchens ! I sprayed normal all-purpose cleaner and wiped it instantly. If its a strong dried stain, it might take time to go

Stain that are "locked in" by sealer will be harder to get out. But if no sealer has been applied or if the stain is after sealer has been applied should be easier.

There's no reason a poultice would not work on cultured marble. However these are generally more durable, less porous, and harder to stain than natural marble. This might mean it's also harder to get the stain out. So I would make the poultice with hydrogen peroxide and repeat the application a few times if needed.

Oh dang! I don't think this will work for your situation. The Clorox wipes have citric acid as an ingredient and acids (as well as bases like bleach) can actually dissolve the marble. This is mostly likely what has happened to your table. The dull "fog" is from the polished marble finish being dissolved. On the bright side, since it's a table and not a countertop or floor tile you can take it to have it re-polished!

Oh dang yah the wax will likely need some heat to liberate the black dye that has been pulled into the marble. First I would try a dry cotton terry cloth (like a washcloth) and some heating with an iron directly on the spot. You could also heat the marble before applying the washcloth/iron with a hair dryer to make sure it's getting warm. This will pull any surface level wax off and then while it's still warm I would apply a poultice of clear dish soap (~1/4 tsp/cup of poultice), baking soda and mineral spirits, also warm, in the hopes of getting the wax out.

@@TheGRITandPolish thanks for your reply, I will try ASAP!

¯\_(ツ)_/¯

Thanks Gale!

I would try this with the hydrogen peroxide and baking soda and then if the blue persists, try it with mineral spirits and baking soda. This should do the trick!

De nada Guicho! Me alegro de que haya sido útil

This is a really gentle method applicable to any natural stone. That said granite is more dense and less porous than granite so it may not draw stains out as well.

Like acids, highly alkaline liquids like bleach can dissolve the carbonate minerals that make up the stone. When you notice a "stain" from these liquids, it is actually a spot of dissolved marble and the only way to remove the spot is by repolishing the surface.

@@TheGRITandPolish thanks will do that

For a marker stain I would try something like acetone or Goof off. Make sure you dab a little on an inconspicuous spot to be sure it doesn't harm the existing finish. Let us know if it works!
