I've tried scrubbing it several times with bar keepers friend soft cleanser and although it improves, it never goes away completely and it always comes back....
Just a word of warning on this - I’ve had CLR ruin countertops and sinks by accidentally leaving it in contact with them for a long time, make sure you’re diligent about wiping up rings from containers and any drips - learn from my expensive mistakes!
Also test it in a hidden spot first to make sure it doesn’t dull the finish or something.
Edit: IMHO give the vinegar suggestion a go first, much less caustic
