Marble countertop like other natural stones countertops is gorgeous, but is porous and will soak in liquids that can leave stains (even sitting water can cause stains!). You should always wipe up any spills from marble as soon as you see them.
This porosity explains why it stains so easily, but it also explains why stains can be removed. In fact all that’s needed to remove a stain is to reverse the staining process.
Sponge; Cloth; Poultice; Plastic wrap; Tape; Cotton balls
Option 1: Baking Soda Stain Remover Poultice
1) Clean the marble with a soft sponge to absorb as much of the substance as possible.
2) Spray the stain with water.
3) Cover the stain completely with a paste made from baking soda and water (to the consistency of sour cream).
4) Cover with plastic wrap and leave the stain covered for at least 24 hours, till the baking soda will dry and pull up much of the stain.
5) Remove the poultice and wash area with mild soap and water.
Option 2: Powdered Whiting and Hydrogen Peroxide Poultice
1) Clean the marble with a soft sponge. Run the sponge under lukewarm water and squeeze out excess water until the sponge is barely damp.
2) Rub the marble gently and dry it with a soft cloth.
3) Make the poultice and prepare it for application. If you are using a powder as the poultice, mix it with the stain-removing chemical until it is the consistency of peanut butter.
4) Another alternative is paper as poultice soak in a chemical stain-remover.
5) Dampen the stain with distilled water. This will fill the porous surface of the marble and isolate the stain for chemical removal.
6) Apply the poultice to the stained area and cover the stain with plastic wrap.
7) Let the poultice dry all the way. This will allow the poultice to pull the stain from the marble.
8) After the poultice is dry you can remove the poultice from the stain by rinsing with water and drying with a cloth.
Option 3: Rubbing Alcohol Stain Remover Spray
1) Pour 1/8 cup of rubbing alcohol into a 16 oz. spray bottle.
2) Add a couple drops of liquid dish detergent then fill the bottle with water.
3) Don’t forget to shake it, before use.
4) Spray onto marble countertop stains and wash area clean.
Option 4: Corn Starch
1) Spray stain lightly with distilled water.
2) Apply a thick layer of corn starch over the stain.
3) Leave for 24 hours till dry.
4) Wipe up then reapply if needed.
Cover your marble countertops regularly with impregnating sealers.
Before applying a method of stain treatment, do a test spot first to make sure the stone’s color or finish won’t be affected.
Do not drag any weighted things to the marble countertops surface, because countertop surface will crack or scratch. In addition, keep mind never cut anything to the surface directly, it also scratch your marble countertops.
If the problem is serious in nature or too large in size, consider using the services of a qualified stone restoration expert in your area.
