We have a 23 year old Kohler cast iron kitchen sink that we have taken
good care of - dont let coffee residue stand in the sink, etc.

Now we are getting brown-gray stains that do not come off with Soft Scrub.

Do you have recommendations for methods or materials that we might try?

Thank you very much.

I'd try one of the rust stain remove products, like
CLR that you can get at HD, hardware store, etc
With rust stains, I've seen them just disappear
instantly when you put the product on.

SWMBO just fills ours with hot tap water and a cup or two of bleach
and lets it site for a few hours.

You might also try water & vinegar if the bleach doesn't work.

fill the sink with warm water and then add a quart of bleach. Works
wonders. (let sit a while)

Even half a cup works well enough.

For me? After a sink that many years old, I would call a pro.

They can restore a sink in look like new, serviceable condition.

It only takes an hour or two for the fix. Looks better than new.

Exactly where are these stains? Are they in that area where the faucet
drips? Elsewhere?

CLR or equivalent. Harmless to porcelain, works wonders on mineral deposits
and rust.

Thanks every *one. Clorox did it.

For constant upkeep, use a paper towel with a squirt of Dial
antibacterial handsoap on it.

Using a swirling pattern, clean the sink. Not much water, almost dry.
You'd be surprised at the dark muck that comes off onto the towel.
Then rinse, Makes shiney, like new.

I've had good luck with those Magic Erasers -- they are safe, too.
