I have a goose feather down comforter that needs to be cleaned. It is also pretty lifeless, very flat compared to how it was when purchased 3 years ago. The dry cleaners want $32 to clean it. Have any of you ever had this done? Will it add new life into the comforter, or just simply make it cleaner? I think I paid $99 originally, so I am wondering if I should just go ahead and buy a new one.
