You can polish countertops that have lost their looks, whether yours are made from concrete, granite, quartz, marble or another material, using the right tools and method.
Because over time, countertops become tired and dull, and it's no secret with how hardworking they are in our kitchens... So if want to remove scratches or light scuff marks to make them shine like new again, rest assured that there are remedies to your problems.
To get scratches out of concrete and the likes, you’ll need to clean countertops first. This way, you can check how serious the scratch is, and remove any debris before you polish countertops.
Then, Chris Alexakis, home expert and co-founder of Cabinet Select recommends you ‘Purchase the correct materials. This includes safety goggles and gloves. You want to make sure you protect yourself when doing any home repairs. As for the right type of materials, make sure they match the surface. Marble needs marble-specific polisher, quartz the same, concrete is entirely different, and so on.'
'Tread lightly and go slow,’ he adds. ‘Don't rush the job. Start with the mildest materials first. Soap and water, then the polish, then potentially abrasives. Don't go in guns blazing, you'll be surprised what gentle products can accomplish.’
How to polish concrete countertops and remove scratches
Concrete countertops can be restored if they’re looking dull or scratched.

A minor scratch in a concrete countertop could be fixed relatively easily as it might be the sealer that protects it from stains and etching that’s scratched rather than the concrete itself.
Clean the concrete countertop first using a mild dish soap solution. Rinse with clean warm water and dry with a lint-free cloth.
You can make the repair with an acrylic sealer applied with a fine artist’s brush, applying according to the manufacturer’s instructions. Remove any excess and allow to dry.
You’ll probably need to blend in the repair using a fine grade sandpaper. Wipe down to clean the area when you’re done.
If the scratches on a concrete countertop are more serious, restoration of the entire countertop is the answer. You will need to strip or sand off the sealer as well as filling any pits in the surface before re-applying sealer.

If your countertops have lost the shine they used to have, they can be revitalized with polishing. The problem could be that they’ve accumulated a film over time. Although you might be wiping them down daily, it’s worth using a specialist granite cleaner once a week to restore the shine.
Also vital is to apply it with a microfiber cloth, which won’t damage the granite. Work in sections and buff using a circular motion to make the granite shine again.
What’s called etching can also make granite countertops look dull. If yours is a polished granite surface (don’t use this method on other granite finishes), the answer is to use a specialist granite polishing paste, following the instructions on the pack.
Can surface scratches be buffed out of granite countertops?
Surfaces scratches can be buffed out of granite. However, if the scratch is deep or extensive you may need to conceal it instead (see below), or call in a professional restorer.
‘To remove small scratches on your granite countertop, use a mixture of three tablespoons of baking soda and one tablespoon of water,’ says David Shell founder and CEO of TradesmenCosts. ‘Rub the mixture on the scratch in a circular motion. Let the mixture sit for at least 15 minutes and wipe it down with a damp towel.’
If that doesn’t do the job or scratches are more serious, use dish soap in warm water to clean the scratch thoroughly, rinse to make sure you have removed the cleaner, then use a soft, lint-free cloth to dry the area.
Next, gently buff the scratch using #0000 steel wool. Work carefully in small circles, and check after a few minutes. If the scratch still looks as it did when you started, you’ll need to use another method (see below).
When you’re finished, rinse the area using a dish soap solution applied with a soft cloth to remove debris. Allow to dry.
Afterwards, check to see whether your efforts have taken off the seal of the granite by sprinkling the area with water. If the water beads, there’s no need to do anything else, but if the water has spread or left a mark after 10 minutes or so you’ll have to re-seal the granite for which you’ll need a granite sealer and which should be applied according to the manufacturer’s instructions.
For a deeper scratch in granite, you may need to conceal rather than buffing it out. If that’s the case, get an acrylic repair kit made for granite countertops. Apply as per pack instructions.
