There is nothing like the look of granite countertops. And when you have them in your kitchen, bathroom or other space, you’ll want to make sure they stay looking sharp. That’s why we recommend that you do some routine care and cleaning to keep them looking great for years to come.
When it comes to day-to-day use, you’ll want to 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 surface of many stones. Do not place hot items directly on the stone surface. Use trivets or mats under hot dishes and placemats under china, ceramics, silver or other objects that can scratch the surface.
Cleaning Procedures and Recommendations
Vanity Top Surfaces
Vanity tops may need to have a penetrating sealer applied. A good quality marble wax or non-yellowing automobile paste wax can be applied to minimize water spotting.
Bath and Other Wet Areas
In the bath or other wet areas, soap scum can be minimized by using a squeegee after each use. 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). You will want to be careful, though, because frequent or over-use of an ammonia solution may eventually dull the surface of the stone.
Food Preparation Areas
In food preparation areas, the stone may need to have a penetrating sealer applied. If a sealer is applied, be sure that it is non-toxic and safe for use on food preparation surfaces. If you have questions about that, you’ll want to check with the sealer manufacturer.
Outdoor Pool and 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.
Dust mop interior floors frequently using a clean, non-treated 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 particles that will scratch the stone floor. Be sure that the underside of the mat or rug is a non-slip surface. Typically, 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 or a mild liquid dishwashing detergent and warm water. Use a clean rag mop on floors and a soft cloth for other surfaces. Too much cleaner or soap may leave a film and cause streaks. Don’t 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. Don’t use scouring powders or creams since these products contain abrasives that may scratch the surface.
Know Your Stone
Natural stone can be classified into two general categories according to its composition; siliceous stone or calcareous stone. Knowing the difference is critical when selecting cleaning products.
