How do I remove rust stains from a kitchen sink?

Question

I left an iron pan soaking in the kitchen sink and forgot about it. The pan left a small rust stain in the white cast iron sink. Is there anything I can do to get the stain out?

Comet/Ajax isn't up to the task. Any suggestions? Thanks.

Answer 1

either use a cleaning product made just for rust stains, or try lemons

Answer 2

Light rust stains can sometimes be removed by rubbing them with half a lemon. For heavier rust stains use a 5% solution of oxalic acid or a 10 % solution of hydrochloric acid, obtainable from a chemist. Wearing rubber gloves apply the acid with a soft cloth and rinse the sink thoroughly afterwards. This will rid the rust stain

Answer 3

Try a product called "Zud". It is a scouring powder that is tough on rust. There also used to be a product called "erusticator" but I don't know if that is available retail any longer. You might check with your hardware store.

One other is ceramabryte: http://www.ceramabryte.com/ I've never used this but heard it works.

Answer 4

Seems odd, I know, but try some WD-40. It's a great rust remover!

Answer 5

This is great for many household uses. I accidently sray painted my driveway, this took it off. It works on rust stains too.
