How to Clean Granite Countertops?

Granite countertops are a popular choice for many homeowners due to their durability and the elegant touch they add to any kitchen or bathroom. However, like any investment in your home, they require proper care and maintenance to retain their beauty and functionality over time.

This guide will walk you through the steps and best practices for cleaning and maintaining your granite Kitchen countertops, ensuring they remain a stunning feature in your home for years to come.

What are Granite Countertops?

Granite is a natural stone formed from cooled magma and composed of various minerals such as quartz, feldspar, and mica. This composition gives granite its unique and varied patterns, making each countertop one of a kind.

Granite’s porosity varies depending on its composition, which affects how it absorbs liquids and how prone it is to staining. This is why sealing granite countertops is a crucial part of their maintenance.

Daily Cleaning Routine

A daily cleaning routine is essential to preserve the aesthetic and integrity of granite kitchen countertops. Here’s how you can do it effectively:

  1. Remove Debris and Spills Immediately: To prevent stains, wipe up spills as soon as they happen. Use a soft cloth or sponge to gently blot the spill.
  2. Warm Water and Mild Dish Soap: For everyday cleaning, a soft cloth or sponge with warm water and a few drops of mild dish soap is sufficient. Avoid acidic cleaners, such as vinegar or lemon juice, and harsh chemicals like bleach or ammonia, as these can damage the granite.
  3. Rinse with Water: After wiping the counters with the soapy solution, rinse the cloth or sponge with clean water and go over the countertops again to remove the soap residue.
  4. Dry the Countertop: Use a dry microfiber cloth to wipe the countertop dry. This prevents water spots and streaks, leaving your granite looking polished and clean.

Deep Cleaning and Stain Removal

Occasionally, your granite kitchen countertops might need a deeper cleaning or specific treatment for stains:

  1. Baking Soda Poultice for Stains: For oil-based stains, create a paste of baking soda and water. For water-based stains, mix baking soda with a small amount of hydrogen peroxide. Apply the paste to the stain, cover it with plastic wrap, and let it sit for a few hours or overnight. Remove the poultice, rinse with water, and dry.
  2. Commercial Granite Cleaner: For more stubborn stains or deep cleaning, use a cleaner specifically formulated for granite. Follow the manufacturer’s instructions for application and rinsing.

Disinfecting Granite Kitchen Countertops

In times when disinfection is necessary, such as after handling raw meat, you can safely disinfect your granite kitchen countertops:

  1. Isopropyl Alcohol Solution: Mix a solution of 50% water and 50% 91% isopropyl alcohol. Spray it onto the granite and let it sit for 3-5 minutes.
  2. Rinse and Dry: After the solution has sat, rinse the countertop with water and dry it thoroughly with a clean cloth.

Sealing Granite Kitchen Countertops

Sealing is crucial for protecting granite from stains and prolonging its beauty:

  1. Test the Sealant: To check if your countertop needs resealing, drop a small amount of water on the surface. If it beads up, the seal is good; if it soaks in, it’s time to reseal.
  2. Choose the Right Sealant: Use a sealant recommended for granite. Avoid general-purpose sealers that might not provide adequate protection.
  3. Apply the Sealant: Clean the countertop thoroughly before applying the sealant. Follow the manufacturer’s instructions for application, usually involving applying the sealant, allowing it to penetrate, and then wiping off the excess.
  4. Frequency of Sealing: The frequency of sealing depends on the usage and type of granite. It can range from once a year to every few years.

Tips for Maintaining Granite Countertops

  1. Use Coasters, Trivets, and Cutting Boards: Although granite is durable, it’s best to use coasters under glasses, trivets under hot pots, and cutting boards when chopping to prevent scratches and etching.
  2. Avoid Sitting or Standing on Countertops: Granite can crack under excessive weight, especially at weak points like sinks or cooktops.
  3. Regularly Check for Cracks and Chips: If you find any, seek professional help for repair to prevent further damage.
  4. Be Mindful of Heavy Objects: Avoid dropping heavy objects on granite as they can cause chips or cracks.
  5. Use SoftCloths or Sponges: Abrasive pads can scratch the surface of the granite.


Properly cleaned and maintained granite kitchen countertops not only enhance the beauty of your kitchen or bathroom but also add to the value of your home. By following these simple yet effective tips, you can ensure your granite surfaces remain as stunning as the day they were installed.

Remember, the key to keeping your granite in excellent condition is regular cleaning, proper sealing, and avoiding harsh chemicals and abrasive materials.

With these practices, your granite countertops will continue to be a durable and beautiful feature in your home for many years.
