In general, CFM's stone surfaces are very strong, durable, and thus, can last a long time. However, there are some things that can help keep your stone surfaces in prime condition, and help it to last even longer.
Do's
When cleaning your stone surfaces, it is best to use warm water with a small amount of non-abrasive soap, and rinse clean with clear warm water. Lastly, dry thoroughly with a clean soft cloth. Your stone surfaces should be protected with coasters, trivets, or placemats.
When dealing with stone surface floors, the floors should be dust mopped frequently and spills should be blotted up immediately. Also, vulnerable areas on the floor should be protected with non-slip mats or area rugs.
Do Not's
Stone surfaces should not be cleaned using any substance that is highly acidic, such as vinegar or lemon juice. Also, highly abrasive cleaners such as dry cleansers or soft cleansers should be avoided. Under no circumstances should you mix chemicals unless directions specifically instruct you to do so. When bleach and ammonia are mixed a toxic and lethal gas is created.
Although natural stone is heat resistant, it may not withstand the direct transfer of heat from pots, pans, and other cooking units such as electric skillets, griddles, roaster ovens, heat lamps, and some crock-pots. Therefore, hot pads and trivets should be used.
Stone Surface Maintenance
Penetrating Sealers
An important factor in stone surface maintenance is sealing. To test if your sealer is working, place a few drops of water on your counter. If the water soaks in quickly or leaves a dark spot, then it is time to reseal. If it beads up, it is protected. At CFM, we use Regent Silicone Impregnator, which has three to five years of protection on interior surfaces.
Food Preparation Areas
In food preparation areas, the stone may need to have a penetrating sealer applied, be sure that it is non-toxic and safe for use on food preparation surfaces.
