A marble-topped table can be a great way of adding some elegance and natural beauty to your home. Marble's variation and high shine can help to enhance any decor.

Marble is a natural stone and will require special care if you do choose to use a marble table. The wrong type of cleaner, lack of sealant or even just a coffee cup used without a coaster could discolor your marble. You will be able to lessen the appearance of these stains dramatically by using stone-care products.

Things You'll Need

  • Stone cleaner
  • Lint free cloths
  • Water
  • Poultice
  • Plastic wrap
  • Impregnating sealer
  • Foam paint brush

Clean the marble top well with a stone cleaner. Stone cleaners are available in spray bottles for ease of use. Spray the cleaner onto the table and buff with a lint-free cloth. This will remove any surface stains from the marble.

Apply a poultice to the marble top. Poultice is a paste used to draw out stains and discolorations from within the stone. It can be purchased at most stone yards and is available both ready mixed and as a powder you mix with water.

Spread the poultice over the discolored areas of the marble top and cover the poultice with a piece of plastic wrap to seal it in. Allow it to sit for one hour.

Rinse the poultice off the table with water and then clean the top again with a stone cleaner, buffing the top dry with a lint-free cloth.

Seal the marble top against further staining by painting it with an impregnating sealer using a foam paintbrush. Allow the sealer to penetrate for one hour and then wipe up the excess with a lint-free cloth.
