Marble and limestone

Marble and limestone are closely related. Marble is in fact crystalised limestone. It is a porous material, relatively soft stone and susceptible to etching and staining if you don’t protect it carefully. In general, you must avoid acid solutions coming into contact with marble, applies to cleaning products as well (vinegar, lemon juice or other cleaners containing acid).

Wiping the surfaces with warm water and a nonabrasive sponge or soft cloth is the best method for cleaning but will not remove etching or stains that have had time to permeate the surface.

Do not use:
1. Do not use bleach, ammonia, general-purpose cleaners or abrasive cleaning agents.
2. Do not use cleaners that contain acid such as bathroom cleaners, grout cleaners or tub and tile cleaners.
3. Do not use alkaline cleaners not specifically formulated for natural stone.
4. Don’t leave pools of water on marble surface, as this could end up leaving a stain.

What you can use:
1. Marble and limestone surfaces can be treated with a special anti-stain and anti-oil product.
2. Professional refinishing is recommended to remove etch marks and restore the stone's natural finish. However, if you don’t have access to it, you can manually remove stains.

If a stain is particularly difficult, use a soft scrub pad to buff out the stain and wipe it with a cloth to remove the dust.

Finally, you may apply a stone sealant to re-establish protection on the affected area. If you choose to seal your marble or limestone, use a quality product and follow the manufacturer's directions for use.
(Marble stone sealants can be purchased at almost any home improvement center.)

Do not, under any circumstances, use abrasive or aggressive products, acidic detergents, bleach, abrasive paper or steel wool.
