Dear Rabbi,

How do you properly dispose of a menorah you no longer want/need? (I bought a nicer one.)

Dear Arthur P. Katz,

Though an item not used directly for a mitzvah (such as a talit, without the tzitzit), may be discarded, it just should not be treated with disrespect. Why not give the Menorah to someone poor, who cannot afford one, or to a child?
