Restoring the dark brown finish to copper sinks
A discussion started in 2008 but continuing through 2020November 4, 2008
Q. I ruined two bathroom sinks spraying them with Lime-A-Way [affil. link to product info on Amazon]. We have high lime deposits in our water and I have soaked our shower head several times which makes the spray much better. I didn't even think when I sprayed the drain of my pretty dark copper sinks and immediately they were spotted and streaked with bright copper finish now. The shower head must be coated bronze because the solution didn't affect it. We don't have a gas torch and I'm very nervous about trying to restore the finish myself. What do you suggest?

A. Hi, Lou. Patina finishes can usually benefit from an artistic touch, which I lack, so I don't know about your ability to satisfy yourself on this, but Brass Darkening Solution [affil. link to product info at Rockler] is available for patina restoration situations like this.

Q. I bought a house with a copper sink in which the patina is completely gone from years of heavy cleansers. It has a hammered finish and the raised portions look ok and the indented hammered spots are a dark brown. The overall appearance is terrible. Am I able to grind away the dark spots and then keep it waxed for a more uniform look?Dan Copsey

Help I ruined my antique metal bathroom sinkSeptember 7, 2013 -- this entry appended to this thread by editor in lieu of spawning a duplicative thread
I used a metal cleaner on my antique bronze metal sink and it took out the color to a brassy streak. This is not an expensive vanity sink and so I don't know the type metal it is. Please help me restore it to a uniform color. Thanks

Brass Darkening Solution
A. Hi Marie. If the sink was initially a shiny copper color like a new penny, a copper or brass polish like Brasso [affil. link to product info on Amazon] should fix it, although it may take a few applications. If the sink had a dark brown antique finish you may not be able to get it dark brown again in a reasonable timeframe without re-applying some sort of patina chemicals, such as mentioned by Barry.

Q. Hello, my name is Angela Brown. My house keeper decided it would be a great surprise for me, to bring back the original copper color of my sink. She didn't know it was dark on purpose. The whole entire sink is now bright copper with no coating.
Is there someone I can hire to make it dark again? Or is replacement my only option?Angela Brown
