Marble Counter Top Maintenance

Marble is a “relative” of limestone, having been derived from that particular stone, and having undergone further development while deep in the earth over the course of millions of years. Marble is a metamorphic rock, having been subject to tremendous heat and pressure to the point where various fossilized materials, along with the original limestone and sundry minerals, have become re-crystallized. This process changes the rock from limestone to what we would recognize as marble. This naturally decorative material is characterized by vein-like patterns which vary depending on which minerals, and which quantities of those minerals, were present during the re-crystallization of the original limestone parent rock. These patterns offer the unique appearance known to many, as well as the rich range of colors that are some of the most vibrant available in any natural stone.

Available in a wide range of colors, marble is often used for its beauty, but is more porous, softer, and chemically sensitive than granite. Marble surfaces show wear sooner than granite, but can be restored with honing and polishing more easily. Etched by acids, including soft drinks and juice. Absorbs oils and other liquids and is easily stained. So putting marble in a kitchen or heavily used bathroom is not a good idea. Best use of marble is for powder baths, table tops, tub surrounds, a marble shower, floor tile and stone fireplace surrounds.

Composed of Calcite and Calcium Carbonate. Should be sealed with a penetrating sealer such as BulletProof™ or Impregnator Pro to prevent staining and reduce soiling. Should only be cleaned with neutral pH detergents such as Revitalizer™ or Stone & Tile Cleaner. Because it is soft, it should never be cleaned at pressures above 800 PSI and then only if the grout is in good condition.

Note that almost all Green Marble is actually Serpentine, not Marble. Black Granite is generally Basalt and is charged a higher import duty.

Marble ranges from 1 to 4 on the MOH scale (a scale for determining the relative hardness of a mineral according to its resistance to scratching). The hardest mineral, at 10, is diamond. The softest mineral, at 1, is talc (baby powder).

Black Marble, such as Negro Marquina, is a very soft limestone often mistaken as a marble. Not recommended for interior flooring. Never use a crystallizer on black marble – The stone will blister or spall! If honing or polishing, use extreme care not to leave swirls and do not run until the powder has dried. Check frequently – polishes very quickly!

If you would like to test your floor or sample of Absolute Black Granite you can use both StoneTech™ Professional Restore™ and StoneTech™ Professional KlenzAll™ as testing liquids. We recommend you apply each of these cleaners in separate inconspicuous areas, let them stand for 30 minutes, rinse the surface and allow to dry. If the surface turns light gray you should avoid purchasing or using the material.

Stone Finishes

  • A polished finish on the stone has a glossy surface that reflects light and emphasizes the color and marking of the material. This type of finish is used on walls, furniture tops and other items, as well as floor tiles.
  • A honed finish is a satin smooth surface with relatively little light reflection. Generally, a honed finish is preferred for floors, stair treads, thresholds and other locations where heavy traffic will wear off the polished finish. A honed finish may also be used on furniture tops and other surfaces.
  • A flamed finish is a rough textured surface used frequently on granite floor tiles.

WDO's and DON'Ts for Marble

  • DO clean up spills immediately to minimize damage to your stone.
  • DO use trivets or mats under hot dishes and cookware.
  • DO use place mats under china, ceramics, silver and other objects that can scratch the stone's surface.
  • DO use coasters under glasses, especially if they contain alcohol or citrus juices.
  • DO clean surfaces regularly with StoneTech™ Professional Revitalizer™ Cleaner & Protector.
  • DO use StoneTech™ Professional BulletProof™ Sealer to protect the stone.
  • DO use a tray for toiletry products in the bathroom to protect the surface from the damaging chemicals contained in many toiletry products.
  • DO dust mop marble floor tile regularly.
  • DO use door mats inside and out along with runners and area rugs on marble floors.
  • DON'T wait to clean up spills on stone.
  • DON'T use cleaners that contain acid such as bathroom cleaners, grout cleaners or tub cleaners.
  • DON'T use vinegar, bleach, ammonia or other general-purpose cleaners.
  • DON'T use abrasive cleaners such as dry cleansers or soft cleansers.
  • DON'T use alkaline cleaners not specifically formulated for stone.
  • DON'T use scouring powders and abrasives because they will scratch the surface.
  • DON'T Place toiletry products directly on the countertop surface.

Care & Maintenance of Marble Countertops and Floors:

Marble is porous, and easily stained and is etched by acids. Avoid setting beverage glasses directly on marble as they leave rings. Fruit juice, carbonated beverages or other acids will etch (remove shiny surface) if allowed to remain on marble. Wipe up acid spill immediately, and wipe surface with wet cloth. If surfaced is etched, polishing may be required.

Natural stone is very porous. The best way to prevent stains is to treat the surface with a protective sealer. The sealer fills in the pores and repels spills on the surface, allowing you time to completely wipe it away.

Dust mop interior marble floors frequently using a clean non-treated dry dust mop. Sand, dirt and grit do the most damage to natural stone surfaces due to their abrasiveness. Mats or area rugs inside and outside an entrance will help to minimize the sand, dirt and grit that will scratch the stone floor. Be sure that the underside of the mat or rug is a non-slip surface. Normally, it will take a person about eight steps on a floor surface to remove sand or dirt from the bottom of their shoes. Do not use vacuum cleaners that are worn. The metal or plastic attachments or the wheels may scratch the surface.

We recommend that you use care and maintenance products from StoneTech™ Professional, a DuPont company, that are specially formulated to protect and enhance the beauty of your granite. Once the stone is sealed, clean up is usually easy. We recommend that you use StoneTech™ Professional Revitalizer™ Cleaner & Protector. Revitalizer™ cleans with a gentle, pH-neutral formula that removes soils while reinforcing the original protective seal to help prevent future staining.

.Sealed versus unsealed marble

Although we usually think of stone as "hard," it is a porous material. Natural stone has varying degrees of porosity depending on the type of stone. If left unsealed, spills and everyday messes can easily penetrate the surface. The liquid eventually evaporates but the stain is left behind.

Removal of oily stains is easily accomplished with StoneTech™ Professional Oil and Stain Remover.

DuPont™ Fluorochemical technology, incorporated into StoneTech™ Professional BulletProof™ and StoneTech™ Professional Impregnator Pro, is the most advanced technology available, providing the ultimate shield against both water and oil-base stains. The micro-molecular formula actually bonds with the stone surface to deliver unsurpassed wear resistance and durability. And because the sealer reacts with the stone, you no longer have to worry about its porosity. It works on all types of stone, from ultra-porous Juparana Columbo to super-dense Absolute Black.
