One great way to think of how to explain how porous marble can be is to compare it to our own skin.  If we were to get a wound that became infected, we would need to place a poultice on it to draw out the infection so that it does not spread and can heal.  A poultice on a stain in marble works the exact same way.


Though the recipe for pastes will vary since it depends on the type of stain that you are trying to remove, but the method of how the poultice is applied is the same.


Sometimes you cannot be certain exactly what type of stain may be staining your marble, but the color of the stain can give you an idea.  One of the more difficult of stains to remove are rust stains, especially old ones.  If you find that you have tried to remove the stain a few times and still have no luck, it may be time to bring in a professional.


One tidbit is that it is always best to test a small area that is not very noticeable to make sure that the cleaning method that you are using does not cause damage.


You only need a few materials:

  • Paper towels
  • Small bowl
  • Plastic wrap
  • Masking tape
  • Hydrogen peroxide
  • Ammonia


Tear small pieces of the paper towels into the bowl and follow that with a few drops of ammonia and enough hydrogen peroxide to fully soak the pieces of paper towels.


You will then take the small bits of soaked paper towels and place them all over the stain.  They need to be fairly saturated so that they will stick to the marble with ease.


After that, cover the entire area with plastic wrap and secure it in place with the masking tape.


The drying process can take anywhere from 2 to 3 days to completely dry.  The poultice needs to sit long enough to be able to pull that stain from the marble into the poultice itself.  You very well may not see any results within the first 24 hours and may even need to repeat this process a couple times.


Once the bits of paper towels have fully dried, remove them with the aid of a clean, soft cloth and warm water.  If you notice that some of the stain has been removed, you may need to try this process a second time.


If you find that using this type of poultice is harmful to your marble, you can also try a paste with baking soda and warm water.  You just apply it without the paper towels but still over with the plastic wrap and masking tape.  Make sure to allow it to completely dry before removing it with warm water and a soft, clean cloth.


If these steps do not work, then it is time to bring in a professional who is better equipped to removing stains.
