Keeping copper from turning green

Hello,

I have a cupola with a bright new shiny copper top. I have polished it with Brasso ⇦ on eBay or Amazon [affil link] . Can you tell me if there is anything I can apply to the copper to keep it nice and shiny as opposed to turning green?

Thanks so much!

A. A lacquer (clear) will prevent the copper from oxidizing and changing color. You might talk to G.J. Nikolas [a finishing.com supporting advertiser].

Q. I am interested in finding a quick way to oxidize copper to speed the natural process by which copper turns green over prolonged periods...any suggestions?

A. Erik,

Get swimming pool chlorine (stronger than store bleach) ⇦ in bulk on eBay or Amazon [affil link] and soak the copper for a day or so. Will turn green.
