Review on High-Quality Classic Copper Pitcher by Edward Perez

Sturdy, neat pitcher, but the inside bottom looks tarnished (corners/edges look dark and dirty). Tried using natural copper cleaning methods but to no avail. Cleaning the inside is not easy as the top cannot be removed. .have to use it as a water pitcher, but of course I can't. don't know what to do with it. it is thick copper .wish it would work for me
