How do I remove the discoloration and roughness around sink drain?

Our bathroom sinks are cultured marble and around the drains, the surface is rougher and discolored. I have tried scrubbing with a nylon scrub pad and pouring peroxide in the area. Nothing takes the ugly stain/roughness away. The sinks are only 7 years old. Does anyone have tips for cleaning the marble countertops?

    Try full strength white distilled vinegar. Plug your sink and pour enough vinegar, enough to cover the rough areas. Let sit at least 30 minutes... Longer would be even better. Before draining the sink, use your nylon scrub pad to clean the marks. Hope that helps.

    They only have a warranty life,span of 5 years. You must use it a lot with hot water, which believe it or not speeds up the deterioration on that kind of plastic. Not much to do other than replace. New cultured marble sinks today is a rip.off.

    I would try sprinkling the area with a layer of baking soda. Then spray on some hydrogen peroxide. Let it sit for several hours. Now scrub it clean w/a nylon scrubbie pad. Good Luck!

    I will try the vinegar and the baking soda/peroxide. One tonight and one tomorrow. If we had known that the cultured marble (highly recommended by the builder!) was so cheap and had such a short life span we would have gone for something better. Live and learn!
