Granite countertops are a beautiful addition to a home. The natural stone really adds a touch of elegance and warmth to a room. Granite counters require proper care and cleaning to maintain their stunning surface and lasting beauty. Granite is a natural porous stone and is not impervious to scratches and stains. A common kitchen stain on a granite countertop is a grease/oil-stain. Cooking oil spatters or salad oil spills should always be wiped up immediately from the countertop surface. Any oil and grease that is not wiped off the countertop right away will seep into the stone and cause a stain. The longer the oil-stain remains, the farther it will seep into the granite surface and beyond. Prevention is always best, but not always possible.

Removing Oil and Grease Stains From Granite

The best way to remove oil or grease stains from a granite countertop is to make a poultice to draw the stain out. A poultice is a stain removing paste that sits on the stains for a length of time and works to absorb and remove grease or oil from the granite.

Work in a well ventilated area, wear protective goggles and gloves for safety.

Making a Grease and Oil Removing Poultice

Buy powdered white chalk which is available at paint stores, home improvement stores and hardware stores.

Place the white powdered chalk in a shallow glass container or jar, slowly add acetone and stir continuously with a wood stir stick such as a popsicle stick or tongue depressor until it forms a fairly thick paste. The paste will be about the same consistency as toothpaste. Acetone is also available at hardware stores, home improvement stores and paint stores.

Use a paint stirrer or tongue depressor to spread a thick layer of the mixture on the grease/oil-stains. Spread the poultice beginning at the outer edge of the grease/oil-stain and work toward the center of the stain.

Place plastic wrap or lay a plastic garbage bag over the paste on the granite.

Use tape to tape down the edges of the plastic to stop the acetone from evaporating. Make sure all edges of the plastic are taped down. Use a light tack masking tape such as blue painters tape.

Leave the poultice in place for at least six to eight hours, overnight is best.

In the morning or after six or eight hours, remove the light tack masking tape and plastic wrap.

Discard the plastic and tape.

Wipe the white powdered chalk and acetone poultice off with a clean, dry rag. Begin at the outer rim of the grease/oil-stain and wipe toward the middle fo the stain.

Use a second clean, dry rag and vigorously rub the area where the grease/oil-stains were.

If any stains remain on the granite countertop, mix a new poultice and reapply it to the grease and oil-stains. It may take two, three or more times to remove the stains. Keep reapplying the poultice if the grease/oil-stains lighten after each application. If the stains no longer lighten, they most likely won't come out, but most times a poultice is a successful way to remove the stains from a granite counter.

Granite Countertop Tips to Prevent StainsApply a coat of wax made for granite to seal and protect your countertop from further grease/oil-stains. Reapply wax monthly or more depending on how much your countertops are used.

Apply a coat of sealant for added protection from stains.

If your granite countertops are not sealed, avoid cooking and preparing foods on the unprotected granite surface until you are able to seal the counters or have them seaed professionally.
