Granite is an igneous rock that forms when magma cools slowly beneath the earth’s surface, forming large, easily visible crystals of quartz, feldspar, and mica. Scientifically, an intrusive (plutonic) igneous rock must contain between 10% and 50% quartz to be classified as granite, but other similar stones such as gabbro, diabase, anorthosite, sodalite, gneiss, and basalt are sometimes sold as “granite” commercially.
The granite quarried in North America comes mainly from the eastern and upper Midwest United States, but quarries can be found from coast to coast.
A wide variety of granites exist on the market, both foreign and domestic, and these can be drastically different in density, hardness, porosity, and aesthetics. Users should verify that the granite they plan to use is applicable to the demands of the project and has a successful history in such installations. ASTM test data is the most common data available to compare the properties of any stone, including granite.
The care of natural stones is specific to the type of stone that you have. Not all stones can take all cleaners. Granite is a much harder stone and can withstand almost everything you give it, but, marble is a softer stone and hates any acidic action.
The natural stone you have purchased for your home or office is an investment that will give you many years of beautiful service. Stone is a natural product and simple care and maintenance will keep it looking beautiful. This information will give you recommendations for routine cleaning as well as procedures for simple stain removal techniques, should they ever be necessary.
Care and Precautions:
Clean granite surfaces with a few drops of neutral cleaner, stone soap or a mild liquid dishwashing detergent and warm water. Use a clean, soft cloth. Too much cleaner or soap may leave a film and cause streaks. Always rinse with clean water. You can use Windex or other cleaners, but the rule of thumb is, if it has soap in it, rinse it off. A great granite cleaner is 1/3 vinegar with 2/3 water (windex without the soap- a lot less expensive too).
Spills and Stains:
Blot the spill with a paper towel immediately. Don’t wipe the area, it will spread the spill. Flush the area with plain water and mild soap and rinse several times. Dry the area thoroughly with a soft cloth. Repeat as necessary. If the stain remains, refer to the section of this brochure on stain removal.

Call your professional stone supplier for problems that appear too difficult to treat.
The natural stone your have purchased for your home or office is an investment that will give you many years of beautiful services. Stone is a natural product and simple care and maintenance will keep it looking beautiful. Here are some recommendations for routine care and cleaning.
Use coasters under all glasses, particularly those containing alcohol or citrus juices. Many common foods and drinks contain acids that will etch or dull the stone surface
You may place hot items directly on the stone surface. Use trivets or mats under hot dishes and place mats under china, ceramics, silver or other objects that can scratch the surface.
Cleaning Procedures & Recommendations
Dust mop interior 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.
Clean stone surfaces with a few drops of neutral cleaner, stone soap (available at hardware stores or from your stone dealer) or a mild liquid dishwashing detergent and warm water. Use a clean rag mop on floors and a soft cloth for other surfaces for best results. Too much cleaner or soap may leave a film and cause streaks. Do not use products that contain lemon, vinegar or other acids on marble or limestone. Rinse the surface thoroughly after washing with the soap solution and dry with a soft cloth. Change the rinse water frequently. Do not use scouring powders or creams; these products contain abrasives that may scratch the surface.
Bath and Other Wet Areas
In the bath or other wet areas, using a squeegee after each use can minimize soap scum. To remove soap scum, use a non-acidic soap scum remover or a solution of ammonia and water (about 1/2 cup ammonia to a gallon of water). Frequent or over-use of an ammonia solution may eventually dull the surface of the stone.
Vanity Top Surfaces
Vanity tops may need to have a penetrating sealer applied. Check with your installer for recommendations. A good quality marble wax or non-yellowing automobile paste wax can be applied to minimize water spotting.
Food Preparation Areas
In food preparation areas, the stone may need to have a penetrating sealer applied. Check with your installer for recommendations. If a sealer is applied, be sure that it is non-toxic and safe for use on food preparation surfaces. If there are questions, check with the sealer manufacturer.
Outdoor Pool & Patio Areas
In outdoor pool, patio or hot tub areas, flush with clear water and use a mild bleach solution to remove algae or moss.
Do's and Don'ts
· Do dust mop floors frequently
· Do clean surfaces with mild detergent or stone soap
· Do thoroughly rinse and dry the surface after washing
· Do blot up spills immediately
· Do protect floor surfaces with non-slip mats or area rugs and countertop surfaces with coasters, trivets or place mats
· Don't use vinegar, lemon juice or other cleaners containing acids on marble, limestone, travertine or onyx surfaces
· Don't use cleaners that contain acid such as bathroom cleaners, grout cleaners or tub & tile cleaners
· Don't use abrasive cleaners such as dry cleansers or soft cleansers
· Don't mix bleach and ammonia; this combination creates a toxic and lethal gas
