Removing green residue on copper pipes

Q. After learning exactly how this horrible green stuff is formed on our copper pipes, could you please give me a practical solution as to how I would remove it in order to paint the pipes, or whether you consider it unecessary to remove it before painting I.E can I just rub it down and paint them and it wouldn't seap through the paint. Thank you. P.S If there is a chemical I could use would you please explain how it works and the chemical processes it utilises.

A. Oh I believe you can use Goo Gone ⇦ this on eBay or Amazon [affil links] to remove what you need.
