Make Your Marble Sink Look New

It’s easy to renew a cultured marble sink that has been scratched by abrasive cleaning.

Cultured marble sinks are made of a polyester resin, which has a surface coat of clear gel or onyx resin. And they can be restored using supplies from your local auto parts store. You’ll need to purchase a can of medium-cut rubbing compound and a can of paste wax approved for use on Corvettes. Corvette bodies are made of fiberglass and have a finish like your sink’s.

First, buff the surface with the rubbing compound. You can use a buffing pad on an electric drill. Then rinse the sink, and buff to a high luster with the paste wax. It’s best to polish your cultured marble twice a year.

If the surface is gouged or badly marred, you can hire a professional to sand the top and coat it with a catalyzed acrylic urethane. The cost of this service is about $12 per linear foot for a counter top and $55 per bowl inside the sink. Check the Yellow Pages under "Bathtub and Sink Refinishing."

When the surface of your sink is restored, use only nonabrasive cleaners on it.
