The copper on my feeder has lost its shine and is turning colors. What does this mean and/or what shouldI do?
You are merely seeing the natural aging of pure copper. With exposure to the elements, copper will dull and turn deep red, which adds to its patina and aged charm. However, if you wish to delay the aging process (preventing it altogether is not possible), you can apply a common household copper cleaner, then rinse thoroughly with tap water and pat dry with a cotton cloth. Afterward, apply two coats of clear lacquer on the copper. Remember to allow each coat to dry thoroughly.
