Granite countertops are the crowning glory of many kitchens and baths, but their continued beauty depends on proper everyday cleaning and periodic maintenance. Granite is a natural stone that is porous and should be protected with an impregnating sealer once a year. Despite its hardness, there is still a need to clean spills up to prevent discoloration. Oil-based spills, acids, inks and dyes can stain granite and must be wiped up immediately, particularly on lighter shades of granite. With good habits and minimal effort, you will enjoy your countertops for years to come.

Daily

Wipe up all spills as soon as they occur, paying close attention to oily or acidic substances, like lemon juice or ketchup, that can etch the surface. Do not leave soiled dishes, pots, glasses or salad bowls on the counter, as this may create rings on the granite. Clean the counters with a granite cleaner or a small amount of warm water and a pH-balanced dish detergent. Contrary to the advice of some contractors, do not use Windex, 409, Pledge or anything abrasive. To do so will damage the polished finish. Surprisingly, even the green side of a scrubbing sponge scratches the finish. Never use granite surfaces as cutting boards. You will dull your knives and damage the finish, making it more difficult to keep the counter clean.

Stain Removal

You can remove oil stains by applying a poultice of baby powder and acetone, mixed to the consistency of fudge. Spread it on the stain 1/2" thick and cover it with two layers of Saran Wrap. Tape the Saran Wrap down all around the edges and do not disturb the poultice for 24 hours. During this time, the acetone will loosen the oil so it can be absorbed into the baby powder. Do not peak before the time is up or you will interrupt the process. After removing the poultice, clean, dry and reseal the area. Let it dry before use.

Sealing

Clean and dry your granite thoroughly before applying an impregnating sealer every year. Follow the directions on the label to get the best results. Do not apply too much sealer. Doing so can create a sticky surface that will grab dirt and will become dull. Do not use a sealer that does not move down into the granite (impregnate); it will build up on top of the granite and dull over time. Eventually you will need to strip it and reapply an impregnating sealer instead.
