Granite and marble countertops are not only elegant additions to any kitchen or bathroom, but they also require regular cleaning and polishing to maintain their beauty and longevity. These natural stone surfaces are porous and can be easily stained or damaged if not properly cared for. In this article, we will explore effective ways to clean and polish granite and marble countertops, ensuring they remain in pristine condition for years to come.

1. Understanding Granite and Marble

Before diving into the cleaning and polishing methods, it’s important to understand the characteristics of granite and marble. Granite is a type of igneous rock that consists of minerals like quartz, feldspar, and mica. Marble, on the other hand, is a metamorphic rock formed from limestone. Both granite and marble are porous materials, which means they can absorb liquids and become susceptible to stains.

2. Daily Cleaning Routine

To maintain the cleanliness of granite and marble countertops, a daily cleaning routine is essential. Follow these steps:

Remove Loose Debris: Begin by removing any loose debris or crumbs from the countertop surface using a soft cloth or a microfiber towel.

Gentle Cleaning Solution: Prepare a gentle cleaning solution by mixing warm water with a pH-neutral stone cleaner. It is important to refrain from using cleaners that are acidic or abrasive as they have the potential to harm the stone surface. Dip a clean cloth or sponge into the solution and gently wipe down the countertop, paying attention to any spills or stains.

Rinse and Dry: After cleaning, rinse the countertop thoroughly with clean water to remove any remaining cleaner residue. Dry the surface with a soft cloth to prevent water spots or streaks.

3. Dealing with Stains

Despite regular cleaning, granite and marble countertops may still develop stains. Here’s how to tackle common stains effectively:

Oil-Based Stains: For oil-based stains like cooking oil or grease, create a paste using baking soda and water. Ensure that the paste is applied thoroughly, covering the entire stained area. Let it sit for several hours or overnight, then gently wipe it away with a damp cloth. Repeat if necessary.

Organic Stains: Organic stains, such as coffee or wine, can be treated by making a poultice. Mix hydrogen peroxide with a small amount of ammonia and flour to create a thick paste. Apply the poultice to the stain, covering it completely. Cover the area with plastic wrap and let it sit for 24-48 hours. Remove the poultice and rinse the area with water, then dry it thoroughly.

Acidic Stains: Acidic substances like citrus fruits or vinegar can etch the surface of granite and marble. If an acidic stain occurs, gently rub the stained area with a soft cloth dipped in a mixture of baking soda and water. Rinse and dry the surface afterward.

4. Sealing the Countertops

Sealing granite and marble countertops is crucial to protect them from stains and damage. Sealing creates a barrier that prevents liquids from penetrating the stone. Follow these steps to seal your countertops effectively:

Test for Sealing: Before sealing, perform a water test to determine if your countertops require sealing. Gently distribute a few droplets of water across the surface. If the water beads up, your countertops are adequately sealed. If the water absorbs into the stone, it’s time to seal.

Clean and Dry: Thoroughly clean the countertops using a stone cleaner and ensure they are completely dry before applying the sealant.

Apply the Sealant: Follow the instructions on the sealant product carefully. Generally, you’ll need to pour a small amount of the sealant onto the countertop and spread it evenly using a soft cloth or sponge. Allow the sealant to penetrate the stone for the recommended time, usually 10-15 minutes.

Wipe Off Excess: After the recommended time, wipe off any excess sealant with a clean, dry cloth. Avoid leaving any streaks or smudges on the surface.

Cure and Repeat: Let the sealant cure for the recommended time, usually 24 hours. If necessary, repeat the sealing process to ensure maximum protection.

5. Polishing the Countertops

Polishing granite and marble countertops can enhance their natural beauty and create a glossy finish. Here’s how to polish your countertops effectively:

Clean the Countertops: Before polishing, ensure the countertops are clean and free of any debris or stains. Follow the daily cleaning routine mentioned earlier to prepare the surface.

Select a Polish: Choose a high-quality granite or marble polish that is specifically formulated for natural stone surfaces. Read the instructions on the polish carefully before proceeding.

Apply the Polish: Apply a small amount of polish onto the countertop surface. Use a soft cloth or a buffer pad attached to a low-speed polisher to work the polish into the stone in circular motions. Cover the entire countertop surface evenly.

Buffing: After applying the polish, use a clean, dry cloth or a different buffer pad to buff the surface in circular motions. Continue until the countertop achieves the desired level of shine.


Q: Can I use regular household cleaners on granite and marble countertops?

A: It is not recommended to use regular household cleaners on granite and marble countertops. Many household cleaners contain acidic or abrasive ingredients that can damage the stone surface and cause etching or dullness. It is best to use pH-neutral stone cleaners specifically designed for granite and marble. These cleaners are gentle yet effective in removing dirt and stains without harming the stone.

Q: How often should I seal my granite and marble countertops?

A: The frequency of sealing your granite and marble countertops depends on several factors, including the type of stone, its porosity, and the amount of use it receives. As a general guideline, it is recommended to seal granite countertops every 1 to 3 years, while marble countertops may require more frequent sealing, approximately every 6 months to 1 year. However, it is important to perform a water test periodically to determine if resealing is needed. If water no longer beads up on the surface, it is time to seal the countertops.

Q: Can I cut directly on granite or marble countertops?

A: While granite and marble are highly durable materials, it is not advisable to cut directly on their surfaces. These natural stones are prone to scratching, and using sharp knives or utensils can cause permanent damage. To protect your countertops, always use cutting boards or other protective surfaces when preparing food. This will prevent scratches and preserve the integrity of the stone. Additionally, be cautious with heavy or sharp objects that can potentially chip or crack the edges of the countertops.


Cleaning and polishing granite and marble countertops is essential for maintaining their beauty and longevity. By following the methods and tips outlined in this article, you can effectively clean stains, seal the countertops, and polish them to keep them looking stunning for years to come. Remember to always use appropriate cleaning products and avoid harsh chemicals or abrasive materials that can damage the stone. With proper care and maintenance, your granite and marble countertops will continue to enhance the elegance of your home.
