Step-by-Step Guide to Polish Granite Countertops

Step 1: Clean the Countertop

Start by cleaning the countertop to remove any dirt, crumbs, or grime. Use a granite cleaner that is pH-balanced. Avoid harsh chemicals like bleach, as they can damage the surface. Spray the cleaner on the countertop and wipe it down with a soft cloth or microfiber towel. Make sure the surface is completely dry before moving on to the next step.

Step 2: Apply Granite Polish

Once the countertop is clean and dry, apply a small amount of granite countertop polish to the surface. It’s important to use a product that is designed specifically for granite, as this will help protect the stone and maintain its shine.

Fred Hueston, known as the "Stone Doctor" and a renowned stone restoration expert, advises, "Using the right granite polish is key to maintaining the surface's integrity while achieving a beautiful finish."

Step 3: Buff the Surface

Next, use a soft cloth or a buffing pad to buff the granite surface. Start at one corner of the countertop and work your way across, using gentle, circular motions. The goal is to work the polish into the stone and bring out its natural shine. If you’re using an electric buffing pad, make sure to set it on a low speed to avoid damaging the stone.

Andrew Wilson, a contractor from Madison, Wisconsin, advises, "Regular cleaning with mild soap and water can help minimize light scratches and maintain the granite's smooth surface."

Step 4: Repeat as Needed

If your granite countertop is very dull or has deep scratches, you may need to apply additional coats of polish. Make sure to allow each coat to dry before applying the next. Repeat the buffing process after each coat for the best results.

Step 5: Seal the Granite (Optional)

If you want to protect your granite countertops from future stains or scratches, consider applying a granite sealer after polishing. This will help create a protective layer on the surface. Follow the manufacturer’s instructions for proper application.
