How do you remove tough stains from the bathroom sink?

Have you tried Magic Eraser yet? It does wonders!

I wonder if coke would work? This article was just posted on Hometalk and she used coke to get rust off of metal stool bases, but the same concept might work in sinks and for drains, I just might try coke in my bathroom, I have the same issue:

An in home steam cleaner works wonders on sink stains.

Try CLR (calcium, lime rust) Cleaner. Available Wal-Mart, Lowe's, giant.

you can buy white porcelain paint at the hardware store. I took a small artist brush and did lightly twice.

Fine grit sandpaper then fill with bleach and water let set until Stan is gone

You can try this but be careful and don’t let it set too long. Toilet bowl cleaner called The Works. That stuff has removed spray paint from brick when paint removers wouldn’t! Cheap and when done use it to clean your toilet.

bleach,vinegar,and bathroom cleaners do not work,I have tried it.Just a though which I have not gotten around to do you can try cream of tartar and some lemon juice.

Is Magic Eraser the Mr. Clean product with a sponge? If so, I have some and will give it a try later today. Thanks!!!

Try using regular tpothpaste and scrub, then rinse with wet rag

Thanks for the suggestion. I did try toothpaste and even used an electric scrubber on it, but it didn't do a good enough job. Thanks anyway.

I appreciate your taking the time to answer me.

Thanks Pattyann. I appreciate your response.
