Default Copper sink discoloration

I bought a brand new copper sink and accidentally left a bar of soap in
it. After about 4 to 6 hours, I removed the soap and noticed
discoloration, a grayish color, where the soap had been sitting. The
copper finish had transferred to the soap bar. The soap really is not
harsh.
How would I get rid of that discoloration and get the copper color
back?

Thanks!

Did you get any literature with the sink? I'm sure they would have a
suggestion. If you know the manufacturer, try Googling them. Either that or
try some Brasso or some other brass cleaner/polisher.....

Copper is a fairly reactive metal and is going to discolor from
numerous causes. Getting used to it could be the best course of action.

Copper is not a fairly reactive metal. It's non-porous and will not
stain.

Copper is very reactive, acid turns it green, the soap may be alkali and
affected it. Contact the manufacturer or store. It might polish out

Guys, guys...........let's not fight.

Depending on the environment copper can be considered "reactive".

Acid water conditions (fresh water) can each through it fairly quickly;
ie pin hole damage.

WIth typical SoCal doemstic water, copper plumbing can easily last
50yeas +.

A bare copper sink can be "stained / discolored" by a wide range of
stuff.

Maybe that's why SS is the typical choice for metal sinks not "chic
-chicy" copper.

cheers
Bob

Copper can be very reactive in the right chemical environment, such as
our plumbing system over about 20 years. After clothes & hair &
ceramic sinks going green She got fed up and all copper was removed
except basin taps (which etch away every two years). Now no more
green. My guess is the stain is a normally soluble copper compound and
the clothes & hair were coloured from copper stearate (soap). That
BTW is water from our well which is like cool, clear champagne to
drink, but is hell on copper.
