How can I clean a stain around the bathroom sink drain?

I use white vinegar and dawn. I let it sit for a few hours and the stain is gone.

CLR and Lime Away are similar products that work on rust. This is a good opportunity to look closely at the source of the rust.

Those drain “collars” will lose their chrome plating over the years and will continue to rust until they leak and have to be replaced. If yours is at this stage, keep a bucket under the drain until you get the “collar” replaced.,

Hello. If barkeepers friend did not work, I would try a CLR product.

Hi Ann, I am attaching a few ideas for you to try, one is a video, hope one of them helps you out :)

For tougher rust stains, make a paste of two other pantry staples: three parts baking soda and one part vinegar. Apply it to the rusty surface with a scrub sponge, and let it sit for an hour. When you rinse it off, the rust should be gone, though, for more severe stains, you may need to repeat the process.

1. Sprinkle baking soda or scouring powder onto the stain and scrub it with a damp cloth or scrub brush. ...
2. Spray any stains with 1 part bleach to 4 parts water in a spray bottle. ...
3. Remove soap-scum stains with equal parts white vinegar and warm water

Feel the stain around your sink drain...is it rough like a calcium deposit? I had that on my faux marble sink and I shut the drain and put about a cup of vinegar in it. Let it set over night and the next morning it was much better, but still a little rough. I then took a nylon scrubbie and rubbed that around the drain, and it was smooth again and stain free. If I had a porcelain sink, I would have used a pumice stone but was afraid it would scratch the faux marble.
