Granite countertop stains can ruin the otherwise fine appearance of your kitchen or bathroom. Many homeowners opt for granite for kitchen and bathroom countertops. It is easy to clean, fire-resistant, and durable. However, stains can occur quite easily on granite.

Some common causes of these stains include water, oil, citrus fruit juices, beverage spills, wine, and ink. The damage is even greater on unsealed granite. It is best to remove stains as soon as you spot them. This will help maintain the attractiveness of your countertops. Different preparations can be used for different stains.

Mild Stain Removal

Mix 2 cups of rubbing alcohol together with 2 cups of water in a sink. Dip a rag into the solution and wring lightly. Rub firmly onto the stained area of the countertop until the stain begins to fade. Rub away as much of the stain as possible then rub the same area with a dry rag. It will help to complete the stain removal process.

Other Stains

You can create a poultice out of different products for more resistant stains on your granite countertop. Hydrogen peroxide works well for organic stains such as fruit juices, tea, and coffee. For ink and stubborn dirt, use rubbing alcohol or lacquer thinner. If you need to remove oil stains, use pure acetone in the poultice. Use bleach if you need to clear mold and mildew stains. Place a cup of talcum powder in a bowl. Slowly add the appropriate product for the specific stain you need to remove and mix with a fork. Mix steadily until you get a paste with the consistency of peanut butter.

Apply Poultice

Scoop some poultice with a dry rag. Apply a ¼ inch thickness onto the stain. Be sure the poultice covers the entire stained area and overlaps slightly. Cover with plastic wrap. Secure the edges of the wrap onto the countertop with some tape. Puncture a couple of holes into the wrap to enable the poultice to dry faster. Allow 24 hours for the preparation to work on the stain.

Clear the Poultice

Remove the plastic wrap and allow the poultice to dry completely. It could take anywhere from a few hours to a couple of days. Once it has dried completely, scrap away the poultice with a plastic scraper. Wipe the area with a damp rag. If the stain persists, you’ll need to repeat the process once or twice to completely clear the stain.


Wipe spills as soon as they occur. Once the liquid infiltrates into the stone, stains develop easily some of which can be difficult to remove. It's a good idea to seal your granite countertops. This will help to prevent stains and also maintain the integrity of the stone. Avoid harsh cleaners and abrasive materials when you clean your granite. These can cause discolorations and stains on your countertops. Use coasters and placemats as much as possible on your kitchen countertop. This helps to prevent spills.
