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 placemats.
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.
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.
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.
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.
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). Frequent or over-use of an ammonia solution may eventually dull the surface of the stone.
Vanity Top Surfaces
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.
