For a smooth, even surface, you should first buff the marble to remove any blemishes or scratches. You can do this by using a polishing compound or rubbing compound. You can also use paste wax to help shield the marble from future damage. 

You can also use a clear epoxy coating to repair your cultured marble countertop. This is a popular option, but be sure to check with the manufacturer of the product you’re considering before buying. You can also get do-it-yourself kits from companies like Lowe’s and Procaliber Products. These kits contain all the necessary tools to perform a thorough restoration. 

You can also use hydrogen peroxide to clean and remove stains. However, be sure to check for damage regularly. If the stains are permanent, you may have to hire a professional to repair your cultured marble countertop. 

Ideally, you should avoid the use of hot water or abrasive cleaners. These can actually damage the gloss finish of cultured marble. If you do want to use these methods, be sure to test them on a small area to ensure that they do not harm your marble. 

Some people recommend that you use a bleach solution to clean your marble. Be careful not to let the solution sit too long. You should apply it to the surface, and then wait eight hours before removing it. If you’re not sure how long the solution will stay on the surface, you should soak a cloth in it. After about half an hour, wipe the area to remove the cleaner. You can then rinse it off with soapy water. 

You can also use a liquid polishing compound to clean and polish your cultured marble. Make sure to test the product on a small area before attempting the full process. This is because it can be a messy and splashy mess. 

If you do decide to use a liquid polishing compound, you can use a wool buffing pad attached to a drill. Be careful to keep the pad perpendicular to the surface, and gently sweep the threads across the scratch. If you do this properly, you’ll be able to polish your marble to a glossy finish. 

You can also use a paste of Comet and water. Rub the paste into the surface in gentle, circular motions. You should then wipe it off with a cloth. 

Lastly, you can paint your cultured marble. Depending on the degree of the damage, this can be a great way to repair your marble. There are special paints for cultured marble, which are durable and stylish. Alternatively, you can just spray on a clear acrylic coat to fix the problem.
