Does Granite Stain

Does Granite Stain

A frequent question that homeowners ask is whether granite countertop stain or not.

Does granite stain? Yes, the answer depends on the quality of granite, and how well the granite is sealed after installation. Any time a liquid is allowed to sit on the countertop surface, you run the risk of the granite staining. Yes, your granite does stain but there are ways to prevent this from happening.

Know what substances to avoid around your countertops and if you accidentally spill any of these substances act quickly to clean them up even if your granite countertops are sealed properly.

 

Understanding the Porosity of Natural Stone

All natural stone countertops are porous; however, the porosity levels vary from stone to stone. Granite is one of the less porous types of stones. Lower porosity levels mean the stone will not absorb liquids as quickly as other stones.

Natural stones have pores that allow liquids to seep into the stone. When a liquid is allowed to remain on the surface of a stone countertop, it can enter into the stone and cause a stain. An impregnating stone sealer helps close these pores up to reduce the risk of staining.

 

How to Reduce the Risk of Staining on Granite Countertops

The first step in reducing the risk of staining is to seal your granite countertops with an impregnating sealer. Begin by cleaning your countertops with a granite cleaner and allow the countertops to air dry before applying the stone sealer. Follow the manufacturer’s recommendations on applying the sealer.

Apply the penetrating sealer using a soft, clean cloth, ensuring the entire countertop is wet. Allow the first layer of sealer to dry for five minutes and then apply additional layers every five minutes until you have reached the desired number of coats.

Apply a final coat and allow the sealer to soak in for thirty minutes. Then, wipe excess sealer off the countertop and allow the sealer to air dry for 24 hours. After the drying time, your countertop is protected against stains.

To ensure that your countertops are sufficiently protected, perform a water test after the sealer has cured and bonded to the natural stone. To ensure your countertops remain protected, a sealer should be applied every six to twelve months, especially in high use areas.

 

How to Remove Oil Based Stains on Granite Countertops

Oil based stains caused by oils, grease, cosmetics, and milk will darken the granite countertop. In order to remove the stain, the oil must be chemically dissolved. Apply household detergent, mineral spirits, acetone, ammonia, or bleach to the stain and clean gently. Then, flood the area with water and buff dry using a soft, clean cloth.

 

How to Remove Organic Stains on Granite Countertops

Organic stains, including coffee, tea, wine, and fruit cause pinkish brown stains to appear. You can remove these organic stains with a mixture of 12 percent hydrogen peroxide and ammonia. Wipe the stain using a cloth and allow the hydrogen peroxide mixture to sit for ten minutes before rinsing the countertop with clear water and buffing dry with an absorbent cloth.

 

How to Remove Biological Stains on Granite Countertops

Biological stains, including fungi, mildew, algae, and mold, should be cleaned using diluted (a half-cup in a gallon of clean water) ammonia, hydrogen peroxide, or bleach. Apply to the stain and wipe clean using a clean damp cloth.

 

How to Remove Ink and Paint Stains on Granite Countertops

Paint should be scraped off using a razor blade. Exercise care to avoid scratching the surface of the stone.  Ink can be removed using hydrogen peroxide or bleach. Rinse the area and wipe dry

 

How to Remove Water Rings on Granite Countertops

Water doesn’t actually stain; however, it can cause an artificial stain to appear. The water causes rings of granite sealer to appear. These water rings can be removed by applying denatured alcohol to the countertop and wiping in a circular motion. You will need to apply the alcohol several times because it evaporates so quickly.

 

How to Remove Soap Scum on Granite Countertops

If you clean your granite countertops with dish soap, a film will eventually build up. This can be removed using a soap film remover. If your countertops appear dull, it is probably due to soap buildup. Cleaning the countertop with soap film remover will restore the shine.

 

How to Make a Poultice to Remove Stains on Granite Countertops

If these methods do not remove the stain, you will need to use a poultice. The poultice is made by mixing an absorbent material like diatomaceous earth, talc, powdered chalk or baking soda with water or a liquid cleaner. The treatment is then applied to the stain and covered with plastic wrap. The poultice is left on the countertop for twenty-four to forty-eight hours. The liquid will pull the stain into the absorbent material.

Oil based stains can be removed using a combination of baking soda and water or talc and mineral spirits.
Organic stains are removed by mixing hydrogen peroxide with diatomaceous earth or powdered chalk.
Biological stains can be removed by mixing hydrogen peroxide or ammonia with powdered chalk or talc.

Stain removal also removes the sealer from the countertop. To protect your granite countertops from further staining, follow the instruction above, and apply multiple coats of penetrating sealer to the entire countertop.

 

Daily Maintenance for Beautiful Granite Countertops

Your granite countertops will provide you with years of beauty when they are properly cared for. Proper daily maintenance includes wiping your granite countertops down daily using a damp cloth. If you spill anything on your granite countertops, wipe it up immediately and clean the countertop using a pH neutral granite cleaner.

Granite countertops are extremely durable and resist stains quite well; however, staining can still occur. Wipe spills up immediately and routinely seal your granite countertops to reduce the risk of staining. If a stain occurs, follow the steps listed above. If a stain remains after using a poultice, contact your stone specialist for assistance.

Hi, my name is Jonathan Smith. I have been in the granite business for many years and have worked my way up from an installer helper to an installer and then a countertop business owner. I started my countertop company with very little and grew extremely fast because of my knowledge and helpfulness. I started this countertop resource for 1 main reason. That reason is that there are no countertop websites with all the correct information and none of them are from an industry expert like myself. I am still in the trade every single day installing countertops, educating people on the type of material they are using for their homes and making people's dream kitchens a reality.
