Natural Stone and Quartz Countertops: Polished Finish
For daily cleaning use mild dish soap like Ivory®, warm water and a soft clean cloth. You can also use any water based spray cleaner such as clear vinegar formula Windex® or Natural Stone Cleaner 409® (as recommended by the Marble Institute of America).
If a film, smudges, or streaks develop, use vinegar diluted with water (1 part vinegar to 3 parts water) and a soft clean cloth to remove it.
Natural Stone and Quartz Countertops: Honed or Leather Finish
For daily cleaning of honed or leather finished stone or quartz products, use Countertop Magic® or mild dish soap with warm water and a soft clean cloth. All of the cleaners mentioned above can be purchased at most hardware stores.
Silestone® (excluding Silestone® Leather series) and quartz surfaces do not require sealing.
Natural Stone (excluding Soapstone)
Your countertops have been sealed prior to installation. Some stones will only need sealing every few years depending on the stone’s porosity and your daily use of the countertops. To determine if your countertop needs resealing, perform a “water test”. Learn how in the “Additional Information” section.
Few granite and most marble, limestone, and travertine require an immediate application or multiple applications of sealer by the homeowner. The natural porosity of these stones and its use in your home requires them to have more initial sealing.
To seal your countertops, stone sealers are available through various stone suppliers and hardware stores.
General Sealing Instructions (always follow the directions provided with your product.)
Sealer penetrates the stone, buying you time to wipe spills up. Sealer is not a lacquer type coating; therefore spills should be wiped up in a timely manner. Spills left over a period of time could seep into the stone and cause staining.
If you are uncertain if your stone needs to be resealed, perform a simple “water test”. Place some water onto your stone. If within 15-20 minutes the water begins to absorb into the stone, it is time to reseal. Wait for the water spot to evaporate before resealing.
It is extremely difficult to chip your countertop. In the event you get chip save the pieces, it can be repaired by a stone technician.
Even though it is extremely difficult to scratch granite and quartz surfaces, the use of a cutting board is recommended.
Granite does NOT harbor bacteria or mold. Tests conducted by the Hospitality Institute using e-coli contaminates show granite is second only to stainless steel in bacteria resistance.
Stains can be removed. Depending on the nature of the stain the most common method is a poultice of peroxide and cornstarch. This paste applied to the area and allowed to dry will pull the stain from the stone. Occasionally more than one application is required. For more information on stain removal please see The Marble Institute of America
Natural pits or fissures in the stone do not have anything to do with how porous it may or may not be.
Do Not use plumber’s putty or any oil based adhesives on your tops.
Do Not use Scotch-Brite®, scouring or steel wool pads, or any acid based cleaner on your countertops.
Quartz is more susceptible to scorching or cracking from high heat items. For added protection use a trivet or cutting board.
Etching. (Slate and most granites are acid resistant.) When acid comes into contact with a stone surface, a chemical reaction takes place that may cause etching. Sealing will give you time to wipe up spills but cannot stop the chemical reaction. Many household foods and cosmetics contain acids that can degrade a stone’s surface. Some acidic foods are: juice, coffee, wine, soft drinks, tomato based products, and lemons. Do not leave these items resting on your countertops for any length of time.
