How to Remove Water Spots from Marble Countertop

Posted on Thursday, May 22nd, 2014 by Govi Reddy

Marble in your home provides unparalleled beauty. If water spots mar your marble countertop, clean and polish the marble to restore its former perfection.

Because marble is a porous natural stone, use only an approved cleaning process to avoid damaging the marble surface.

Physical Characteristics of Marble

Marble is not only porous, it is also softer – especially when compared to granite. Marble hardness ranges from 3 to 4 on Mohs hardness scale while granite is at 6 to 7.

Marble’s main composition is Calcite which is a Carbonate that reacts with acidic compounds present in the harder waters and other food substances like orange juice, tomato juice etc. The reaction causes what is known as etching of marble.

Because of these physical qualities, marble will absorb chemicals and liquids, which can cause permanent staining and damage.

Marble surfaces might also experience a dulling or etching if you use the wrong products to maintain the countertop due to the porosity and calcite composition of the stone.

Benefits of Microfiber

Microfiber cloths are soft enough for cleaning marble safely, yet effectively. Because marble can scratch so easily, using microfiber cloths will ensure that you don’t damage the surface of the stone while wiping it clean.

Safe Marble Cleaners

Opt for a gentle cleaner that is pH neutral. Gentle dishwashing liquid and a soft cloth may be all you need for daily cleaning to remove water spots and other dirt. Plain water can also be effective for keeping marble spotless.

Other safe cleansers include acetone, which is suitable for dark marble colors. Hydrogen peroxide is suitable for light marble colors.

Some marble fabricators sell special marble cleaners designed to clean marble safely and effectively. Ask your marble supplier for a cleaner recommendation.

Cleaners to Avoid

Never use harsh chemicals on marble counters as you try to eradicate water spots. Avoid chlorine bleach, white vinegar, ammonia and any product that contains lemon juice or other citrus.

Abrasive chemicals that scour will scratch marble. Even baking soda can leave a dull etching behind on a marble countertop.

Drying with Chamois cloth

Before calling for help from a stone restoration professional, you might wish to polish your marble to remove any stubborn water spots. Spray the marble lightly with plain water and then dry it with a Chamois cloth. Chamois cloth is made with a very soft fabric made in the imitation of Chamois leather. You may be able to buy the cloth from home improvement stores. Rubbing with Chamois cloth will dry the surface and polish it at the same time. Chamois is exceedingly absorbent, which means that it will dry and buff the marble at virtually the same time.

Preventing Water Spots

While water spots are a manageable part of marble maintenance, you can prevent them with a few simple steps. Never allow water to sit on the marble surface. This can lead to mineral deposits building up on the marble over time as the water evaporates. If you institute a habit of always drying the marble counter to remove all moisture, water spots won’t be as much of an issue.
